Pełny tekst źródłaTiivistelmä Tässä väitöskirjatyössä tutkitaan orgaanisten valoa emittoivien transistoreiden (OLET) ja diodien (OLED) värinsäätöä. Työssä tehtiin kolmikerrosrakenteisia OLETeja, jotka kykenevät emittoimaan valoa kahdella värillä ja joiden emittointiväri on jännitesäädettävissä. OLEDien osalta toteutettiin kaksi erilaista värinsäätömenetelmää, joissa molemmissa hyödynnettiin kuumennusta pysyvän värinvaihdon aikaansaamiseksi. Tutkitut OLETit emittoivat punaista ja vihreää valoa. Aluksi tutkittiin vastaavia komponentteja, jotka emittoivat vain punaista valoa. Näissä komponenteissa punaisen valon tuotti keskimmäinen valoemitterinä toiminut kerros (Alq3:DCM), jonka ala- ja yläpuolella olivat aukko- ja elektronijohtavat kerrokset (DH-4T ja DFH-4T). Komponenteilla saatiin tuotettua myös vihreää valoa, kun valmistusprosessia kehitettiin tasaisempien aktiivisten materiaalikerrosten valmistamiseksi. Vihreän valon todettiin olevan elektronijohtavan kerroksen tuottamaa. Kaksiväriemittoiva OLET tuotti vihreää valoa ollessaan elektronijohtavassa tilassa, ja punaista valoa aukkojohtavassa tilassa, emittointivärin ollessa näin jännitesäädettävissä. Työssä tutkittujen OLEDien valon emittointi perustui polymeerikerrokseen, joka oli toisissa OLEDeissa seostamaton ja toisissa seostettu. Seostamattomien OLEDien aktiivinen kerros oli tehty sinistä valoa tuottavasta polyfluoreenista (PFO), jossa usein ilmenee keto-virheitä, joiden vuoksi PFO:sta tehtyjen OLEDien valo muuttuu sinisestä vihertäväksi. Työssä osoitettiin, että kuumennusta voidaan käyttää sinisen emittointivärin palauttamiseen. Seostettujen OLEDien (PFO:F8BT) osalta kuumennusta käytettiin komponenttien emittointivärin muuttamiseksi alkuperäisestä emittointiväristä vihreästä valkoiseksi. Tämä ilmiö selitettiin valoa emittoivan kerroksen polymeerien välisellä faasierkaantumisella

Organic light emitting devices (OLEDs) are brightly emissive, efficient, have fast switching speeds, and are paper-thin in format, propelling their use as an emerging flat panel display technology. However, two primary challenges prevent OLEDs from dominating the large-area display market: the extension of OLED display lifetime and development of simple, scalable fabrication techniques compatible with small molecule organic thin films. The principle contributions we report are (1) introduction and analysis of a novel optical feedback technique for extending the lifetime of OLED displays (2) the experimental demonstration and theoretical analysis of contact stamping for patterning multi-color OLED displays.

Pełny tekst źródłaIn this work a potential new OLED application is presented: a large-area purple OLED for horticultural application, which combines red and blue light emissions in a unique device. The main issue of this thesis is to demonstrate the effectiveness of the proposed OLED structure by using theoretical models created during the three years of the Ph.D. studies and applied to commercial materials. The core of this dissertation is the third chapter, where the reader is brought to the optimization of the final purple OLED structure after several experiments, which confirm either the basic concepts explained in the two previous chapters, either a mathematical model for a fine-tuning of the blue emission layer. Behind the proposed device architecture and material employed, there is the concept of “hybrid OLEDs with triplet harvesting”, where a proper combined use of fluorescent and phosphorescent emitting materials allows a theoretical internal quantum efficiency of 100%. The last chapter is focused on the study and the realization of metal grids on the indium-tin-oxide (ITO), which is the most used material as transparent and conductive anode for the OLED devices. Despite ITO owns good property of transmittance (transparency), because of its limited conductivity, a lateral voltage drop occurs, preventing a homogeneous emission when the dimensions of the devices exceeds few square centimetres. To overcome this problem, it is presented a new mathematical model which, unlike the most established literature models do, takes into account both the electrical influence of the metal grid and that one of the ITO. Finally, with a good agreement with the experimental data, the theoretical model is used to predict optical and electrical behaviour of different hexagonal metal grid on ITO. It worth to underline that all the approaches implemented in this work to achieve a large-area purple OLED, have a general validity. Indeed, the entire know-how in this thesis it has been successfully used, in the last three years, to make several different OLED devices, different for colour emission, size and performances.

