▼ Polymer light-emitting electrochemical cells (LECs) are unique solid-state light-emitting devices operating on the principle of in situ electrochemical doping and the formation of a p-n junction. Compared to conventional polymer light-emitting diodes, LECs possess some favorable device characteristics, making them attractive candidates for flat panel display applications. However, the underlying operating mechanism of LECs has been the subject of intense scrutiny and debate. The extremely large planar devices demonstrated by Dr. Gao’s group offer an unparalleled spatial resolution for investigating the electrochemical doping process. With time-lapse fluorescence imaging, our group has demonstrated the existence of the electrochemical doping and the p-n junction in an operating LEC. However, the LEC electronic structure has never been adequately studied and understood. In this thesis, the original research on the electrical and optical scanning measurements on extremely large planar LECs is described. A fresh LEC film has, for the first time, been turned on to form a light-emitting p-n junction by biasing a pair of probes that form direct contacts with the LEC film. The quasi-one-dimensional probe tips allow insight into the electrochemical doping mechanism, without being disturbed by imperfections in the pre-deposited electrodes. Time-lapse fluorescence imaging has exhibited p- and n-doping of various shapes and shades, p-n junction electroluminescence, and the effects of bias reversal. The observed doping reaction kinetics suggests that n-doping is reaction-limited whereas p-doping is diffusion-limited. Furthermore, the electric potential and conductivity distributions of extremely large planar LECs have been mapped. The results show that the p-doping is more conductive than n-doping. More importantly, The results provide the first evidence that the p-n junction is indeed a graded one with decreasing conductivity and doping concentration from the electrode contact to the metallurgical junction. In addition, the optical beam induced current (OBIC) measurement has been explored to map the built-in electric field of extremely large planar LECs. This result clearly shows that a large electric field exists only around the junction region rather than in the electrode region. Moreover, the result confirms that the LEC electronic structure is a graded p-n junction.

La cellule électrochimique électroluminescente (LEC) est un dispositif à couches minces, composé d’un semi-conducteur organique électroluminescent (OSC) et d’ions mobiles en tant que matériau actif intercalé entre une anode et une cathode. Dans le premier chapitre, le contexte et le mécanisme de la LEC ont été introduits. Dans le deuxième chapitre, nous avons dopé la molécule organophosphorée dans un verre de silicate contenant une teneur élevée en lithium par la méthode sol-gel. Dans le troisième chapitre, nous avons travaillé à l’obtention d’un verre de phosphate dopé à une molécule organophosphorée avec une conductivité ionique élevée par frittage Spark Plasma Sintering (SPS). Un verre de phosphate hybride ayant une conductivité ionique d'environ 10 -7 S / cm a été obtenu et une forte photoluminescence a été observée. En outre, les propriétés électrochimiques ont également été étudiées. De plus, lors du processus de préparation de la LEC par SPS, un phénomène intéressant a été découvert. Une émission bleue à large bande a été observée dans le verre d’oxynitrure de phosphate de zinc exempt de terres rares. Le quatrième chapitre est consacré à ce phénomène.

The light-emitting electrochemical cell (LEC) is a planar layered device, which is comprised of an electroluminescent organic semiconductor (OSC) and mobile ions as the active material sandwiched between an anode and a cathode. Electrolyte is one of the “short slab” of LEC technology. The main objective of this work is developing a new LEC device based on organophosphorus molecule doped organic-inorganic hybrid glass electrolyte. This hybrid glass cannot be synthesized by using classic melt-quenching technique because the melting temperature of glass is always much higher than the degradation temperature of organic molecule. Thus, in this work, we devote to that how to dope the organophosphorus molecule into the glass with high ionic conductivity. In first chapter, the background and mechanism of LEC were introduced. In the second chapter, we attempted to dope the organophosphorus molecule into silicate glass containing high lithium content by sol-gel method. In third chapter, we are working to obtain organophosphorus molecule doped phosphate glass with high ionic conductivity through spark plasm sintering (SPS). A hybrid phosphate glass with ionic conductivity of around 10 -7 S/cm was obtained, and strong photoluminescence was observed. Besides, the electrochemical properties were investigated as well. Moreover, during the process of preparing the LEC by SPS, an interesting phenomenon was found. A broadband blue emission was observed in rare-earth free zinc phosphate oxynitride glass. The fourth chapter is focus on this interesting phenomenon.

