Повний текст джерелаThe aim of this work is to implement new properties to a paper based material via the use of functional nanocelluloses. Nanocelluloses are nanoparticles extracted from wood and distinguished in two categories: Cellulose Nanofibrils (CNFs) and Cellulose Nanocrystals (CNCs). This work has only been carried out with CNFs. The chemical reactivity of CNFs was used to functionalize them with organotrialkoxysilanes. The entangled network and highly viscous suspension of CNFs was also used to synthesize silsesquioxane particles with limited size to impart (super)hydrophobic and antimicrobial properties. Knowledge obtained through the study of model CNFs films was then applied to paper based material coating. The functional CNFs were evaluated for its use in an antimicrobial, anti-adherent, greaseproof or superhydrophobic paper surface

Повний текст джерелаFunctionalized nanoparticles continue to attract interest in biomedical applications and bioassays and have become a key focus in nanobiotechnology research. One of the primal focuses of the research work was the development of versatile surface functionalization strategies for different nanoparticles ranging from diamond nanostructures to iron oxide nanoparticles, silica particles and lipid nanocapsules. One particular aim was the introduction of various functionalities onto the same nanoparticles using either dopamine-derived ligands or Cu(I) catalyzed “click” chemistry strategies. This resulted in well-dispersed nanostructures with different ligands present on the surface of the nanostructures. The possibilities to use such nanostructures for the inhibition of viral infections and for gene delivery were investigated. Indeed, inhibiting the entry of HCV has been identified as a potential therapeutic strategy. It could be demonstrated that various nanoparticles can be efficiently engineered to display “lectin-like” properties and indeed behave as effective viral entry inhibitors, in vitro. The pseudo-lectins investigated here include iron-, silica-, diamond-, (lipid nanocapsule)-derived nanoparticles all featuring surface-attached boronic acid moieties. In parallel to work on HCV entry inhibition, the potential of diamond nanoparticles as gene delivery system was investigated. Water dispersible and biocompatible polypegylated diamond particles were prepared using different dopamine ligands and their effect on gene delivery has been studied

Повний текст джерелаThis thesis describes the development of novel methods to obtain versatile, functional nanoparticles that can potentially be used for biomedical applications such as drug delivery, bioassays and bioimaging. Nanomaterials are versatile tools that have found applications as drug carriers, bioimaging or biosensing. In particular, core-shell type nanoparticles have attracted much attention due to their small size, high surface to volume ratio and biocompatibility. In this regard, we propose in the first part of the thesis (Chapter 2), a novel method to obtain core-shell nanoparticles via combined radical emulsion and living polymerizations. Polystyrene core seeds of 30-40 nm, with a narrow size distribution and surface-bound iniferter moieties were used to further initiate polymerization of a polymer shell. Core-shell nanoparticles were prepared in this way. Different types of shells : anionic, zwitterionic, thermoresponsive or molecularly imprinted shells, were thus grafted. Our method is a versatile platform with the ability to add multi-functionalities in either the core for optical sensing or/and the shell for cell interaction and toxicity studies, as well as receptor materials for cell imaging. In the second part of the thesis (Chapter 3), we describe a novel and versatile method for surface modification of upconverting nanoparticles (UCPs). UCPs are lanthanide-doped fluorescent nanocrystals that have recently attracted much attention. Their fluorescence is excitated in the near infrared, which makes them ideal as labels in biomedical applications such as bioimaging and bioassays, since the autofluorescence background is minimized compared to organic dyes and quantum dots. However, UCPs are hydrophobic and non-compatible with aqueous media, therefore prior surface modification is essential. The strategy that we propose makes use oft he UV or Vis emission light of near-infrared photoexcited upconverting nanoparticles, as secondary light source for the localized photopolymerization of thin hydrophilic shells around the UCPs. Our method offers great advantages like ease of application and rapid surface functionalization for attaching various ligands and therefore can provide a platform to prepare polymeric-encapsulated UCPs for applications in bioassays, optical imaging and drug delivery. Stimuli responsive hydrogels are materials