Pełny tekst źródłaThis thesis explores various meanings of ethnicity and race and different dimensions of social interaction between Namibian groups from the viewpoint of young urban Namibians living in Windhoek. Furthermore, this thesis examines other significant identities of the youth: national, urban, African and global identities, and their social meanings. Research material consists of 22 individual interviews of tertiary educated urban Namibians from different ethnic backgrouds in the age group of 20–30 years. The focus of the research is in the emic meanings and interpretations of social belonging given by the young Namibians. In this study ethnicity, race and nationalism are examined as processes of social construction, meaning how these identities are produced and also challenged in the narratives. The young educated Namibians live a modern lifestyle in a socially vibrant urban environment of the capital city, where interaction between various groups of people is an essential part of everyday life. Ethnic and racial background, education, modern city lifestyle and higher social-economic standing in the society have an influence on the young Namibians’ interpretations of social belonging related to ethnicity, race and nationalism. Moreover, Namibia’s ethnically and racially segregated apartheid past has left its mark on the various meanings of ethnicity and race, and influenced the characteristics of interactions between groups of people in Namibia. This study demonstrates that ethnicity, race and nationalism are partly overlapping, intertwined and in many respects contradictory cultural ways to categorize other people and to define one’ place in the Namibian social environment. According to young Namibians’ experience, ethnicity is an important form of categorization and social belonging that is built through boundary making and maintenance. The boundaries between ethnic groups are real to the youth, but they do not always appear as concrete differences between groups. The meaning of boundaries is constructed symbolically. Social belonging related to race is also expressed through boundaries, however the social meanings of race differ significantly from that of ethnicity. White, black and colored are three socially constructed categories of race in Namibia that are criticized as well as maintained by the young Namibians. Interaction between various ethnic and racial groups is shaped by situational factors and social context, in which the boundaries between interethnic interactions are more flexible and sensitive to negotiation than between interracial interactions. Nationalism in turn is expressed through sense of connection and sameness linked to Namibian community, especially visible when in contact with international environments. In addition to collective side of Namibian identity, it also represents an individual side of the young Namibians, whereby individual freedom is a significant factor. Moreover, urban identity and world citizenship are important identities, for they offer possibilities for broader interpretations, and also critique, on ethnicity, race and national belonging. Findings of this research offer a new perspective on the research landscape of social belonging and interactional studies in Namibia. However, there is a need for more emic-based interethnic identity studies

Resumo: o processo atual (ou convencional) de refino químico de óleos vegetais gera grande quantidade de efluentes líquidos, devido a utilização de água no processo, principalmente na etapa de desacidificação, onde ácidos graxos livres são neutralizados mediante adição de uma solução aquosa de NaOH, transformando estes compostos em sabões, insolúveis em óleo. Estes são retirados por centrifugação, seguida de uma ou duas lavagens com água quente, sobrecarregando e onerando o tratamento dos efluentes ou acarretando graves prejuízos ecológicos, caso não haja um tratamento adequado. A modificação desta etapa por uma operação que elimine uso de solução aquosa e lavagens, seria de grande interesse, não somente do ponto de vista dos efluentes, mas também pela simplificação do processo e equipamentos necessários, reduzindo, consequentemente, os custos de operação e investimento. Neste trabalho propõe-se um procedimento alternativo de neutralização de ácidos graxos livres que elimine a utilização de água no refino de óleos vegetais. Na primeira etapa deste trabalho foram estudadas as condições da utilização de silicatos impregnados com KOH, e misturas destes com seqüestrantes de sabões e argilas clarificantes, para efetuar a neutralização e clarificação de óleo de soja degomado; incluindo um estudo preliminar da etapa de filtração. As condições ótimas do processo foram determinadas pela metodologia estatística de análise de superficie de resposta. Efeitos da temperatura, concentração de álcali e tempo de contato foram determinados seguindo-se um desenho experimental fatorial 33com análise de superficie de resposta. A segunda etapa visou o "scale up" do processo em planta piloto, incluindo a desodorização do óleo obtido e sua comparação com óleo de soja refinado disponível no mercado. O processo desenvolvido indica que é possível obter óleo neutro com 0,09% de acidez residual quando tratado com 7,5% de silicato (impregnado a 10%)por 15minutos a 70°C.