A fala privada, de acordo com Wertsch (1980), é definida como um diálogo que o indivíduo promove consigo mesmo e sua função recai na necessidade da autorregulação, autodirecionamento e autorreflexão. Os estudos sobre fala privada de crianças e adultos foram pesquisados por McCafferty (1994), Berk & Spuhl (1995), Fernyhough & Russell (1997), Krafft & Berk (1998), Winsler, Carlton, Barry (2000), Manfra & Winsler (2006), Smith (2007), Day & Smith (2013), entre outros. Entretanto, o estudo da fala privada não foi investigado pelas pesquisas de Língua Estrangeira para Crianças (LEC) no Brasil. Dessa forma, essa pesquisa de mestrado se insere na lacuna existente na falta de estudos sobre a fala privada como uma importante ferramenta cognitiva no processo de ensino-aprendizagem da Língua Inglesa (LI). Nos estudos do LEC e de ensino-aprendizagem de língua estrangeira em geral, a língua é considerada somente uma fonte de comunicação. O propósito desse estudo foi verificar como a fala privada ocorre, quais suas funções e frequência. Para tanto, nove crianças entre quatro e cinco anos de diferentes nacionalidades e línguas maternas em uma escola internacional foram gravadas durante as atividades de Circle Time e Phonics. De acordo com os dados coletados, na análise quantitativa, cada fala foi classificada em fala privada ou fala social com o propósito de descobrir qual criança produziu mais fala privada. Na análise qualitativa havia a necessidade de considerar o ambiente social da crianças para descrever quando a fala privada ocorreu, sua função e frequência. Por exemplo, existem crianças que são expostas a três ou mais línguas estrangeiras ao mesmo tempo em casa e na escola, algumas somente falam em inglês na escola e português em casa e outras falam inglês e português na escola e em casa. Os resultados mostraram que a fala privada foi importante na promoção da autorregulação durante o processo de ensino-aprendizagem das crianças analisadas. Ela desempenhou um papel importante no engajamento das crianças quando estavam aprendendo os sons e as palavras na língua inglesa. Além disso, a fala privada demonstrou uma participação efetiva das crianças durante as atividades mesmo aparentemente não sendo ouvidas pelo professor.

Private speech, according to Wertsch (1980), is defined as a private dialog that the individual promotes with himself and its function lies in the necessity of self-regulation, self-guidance and self-reflection. Private speech of children and adults has been extensively studied by McCafferty (1994), Berk & Spuhl (1995), Fernyhough & Russell (1997), Krafft & Berk (1998), Winsler, Carlton, Barry (2000), Manfra & Winsler (2006), Smith (2007), Day & Smith (2013) and others. In Brazilian research, a gap could be identified regarding the study of private speech in English as a Foreign Langague for Children (LEC) as an important cognitive tool for the teaching-learning process. In these Brazilian studies, language is considered only a source for communication. The purpose of this study was to verify how…

▼ ENGLISH ABSTRACT: The value of concentrating solar power (CSP) plants lies in dispatchability, which is provided through an integrated cost-effective thermal energy storage system (TESS). Compared to current state of the art molten salt thermal energy storage systems, a rock bed thermal energy storage system has the potential to reduce both the capital costs and Levelized Cost of Electricity (LCOE) significantly. The Stellenbosch University (SU) first-generation rock bed thermal energy storage design served as a proof of concept while the second-generation rock bed design was designed for significant cost reduction. This work presents the third-generation rock bed TESS at SU, through partial re-design, predominantly aiming at maximizing the usable rock mass. The rock bed thermal energy storage system is charged by air at a temperature of 650 C. An existing experimental facility, based on the second-generation design, has recently been constructed. To modify the facility, a concept was developed with knowledge gathered from both the first and second-generation concepts. The new concept charges the rock bed from the top downwards, with a predicted near-linear thermocline progression, where the thermocline is defined as the transition layer from the high temperature to the low temperature within the rock bed. Although the concept has a higher capital cost, an improved performance is predicted for the entire system. After development, the concept was adapted to the existing facility. Three experimental test campaigns were conducted, concluding with a multiple cycle test. This test consisted of three charge-discharge cycles, where the rock bed was discharged to a minimum outlet temperature of 327 C. Determining an accurate discharge mass flow rate was a challenge throughout testing, with flow leakages detected within the system. A flow loss assumption of 40 % was made after several cold air flow rates were tested. The second cycle within the multiple cycle test yielded a heating capacity of 336.67 kWhth, a volumetric efficiency of 60.30 % and a thermal efficiency of 92.40 %. An overall efficiency of 94.24 % was achieved over the three cycles. An analytical model was developed to be validated by the experimental results. From the validation, a possible prediction can be made on the performance of such a rock bed thermal energy storage system on an industrial scale. The thermal efficiency comparison yielded a maximum difference between the experimental and analytical results of +8.00 % for the first two cycles and +19.36 % for the third cycle. It is clear from this comparison that the model over-predicts the performance of the facility. Considering that the model is one dimensional and that it disregards both radiation and convection as heat transfer elements, as well as thermal losses, the model appears to be acceptable. However, it is recommended that further improvements be made to the model for a more accurate comparison. The overall results show that there has been an… Advisors/Committee Members: Von Backstrom, Theo, Lubkoll, Matti, Dinter, Frank, Laubscher, Henk, Stellenbosch University. Faculty of Engineering.