that can change their physico-chemical properties in response to external stimuli such as temperature, pH or light. These smart materials play critical roles in biomedical applications such as drug delivery or tissue engineering. The third part of the thesis (Chapter 4) proposes a novel method for obtaining photo and pH-responsive supramolecularly crosslinked hydrogels. Two building blocks, one containing photoresponsive 4-[(4-methacryloyloxy)phenylazo] benzoic acid and the other, consisting of cationic 2-(diethylamino)ethyl methacrylate units, were first synthesized. Combining the two building blocks yielded photo and pH responsive monodisperse 100-nm particles. These nanoparticles can be eventually utilized for drug delivery, especially delivery of biomolecules such as siRNAs or proteins. In conclusion, we have designed several new efficient, versatile, generic and easily applicable methods to obtain functionalized polymer nanoparticles and nanocomposites that can be applied in various biomedical domains like drug delivery, biosensing, bioassays and bioimaging

Повний текст джерелаO estudo da simetria conforme é motivado através de um exemplo em mecânica estatística e em seguida rigorosamente desenvolvido em teorias de campos quânticos em dimensões espaciais gerais. Em particular, os campos primários são introduzidos como os objetos fundamentais de tais teorias e então estudados através do formalismo de quantização radial. As implicações da invariância conforme na forma funcional das funções de correlação são estudadas em detalhe. Blocos conformes são definidos e várias abordagens para seu cálculo analítico e numérico são apresentadas com uma ênfase especial no caso unidimensional. Com base nessas preliminares, uma formulação moderna do programa de bootstrap conforme e suas várias extensões são discutidas. Exemplos são dados em que limites nas dimensões de escala em uma teoria unidimensional são derivados numericamente. Usando esses resultados, motivei a técnica de usar o bootstrap funcional extremo, que depois desenvolvo em mais detalhes. Diversos detalhes técnicos são discutidos e exemplos são apresentados. Após uma breve discussão das teorias de campo conformes com fronteiras, eu aplico métodos numéricos para encontrar restrições no espectro do modelo de Ising em 3D. Outra aplicação é apresentada em que eu estudo a função de 4 pontos na fronteira de uma teoria particular no espaço Anti-de-Sitter, a fim de aproximar o espectro de massa da teoria.

Повний текст джерелаIn this thesis different methodologies have been used to drive the assembly at surfaces of three different (macro)molecular systems towards highly ordered supramolecular nanoscopic and microscopic structures. The structures of the thin films have been studied at the solid-air interface making use primarily of Scanning Force Microscopy (SFM). The first part of the thesis was focused on the use of the Langmuir-Blodgett (LB) technique to grow laterally ordered monolayers on mica from amphiphilic molecules having either a double or a single hydrophobic tail. Ordered monolayers were produced using two different strategies. The former exploits instability phenomena connected to the LB transfer and allows the generation of periodic nanometric channels, in dimyristoyl-phosphatidylcholine (DMPC) monolayers transferred to mica. The latter strategy consists of assembling amphiphiles having large and strongly mutually interacting heads. In this case, quercetin palmitate (QP) molecules were used to build up micrometric domains of supramolecular fiber-like structures. In the mixed films, the nanoscopic fibers were observed by tapping mode SFM to adopt a curved conformation and wrap up, leading to novel spiral-like domains. The results obtained open new perspectives to the use of LB as a tool for nanopatterning (multicomponents) monolayers with a high degree of precision. The second part of the thesis was devoted to self-assembly at surfaces of a new class of supramolecular system, based on cyclodextrin-threaded conjugated polyrotaxanes, with the final aim of optimizing the performance of LEDs based on these complex architectures. In particular the surface morphology of blends of water soluble poly(4,4'-diphenylenevinylene), PDV and of the correspondent rotaxinated form -CD-PDV, with poly(ethylene oxide), PEO, grown by spin-coating was explored by non-contact SFM. The SFM analysis revealed the occurrence of an interfacial recognition process, which is evidenced by a structural order induced by the chosen substrate, and the absence of phase segregation. This provides evidence for a good miscibility of the two hydrophilic components, as supported by luminescence data from films and devices constituted by those systems. This was also proved by the SFM analysis on sub-monolayer thick films of