Abstract: The current chemical refining process (or conventional) of vegetable oils generates a great amount of liquid waste water, due to the usage of water in the process, mainly in the desacidification step, where the ftee fatty acids are neutralized through the addition of an aqueous solution ofNaOH, transforming these compounds in soaps (soapstock), oi! insoluble. These are removed by centrifugation, followed by one or two hot water washing steps, overloading and making the waste water treatment costly or leading to severe environment damages, in case the treatment is not appropriate. The modification of this step for an operation that eliminates the use of an aqueous solution and the washing steps would be of great interest, not only on the wastewater point of view but also by the simplification of process and needed equipment. Reducing, as a consequence, the operation and investment costs. In this essay was used, in substitution of the alkali solution, a 10 % KOH impregnated silicate. Which was directly added to the degummed soybean oi! (FFA=O.7%). In the first part of this work the utilization conditions of KOH impregnated silicates, and mixtures of them with bleaching clays was studied, including a preliminary study of the filtration step. The optimum process conditions were determined by the response surface analysis statistic methodology. The second part of this work aims the process scale up in pilot plant, including the deodorization of the obtained oil and its comparison with refined commercial soybean oil. The effects of temperature, alkali concentration and contact time were determined following a 33 experimental design with surface response analysis. The process optimization indicates that it is possible to obtain neutral oils with 0.09% ofresidual acidity when treated with 7,5% silica (10% impregnated) for 15 minutes at 70°C.

Pełny tekst źródłaThis study focuses on the development of high brightness OLED microdisplays based on active matrix (AMOLED). Because these devices are used into near-to-eye (NTE) applications and more precisely « see through » optical systems, high luminances are required. Compared to conventional microdisplays, the high luminances expected are around ten times higher.In order to emit a white spectrum from a top-emitting OLED (TE-OLED), color filters are mandatory to generate the RGB primaries. Nevertheless, by using these filters, the luminance is dramatically reduced because of the light absorption. Therefore, to be free of the filters, a first study is dedicated to the modulation of the optical cavity of the OLED. In this case, the direct generation of the colors is provided by the variation of the TCO anode thickness.The cavity effect observed into the TE-OLED depends on the semi-transparent cathode. The selectivity of the related cavity represents the bottleneck for emitting broad white spectra. To improve the white emission, a second approach deals with the realization of a TCO cathode coupled with a metallic grid.The appropriated materials and deposition techniques were firstly investigated before the characterization of OLED using a transparent anode to modulate the cavity in one hand and a transparent cathode to increase the light emission in another hand. Optical simulations and electrical modelling were employed to highlight the main behaviors driving these OLED. Following a discussion about the strength and the weakness of each structure, some hints of improvement were given

Pełny tekst źródłaThis study focuses on the realization of a high brightness OLED micro-écran on silicon. The limited efficiency of White-OLED combined with color filters prevents the use of this technology in “see-through” applications. We propose a novel approach getting benefits from the optical micro-cavity effect in Top-Emitting OLED to generate colors without using color filters. Cavity modulations at a sub-pixel scale are realized by using a Transparent Conducting Oxide between the anode and the OLED.Following a step-by-step reasoning the work offers to follow all the phases of the realization of a prototype using this principle. In the first part, the technological steps of the processing of oxide cavities with a surface of 16µm² will be discussed. Then we will work on the development of a tandem OLED structure using both fluorescent and phosphorescent emitters optimized for micro-cavities. To this end optical simulation will be used. The two technological blocs will finally be put together to enlighten some issues specific for micro-écran technology and to give some clues to solve them