▼ Organic semiconducting materials have received a lot of attention in recent years and can now be found in many applications. One of the applications, the light emitting electrochemical cell (LEC) has emerged due to its flat and lightweight device structure, low operating voltage, and possibility to be fully solution processed. Today LECs can emit light of various colors, but to be applicable in the lighting industry, white light need to be produced in an efficient way. White light on the other hand, is one of the toughest "colors" to achieve in an efficient way, and is of particular interest in general lighting applications, where high color-rendering index devices are necessary. In this thesis I show that blue light can be partially converted, into white light, by utilizing the photoluminescence of color conversion layers (CCLs). Furthermore, I show that a high color-quality white light can be attained by adopting a blue-emitting LEC with a CCL. Particularly, three different color-conversion materials were embedded onto a blue bottom-emitting LEC, to study the resulting spectrum. One of the materials, MEH-PPV, have good absorption compatibility with the electroluminescence of the blue emitters, but the materials photoluminescence do not cover the red to deep-red range of the spectrum. These parts of the spectrum are necessary to obtain high color rendering indices (≥80). A single layer of MEH-PPV adapted onto a blue-emitting LEC, led to a cold white LEC with CIE-coordinates x = 0.29, and y = 0.36, color-rendering index = 71, and correlated color temperature = 7200 K. These properties makes it potentially useful in outdoor-lighting applications. The photoluminescence of another studied color-converting material, polymer red, covers the red to deep-red range of the spectrum but the material lacks absorption in the green parts of the blue emitters electroluminescence spectrum. Thus it is necessary to combine it with MEH-PPV to be able to absorb all wavelengths from the blue-emitter and get a broad light-spectrum out of the device. In order to preserve a part of the blue light, a new device configuration was designed. It features a top-emitting blue LEC with a dual-layer CCL which reach an impressive color rendering index = 89 at a correlated color temperature = 6400 K (CIE-coordinates x = 0.31, y = 0.33). The color-rendering index is the highest reported for a white LEC. The absence of UV-, and IR-radiation, together with the high color rendering properties make the white LEC a possible candidate for even the most demanding lighting-applications, such as art galleries, and shop display windows, together with indoor lighting. In this thesis, I show that the CCLs function well. However, for the LECs to be worthy competitors, the efficiency and lifetime of the blue emitter need improvements.

CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior

Um tipo de dispositivo que tem atraído atenção nos últimos anos no campo da Eletrônica Orgânica é as Células Eletroquímicas Emissoras de Luz, mais conhecidas como LECs (ou LEECs), do inglês Light Emitting Electrochemical Cells. Esses dispositivos eletrônicos têm baixa voltagem de operação, fabricação simples e barata, alto desempenho, ligeira independência dos materiais usados como eletrodo ou da espessura de suas camadas emissoras, além de terem a possibilidade de serem fabricados sobre substratos flexíveis. Por essas razões, as LECs têm sido usadas como possíveis substitutas para os já conhecidos OLEDs (Diodos Orgânicos Emissores de Luz), e o estudo de suas propriedades ópticas e elétricas e de seu princípio de funcionamento têm sido foco de trabalho de muitos cientistas. Dentre os modelos conhecidos que propõem descrever o funcionamento das LECs podemos citar três: a Teoria da Difusão, a Teoria da Dopagem Eletroquímica e a Teoria Mista. No primeiro a injeção de portadores na camada ativa seria facilitada pelos compostos iônicos presentes na blenda que a compõe, com posterior movimentação de cargas por difusão e recombinação no centro da camada. No segundo modelo ocorre a formação de três regiões dentro da blenda polimérica: uma região dopada do tipo p, uma região dopada do tipo n e uma camada isolante onde ocorre a recombinação de cargas para emissão de luz. A teoria mista assume que ambas são possíveis dependendo das condições em que se encontra o dispositivo. A fim de compreender como esses processos ocorrem e interferem no desempenho desses dispositivos propusemos diversas experiências alterando parâmetros importantes na sua fabricação. É proposto um modelo para a influência do tipo de cátion e ânion usado no sal presente na camada ativa e para descrever a influência da concentração desse sal na blenda polimérica que a compõe. Com base nas teorias descritas é colocada em evidência a influência da concentração de polímero transportador de íons na camada emissora e da espessura desta camada. Ao fim de todo o estudo obtivemos um dispositivo otimizado que é comparado com um dispositivo feito com um material novo sintetizado por colaboradores do departamento de Química da UFJF a fim de gerar expectativas para futuros trabalhos.

One type of device that has attracted attention in recent years in the field of Organic Electronics are the Light Emitting Electrochemical Cells, better known as LECs (or LEECs) These electronic devices have low operating voltage, simple and inexpensive manufacture, high-performance, light independence of the material used as electrode or the thickness of its emissive layer, besides having the possibility to be manufactured on flexible substrates. For these reasons the LECs have been used as possible substitutes for known OLEDs (Organic Light Emitting Diodes), and the study of their optical and electrical properties, and its operating principle have been working focus of many scientists. Among the known models proposed…

▼ The purpose of this study is to assess the effectiveness of information, education and communication (lEC) materials as a communication strategy at the Teachers Service Commission (TSC). The TSC has since 1999 embarked on an aggressive campaign to empower its employees. A public relations (PR) section was established to steer communication activities. Acres of materials were produced to disseminate information. However, despite these efforts, complaints about corruption, inefficiency, poor corporate image and insensitivity to customer needs still abound. There seemed to be a disconnect in the communication process between the employer and the employees. The study assesses whether the communication strategies in place have been effective. Four objectives were investigated. These were: the level of awareness of the IEC materials amongst TSC employees; their impact on the employees; the appropriateness of their content; the channels used and the prevailing feedback mechanisms. The study was conducted using an exploratory survey. The participants were TSC employees sampled from Nairobi and Meru districts. A total of 250 employees were selected through stratified and random sampling techniques. Data were collected through a self- administered questionnaire and a total of 199 questionnaires were returned. The study established that although TSC has used multifaceted corporate communication strategies to inform and empower its employees to realize set goals and objectives, the staff are not aware of most of the strategies introduced after 1999.TSC employees have not been empowered by the information disseminated in terms of giving them motivation, job mobility or satisfaction, in addition to enhancing their perception of a good image of the organization. The study also indicated that feedback mechanisms within TSC communication strategies are poor. On the effectiveness of the channels used, memos/circulars were found to be the most popular with website/Email and suggestion boxes being the most unpopular. TSC employees felt there was need for frequent contacts with their employer. However, the findings indicated that a climate of fear and distrust exists between the employees and their supervisors. Employees are not free to discuss problems and difficulties they have in their job for fear of jeopardizing their positions or having it held against them. In view of these findings, the study recommended that TSC carries out an audit of its communication strategies to identify gaps that require urgent interventions. An aggressive sensitization campaign should be carried out to inform TSC staff of the existence of the various IEC materials and the need to embrace them to realize effective service.