poly-para-phenylene based polyrotaxane (-CD-PPP) naked and blended with PEO, highlighting the interaction between the two components at single molecule level. Significant surface structures, indicative of phase separations, were instead observed when blending PEO with organic-solvent soluble conjugated polymers, such as poly(9,9'-dioctylfluorene-alt-benzothiadiazole) F8BT, and alkylated polyfluorene based CD-polyrotaxanes. The third part was addressed to the tailoring of hybrid organic-metallic nanojunctions, which are key components for future applications in the field of nanoelectronics. This required the combination of the self-assembly of molecular structures (bottom-up approach) with micro- and nano-fabrication for the production of metallic nanogaps with lithographic methods (top-down). The self-assembly behavior of a low molecular weight gelators, cyclohexane trisamide which self-associate into columnar structures through hydrogen bonding, was studied on films prepared by drop-casting. The goal was to use a DC electric field to place the well-defined ordered supramolecular arrangement in between two facing Au nanoelectrodes, supported on a silicon wafer, nanofabricated by means of Focused Ion Beam. Although the fibers tend to intercoil into super-structures, a weak propensity of these architectures to orient as a consequence of the applied electric field was found. The results described in this thesis reveal that it is of prime importance to achieve a full control over the interplay of intra-molecular as well as inter-molecular and interfacial interactions in order to drive the nanoconstruction at solid surfaces towards pre-programmed architectures with given properties. Moreover it is demonstrated that the supramolecular approach represents a successful route to fabricate prototype of molecular electronics devices with improved performance

Повний текст джерелаIn many different fields of applied statistics an object of interest is depending on some continuous parameter. Typical examples in finance are implied volatility functions, yield curves or risk-neutral densities. Due to the different market conventions and further technical reasons, these objects are observable only on a discrete grid, e.g. for a grid of strikes and maturities for which the trade has been settled at a given time-point. By collecting these functions for several time points (e.g. days) or for different underlyings, a bunch (sample) of functions is obtained - a functional data set. The first topic considered in this thesis concerns the strategies of recovering the functional objects (e.g. implied volatilities function) from the observed data based on the nonparametric smoothing methods. Besides the standard smoothing methods, a procedure based on a combination of nonparametric smoothing and the no-arbitrage-theory results is proposed for implied volatility smoothing. The second part of the thesis is devoted to the functional data analysis (FDA) and its connection to the problems present in the empirical analysis of the financial markets. The theoretical part of the thesis focuses on the functional principal components analysis -- functional counterpart of the well known multivariate dimension-reduction-technique. A comprehensive overview of the existing methods is given, an estimation method based on the dual problem as well as the two-sample inference based on the functional principal component analysis are discussed. The FDA techniques are applied to the analysis of the implied volatility and yield curve dynamics. In addition, the implementation of the FDA techniques together with a FDA library for the statistical environment XploRe are presented.

Повний текст джерелаIn this thesis we propose nonparametric counterparts to these parametric tests. Evaluating a nonparametric test statistic at each point of the parameter space, T, results in a random field, which we call a "nonparametric random field". The nonparametric tests used in this work are the Sign test, the Wilcoxon rank-sum test and a general linear rank test. We define the nonparametric random fields precisely, and then derive a formula for E[EC(Au)], when the parameter space is T = [a, b]. Although these results work only for one-dimensional parameter spaces,they constitute a solid first attempt and should pave the way for future generalizations. Moreover, we introduce a new application for the one-dimensional case, in localization of data types, in file type detection studies. We also study the asymptotic behavior of nonparametric random fields and show that the discrete nonparametric fields converge weakly to Gaussian fields, for which we are able to use the existing RFT results. These asymptotic results can be practically used for any dimension. We finally apply these asymptotic results to brain imaging data.
