Full textAbstract:
This paper examines the background, development and production of the film ‘Songs of the immigrant bride’ and explains the general decisions made throughout the creation of the film. It proposes the idea that visuals, combined in an abstract narrative with music/sound, can create a language outside that generally accepted in real-time film (generally) and animation (specifically) to create a communicating ‘mythopoetic’ film-style from combined, selected elements, of both genres. Some of the issues presented and examined are: how relevant background experiences and influences directed the image-making in the production of the film; the experimental use of symbols and metaphor for an ‘evocative’ narrative in both visuals and sound, and the use of these within the film; the relevance of the theme of journey to viewers of the film; the part played by ‘Chance’ as an accepted phenomenon in shaping the direction of the film; production considerations, other than those of image and sound, to enhance audience perception and understanding of the film; ‘understanding’, as a physical as well as an intellectual phenomenonMaster of Arts (Hons)

Nilsson, Kristian. "Film formation of latex in dry coating films." Thesis, Karlstad University, Faculty of Technology and Science, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:kau:diva-1048.
Full textAbstract:
The objective of this master thesis was to investigate the possibility to measure the gain in stiffness of the dry coating due to film formation of latex with a Dynamic Mechanic Thermal Analyzer (DMTA). This could tell when and to which extent the latex forms a film after the drying process.
Two latices with different Tg was used for the experiments, one with a Tg of 36°C, denoted hard, and the one with a Tg of 8°C, denoted soft. The hard latex was used to make coating samples that would not form a film when dried at room temperature and the soft latex was used as a reference to the coating with hard latex since it would form a film at room temperature.
It was shown that a gain in stiffness due to film formation of latex in coating can be measured with a DMTA. It was also shown that that the film forming of latex in coatings depend on time, temperature and the history of the sample. Further investigations were carried out to try to determine the time for film formation to be completed at a certain temperature.. These investigations showed that this type of trials cannot be carried out in a DMTA directly since the stiffness seemed to increase monotonically during a very ling time. This might be due to the rearrangements in the pigment structure that might affect the gain in stiffness. Therefore, a method involving oven curing was developed. Only one series of test were performed with this method due to lack of time but the method showed promising results.
Syftet med detta examensarbete var att undersöka möjligheten att använda en Dynamic Mechanic Thermal Analyzer (DMTA) för att mäta ökningen av styvhet som följd av filmbildning av latex i en torr bestrykning.
Två olika latexer användes för experimenten, en med Tg = 36°C (hård) och en med Tg = 8°C (mjuk). Den hårda latexen användes för att kunna göra tester på prover som ännu inte filmbildat när de torkat vid rumstemperatur och den mjuka latexen användes för att göra referens prover mot bestrykningen med hård latex.
Resultaten visade att det går att mäta styvhetsökning i bestrykningen som en följd av filmformation med DMTA och filmformation av latex i bestrykningen troligtvis beror på både tid, temperatur och provets historia. Ett försök att mäta vilken uppehålls tid vid en specifik temperatur som krävs för att filmbildningen skall fulländas genomfördes. Dessa försök visade att DMTA:n inte var en lämplig metod för att mäta denna tid då styvheten verkade öka under en längre tid. Detta kan bero på att pigment partiklarna packade sig tätare och på så sätt orsakade en ökning av styvheten. Därför gjordes ett annat försök som involverar ugns härdning, men på grund av tidsbrist blev det bara en mätserie utförd. Den sist nämnda metoden visade dock goda resultat och måste därför bedömas ha en potential.

Kohli, Gurdeep Singh. "Film or film brand? : investigating consumers' engagement with films as brands." Thesis, Brunel University, 2017. http://bura.brunel.ac.uk/handle/2438/16312.
Full textAbstract:
This study offers an in-depth account of how, when and why consumers engage with films as brands, using 38 exploratory, semi-structured consumer interviews and 1030 consumer survey responses. Extant film branding literature is scarce, dominated by filmmakers' and marketers' perspectives of films as brands and is confined to exploring points of parity associations films have as brands, rather than ways films may differentiate themselves as brands. Taking on a consumer centric view, our findings show although filmmakers, production houses and marketers may jointly develop and market films with the vision of becoming brands, this doesn't necessarily guarantee consumers' engagement with such films as brands. Instead, consumers initially evaluate the coherency of a film's identity and subsequently go on to engage with films as brands, a process which is fully mediated by the emotional bonding a consumer may develop for a film and partially mediated by a film's popularity and sequels. Films' marketing/franchising efforts, iconic status and sense of timelessness moderate consumer-film brand engagement, resulting in positive word of mouth and purchase intention. Our sequential, consolidated and specified film brand engagement framework guides filmmakers and marketers on how to tactically engage consumers with their films as brands, in order to differentiate themselves within this risky and competitive market.

Full textAbstract:
Malgré sa récente remise en lumière, le cinéma muet est toujours menacé de disparition, du fait notamment de la décomposition des supports nitrate avec le temps. On estime que 80 pour cent de la production cinématographique mondiale de 1895 à 1929 serait de nos jours perdue, rendant d’autant plus cruciale la restauration des films muets subsistants. Malheureusement, un siècle après, ces films se présentent souvent dans des versions incomplètes et parfois différentes de celles d’origine. Ce travail de recherche s’inscrit dans ce cadre et démontre plus spécifiquement l’apport fondamental des documents d’archives non-film d’époque dans les processus de restauration de films muets. Ces documents, qui constituent désormais les seules sources attestant de la forme d’origine et complète de ces œuvres, permettent notamment, par comparaison avec les films incomplets, l’identification des versions conservées et la reconstruction des trames narratives. Cette réflexion théorique sur les principes directeurs de la restauration de films [I] est ensuite mise en pratique au travers de notre analyse des éléments de restauration du fonds d’archives non-film de la société de production américaine Triangle Film Corporation (1915-1919) conservés par la Cinémathèque française [II] puis, grâce à l’exploitation de ces éléments, au travers de notre contribution aux restaurations des versions françaises du western The Desert Man (La Cité du désespoir, William S. Hart, 1917) et du drame historique The Despoiler (Châtiment, Reginald Barker, 1915) [III] ; deux films Triangle jusqu’alors considérés comme perdus qui constituent les seuls éléments filmiques localisés à ce jour dans le mondeDespite its recent re-lighting, silent cinema is still threatened by disappearance, notably because of nitrate film decomposition over time. It is estimated that 80 per cent of the world cinema production from 1895 to 1929 is currently lost, which makes silent film restoration even more crucial for those that still exist. Unfortunately, a century later, those films often remain in incomplete versions, sometimes even different from the original ones. This research work falls within this scope and specifically demonstrates the essential input of non-film archival documents of the time in silent film restoration processes. Those documents from now on represent the only sources attesting the original and complete form of those films. They notably allow, by comparing them with the incomplete films, both the identification of the preserved versions and the reconstruction of the narrative spine. This theoretical reflection on film restoration guiding principles [I] is then put into practice first through our examination of the restoration elements of the non-film archive collection of the American production company Triangle Film Corporation (1915-1919) preserved by the Cinémathèque française [II] then, based on the exploitation of these elements, through our contribution to the restorations of the French versions of the western The Desert Man (La Cité du désespoir, William S. Hart, 1917) and the historical drama The Despoiler (Châtiment, Reginald Barker, 1915) [III] ; two Triangle films so far presumed lost that constitute the only film elements located in the world until now