Nesse trabalho temos como objetivo estudar blendas poliméricas, capazes de serem aplicadas em camadas ativas para a Célula Eletroquímica Emissora de Luz (LEC). Os materiais escolhidos para a formação da camada ativa foram os polímeros conjugados: o poli [2-metóxi-5-(2-etilhexiloxi)-p-fenilenovinileno)]- MEH-PPV e o Poli [2-(2',5'-bis(2"-etilhexiloxi)fenil)-1,4-fenilenovinileno]- BEHP-PPV e dois conjuntos de eletrólitos poliméricos: o polióxido de etileno bloco polietileno (PE-b-POE) complexado com o sal inorgânico, o perclorato de lítio (LiClO4)† e o triflato de lítio (LiCF3SO3). Para confeccionar as blendas, foram preparadas soluções dos eletrólitos em acetonitrila e dos polímeros conjugados em THF. As blendas foram preparadas nas concentrações de 6,5%; 7,5% e 8,5% de sal. Essa faixa de concentração optimiza às propriedades estruturais e elétricas do EPs e com isso podemos sugerir um dispositivo eletro-óptico. As análises dos resultados mostram que as propriedades ópticas de absorção e emissão das blendas com o BEHP-PPV as modificações mais relevantes com a presença do EP do que no sistema com o MEH-PPV. Já na análise vibracional notamos que somente nas blendas com o BEHP-PPV foi possível identificar os modos vibracionais referentes aos sais dissociados nos EPs. Nas medidas de superfície nota-se uma forte agregação em ambos os PC, de forma que o solvente interage fracamente com essa classe de polímeros, nas blendas confirmamos com a ajuda do AFM a separação de fase. Por fim, das medidas de I x V observamos que a blenda BEHP-PPV com 8,5% de sal LiClO4, possui maior corrente. Efeito de resistência negativa também foi observado para as blendas, que poder ser atribudo por modificações nas propriedades na estrutura de banda do PC.

In this work polymer blends were studied, which were capable of being the active layer in Light Emitting Cell (L.E.C.). The materials chosen for the formation of the active layer were the poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene]- MEH-PPV and the Poli(2,5-bis(2'-ethyl-hexyl)-1,4-phenylenevinylene]- BEHP-PPV and two systems polymer electrolytes, poly (ethylene oxide) block polyethylene (PE-b-POE), complexed with inorganic salts, Lithium Perchlorate (LiClO4) † and Lithium Triflate (LiCF3SO3). To obtain the blends, the solutions of polymer electrolytes were prepared in acetonitrile and the conjugated polymer were prepared in THF. The salt concentration was varied in the range of 6,5%, 7,5% and 8,5%. The results show that the optical properties, absorption and emission, of the BEHP-PPV blends are more modified with the presence of the electrolytes then the MEH-PPV systems. However, in the MEH- PPV blends the vibrational modes of salt dissociated weren’t observed, suggesting high aggregation proven surface measurements. The AFM images help us confirm the phase separation of the blends. IxV curves reveal that BEHP-PPV blend of 8,5% with…

▼ As a means of addressing observed inadequacies in school curricula, the Catholic Special Education and Guidance Service, Brisbane Catholic Education Office in 1980 established a partial withdrawal centre for counsellor-selected gifted children. The Learning Enrichment Centre (L.E.C.) aimed to - 1) meet the needs of enrolled gifted students by - a) providing appropriate learning experiences; and b) providing an administrative arrangement (partial withdrawal) which afforded them the opportunity to interact with like minds; 2) meet the needs of the system by - a) developing and evaluating units of work for gifted students; b) conducting workshops, seminars and in-service days for teachers. In 1984 the L.E.C. curriculum was designed and implemented in accordance with Maker's model of curriculum modification for gifted students (Maker, 1982). This model outlines a set of principles which Maker claims, recognize the characteristics and needs of gifted students and guide the development of a qualitatively different curriculum. In making decisions about design and implementation of Maker's curriculum modifications, factors related to the setting, the teachers and the students were considered. The overall purpose of the Study was to assist teachers in making rational decisions about future L.E.C. provision. In particular the Study was to collect information on the worth of the program - its relative strengths and weaknesses - and the influence on the curriculum of the administrative arrangement. The program was evaluated by ascertaining levels of satisfaction typically expressed by the students. Of secondary concern was whether the organisational arrangement of partial withdrawal had inhibited or enhanced the program's intentions. It was acknowledged that unfavourable attitudes of parents, classroom teachers or peers could conceivably alter students' receptivity of the program. In Term 4, two parallel questionnaires, one addressing the L.E.C., the other the regular classroom, were administered to the students. By comparing responses on matching items, levels of satisfaction with the L.E.C. curriculum were determined. Selected items on the L.E.C. instrument were further to reveal how students felt about the administrative provision and whether classroom teachers and peers were perceived to be supportive. Subsequent to program completion, a questionnaire was mailed to parents bo ascertain their support for the program by asking them how their child's emotional behaviour had changed as a result of LEC attendance. Also they were to indicate whether they preferred that enrichment occur in the regular classroom or partial withdrawal setting. To confirm the students' impressions of classroom teacher support and interest, parents were requested to comment on their understanding of it. Student responses indicated that they found their LEC…