En imagerie fonctionelle, on cherche à localiser un effet particulier à l'aide d'une collection d'images. Il est souvent d'intérêt d'effectuer un test statistique à chaque point de l'image, et de rejeter l'hypothèse nulle stipulant "aucun effet" s'il y a preuve considérable en cette direction. À cette fin, une statistique-test devrait être évaluée à chaque point de l'image, résultant ainsi en une image statistique-test. L'image statistique-test peut être perçue comme étant un procédé stochastique ou un champ aléatoire, f, défini sur un espace-paramètre, T, et avec image en R. Quand l'image statistique-test, f, est soumise à un seuil de niveau u la p-valeur sera la probabilité d'excursion. Quand f satisfait certaines conditions, la Théorie des Champs Aléatoires (TCA) peut être utilisée afin d'estimer cette probabilité d'excursion en calculant l'espérance mathématique de la caractérisque d'Euler (CE) des ensembles d'excursion de f. Les résultats de la TCA déjà établis procurent des formules explicites pour E[EC(Au)] quand f est une fonction de champs gaussiens [26, 27]. De la perspective des tests d'hypothèse, ceci implique que le test effectué à chaque point de l'image devrait être paramétrique. Les tests paramétriques requièrent fréquemment que les observations soient normalement distribuées, bien que cette hypothèse ne soit pas toujours vraie. Si l'hypothèse de normalité est fausse, les champs aléatoires obtenues à partir de notre statistique-test ne sont pas gaussiens et conséquemment, les résultats de la TCA gaussiens sont invalides.
Dans cette thèse, on propose un homologue non-paramétrique aux tests paramétriques. L'évaluation d'une statistique-test nonparamétrique à chaque point de l'espace-paramètre, T, résulte en un champ aléatoire, que l'on nommera " champ aléatoire non-paramétrique. " Les tests non-paramétriques utilisés dans ce travail sont le test du signe, le test de la somme des rangs de Wilcoxon et le test de rangs linéaire général. On définit précisément le champ aléatoire non-paramétrique, pour ensuite dériver une formule pour E[EC(Au)] quand l'espace-paramètre est T = [a, b]. Bien que ces résultats soient uniquement valides pour des espaces-paramètre unidimensionels, ils constituent un premier pas important et devrait frayer la voie à de plus amples généralisations. De plus, on introduit une nouvelle application pour le cas unidimensionel, notamment concernant la localisation de types de données lors d'études de détection de types de fichiers. On étudie également le comportement asymptotique des champs aléatoires non-paramétriques et démontre que les champs aléatoires discrets converge faiblement vers des champs gaussiens, pour lesquelles les résults de la TAC sont applicables. Ces résultats asymptotiques s'avèrent utiles pour toute dimension. On applique finalement ces résultats asymptotiques à des données d'imagerie cervicale.

Повний текст джерелаEl dióxido de carbono (CO2) ha estado presente en la atmósfera desde las primeras etapas de la Tierra. El CO2 es uno de los gases responsables del efecto invernadero, que regula de la temperatura de la superficie del planeta. Sin embargo, su concentración en la atmósfera ha ido creciendo de forma exponencial desde la revolución industrial, especialmente en el último siglo, lo que ha implicado un efecto negativo en el clima global. Es por esto que el desarrollo de nuevas transformaciones de CO2 con el objetivo de reducir los niveles atmosféricos se ha convertido en un campo activo de investigación en las últimas décadas. Nuestro grupo se ha centrado en la utilización de CO2 para la síntesis de carbonatos cíclicos (CCs) mediante la cicloadición [3 + 2]. En este contexto, el capítulo 2 describe la síntesis y caracterización de cinco estereo/regio-isómeros de CCs a partir de un solo epoxialcohol ,derivado del ciclooctadieno, incluyendo dos CCs con configurados trans y por tanto con potencial en la aplicación de polimerización por "Ring Opening Polymeization" (ROP).