Neste trabalho, o objeto de estudo foi células Solares CdS/CdTe. Estas células usam o filme de sulfeto de cádmio (CdS) como semicondutor do tipo n e o filme de telureto de cádmio (CdTe) como semicondutor do tipo p. O recorde mundial, alcançado no laboratório, para estas células é 16,5% de eficiência. Nos Laboratórios do Departamento de Física e Química de Unesp - Ilha Solteira, este trabalho é pioneiro na fabricação de Células Solares de CdS/CdTe. Para realizar este trabalho foi necessário melhorar o sistema de deposição por spray de SnO2:F já existente, acondicionar o sistema de banho químico para deposição do filme de CdS e implementar o sistema de sublimação para depositar a camada de CdTe. Todos estes sistemas de deposição de filmes finos foram implementados no laboratório do Grupo de Desenvolvimento e Aplicação de Materiais (GDAM). A fabricação da Célula Solar CdS/CdTe consistiu na deposição sequencial sobre vidro de a) Eletrodo condutor transparente utilizando óxido de estanho dopado com Flúor (SnO2:F) pelo método de spray, com controle automático de jato; b) deposição de sulfeto de Cádmio (CdS) pelo método de banho Químico (CBD); c) deposição de Telureto de Cádmio (CdTe) pela técnica de sublimação no espaço fechado (CSS) e d) deposição do contato metálico traseiro de prata por colocação de camada liquida e posteriormente a melhora deste contato com grafite-prata. A estrutura final destas células foi: Vidro/SnO2:F/CdS/CdTe/contato. A caracterização estrutural e óptica das camadas destas células foi realizada pelas técnicas de DRX e UV-vis; os parâmetros elétricos das células foram determinados pela construção da curva I-V.

The object of this work was the study solar Cells CdS/CdTe. These cells use a cadmium sulfide film as an n-type semiconductor and a cadmium telluride film as a p- type semiconductor The world record for maximum efficiency achieved in laboratory for these cells is 16.5%. In laboratories of Departament of Physics and Chemistry of Unesp-Ilha Solteira, this work is a pioneer in the manufacture of CdS/CdTe Solar Cell. To carry out this work it was necessary to improve the existing system of Spray deposition of SnO2: F, conditioning of the system for chemical bath deposition of CdS film and manufacture the sublimation system to deposit the CdTe layer. All of these systems for the deposition of thin films were developed in the laboratory. The manufacture of CdS/CdTe solar cell consisted of sequential deposition on glass of a) transparent conductive tin oxide doped with fluorine (SnO 2:F) using automatic control system of the spray; b) deposition of cadmium sulfide (CdS) for method (CBD); c) deposition of cadmium telluride for technique in closed space sublimation (CSS) and d) the rear metallic contact of silver was deposited by placing the liquid layer and subsequent improvement of contact with graphite-silver. The final structure of cell used in this work was: glass/SnO2:F/CdS/CdTe/contact. The CdTe solar cell layer was heat treated with cadmium dichloride (CdCl2) to compare its efficiency with another cell that was not treated with cadmium dichloride. Then we investigated the performance of only putting back metal contact layer of silver of silver and silver-graphite layer, the latter was giving better results, achieving an efficiency is a well more than 5%

Filmes finos de carbono amorfo hidrogenado contendo silício e dopados com flúor foram produzudos pelos métodos de Deposição de Vapor Químico Assistido e Plasma (PECVD) e Deposição e Implantação Iônica por Imersão em Plasma (PIIID). Para PECVD foi utilizada uma pressão total de gases/vapor de 100 mTorr e inicialmente, 100W de potência de excitação. A proporção dos gases foi estudada, mantendo a concentração do hexametildisiloxano (HMDSO) em 75% e variando a proporção do argônio (Ar) e do hexafluoreto de enxofre (SF6). As porcentagens de flúor utilizadas na alimentação do plasma variaram em 0,6,9 e 12,5%. Visando maior concentração atômica de flúor na estrutura dos filmes, determinou-se a proporção de gases/vapor mais apropriada (75% HMDSO, 19% Ar e 6% SF6), e posteriormente, foi realizado um novo estudo da potência de excitação. Variando a potência entre 40 e 70 W, 50 W foi considerada como sendo a melhor condição de excitação para a descarga luminosa, considerando os efeitos causados pela corrosão relacionada ao flúor e a incorporação do elemento. Um estudo sobre as mesmas proporções foi realizada pela técnica de PIIID, com uma pressão total de 50 mTorr, potência de 50 W e pulsos negativos com magnitude de 800 V. Para este método o filme produzido com 12,5% de SF6 foi escolhido como sendo a melhor opção, tendo em vista que apresentou a maior quantidade atômica de flúor em sua estrutura. Posteriormente, a intensidade dos pulsos aplicados foi variada entre 544 e 14801 V, onde verificou-se que o aumento da intensidade dos pulsos resulta na diminuição da incorporação de flúor
Hydrogenated amorphous carbon films containing silicon and doped with fluorine were produced by two methods: Plasma Enhanced Chemical Vapor Deposition (PECVD) and Deposition (PIIID). For PECVD a total pressure of 100 mTorr was used at a excitation power of 100 W. The gas/vapor proportion was studied, keeping 75% hexamethyldisiloxane and varying the argon (Ar) and sulfur hexafluoride (SF6) ratio. The following proportions of SF6) ratio. The following proportions of SF6 were examined: 0, 6, 9 and 12.5%. Aiming for the highest atomic concentration of fluorine in film structure the best condition (75% HMDSO, 19% Ar and 6% SF6) was determined and a new study of the influence of the radiofrequency power. Considering the corrosion effects gernerated by fluorine in the plasma, variation of the applied power between 40 and 70 W, allowed the selection of 50 W as the best conditions. A study employing the same proportior PIIID was performed using 50 mTorr of total pressure, an applied power of 50 W and a pulse bias of 800 V. Considering the results of the chemical characterizations, films were produced with 12.5% of SF6 in the plasma feed. Subsequently, bias voltage was varied between 544 and 1480 V, where it was observed that the increasing the pulse bias decreased the fluorine concentration in film structure