Resumo: O interesse por gorduras isentas de ácidos graxos trans para utilização em produtos industrializados aumentou consideravelmente na última década. Muitas destas gorduras são obtidas pela combinação de processos como interesterificação, hidrogenação total ou fracionamento. O grande desafio dos produtores destas frações oleosas é manter as características funcionais, ser viável economicamente, mas sem elevar drasticamente o conteúdo de ácidos graxos saturados. Essas frações são uma alternativa para substituição da gordura vegetal parcialmente hidrogenada em diversos alimentos, como, por exemplo, em biscoitos, consumidos principalmente por crianças. A legislação brasileira exige que, a partir de julho de 2006, os alimentos comercializados devem expressar em seus rótulos o teor declarado de trans. Os óleos de soja e de palma são mais disponíveis comercialmente e apresentam-se como matérias-primas interessantes para a elaboração de frações gordurosas isentas de trans. A produção de gorduras zero-trans foi realizada através da interesterificação química de misturas de óleo de palma e óleo de soja totalmente hidrogenado, utilizando-se o catalisador metóxido de sódio, temperaturas de aproximadamente 100oC, sob vácuo e agitação, nas proporções 98/2, 96/4, 92/8, 90/10 de PO/FHSO. Estas proporções foram determinadas como possibilidade de aplicação em recheios para biscoitos ou outros alimentos com características similares. Além destas frações, analisou-se também a reação química da estearina de palma nas mesmas condições. O estudo dos perfis das formulações foi realizado através da comparação das amostras antes e após a reação, além da avaliação de amostras comerciais. Através da composição em ácidos graxos, composição triacilglicerólica, ponto de fusão e comportamento de cristalização, escolheu-se a formulação F4, contendo 96% de palma e 4% de óleo de soja totalmente hidrogenado, após interesterificação para aplicação em recheios de biscoitos ou similares. As outras frações interesterificadas tiveram performance bastante similar em termos de melhoria do hábito cristalino. Em paralelo a este estudo, realizou-se a adição de aditivos ao óleo de palma antes e após a reação de interesterificação química para beneficiar a cristalização lenta característica deste tipo de matéria-prima. Verificou-se que o uso de monoacilglicerol de cadeia longa (C22:0) misturado ao óleo de palma pode ser uma alternativa para acelerar o processo de cristalização de frações oleosas
Abstract: The interest in zero trans fat acids to be utilized in industrialized products has been intensively increased in the last decade. Many of these fats are obtained by the combination of processes, such as interesterification, fully hydrogenation or fractionation. The producers¿ big challenge is to maintain the functional characteristics of the lipid fraction, to be economically feasible, without no drastically rising the saturated fat content. These fractions are an alternative for substituting partially hydrogenated vegetable fat in several foods, for example in cookies, consumed mainly by children. The Brazilian regulation has imposed that commercialized food must express in their labels the trans content since July, 2006. Soybean and palm oils are the most commercially available oils and consist of interesting raw materials to elaborate zero trans fatty fractions. The production of zero trans shortenings in the ratios 98/2, 96/4, 92/8, 90/10 of PO/FHSO was done by chemical interesterification of mixtures of palm and fully hydrogenated soybean oil, under vacuum and agitation, using sodium methoxide as catalyst and temperatures of approximately 100 ºC. These ratios were determined as a possibility for application in cookies¿ fillings and other foods with similar characteristics. Besides these fractions, it was also analysed the chemical reaction of palm stearin in the same conditions. The studies of formulations¿ profiles as well as commercial products were done by comparing samples before and after reaction. Formulation F4, containing 96% palm oil and 4% fully hydrogenated soybean oil after interesterification, was chosen for application in cookies and similar products, because of its fatty acid composition, triacylglycerol composition, melting point and crystallization behaviour. The other interesterificated fractions presented very similar performance in terms of the improvement of the crystallization tendency. Simultaneously to this study, it was added additives to palm oil before and after the chemical interesterification reaction to benefit the slow crystallization that is characteristic of this raw material. It was concluded that the use of long chain monoacylglycerol with palm oil can be an alternative to accelerate the crystallization process of fats