Carbon dioxide (CO2) has been present in atmosphere since early stages of the Earth. CO2 is one of the gases components responsible of the greenhouse effect, responsible of the regulation of the planet surface temperature. However its concentration in the atmosphere has been growning dramatically since the industrial revolution, specially in the last century which has implied a negative effect in the global climate. In this concern, developing new CO2 transformation with the aim of reducing atmospheric levels has become an active field of research in the last decades. Our group has focused in the utilization of CO2 for the synthesis of cyclic carbonates (CCs) via [3+2] cycloaddition. In this context, chapter 2 describes the synthesis and characterization of five CCs stereo/regio-isomers from a single epoxyalcohol derived from cyclooctadiene, including two unusual trans-configured CCs with potential in Ring Opening Polymerization (ROP) application. The third chapter focuses in the synthesis of 6-membered cyclic carbonates (6MCCs) by means of a photocatalytic process. The ROP potential of some of the 6MCCs prepared is also evaluated. Finally, chapter 4 summarises our efforts to synthesize non-isocyanate polyurethanes (NIPUs) from a biobased dicarbonate monomer, derived from beta-elemene and commercially relevant diamines. In this chapter the physical properties of one of the NIPUs synthesized are also discussed

Повний текст джерелаDevido à redução de dimensões e ao aumento da velocidade de processamento de dados nos dispositivos microeletrónicos baseados em semicondutores convencionais, estão a ser exploradas abordagens inovadoras envolvendo novos materiais tais como óxidos funcionais. Com o rápido desenvolvimento da indústria eletrónica existe uma maior necessidade de elevado desempenho, de elevada fiabilidade, e de componentes eletrónicos miniaturizados integrados em vários dispositivos. A fim de tornar os dispositivos amplamente acessíveis e de fácil utilização, requisitos adicionais devem ser considerados: o tamanho e peso desejados, o custo reduzido, o baixo consumo de energia e a portabilidade. Materiais funcionais de baixa dimensionalidade são muito promissores para cumprir essas exigências. Em particular, os ferroeléctricos de filmes finos bidimensionais (2D) têm recebido grande atenção devido à sua crescente utilização em memórias não voláteis, detectores piroelétricos, transdutores piezoeléctricos miniaturizados e dispositivos sintonizáveis de micro-ondas. A temperatura de cristalização é um parâmetro chave na preparação de ferroelétricos 2D. Muitos filmes finos ferroelétricos são cristalizados a temperaturas >600 °C. Esses valores estão acima da temperatura que certos elementos do dispositivo funcional podem suportar. Recentemente, este facto tornou-se ainda mais importante, devido às promissoras aplicações que podem ser consideradas caso os ferroeléctricos 2D sejam compatíveis com substratos poliméricos flexíveis de baixo custo e de baixo ponto de fusão. A compatibilidade de filmes finos ferróicos com estes últimos tipos de substratos é muito difícil, mas se conseguida pode ampliar acentuadamente a gama de aplicações para os mais recentes requisitos de eletrónica flexível e microeletrónica, onde dispositivos leves e baratos são exigidos. Neste trabalho, é implementada uma combinação da modificação da química de precursores e assistência por luz UV, com promoção simultânea da cristalização pela introdução de sementes nanocristalinas na solução precursora, para a fabricação de filmes finos ferróicos sem chumbo - Método de Precursores Fotossensíveis Semeados. Neste contexto, o principal objetivo deste trabalho foi fabricar filmes finos sem chumbo BiFeO3 (BFO) e Na0.5Bi0.5TiO3 (NBT) a baixas temperaturas (~300 °C) com uma resposta ferroelétrica competitiva. Além disso, a investigação do efeito do elétrodo-base sobre as propriedades dielétricas e ferroelétricas de filmes finos de BFO foi levada a cabo, e a comparação entre o comportamento de condensadores de BFO com base em IrO2, LaNiO3 (LNO) e Pt foi estabelecida. Adicionalmente, os efeitos dos vários eléctrodos sobre a microestrutura de filmes finos ferroeléctricos de BFO foram estudados por microscopia eletrónica de transmissão (TEM) de alta resolução. Primeiramente, filmes finos finos de perovesquite BFO e NBT foram preparados sobre substratos de silício revestidos com Pt, por deposição de solução química. Os filmes finos de BFO foram preparados a temperaturas na gama de 400-500 °C, a partir de soluções de precursores estequiométricas e com excesso de Bi. Os filmes de BFO cristalinos foram obtidos a 400 °C, o limite inferior de temperatura. Os filmes preparadas com excesso de Bi possuem curvas de histerese ferroelétrica mais definidas do