O objetivo principal deste trabalho é elucidar quais são os mecanismos de transporte de portadores de carga presentes na interface entre SnO2 e o contato metálico, pois tal conhecimento é fundamental para a aplicação na eletrônica. Além disso, é objetivo aqui também, estudar características de transporte em SnO2 dopado com alguns íons terras-raras. As amostras de SnO2 dopadas em Eu3+ e Ce3+ utilizadas nesta pesquisa foram sintetizadas a partir do método sol-gel e os filmes finos depositados pela técnica dip-coating. Os contatos estudados foram feitos a partir dos metais In, Sn e Al, depositados via evaporação resistiva. Medidas de resistência em função da temperatura nas amostras dopadas com Eu indicaram uma variação significativa da resistividade, de até 10 vezes, quando alterado o metal do contato. Isto se deve a diferença entre a função de trabalho de cada metal, que consequentemente acarreta em variação da barreira de potencial na junção metal-semicondutor. Pela característica das curvas de corrente medida em função da tensão aplicada, observou-se que os dois mecanismos de condução elétrica dominantes na interface são a emisssão termiônica, quando em baixas temperaturas e tensões de menor intensidade, e o tunelamento através da barreira, quando em temperaturas mais altas e tensões de maior intensidade. Com base nesses resultados e na aplicação do método proposto por Rhoderick estimou-se os valores da altura da barreira de potencial na junção metal-semicondutor, em 132 meV, 162 meV e 187 meV para os metais In, Al, Sn, respectivamente. Além disso, o tratamento térmico realizado nas amostras promoveu, de modo geral, a diminuição da resistividade do dispositivo devido, provavelmente, ao estreitamento da barreira de potencial e consequente aumento da...
The main goal of this work is the verification of electrical transport mechanisms of charge carriers at the interface between SnO2 and the metallic contact, because this knowledge is fundamental for electronic applications. Besides, another goal here is to investigate transport characteristics of rare-earth doped SnO2 samples doped with Eu3+ and Ce3+ used in this research were made from the sol-gel method and the thin films were deposited via dip-coating technique. The analyzed contacts were deposited from metals In, Sn and Al, via resistive evaporation technique. Resistance as function of temperature measurements applied to Eu-doped samples indicates a significant resistivity, up to 10 times, when the contact metal is varied. This is due to the differences in the work function of each metal, leading to variation in the potential barrier at interface of the metal-semiconductor junction. The characteristics of the current-voltage curves yield two dominant electrical mechanisms at the interface: thermo-ionic emission, for low temperatures and higher applied bias, and quantum tunneling through the barrier, when the temperature is higher and so is the applied bias magnitude. Based on these results and the application of the method proposed by Rhoderick, the potential barrier height of metal-semiconductor junction values were evaluated, yielding 132 meV, 162 meV and 187 meV for the metals In, Al and Sn, respectively. Besides, generally speaking, thermal annealing promotes the resistivity decrease, probably due to the potential barrier narrowing, increasing the tunneling probability. The variation of Ce3+ concentration, from 0,1% also leads to variation in the device resistivity, but this is not related to the potential at the junction interface, instead it is related with other bulk factors, as the charge...

The proliferation of this type of film production something in-between the autoethnographies and the art films challenges the social sciences and, more specifically, the contemporary visual anthropology to understand the appearance of new audiovisual forms of social representation. The important work of Bourdieu on the social rules of photography is a starting point to debate the aesthetics of private family domain and the social rules of amateur film

Full textAbstract:
The work contained in this thesis examines how the properties of gas barrier materials may be affected by the choice of deposition technique, substrate material, and surface treatment. The performance of barriers with respect to the requirements for the optoelectronics industry was studied, along with an appraisal of the metrics used to assess barrier levels. Polyester films were coated with aluminium oxide by reactive sputter deposition in an industrial-scale research web coater. The transparency and stoichiometry of coatings was achieved by control of the reactive gas supply levels, and the deposition configuration in the web coater. Target poisoning, which leads to low deposition rates, was controlled by balancing the inert and reactive gases and by changing the reactive gas supply locations. Barrier properties of the films were found to be affected strongly by the choice of power supply. By using a method of depositing many thin layers of AIOx sequentially to build up a single layer, it was possible to extend the region of high barrier performance out to thick coatings of several hundred nanometres and thus create very high barrier materials. PEN (polyethylene naphtha late) film was used as a substrate material for all samples. It is a good candidate for use as a substrate for barrier films due to its excellent thermal, mechanical, and barrier properties. The use of surface treatments to minimise the effect of substrate surface features was examined. It was found that for coating thicknesses greater than 50 nm the surface smoothing layers did not improve barrier properties, and coated films with no smoothing layer performed better in water vapour transmission tests. Fragmentation tests showed that the barrier performance of films was greatly affected by the adhesion between the substrate and aluminium oxide coating. Various methods for measuring barrier film properties were studied in this work. The standard steady-state test for gas transmission rates was compared with the non-standardised calcium test. Organic photovoltaic (OPV) devices were encapsulated with barrier films to measure to what extent they act as a barrier to contaminants such as water vapour and oxygen. In a separate experiment, a component material of the OPV devices, poly(3-hexylthiophene) (P3HT), was used successfully in encapsulation tests where its degradation was measured using UV-vis-nIR spectrometry.

Full textAbstract:
Filmes de Langmuir e Langmuir-Blodgett (LB) foram produzidos a partir da polianilina não substituída, que se tornou processável e solúvel em clorofórmio apos ser dopada com ácidos funcionalizados. Para atingir condições otimizadas de formação e deposição dos filmes, foi realizado um estudo criterioso empregando vários ácidos funcionalizados: canfor sulfônico (CSA), dodecilbenzeno sulfônico (DBSA) e tolueno sulfônico (TSA); e também os solventes e plastificantes N-metilpirrolidinona (NMP) e m-cresol. Soluções de polianilina de alta massa molar processada com estes ácidos foram depositadas sobre subfases aquosas ácidas (pH = 2), formando os chamados filmes monomoleculares de Langmuir. Através de um estudo dos parâmetros que influenciam a formação dos filmes de Langmuir conseguimos obter monocamadas estáveis. Desta forma os filmes puderam ser transferidos para substratos sólidos (vidro bk7), usando a técnica de Langmuir-Blodgett. Os filmes LB produzidos são do tipo Z, ou seja, a deposição só é bem sucedida na retirada do substrato, o que significa que mesmo no filme de Langmuir alguns grupos hidrofílicos se encontravam na interface filme/ar. Os filmes LB foram caracterizados por espectroscopia de UV-vis., medidas de condutividade usando o método de quatro pontas, voltametria cíclica e medidas do potencial de superfície. Os filmes LB apresentam propriedades óticas e eletroativas semelhantes as dos filmes de polianilina fabricados por centrifugação. A absorbância da banda polarônica aumenta linearmente com o número de camadas depositadas, o que demonstra que cada camada contribui com a mesma quantidade de material para o filme. A condutividade dos filmes e da ordem de 10-4 S/cm, inferior aos valores medidos para filmes obtidos por centrifugação de soluções de polianilina com CSA e DBSA, mas é maior do que a de alguns outros filmes LB de polianilina relatados na literaturaLangmuir-Blodgett (LB) films were fabricated from parent polyaniline (PANI), which was made soluble in chloroform by being doped with functionalized acids. Optimized conditions for LB film deposition were only reached after a systematic processability study in which use was made of camphor sulfonic acid (CSA), dodecylbenzene sulfonic acid (DBSA), toluene sulfonic acid (TSA) and of N-methyl pyrrolidinone (NMP) and m-cresol as plasticizers. Solutions of high molecular weight PANI were spread on acidic, aqueous subphases (pH = 2), thus forming the so-called Langmuir monolayer. These monolayer were transferred onto solid substrates (bk7 glass) in the form of Z-type films, i.e. deposition was successful only in the upstrokes. This means that hydrophilic groups must protrude from the water surface in the Langmuir film. The LB films were characterized using UV-vis spectroscopy, cyclic voltammeter, surface potential and conductivity measurements. The optical and electroactive properties of the deposited LB films were essentially the same as those obtained with spin-coated PANI films. The absorbance of the polaronic peak increases linearly with the number of deposited layers, demonstrating that each layer contributed an equal amount of material to the LB film. The films conductivity was of the order of 10-4 S/cm, which is below the values of spin coated PANI films processed with CSA or DBSA, but higher than some published values for LB films from polyaniline