L’Opacification Capsulaire Postérieure (OCP) est la fibrose de la capsule développée sur la lentille intraoculaire implantée (LIO) suite à la dé-différenciation de cellules épithéliales cristalliniennes (LECs) subissant une transition épithélio-mésenchymateuse (EMT). La littérature a montré que l'incidence de l’OCP est multifactorielle, dont l'âge ou la maladie du patient, la technique de chirurgie, le design et le matériau de la LIO. La comparaison des LIOs en acryliques hydrophiles et hydrophobes montre que les premières ont une OCP plus sévère, médiée par la transition EMT. En outre, il est également démontré que l'adhérence des LECs est favorisée sur des matériaux hydrophobes par rapport à ceux hydrophiles. Une stratégie biomimétique destinée à promouvoir l’adhérence des LECs sans dé-différenciation en vue de réduire le risque de développement de l’OCP est proposée. Dans cette étude, les peptides RGD, ainsi que les méthodes de greffage et de quantification sur un polymère acrylique hydrophile ont été étudiés. La surface fonctionnalisée des LIOs favorisant l'adhérence des LECs via les récepteurs de type intégrine peut être utilisée pour reconstituer la structure capsule-LEC-LIO en sandwich, ce qui est considéré dans la littérature comme un moyen de limiter la formation de l‘OCP. Les résultats montrent que le biomatériau innovant améliore l'adhérence des LEC, et présente également les propriétés optiques (transmission de la lumière , banc optique) similaires et mécaniques (force haptique de compression, force d'injection de la LIO) comparables à la matière de départ. En outre, par rapport au matériau hydrophobe IOL, ce biomatériau bioactif présente des capacités similaires vis à vis de l’adhérence des LECs, le maintien de la morphologie, et l'expression de biomarqueurs de l’EMT. Les essais in vitro suggèrent que ce biomatériau a le potentiel de réduire certains facteurs de risque de développement de l’OCP.

Posterior Capsular Opacification (PCO) is the capsule fibrosis developed onto the implanted IntraOcular Lens (IOL) by the de-differentiation of Lens Epithelial Cells (LEC) undergoing Epithelial-Mesenchymal Transition (EMT). Literature has shown that the incidence of PCO is multifactorial including patient’s age or disease, surgical technique, and IOL design and material. Reports comparing hydrophilic and hydrophobic acrylic IOLs show the former has more severe PCO after EMT transition. Additionally, the LEC adhesion is favored onto the hydrophobic materials compared to the hydrophilic ones. A biomimetic strategy to promote LEC adhesion without de-differentiation to reduce PCO development risk is proposed. RGD peptides, as well as their grafting and quantification methods on a hydrophilic acrylic polymer were investigated. The surface functionalized IOL promoting LEC adhesion via integrin receptors can be used to reconstitute the capsule-LEC-IOL sandwich structure, which is considered to prevent PCO formation in literature. The results show the innovative biomaterial improves LEC adhesion, and also exhibits…