Resumo: Campos no Canadá e na Venezuela contendo reservatórios de óleo espumoso apresentaram recuperação primária da ordem de 10 a 15 % maior do que a estimada por simuladores numéricos Black-Oil. Além do alto fator de recuperação, foram observadas outras características não convencionais, como baixa razão gás-óleo e alta manutenção da pressão de reservatório. Esta discrepância entre o fator de recuperação estimado e o real é atribuída ao fato de que os simuladores Black-Oil não descrevem adequadamente o comportamento do gás em óleos espumosos. Nesta pesquisa são descritos e comparados três modelos numéricos de óleo espumoso propostos para o simulador pseudo-composicional CMG Stars. Estes modelos permitem descrever as etapas de evolução do gás, que compreendem desde a nucleação das bolhas de gás, o crescimento das bolhas, até a formação de uma fase conectada de gás, com reações cinéticas. Além disso, admite a presença de diferentes formas de gás ¿ gás em solução, gás preso, gás disperso e gás livre - nas fases gás e óleo. A mobilidade da fase gás é avaliada por uma composição de curvas de permeabilidade relativa ao gás. Com o estudo da influência de alguns parâmetros, algumas características típicas de reservatórios de óleo espumoso são explicadas, como a baixa produção de gás, o escoamento do gás na forma dispersa, a alta saturação crítica de gás e as altas razões de produção de óleo
Abstract: Fields in Canada and Venezuela, which contain foamy oil reservoirs, have exhibited a primary oil recovery on the order of 10 to 15 % greater than the recovery estimated by black-oil simulators. Besides the high oil recovery, other unusual characteristics have been observed, as low gas-oil ratio and high reservoir pressure maintenance. Such discrepancy between estimated and the actual oil recovery factor is attributed to the fact that black-oil simulators do not describe adequately gas behavior in foamy oils. In the present study, three numerical models of foamy oil behavior are described and compared using the pseudo-compositional simulator CMG Stars. These models allow describing the steps of gas evolution, since the nucleation of the gas bubbles, the bubble growing, until its connection to form a free phase, via kinetic reactions. The model admits the presence of different forms of gas ¿ solution gas, entrained gas, dispersed gas and free gas ¿ in the oil and gas phases. The mobility of the gas phase is evaluated by a composition of relative permeability curves. After the study on the influence of some parameters, some typical characteristics of the foamy oil reservoirs are explained, as the low gas production, the dispersed gas flow, the high critical gas saturation and the high oil production rates

Este trabalho apresenta o estudo e a implementação de um conversor eletrônico para a realização do acionamento de um dispositivo de iluminação à OLED (LED orgânico). É proposto um conversor Buck operando com controle da corrente de saída para acionar este dispositivo. A frequência de comutação utilizada neste conversor é na ordem de centenas de kilohertz até um megahertz, possibilitando a redução do tamanho dos elementos passivos. Devido a característica elétrica do dispositivo OLED a potência envolvida é inferior a cinco watts. Como consequência, as perdas nos componentes e nos circuitos auxiliares possuem uma influência significativa na composição do rendimento. Por isto, também são estudadas e testadas algumas técnicas que podem possibilitar um aumento no rendimento da estrutura, formada pelo conversor eletrônico mais o dispositivo de iluminação, através da substituição ou da inclusão de alguns componentes no conversor Buck ou da utilização de outro conversor eletrônico visando à redução nas perdas.
This paper presents the study and implementation of an electronic converter for driving an OLED lighting device. A Buck converter operating with control of the output current is proposed to drive this device. The switching frequency used in this converter is in the order of hundreds of kHz to a MHz, allowing a reduction in the size of the passive elements. Due to the electrical characteristic of OLED device, the power involved is less than five watts. The components and auxiliary circuits losses have a significant influence on the composition of efficiency. Therefore, some techniques that can enable an increase in the efficiency of the structure are studied and tested, formed by the electronic converter and the lighting device. The techniques replace or add a few components in the Buck converter or using another electronic converter in order to reduce losses.