The aim of master thesis was to study structural and transport properties of PVA films modified with method of semi-IPN with suitable polyectrolytes and plasticizers. The first important step was optimalization of PVA films preparation, when time of heating was set at 90 °C for 1 hour. Drying was set at 50 °C for 24 hours. Molecular weight of PVA was chosen 85–124 kDa in concentration 10 wt.%. For preparation of PVA-based semi-IPN thin films polyelectrolytes (polyglutamic acid, DEAE-dextran hydrochloride) and plasticizer (glycerol) were selected. Basic characterization of prepared materials was performed with FTIR, TGA, SEM and specific surface analysis. The difference between modified PVA films was in the chargé of individual functional groups carried by used polyelectrolytes. Surfaces of all the PVA films were smooth without visible defects. Transport properties were characterized with the method of horizontal diffusion cell with methylen blue used as a probe. Diffusion coefficients of methylen blue through PVA films were determined. It was found, that the fastest pass was throw PVA film without additives. The slowest diffusion was observed through PVA/DEAE-dextran film, because of the same charge of the film with a probe. PVA/PGA reacted with methylen blue to form a complex. Plasticizer effect on the diffusion was only minor; it caused a slight decrease of diffusion coefficient. These films were easier to handle.

Martin Scorsese's films, GOODFELLAS and CASINO, and Quentin Tarantino's RESERVOIR DOGS and PULP FICTION are examined to determine if the crime film of the 1990s has become increasingly more in the style of film noir. The differences and similarities between the two crime films each director has either written or co-written in the 1990s are delineated to demonstrate this trend. Other crime films of the latter 1990s (SEVEN, THE USUAL SUSPECTS, and MULHOLLAND FALLS) are also examined to aid in defining the latest incarnation of the crime film as "Noir Modernist," a term that is demonstrated to be a more accurate description for the current crime films than B.

O ácido politiofeno acético (PTAA) é um derivado do politiofeno bastante versátil. Sua solubilidade em alguns solventes orgânicos e em soluções básicas aquosas lhe confere extensa processabilidade na forma de filmes finos, característica importante para dispositivos e sensores. Neste trabalho, investigou-se a formação de filmes de PTAA com as técnicas de automontagem e Langmuir-Blodgett (LB). Os filmes automontados foram preparados com dois policátions, hidrocloreto de poli-alilamina (PAH) e cloreto de poli-dialildimetilamônio (PDAC). O crescimento dos filmes depende do pH das soluções e do tipo de policátion, sugerindo dependência do mecanismo de crescimento com as interações específicas polímeropolímero. A conformação do PTAA em filme tem correlação com sua conformação em solução, apontando para um efeito de memória. Por outro lado, a energia de superfície destes filmes não sofre influência da arquitetura nem dessas diferenças conformacionais. Ou seja, embora o volume do filme possa ser distinto, as superfícies possuem propriedades semelhantes. A morfologia dos filmes foi caracterizada a partir de imagens de AFM utilizando conceitos de geometria fractal e estatística. A dimensão fractal dos filmes é semelhante, indicando o mesmo processo de crescimento dos filmes, independentemente das condições da deposição. Os filmes obtidos em pH ácido tinham tamanho de grão e comprimentos de correlação maiores, sugerindo a deposição de cadeias mais enoveladas. Foi possível fabricar filmes autossustentados sem degradação aparente do material a partir de filmes automontados de PAH/PTAA, entrecruzando termicamente os grupos ácido carboxílico e amina. Este é o primeiro relato de filmes deste tipo com derivado do politiofeno. Os filmes LB de PTAA foram obtidos sem adjuvantes, mas as condições de deposição precisam ser aprimoradas. Para explorar a elevada afinidade química entre compostos contendo enxofre e metais pesados, filmes foram utilizados para detecção espectroscópica e eletroquímica. Espectros de fotoluminescência e UV-Vis demonstraram que os metais interagem apenas com os estados excitados resultando na supressão da fluorescência; no entanto, sem especificidade e apenas para longos períodos de exposição. Espectros de FTIR mostraram a presença dos sais na matriz dos filmes. Por sua vez, voltametrias cíclicas permitiram detectar Pb+2 e Hg+2, mas a irreversibilidade dos processos eletroquímicos, causando alargamento dos picos de oxirredução, inviabiliza a detecção simultânea.Polythiophene acetic acid (PTAA) is a versatile polythiophene derivative. Its solubility in some organic solvents and in basic aqueous solutions makes it attractive for processing thin films, an important feature for the fabrication of devices and sensors. In this thesis, we investigate the formation of PTAA films using the layer-by-layer (LbL) and the Langmuir- Blodgett (LB) techniques. The LbL films were prepared with poly(allylamine hydrochloride) (PAH) and poly(diallydimethylammonium chloride) (PDAC), with film growth depending on the pH of the solutions and type of polycation, thus indicating that the growth mechanism depends on polymer-polymer interactions. The conformation of the PTAA molecules in solid state was correlated with that in solution, in a kind of memory effect. The surface energy of the films was not affected by the film architecture or different conformations. The film morphology was characterized with AFM images using concepts of fractal geometry and statistics. The fractal dimension was similar for all films, and therefore the overall growth obeys the same process regardless of the deposition conditions. Nevertheless, films obtained at acidic pH exhibited larger grain size and correlation lengths than those produced at basic pHs, suggesting deposition of more coiled chains. It was also possible to fabricate selfsustained films without apparent PTAA degradation from the PAH/PTAA LbL films, upon thermal crosslinking of carboxylic acid and amine groups. This is the first report of such films with a polythiophene derivative. LB films of PTAA were obtained without co-spreading materials, but the deposition conditions need to be optimized. To explore the high chemical affinity between PTAA and compounds containing sulfur and heavy metals, some films were used for spectroscopic and electrochemical detection. The UV-Vis and photoluminescence spectra indicated that the metals affect only the excited states, leading to fluorescence quenching after long exposure times and without specificity for the metals. The FTIR spectra pointed to salts in the films. Pb+2 and Hg+2 ions could be detected using cyclic voltammetry, but their simultaneous detection was hampered by the irreversibility of the electrochemical processes which caused broadening of the oxi-reduction peaks.