Wie in vorausgehenden Studien beschrieben wurde, ist Brustkrebsmetastasierung abhängig von der Aktivität von Lipoxigenasen, welche 12(S)-HETE generieren. 12(S)-HETE wird von MCF-7 Tumorzellspheroiden produziert und freigesetzt und induziert dabei eine Spaltformation in Lymphendothelzell Monolayers. Ein 3D Ko-Kultur System imitiert das Eindringen von Brustkrebszellen in das lymphatische Gefäßsystem und fasst den Mechanismus der Metastasierung zusammen. In dieser Arbeit untersuchten wir einen spezifischen 12/15 Lipoxigenase Hemmer, Baicalein, und das strukturell gleich gebaute Wogonin um Spaltformationen zu hemmen. Neben 12(S)-HETE haben wir auch NF-ĸB als wichtigen Mitwirkenden in der Spalformation identifiziert. Demzufolge testeten wir Verbindungen wie Di-galloyl-resveratrol, Resveratrol und Gallussäure sowie deren Derivate mit vermeintlicher Hemmwirkung von NF-ĸB in diesem 3D Metastasierungs Ko-Kultur Model. Unter den synthetischen Drogen untersuchten wir auch natürlich vorkommende Substanzen, wie Hyperforin, welches ein Hauptbestandteil von Hypericum perforatum ist. Die Aktivierung von NF-ĸB ist verbunden mit Zellproliferation, Zellüberleben, Zelleindringen und Angiogenese. Dies macht NF-ĸB zu einem interessanten Ziel in der Krebsbekämpfung. Wir untersuchten einen irreversiblen Hemmer von NF-ĸB – Bay11-7082. Aufgrund der Hemmwirkung von Bay11-7082 in der Spaltformation untersuchten wir die NF-ĸB vermittelte Lymphendothelzellbewegung, welche die ZEB-1 abhängige Expression von VE-cadherin und die Anhaftung von Tumorzellen an Endothelzellen miteinbezogen hat. Die Anhaftung von Tumorzellen an das Endothelium stellt den ersten Schritt der Metastasierung dar. Wir beschrieben die mögliche Rolle von drei NF-ĸB regulierten Ligand – Rezeptor Pärchen in Tumorzelladhesion an das Endothelium, ICAM-1/αLβ2, CD31/ αVβ3 und E-selectin/ CD44.

Ductual breast cancer metastasis depends on the expression and activity of lipoxygenases, which generate 12(S)-HETE. 12(S)-HETE is produced and released by MCF-7 tumor cell spheroids and induces gaps in a LEC monolayer. A 3D co-culture system mimics the invading of breast cancer cells to the lymphatic vasculature and recapitulates the mechanisms of metastasis. In this work I investigated a specific inhibitor of 12/15-Lipoxygenase, Baicalein, and the structurally highly related Wogonin on inhibition of gap formation. Besides 12(S)-HETE, we could identify also NF-ĸB as a major player in MCF-7/LEC gap formation. Therefore, we tested compounds, such as Di-galloyl-resveratrol, Resveratrol and Gallic acid and their derivatives, with putative NF-ĸB inhibitory properties in this 3D metastasis co-culture model. Among the synthetic drugs we also studied natural compounds, such as Hyperforin, a main constituent of Hypericum perforatum. NF-ĸB activation is associated with tumor cell proliferation, survival, invasion and angiogenesis. This makes NF-ĸB an interesting target for the treatment of cancer. We investigated an irreversibly inhibitor of NF-ĸB – Bay11-7082. Due to the Bay11-7082…

En tant que syntagmes sémantiquement non-compositionnels, les locutions sont des unités lexicales à part entière, qui doivent avoir leur propre entrée dans un modèle du lexique. Elles doivent donc recevoir une définition lexicographique, ainsi qu’une description de leurscaractéristiques grammaticales. De plus, en vertu de leur signifiant syntagmatique, les locutionstémoignent – à des degrés divers – d’une flexibilité formelle (passivation, insertion de modificateurs, substitution de certains constituants, etc.).Notre thèse défend l’idée selon laquelle une description des locutions combinant à la fois l’identification des unités lexicales qui les composent et l’identification des relations de dépendance syntaxique qui unissent les unités constituantes, permettra de prédire leurs différents emplois possibles dans la phrase. Une telle description n’est possible que dans un modèle du lexique décrivant précisément la combinatoire des lexies. Notre recherche, basée sur les principes de la Lexicologie Explicative et Combinatoire, exploite et enrichit les données du Réseau Lexical du Français (RL-fr), ressource en cours de développement à l’ATILF.La thèse a deux principaux apports. Le premier est le développement d’un modèle de description lexico-syntaxique relativement fine des locutions du français. Le second est l’identification et l’étude de différentes variations structurales, syntaxiques et lexicales liées à la flexibilité formelle des locutions. Les variations des locutions sont mises en corrélation avec leurs structures lexico-syntaxiques, mais également avec leurs définitions lexicographiques. Ceci nous conduit à introduire la notion de projection structurale, centrale dans le continuum de la flexibilité formelle des locutions