Pełny tekst źródłaDiese Arbeit richtet ihren Fokus auf die Untersuchung der Leistungsfähigkeit von phosphoreszenten, Licht-emittierenden organischen Dioden (OLEDs) im Bereich hoher Betriebshelligkeiten. Phosphoreszente Emittermoleku ̈le werden in OLEDs eingesetzt, um interne Elektron-Photon Konversionseffizienzen von 100% zu erreichen. Begründet in ihrer chemischen Struktur, weisen die angeregten Triplett-Zustände dieser Emitter um Größenordnungen längere Zeitkonstanten als die Emission fluo- reszenter Materialien auf, sodass die Wahrscheinlichkeit bimolekularer Auslöschung stark ansteigt. Dies resultiert in einem deutlichen Effizienzrückgang phosphoreszenter OLEDs bei großen Leuchtdichten. Dieser als Roll-off bekannter Effekt wird bei hohen Anregungsdichten hauptsächlich durch Triplett-Triplett Annihilation (TTA) bestimmt. In der Arbeit wird TTA an einem Modellmolekül, dem phosphoreszenten Emit- ter Ir(ppy)3, in zeitaufgelösten Photolumineszenz Experimenten untersucht. Für das bekannte Emittersystem CBP:Ir(ppy)3 wird bei hohen Anregungsdichten Host-Guest TTA beobachtet, was einen zusätzlichen, ungewünschten TTA Kanal darstellt. Dieser Effekt wird durch das Verwenden von Matrix Materialien mit höherer Triplett Energie vermieden, jedoch zeigt sich in weiteren Untersuchungen, dass der Roll-off deutlich stärker ist als von einem auf Förster Energieübertrag basierendem Modell vorhergesagt, welches selbst ein intrinsisches Limit für TTA in phosphoreszenten Systemen beschreibt. Die Diskrepanz zwischen experimenteller Beobachtung und Modellvorhersage wird durch eine starke Tendenz des Emitters, Aggregate zu bilden, erklärt, was TTA deutlich verstärkt. Diese Aggregate werden mit Hilfe von Transmissionselektronenmikroskopie an Ir(ppy)3-dotierten Mischsystemen direkt nachgewiesen. Basierend auf diesen Resultaten werden zwei Konzepte entwickelt, um die Effizienz phosphoreszenter Systeme bei hohen Helligkeiten zu verbessern. Im ersten Ansatz werden dünne intrinsische Schichten des Matrixmaterials in die Emissionsschicht eingebaut, was die Exzitonenbewegung in einer Raumrichtung und damit auch TTA stark unterdrückt. Das zweite Konzept reduziert den Effizienz Roll-off durch die Verwendung eines phosphoreszenten Emitters Ir(ppy)2(acac) mit einer leicht abgeänderten Molekularstruktur. Im Vergleich mit Ir(ppy)3 weist dieser ein deutlich kleineres Dipolmoment im molekularen Grundzustand auf, wodurch die Aggregation vermindert wird. Aufbauend auf den Ergebnissen der TTA wird ein neuartiges Emissionsschicht-Design für weißes Licht entwickelt. In diesem Konzept werden drei phosphoreszente Materialien für blaue, grüne und rote Farbe in eine Vielschicht-Architektur eingebracht. Das Hauptmerkmal der Emissionsschicht ist die Wahl des Matrix-Materials für dem blauen Emitter FIrpic: Seine Triplett Energie liegt resonant zu dem FIrpic Triplett Zustand, wodurch niedrige Betriebsspannungen und hohe Leistungseffizienzen ermöglicht werden, da die thermische Relaxierung reduziert wird. Um die Ef- fizienz dieser weißen OLEDs weiter zu erhöhen, wird die entwickelte OLED Architektur zusätzlich durch die Verwendung von hochbrechenden Substraten und dicken Elektronen-Transportschichten optisch optimiert. Bei beleuchtungsrelevanten Helligkeiten erreichen diese OLEDs das Effizienzniveau von Leuchtstoffröhren – letztere stellen heute den Effizienz-Maßstab dar