Full textAbstract:
Filmes de Langmuir e Langmuir-Blodgett (LB) foram fabricados a partir de ligninas de bagaço de cana-de-açúcar e da Pinus caribaea hondurensis, extraídas via processo organossolve. Obteve-se nove tipos de lignina de pinus, sendo que cada uma foi extraída com um sol vente diferente, e seis tipos de lignina de cana, as quais passaram por um fracionamento, diminuindo sua polidispersividade. Os filmes de Langmuir foram fabricados sobre subfases de água ultrapura e caracterizados por medidas de pressão e potencial de superfície. Em todos os casos constatou-se a formação de agregados não monomoleculares quando o filme é comprimido além do ponto de colapso, o que é notado pela grande histerese na isoterma pressãoárea. Para ligninas de baixa massa molecular, estruturas estáveis não monomoleculares são formadas antes do colapso. No caso das ligninas menos polidispersas (cana), a massa molecular aumenta linearmente com a área molecular média da lignina. Monocamadas das ligninas de pinus e cana puderam ser transferidas para substratos de vidro, constituindo-se nos primeiros filmes de Langmuir-Blodgett destes materiais. Através do monitoramento da velocidade de imersão e retirada do substrato da subfase pode-se fabricar diferentes tipos de filmes LB, os quais podem ser do tipo Y com a deposição ocorrendo na imersão e retirada do substrato e também dos tipos X e Z se a deposição ocorre preferencialmente na imersão ou retirada do substrato, respectivamente. Os filmes LB foram caracterizados por medidas do potencial de superfície e elipsometria. O potencial de superfície para os filmes de pinus são positivos, enquanto que para os filmes de cana são negativos. Esta inversão de sinal foi surpreendente, pois para as monocamadas os valores de potencial são sempre positivos, tanto para as ligninas de cana como para as de pinus, embora sejam maiores no caso da pinus. A razão para esta inversão é uma contribuição negativa da interface filme/substrato que suplanta a contribuição positiva dos dipolos do filme de lignina de cana. Os dados elipsométricos revelaram que a lignina apresenta um arranjo tridimensional, com muitos espaços vazios e uma espessura em torno de 60 \'angstrom\' por camada.Langmuir monolayers and Langmuir-Blodgett (LB) films were fabricated from lignins extracted from Pinus caribaea hondurensis and sugar cane bagasse using the organosolv processo Nine types of pinus lignins were obtained by employing different solvents. The lignins of sugar cane bagasse were extracted using only one solvent but the material was fractioned into six fractions according to the molecular sizes. The resulting lignins were then less polydisperse than the pinus lignins. Langmuir monolayers were spread onto ultrapure water subphases and characterized by surface pressure and surface potential measurements. In all cases, non-monomolecular aggregates are formed when the monolayer is compressed beyond the collapse pressure, which is denoted by large hysteresis in pressurearea isotherms. For the low molecular weight lignins, stable multilayer structures are formed even before collapse. In the less polydisperse bagasse lignins, the average area per molecule increases linearly with the molecular weight. Monolayers from both pinus and bagasse lignins could be transferred onto glass substrates, thus forming the first ever reported Langmuir-Blodgett (LB) films of these materials. By controlling the dipping speed one can build-up different types of LB film which can be y-type with deposition occurring in both upstrokes and downstrokes and also Z or x-type if transfer occurs only in the upstrokes or downstrokes, respectively. The deposited LB films were characterized by surface potential and ellipsometric measurements. The surface potential of pinus films is positive whereas that of bagasse lignins is negative. This sign inversion was surprising since the monolayer surface potentials were always positive for all materials, even though they were higher for the Pinus lignins. The reason for the inversion is the negative contribution of the film/substrate interface which surpass the small, positive contribution from the dipole moments in the bagasse lignins. The ellipsometric data showed that the lignin molecules assume a three-dimensional arrangement, even within a single layer. The LB film appears to be a highly porous structure, with a thickness of 60 Á per layer.

Full textAbstract:
The rapid progress of n-type metal oxide thin film transistors (TFTs) has motivated research on p-type metal oxide TFTs in order to realise metal oxide-based CMOS circuits which enable low power consumption large-area electronics. Cuprous oxide (Cu2O) has previously been proposed as a suitable active layer for p-type metal oxide TFTs. The two most significant challenges for achieving good quality Cu2O TFTs are to overcome the low field-effect mobility and an unacceptably high off-state current that are a feature of devices that have been reported to date. This dissertation focuses on improving the carrier mobility, and identifying the main origins of the low field-effect mobility and high off-state current in Cu2O TFTs. This work has three major findings. The first major outcome is a demonstration that vacuum annealing can be used to improve the carrier mobility in Cu2O without phase conversion, such as oxidation (CuO) or oxide reduction (Cu). In order to allow an in-depth discussion on the main origins of the very low carrier mobility in as-deposited films and the mobility enhancement by annealing, a quantitative analysis of the relative dominance of the main conduction mechanisms (i.e. trap-limited and grain-boundary-limited conduction) is performed. This shows that the low carrier mobility of as-deposited Cu2O is due to significant grain-boundary-limited conduction. In contrast, after annealing, grain-boundary-limited conduction becomes insignificant due to a considerable reduction in the energy barrier height at grain boundaries, and therefore trap-limited conduction dominates. A further mobility improvement by an increase in annealing temperature is explained by a reduction in the effect of trap-limited conduction resulting from a decrease in tail state density. The second major outcome of this work is the observation that grain orientation ([111] or [100] direction) of sputter-deposited Cu2O can be varied by control of the incident ion-to-Cu flux ratio. Using this technique, a systematic investigation on the effect of grain orientation on carrier mobility in Cu2O thin films is presented, which shows that the [100] Cu2O grain orientation is more favourable for realising a high carrier mobility. In the third and final outcome of this thesis, the temperature dependence of the drain current as a function of gate voltage along with the C-V characteristics reveals that minority carriers (electrons) cause the high off-state current in Cu2O TFTs. In addition, it is observed that an abrupt lowering of the activation energy and pinning of the Fermi energy occur in the off-state, which is attributed to subgap states at 0.38 eV below the conduction band minimum. These findings provide readers with the understanding of the main origins of the low carrier mobility and high off-state current in Cu2O TFTs, and the future research direction for resolving these problems.

Full textAbstract:
The commentary addresses the works in the Research Portfolio (2010-2016) which consists of three films and one multi-media installation. These films are experimental but look very different from my previous work. This reflects my decision to address figuration and realist representation in order to expand and develop my experimental film language. The works are collective and individual portraits of women in monastic life, and one is a portrait of a young girl in a Catholic iconography. In these new works I find out what happens when you insert direct works about religion into an art space that is not expecting them and has no context ready for them. My aim is to see how that changes and tests the binaries of religion/art, traditional/experimental. The commentary investigates the works through a Catholic framing/perspective; close reading as a method of viewing the work, and a feminist analysis that provides gendered readings of the works. These three come together to open a space of reflection and a critical perspective on the films. The commentary shows how the works open a space for a religious subject to emerge: one not hitherto represented in the context of experimental film.