que aqueles sem qualquer excesso, para filmes com espessuras ~150 nm. Uma vez que as densidades de corrente de fuga nos filmes finos diminuem com a diminuição da temperatura de processamento, a polarização de filmes finos de BFO preparados com excesso Bi e recozidos a 400 e 450 °C pode ser efetivamente comutada à temperatura ambiente. Obtiveram-se valores de polarização remanescente de Pr ~10 e ~60 μC/cm2 com campos coercivos de EC ~ 205 e 235 kV/cm para os filmes finos preparados a 400 e 450 °C, respectivamente. Os filmes finos de NBT foram preparados a temperaturas entre 400 e 650 °C. As propriedades estruturais e ferroelétricas dos filmes foram examinadas. A constante dieléctrica observada e as perdas dieléctricas a 100 kHz são 616 e 0,032, respectivamente, enquanto que a polarização remanescente observada e o campo coercivo são Pr ~ 24 μC/cm2 e EC ~ 215 kV/cm, respectivamente para o filme de NBT recozido a 650 °C. O recozimento térmico, em atmosfera de oxigénio após cada camada de revestimento, é eficaz na promoção da cristalização do filme na fase de perovesquite romboédrica a uma baixa temperatura de 400 °C. No entanto, obteve-se um ciclo P-E quase linear para os filmes NBT cristalizados a 400 °C devido à sua incipiente cristalinidade. Os filmes finos de BFO foram depositados numa gama de elétrodos para determinar o seu papel no controlo da formação de fases e da microestrutura. A cristalização em elétrodos de óxido seguiu a sequência: amorfa → Bi2O2(CO3) → perovesquite, enquanto que nos elétrodos de Pt cristalizaram diretamente a partir da fase amorfa. Os elétrodos de IrO2 promoveram a formação da fase de perovesquite à temperatura mais baixa e o LNO induziu adicionalmente o crescimento epitaxial local. O LNO tem a estrutura de perovesquite com o parâmetro de rede a = 0.384 nm, compatível com o de BFO, a = 0.396 nm, e assim a epitaxia é mais provável. Todas as composições exibiram precipitados inteiramente coerentes ricos em Fe dentro do interior de grão da matriz de perovesquite, enquanto que a incoerente segunda fase de Bi2Fe4O9 foi também observada nos limites de grão de BFO crescido em eléctrodos de Pt. Esta última pode ser observada por difração de raios X, bem como TEM, mas os precipitados coerentes foram observados apenas por TEM, principalmente evidenciados pelo seu contraste Z em imagens de campo escuro anular. Estes dados têm consequências acentuadas permitindo alargar a utilização de filmes de BFO sob campo aplicado, a aplicações como atuadores, sensores e aplicações de memória. Em seguida, os filmes finos de BFO foram depositados em substratos de Si com elétrodos distintos, como Pt, LNO e IrO2, para investigar o efeito do elétrodo-base sobre o crescimento e as propriedades elétricas do BFO. Todas os filmes de BFO são compostos por grãos colunares cujo tamanho é dependente do elétrodo-base. Não se observou textura para filmes de 320 nm de espessura fabricados em Pt orientado (111). Os filmes sobre eléctrodos de óxido, em particular sobre LNO são altamente orientados no plano (012). A grande polarização remanescente em BFO/Pt e BFO/IrO2 é atribuída à alta contribuição de corrente de fuga. Os filmes BFO de 400 nm de espessura em LNO possuem uma baixa densidade de corrente de fuga ~4 × 10-6 A/cm2, uma grande polarização remanescente de 50 μC/cm2 e um pequeno campo coercitivo de 180 kV/cm à temperatura ambiente. Demonstramos que as camadas de LNO aumentam a cristalinidade e a orientação de filmes finos BFO, o que se reflete nas suas propriedades funcionais. Este estudo mostra que, além da simples necessidade de filmes monofásicos, os elétrodos de óxido de metal têm um impacto relevante no desenvolvimento de filmes finos BFO de alta qualidade fabricados por métodos químicos de deposição de solução. Estes resultados têm uma implicação grande para a fabricação de dispositivos BFO baseados em filmes finos. Finalmente, provamos que é possível fabricar diretamente filmes finos de BFO sem chumbo em substratos flexíveis de poliamida com funcionalidades ferroelétricas e magnéticas (multiferroicidade) à temperatura ambiente. O nosso método inovador, baseado em soluções de Precursores Fotossensíveis e nanosementes cristalinas, foi usado com sucesso para diminuir a temperatura de cristalização de filmes finos de BFO até uma temperatura tão baixa quanto 300 °C, a mais baixa temperatura reportada até agora para a preparação de filmes finos multiferróicos de BFO. Apesar deste excepcionalmente baixo nível térmico, obtém-se uma polarização remanescente Pr de 2.8 μC/cm2 para os filmes semeados + UV, com um campo coercitivo EC de 300 kV/cm. A estratégia de síntese baseada na utilização de precursores fotossensíveis sementados pode ser transferida para qualquer outra família de óxidos metálicos funcionais.