The goal of this dissertation has been to develop techniques in order to use Brillouin spectroscopy as a tool for studying the elastic properties of thin films on a scale of ≃100 Å. In order to develop that capability we have built a tandem multi-pass Fabry-Perot interferometer, and that interferometer was used to study the elastic properties of Langmuir-Blodgett films. These films were chosen because they can be deposited one molecular layer at a time. As a result of these investigations we have measured the density and elastic constants of the Langmuir-Blodgett film cadmium arachidate. Samples of cadmium arachidate were prepared on molybdenum and BK-7 glass substrates. Data were accumulated for a range of thicknesses and for different scattering geometries. These data will be used to argue that guided acoustic waves were observed in a highly anisotropic film. The observed guided acoustic waves will be identified as a Rayleigh wave and a tight band of Sezawa modes. No Love modes were detected in these experiments; however, evidence for reorientational modes typical of anisotropic liquids was detected. The dispersion of the Rayleigh wave as a function of thickness together with thick film scattering data were used to estimate the elastic constants in cadmium arachidate. In particular the shear elastic constant c₄₄ was found to be a small value: c₄₄ < 4.0x10⁸ N/m². The remaining elastic constants were estimated, assuming hexagonal film symmetry, to be c₆₆ < 4.5x10⁹ N/m², C₁₁ ≃ 1.1x10¹⁰ N/m², c₃₃ ≃ 2.1x10¹⁰ N/m², c₁₃ ≃ 1.0x10¹⁰ N/m², and c₁₂ > 3.x10¹⁰ N/m². It is interesting to note that the acoustical behavior of cadmium arachidate is quite similar to the smectic phase liquid crystals (c₄₄ = 0).

O termo multiferróico (ou ferroeletromagnético) é utilizado para descrever materiais que apresentam duas ou mais das propriedades ferróicas primárias (ferroeletricidade, ferromagnetismo ou ferroelasticidade) ocorrendo na mesma fase. Tais materiais são conhecidos desde a década de 60, entretanto, sua potencial aplicação no armazenamento de informações tem despertado grande interesse da comunidade cientifica nos últimos anos. O BiFeO3 tem recebido especial atenção devido à coexistência de propriedades ferroelétricas e magnéticas. Devido a este acoplamento novas possibilidades de armazenamento de dados, em elementos de memória ferroelétrica, podem ser criadas de forma não destrutiva. Este material proporciona uma alternativa para substituição de compostos ferroelétricos e piezelétricos livres de chumbo, sendo ambientalmente favorável. A ferrita de bismuto é um dos candidatos, por ser um material ferroelétrico com temperatura de Curie (TC) relativamente alta 1000 K e por exibir comportamento antiferromagnético com temperatura de Neel (TN) 643 K. Estas características fazem com que este material apresente um grande valor de polarização espontânea Ps.

This kind of materials are known since the 60's, however, its potential application in the information store has been much interest from the scientific community in recent years. The BiFeO3 has received special attention due to the coexistence of ferroelectric and magnetic properties. Because of this coupling new possibilities for data storage in ferroelectric memory elements can be created in a non-destructive. This material provides an alternative replacement for ferroelectric and piezoelectric compounds of lead-free and environmentally excellent. The bismuth ferrite is a candidate for being a ferroelectric material with high Curie temperature (Tc) 1000 K and exhibit antiferromagnetic behavior with Neel temperature (TN).

Abstract: The object of this work was the study solar Cells CdS/CdTe. These cells use a cadmium sulfide film as an n-type semiconductor and a cadmium telluride film as a p- type semiconductor The world record for maximum efficiency achieved in laboratory for these cells is 16.5%. In laboratories of Departament of Physics and Chemistry of Unesp-Ilha Solteira, this work is a pioneer in the manufacture of CdS/CdTe Solar Cell. To carry out this work it was necessary to improve the existing system of Spray deposition of SnO2: F, conditioning of the system for chemical bath deposition of CdS film and manufacture the sublimation system to deposit the CdTe layer. All of these systems for the deposition of thin films were developed in the laboratory. The manufacture of CdS/CdTe solar cell consisted of sequential deposition on glass of a) transparent conductive tin oxide doped with fluorine (SnO 2:F) using automatic control system of the spray; b) deposition of cadmium sulfide (CdS) for method (CBD); c) deposition of cadmium telluride for technique in closed space sublimation (CSS) and d) the rear metallic contact of silver was deposited by placing the liquid layer and subsequent improvement of contact with graphite-silver. The final structure of cell used in this work was: glass/SnO2:F/CdS/CdTe/contact. The CdTe solar cell layer was heat treated with cadmium dichloride (CdCl2) to compare its efficiency with another cell that was not treated with cadmium dichloride. Then we investigated the performance of only putting back metal contact layer of silver of silver and silver-graphite layer, the latter was giving better results, achieving an efficiency is a well more than 5%

Resumo: Filmes finos de carbono amorfo hidrogenado contendo silício e dopados com flúor foram produzudos pelos métodos de Deposição de Vapor Químico Assistido e Plasma (PECVD) e Deposição e Implantação Iônica por Imersão em Plasma (PIIID). Para PECVD foi utilizada uma pressão total de gases/vapor de 100 mTorr e inicialmente, 100W de potência de excitação. A proporção dos gases foi estudada, mantendo a concentração do hexametildisiloxano (HMDSO) em 75% e variando a proporção do argônio (Ar) e do hexafluoreto de enxofre (SF6). As porcentagens de flúor utilizadas na alimentação do plasma variaram em 0,6,9 e 12,5%. Visando maior concentração atômica de flúor na estrutura dos filmes, determinou-se a proporção de gases/vapor mais apropriada (75% HMDSO, 19% Ar e 6% SF6), e posteriormente, foi realizado um novo estudo da potência de excitação. Variando a potência entre 40 e 70 W, 50 W foi considerada como sendo a melhor condição de excitação para a descarga luminosa, considerando os efeitos causados pela corrosão relacionada ao flúor e a incorporação do elemento. Um estudo sobre as mesmas proporções foi realizada pela técnica de PIIID, com uma pressão total de 50 mTorr, potência de 50 W e pulsos negativos com magnitude de 800 V. Para este método o filme produzido com 12,5% de SF6 foi escolhido como sendo a melhor opção, tendo em vista que apresentou a maior quantidade atômica de flúor em sua estrutura. Posteriormente, a intensidade dos pulsos aplicados foi variada entre 544 e 14801 V, onde verificou-se que o aumento da intensidade dos pulsos resulta na diminuição da incorporação de flúor
Abstract: Hydrogenated amorphous carbon films containing silicon and doped with fluorine were produced by two methods: Plasma Enhanced Chemical Vapor Deposition (PECVD) and Deposition (PIIID). For PECVD a total pressure of 100 mTorr was used at a excitation power of 100 W. The gas/vapor proportion was studied, keeping 75% hexamethyldisiloxane and varying the argon (Ar) and sulfur hexafluoride (SF6) ratio. The following proportions of SF6) ratio. The following proportions of SF6 were examined: 0, 6, 9 and 12.5%. Aiming for the highest atomic concentration of fluorine in film structure the best condition (75% HMDSO, 19% Ar and 6% SF6) was determined and a new study of the influence of the radiofrequency power. Considering the corrosion effects gernerated by fluorine in the plasma, variation of the applied power between 40 and 70 W, allowed the selection of 50 W as the best conditions. A study employing the same proportior PIIID was performed using 50 mTorr of total pressure, an applied power of 50 W and a pulse bias of 800 V. Considering the results of the chemical characterizations, films were produced with 12.5% of SF6 in the plasma feed. Subsequently, bias voltage was varied between 544 and 1480 V, where it was observed that the increasing the pulse bias decreased the fluorine concentration in film structure

Resumo: O termo multiferróico (ou ferroeletromagnético) é utilizado para descrever materiais que apresentam duas ou mais das propriedades ferróicas primárias (ferroeletricidade, ferromagnetismo ou ferroelasticidade) ocorrendo na mesma fase. Tais materiais são conhecidos desde a década de 60, entretanto, sua potencial aplicação no armazenamento de informações tem despertado grande interesse da comunidade cientifica nos últimos anos. O BiFeO3 tem recebido especial atenção devido à coexistência de propriedades ferroelétricas e magnéticas. Devido a este acoplamento novas possibilidades de armazenamento de dados, em elementos de memória ferroelétrica, podem ser criadas de forma não destrutiva. Este material proporciona uma alternativa para substituição de compostos ferroelétricos e piezelétricos livres de chumbo, sendo ambientalmente favorável. A ferrita de bismuto é um dos candidatos, por ser um material ferroelétrico com temperatura de Curie (TC) relativamente alta 1000 K e por exibir comportamento antiferromagnético com temperatura de Neel (TN) 643 K. Estas características fazem com que este material apresente um grande valor de polarização espontânea Ps. Nessa linha de estudo, a pesquisa buscou obter filmes finos e nanoestruturas de BiFeO3 puro e dopado com Sm. Os filmes finos foram depositados sobre substrato de Pt/TiO2/SiO2/Si utilizando spin coating e solução precursora preparada pelo método dos precursores poliméricos, tratados a 500oC por 2h. Os difratogramas de raios X (DRX) e a microscopia de força atômica (AFM) mostraram que os filmes não apresentam fase secundária, a microestrutura tem tamanho de grão homogêneo e distribuição uniforme na superfície.

Abstract: The term multiferroic (or ferroeletromagnetic) is used to describe materials that have two or more properties ferroic primary (ferroelectricity, ferromagnetism or ferroelasticity) occurring at the same phase. This kind of materials are known since the 60's, however, its potential application in the information store has been much interest from the scientific community in recent years. The BiFeO3 has received special attention due to the coexistence of ferroelectric and magnetic properties. Because of this coupling new possibilities for data storage in ferroelectric memory elements can be created in a non-destructive. This material provides an alternative replacement for ferroelectric and piezoelectric compounds of lead-free and environmentally excellent. The bismuth ferrite is a candidate for being a ferroelectric material with high Curie temperature (Tc) 1000 K and exhibit antiferromagnetic behavior with Neel temperature (TN). These characteristics make this material presents a large value of spontaneous polarization Ps. In this line of study, the research sought to obtain thin films and nanostructures BiFeO3 pure and doped with Sm. The thin films were deposited on Pt/TiO2/SiO2/Si substrates using spin coating and precursor solution prepared by the polymeric precursors treated at 500oC for 2 hours. The X-ray diffraction (XRD) and atomic force microscopy (AFM) showed that the films do not exhibit secondary phase, the microstructure is homogeneous grain size and uniform distribution on the surface. The hysteresis of films BFO pure showed values of (Pr) 2.93 C/cm2 and coercive field (Ec) of 7.4 kV / cm for an applied electric field of 15 kV / cm. The doped with samarium showed an increase in the value of remanent polarization with increasing dopant concentration. The BFO nanostructures and doped with...

Resumo: O objetivo principal deste trabalho é elucidar quais são os mecanismos de transporte de portadores de carga presentes na interface entre SnO2 e o contato metálico, pois tal conhecimento é fundamental para a aplicação na eletrônica. Além disso, é objetivo aqui também, estudar características de transporte em SnO2 dopado com alguns íons terras-raras. As amostras de SnO2 dopadas em Eu3+ e Ce3+ utilizadas nesta pesquisa foram sintetizadas a partir do método sol-gel e os filmes finos depositados pela técnica "dip-coating". Os contatos estudados foram feitos a partir dos metais In, Sn e Al, depositados via evaporação resistiva. Medidas de resistência em função da temperatura nas amostras dopadas com Eu indicaram uma variação significativa da resistividade, de até 10 vezes, quando alterado o metal do contato. Isto se deve a diferença entre a função de trabalho de cada metal, que consequentemente acarreta em variação da barreira de potencial na junção metal-semicondutor. Pela característica das curvas de corrente medida em função da tensão aplicada, observou-se que os dois mecanismos de condução elétrica dominantes na interface são a emisssão termiônica, quando em baixas temperaturas e tensões de menor intensidade, e o tunelamento através da barreira, quando em temperaturas mais altas e tensões de maior intensidade. Com base nesses resultados e na aplicação do método proposto por Rhoderick estimou-se os valores da altura da barreira de potencial na junção metal-semicondutor, em 132 meV, 162 meV e 187 meV para os metais In, Al, Sn, respectivamente. Além disso, o tratamento térmico realizado nas amostras promoveu, de modo geral, a diminuição da resistividade do dispositivo devido, provavelmente, ao estreitamento da barreira de potencial e consequente aumento da...

Abstract: The main goal of this work is the verification of electrical transport mechanisms of charge carriers at the interface between SnO2 and the metallic contact, because this knowledge is fundamental for electronic applications. Besides, another goal here is to investigate transport characteristics of rare-earth doped SnO2 samples doped with Eu3+ and Ce3+ used in this research were made from the sol-gel method and the thin films were deposited via dip-coating technique. The analyzed contacts were deposited from metals In, Sn and Al, via resistive evaporation technique. Resistance as function of temperature measurements applied to Eu-doped samples indicates a significant resistivity, up to 10 times, when the contact metal is varied. This is due to the differences in the work function of each metal, leading to variation in the potential barrier at interface of the metal-semiconductor junction. The characteristics of the current-voltage curves yield two dominant electrical mechanisms at the interface: thermo-ionic emission, for low temperatures and higher applied bias, and quantum tunneling through the barrier, when the temperature is higher and so is the applied bias magnitude. Based on these results and the application of the method proposed by Rhoderick, the potential barrier height of metal-semiconductor junction values were evaluated, yielding 132 meV, 162 meV and 187 meV for the metals In, Al and Sn, respectively. Besides, generally speaking, thermal annealing promotes the resistivity decrease, probably due to the potential barrier narrowing, increasing the tunneling probability. The variation of Ce3+ concentration, from 0,1% also leads to variation in the device resistivity, but this is not related to the potential at the junction interface, instead it is related with other bulk factors, as the charge...

Full textAbstract:
This thesis studies American studio feature films whose narratives are inspired by the Bible’s Book of Revelation. I identify these films as belonging to a subgenre of supernatural horror I have named ‘eschato-horror’. American eschato-horror films reflect Christian eschatology and its violent visions of cosmic war between divine and satanic forces. While supernatural horror films exploit our fear of death and evil, American Eschato-horror ups the cultural stakes through its representations of pseudo Catholic and other Christian ritual, scripture, and iconography in its mission to frighten the viewer. Other national cinemas produce their own eschatology inspired films, but the American rendering of the genre as produced and exported by major Hollywood studios and distribution companies dominates screens world-wide.
In order to better understand the cultural importance and usefulness of American Eschato-horror for film fans as well as self-identifying American Christian audiences, this thesis will study three examples of the genre, Constantine (Lawrence, 2005), Knowing (Proyas, 2009) and Legion (Stewart, 2010), all of which were produced by or for major American motion picture companies and distributors. Demonstrating that the version of eschatology found in their narratives reflects an identifiable American Protestant Christianity will be accomplished though an historical overview tracing Christianity from its roots as the marginalized, millennially-inspired “Jesus Cult,” to its evolution into one of the most powerful forces shaping American history and culture. The narrative elements associated with eschato-horror (monstrous women, self-sacrificing heroes, faithless priests, etc.), will be seen to be as much an expression of our collective fear of death and evil – forces James Carse associates with religion – as the Biblical illiteracy and confused understanding of Christianity identified by Stephen Prothero and Richard T. Hughes so central to contemporary America’s view of itself as being “a Christian Nation.” The reception of American Eschato-horror films as seen on film fan and Christian websites, especially in light of discourse similarities identified in film fan cults and religious cults, will be considered through the work of Matt Hills, Ernest Mathijs, Jamie Sexton and Jeff Hunter.Arts, Faculty of