With the dimensions reduction and data processing speeds increasing of conventional semiconductor based microelectronic devices, innovative approaches involving new materials such as functional oxides are being explored. With the rapid development of the electronics industry there is a need for high performance, high reliability and miniaturized electronic components integrated into various devices. In order to make the devices user friendly and widely accessible, additional requirements should be considered: the desired size and weight, low cost, low power consumption, and portability in addition to high levels of functionality. Low dimensional functional materials hold great promises to fulfil those requirements. In particular, two-dimensional (2D) thin film ferroelectrics have received wide attention because of their growing use as non-volatile memories, pyroelectric detectors, miniaturized piezoelectric transducers and tunable microwave devices. Crystallization temperature is a key parameter in preparation of 2D-ferroelectrics. Many ferroelectric thin films are crystallized at temperatures >600 °C. This is above the temperature that certain elements of the functional device can withstand. Recently it became even more important due to promising applications that can be envisaged if 2D-ferroelectrics will be compatible with low cost, low melting temperature flexible polymeric substrates. The compatibility of ferroic thin films with those last types of substrates can markedly widen the range of applications towards the most recent requirements of flexible electronics and microelectronics, where lightweight and cheap devices are demanded. In this work, a combination of the modification of precursor chemistry and the assistance of UV-light, with simultaneous promotion of crystallization by introducing nanocrystalline seeds in the precursor solution, is implemented to fabricate lead-free ferroic thin films - Seeded Photosensitive Precursor Method. Within this context, the main objective of this work was to fabricate lead-free BiFeO3 (BFO) and Na0.5Bi0.5TiO3 (NBT) thin films with a competitive ferroelectric response at low temperatures. Moreover, investigations of the effect of the bottom electrode on the dielectric and ferroelectric properties of BFO thin films was conducted and the comparison between the behavior of IrO2, LaNiO3 (LNO) and Pt based BFO capacitors established. Additionally, the effects of these various bottom electrodes on the microstructure of BiFeO3 ferroelectric films was studied by high-resolution TEM. Firstly, BFO and NBT perovskite thin films were prepared on Pt-coated silicon substrates by chemical solution deposition. BFO was prepared at temperatures in the range 400-500 °C, and from stoichiometric and Bi excess precursor solutions. Crystalline BFO films were obtained at the lowest temperature limit of 400 °C. The films prepared with Bi excess possess more defined ferroelectric hysteresis loops than those without any excess; for films with thicknesses ~150 nm. As the leakage current densities in the films decrease with decreasing the processing temperature, polarization of BFO films prepared with Bi excess and annealed at 400 and 450 °C can be effectively switched at room temperature. Remanent polarization values of Pr ~ 10 and ~60 μC/cm2 with coercive fields of EC ~ 205 and 235 kV/cm were obtained for the films prepared at 400 and 450 °C, respectively. NBT thin films were prepared at temperatures from 400 to 650 °C. Structural and ferroelectric properties of the films were examined. The observed dielectric constant and dielectric losses at 100 kHz are 616 and 0.032, respectively, while the observed remanent polarization and coercive field are Pr ~ 24 μC/cm2 and EC ~ 215 kV/cm, respectively for the NBT film annealed at 650 °C. Thermal annealing in an oxygen atmosphere after each layer of coating is effective in promoting crystallization of the film into rhombohedral perovskite phase at a low temperature of 400 °C. However, almost linear, P-E loop was obtained for those NBT films crystallized at 400 °C due to incipient crystallinity. BFO thin films were grown on a range of electrodes to determine their role in controlling phase formation and microstructure. The crystallization on oxide electrodes followed the sequence: amorphous → Bi2O2(CO3) → perovskite, while those on Pt crystallized directly from the amorphous phase. IrO2 electrodes promoted perovskite phase formation at the lowest temperature and LaNiO3 additionally induced local epitaxial growth. LNO has the perovskite structure with lattice parameter a = 0.384 nm, compatible with that of BFO, a = 0.396 nm and thus epitaxy is more likely. It was observed for the first time that all compositions exhibited fully coherent Fe-rich precipitates within the grain interior of the perovskite matrix, whereas incoherent Bi2Fe4O9 second phase was also observed at the grain boundaries of BFO grown on Pt electrodes. The latter could be observed by X-ray diffraction as well as transmission electron microscopy (TEM) but coherent precipitates were only observed by TEM, principally evidenced by their Z contrast in annular dark field images. These data have pronounced consequences for the extended use of BFO films under applied field for actuator, sensor and memory applications. Then, BFO thin films were deposited on Si-based substrates with distinct electrodes, such as Pt, LNO, and IrO2, in order to investigate the effect of bottom electrode on the growth and electrical properties of BFO. All BFO films are composed of columnar grains which size is dependent on the bottom electrode. No texture was observed for 320 nm thick films fabricated on (111) oriented Pt. Films on oxide electrodes, in particular on LNO are highly (012) oriented. The large remanent polarization in BFO/Pt and BFO/IrO2 is attributed to the high leakage current contribution. 400 nm thick BFO films on LNO possess a low leakage current density ~4 × 10-6 A/cm2, a large remanent polarization of 50 μC/cm2 and a small coercive field of 180 kV/cm at room temperature. We demonstrate that LNO layers enhance the crystallinity and orientation of BFO thin films, which is reflected in their functional properties. This study shows that besides the simple need of monophasic films metal oxide electrodes have a relevant impact on the development of high quality BFO thin films fabricated by chemical solution deposition methods. These results have a broad implication for the fabrication of BFO thin film based devices. Finally, we prove that it is possible to directly fabricate lead-free BFO thin films on flexible polyamide substrates with ferroelectric and magnetic functionalites (multiferroicity) at room temperature. Our own proprietary novel solution-based Seeded Photosensitive Precursor Method was successfully used to decrease the crystallization temperature of BFO thin films down to a temperature as low as 300 °C, the lowest reported up to now for the preparation of multiferroic BFO thin films. Despite this exceptionally low thermal budget a remanent polarization Pr of 2.8 μC/cm2 is obtained for the seeded + UV films, with a coercive field EC of 300 kV/cm. The synthesis strategy based on the use of seeded photosensitive precursors can be transferred to any family of functional metal oxide.

Повний текст джерелаThis work presents functional composition (FC) as a new paradigm for combinational logic synthesis. FC is a bottom-up approach to synthesize Boolean functions, being able to evaluate the cost of intermediate sub-functions, exploring a larger number of different candidate combinations. These are interesting advantages when compared to the top-down behavior of functional decomposition. FC presents great flexibility to implement algorithms with optimal or suboptimal results for different applications. The proposed strategy presents good results for the synthesis of Boolean functions targeting different technologies. FC is based on the following principles: (1) the representation of logic functions is done by a bonded pair of functional and structural representations; (2) the algorithm starts from a set of initial functions; (3) simpler functions are associated to create more complex ones; (4) there is a partial order, enabling dynamic programming; (5) a set of allowed functions can be used in order to reduce execution time/memory consumption. This work presents functional composition algorithms for Boolean factoring, including optimal factoring, Boolean factoring considering the exclusive-OR operator, minimum decision chain computation and synthesis of functions considering only majority and inverter logic gates.