Mestrado em Engenharia Alimentar - Instituto Superior de AgronomiaAn experimental design to obtain films from chitosan was elaborated with the incorporation of crosslinker (ethylene glycol diglycidylether), nisin and glycerol. The independent variables were chitosan concentration (0,7-2,3%), acetic acid concentration (0,3-3%) and molar ratio of crosslinking/polymer (0-4). Although there was a significant effect of the single independent variables on the films properties determined throughout the study, no interaction between them was noticed. Chitosan and gelatin blend films were also produced with different proportions, as well as bi-layered films. The rheology of the filmogenic solutions showed that crosslinking only takes place during film formation, and not when the crosslinking agent was added to the solution. We observed that the value of the storage and loss modulus as well as the viscosity, increased with concentration of chitosan. The films obtained were very hydrophilic. Even though the values were relatively high, there was less water absorption capacity and solubility in water and in acid, for central values of molar ratio crosslinker/polymer. Regarding the mechanical properties of the films, the tensile strength was positively affected by the decrease of pH and the increase of molar ratio crosslinker/polymer, whereas, the elongation at rupture was only affected by the chitosan concentration. As expected, the higher the proportion of chitosan on blend and bi-layer films the closer they resembled the straight for waned chitosan films in what mechanical behavior is concerned

Organic materials exhibiting second-order non-linear optical (NLO) properties are a key to the development of advanced electro-optic (EO) modulators used in fiber-optic communications system. This work addresses the fabrication and characterization of organic materials with NLO properties using a self-assembly approach by alternately dipping a charged substrate into positively and negatively charged polymers to build up layer-by-layer (LbL) films.
The effect of solution pH on the formation of LbL films fabricated using the polycation poly(allylamine hydrochloride) (PAH) and the polyanion poly{1-[p-(3–-carboxy-4–-hydroxyphenylazo)benzenesulfonamido]-1,2-ethandiyl} (PCBS) was studied using a quartz crystal microbalance with dissipation (QCM-D) monitoring, ellipsometry, absorbance, and second harmonic generation (SHG) measurements. PCBS has an azo-benzene chromophore side group that, when sufficiently oriented, results in measurable SHG. Films of PAH/PCBS fabricated at neutral pH where both PAH and PCBS are highly charged led to thin bilayers, ~1 nm, with a 1:1 molar ratio of PCBS:PAH. This molar ratio was found to be important for long-range polar ordering of PCBS in these films. Increasing the rate of convection was found to reduce the time required for complete adsorption of the polyion. This can have a significant impact on fabrication of films with high bilayer numbers.
A variation of the above technique, which involves adsorbing one of the constituents electrostatically and another covalently, was studied using PAH and a reactive dye, Procion Brown (PB), which has a significantly higher hyperpolarizability than PCBS. It was found that a high pH, ~10.5, was important for achieving covalent attachment of the PB to the underlying PAH films. This resulted in much higher SHG intensities compared to when PB was deposited pH at 8.5-9.5 where the attachment of PB was due to a combination of electrostatic and covalent interactions. QCM-D results for PAH/PB films revealed the presence of a high percentage of unreacted amine groups in the underlying PAH film. A rate constant value for PB attachment step to the underlying PAH was also calculated.
To enhance the SHG intensity of these films, silver nanoprisms were synthesized and deposited onto films using physisorption. An enhancement in the SHG intensity was observed for both PAH/PCBS and PAH/PB films.Ph. D.

Full textAbstract:
The growth of Co (0001) films and Cr2O3 (0001)/Co (0001) has been investigated using surface analysis methods. Such films are of potential importance for a variety of spintronics applications. Co films were directly deposited on commercial Al2O3 (0001) substrates by magnetron sputter deposition or by molecular beam epitaxy (MBE), with thicknesses of ~1000Å or 30Å, respectively. Low Energy Electron Diffraction (LEED) shows hexagonal (1x1) pattern for expected epitaxial films grown at 800 K to ensure the hexagonally close-packed structure. X-ray photoemission spectroscopy (XPS) indicates the metallic cobalt binding energy for Co (2p3/2) peak, which is at 778.1eV. Atomic force microscopy (AFM) indicates the root mean square (rms) roughness of Co films has been dramatically reduced from 10 nm to 0.6 nm by optimization of experiment parameters, especially Ar pressure during plasma deposition. Ultrathin Cr2O3 films (10 to 25 Å) have been successfully fabricated on 1000Å Co (0001) films by MBE. LEED data indicate Cr2O3 has C6v symmetry and bifurcated spots from Co to Cr2O3 with Cr2O3 thickness less than 6 Å. XPS indicates the binding energy of Cr 2p(3/2) is at 576.6eV which is metallic oxide peak. XPS also shows the growth of Cr2O3 on Co (0001) form a thin Cobalt oxide interface, which is stable after exposure to ambient and 1000K UHV anneal.

After experimental beginnings in the 1970s, a commercial push in the 1980s, and an underground existence in the 1990s, from 2000 to 2007 contemporary Australian horror production has experienced a period of strong growth and relative commercial success unequalled throughout the past three decades of Australian film history. This study explores the rise of contemporary Australian horror production: emerging production and distribution models; the films produced; and the industrial, market and technological forces driving production. Australian horror production is a vibrant production sector comprising mainstream and underground spheres of production. Mainstream horror production is an independent, internationally oriented production sector on the margins of the Australian film industry producing titles such as Wolf Creek (2005) and Rogue (2007), while underground production is a fan-based, indie filmmaking subculture, producing credit-card films such as I know How Many Runs You Scored Last Summer (2006) and The Killbillies (2002). Overlap between these spheres of production, results in ‘high-end indie’ films such as Undead (2003) and Gabriel (2007) emerging from the underground but crossing over into the mainstream. Contemporary horror production has been driven by numerous forces, including a strong worldwide market demand for horror films and the increasing international integration of the Australian film industry; the lowering of production barriers with the rise of digital video; the growth of niche markets and online distribution models; an inflow of international finance; and the rise of international partnerships. In light of this study, a ‘national cinema’ as an approach to cinema studies needs reconsideration – real growth is occurring across national boundaries due to globalisation and at the level of genre production rather than within national boundaries through pure cultural production. Australian cinema studies – tending to marginalise genre films – needs to be more aware of genre production. Global forces and emerging distribution models, among others, are challenging the ‘narrowness’ of cultural policy in Australia – mandating a particular film culture, circumscribing certain notions of value and limiting the variety of films produced domestically.