As semantically non-compositional phrases, idioms are lexical units. Consequently, they must have their own entries in a lexical resource, with a lexicographic definition and grammatical characteristics. Furthermore, because of their phrasal signifier, idioms show – to varying degrees – a formal flexibility (passivization, attachment of modifiers, substitution of components,etc.)Our thesis defends the view that a description of idioms that combine identification of their lexical components and identification of dependency links between these components will permit to predict their formal variations. Such a description is possible only in a model of lexicon that describes precisely combinatorial proprieties of lexical units. Our thesis, based on the Explanatory Combinatorial Lexicology’s framework, exploits and enhances the data of the French Lexical Network (fr-LN). This resource is being developed at the laboratory ATILF (Nancy, France).The thesis makes two principal contributions to the study of phraseology. The first contribution is the development of a precise description of idioms’ lexico-syntactic structures. The second contribution is the indentification and the study of structural, syntactic and lexical variations linked to idioms’ formal flexibility. Idioms’ formal variations are…

▼ In perfect harmony with the "Year of Light (IYL 2015)", the thesis has been entirely centered on the concept of Light involving the development of transition metal complexes for both the conversion of light into electric energy through dye-sensitized solar cells and, conversely, the production of light starting from electricity by fabrication of electroluminescent devices. The main part of the thesis has been devoted to the sunlight-to-electricity conversion, a target that is well contextualized within the global commitment for the progressive increase of the percentage of electric energy produced by renewable resources. In this context dye-sensitized solar cells, DSSCs, are promising devices alternative to the well established technology of silicon photovoltaics for energy production from the abundant solar light. DSSCs are devices able to harvest solar light and convert it into electricity employing a sensitizer (adsorbed on a semiconductor) and a redox couple properly chosen and combined. The project have concerned the design, synthesis and characterization of both sensitizers and redox mediators constituted by ruthenium and copper-based complexes respectively, together with their final assembly into laboratory-type DSSCs to evaluate their performance. In this way an all-round study has been carried out, from molecules on paper to test benches, passing through laboratory counters. The second, minor part, of the thesis has been focused on the diametrically opposed task, the generation of light. In this context some luminescent heteroleptic complexes based on the cheap and quite abundant copper element have been proposed. The final aim has been the synthesis of efficient luminophores for fabrication of devices able to generate light applying an electric potential across two electrodes such as in organic light-emitting diodes, OLEDs, or in analogue light-emitting electrochemical cells, LECs. The light production in LED-type devices is very efficient especially compared with other traditional artificial light sources like incandescent or fluorescent lamps, and so in line with the international policy of reducing energy consumption. In conclusion the thesis project can be schematically depicted as a circular pathway that joints together two opposite but strictly interconnected concepts (i.e. light and electricity) mutually corresponding to the task and the mean, the start and the end.

▼ Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. These nanopatterned polymer films can be used in a wide variety of scientific fields, not the least the organic semiconductor industry. There the nanopatterned films have, among else, been used to improve the efficiency of organic light-emitting diodes (OLEDs). The light-emitting electrochemical cell (LEC), which is similar in structure to an OLED, also uses polymer films in their device structure but the light emitting layer also contains an electrolyte. However, it has not been shown if nanopatterns can improve LECs as well or if it is even possible to make an imprint in their polymer films that are mixed with an electrolyte. This thesis shows that T-NIL can be used to imprint nanopatterns in films made of poly(ethylene oxide) and the conjugated polymer Super Yellow. The best nanopatterns were produced by setting the imprint parameters to 85 °C, 10 bar, 1800 s for poly(ethylene oxide) and 115 °C, 20 bar, 1800 s for Super Yellow. Imprints were also performed on polystyrene but no nanopatterns could be produced. This was most likely because the stamp could not handle the high temperature that is required to make a nanopattern in polystyrene. The best imprint parameters of Super Yellow were then used to produce a pattern in a film made of Super Yellow mixed with the salt tetrahexylammonium tetrafluoroborate (THABF₄) in order to be able to produce one imprinted and one reference LEC. The imprinted LEC had a luminosity of 139 cd/m², an improvement of 20% compared to the reference’s 115 cd/m² when operated under identical conditions. The forward direction and the angular dependent electroluminescence spectrum of the imprinted LEC clearly showed an effect not observed in the reference. These findings show that the polymer films used in a LEC can be imprinted with a nanopattern by using T-NIL. The imprinted films can be used to create functional LECs that show different behavior and a higher luminosity compared to a non-imprinted reference. If these results can be repeated it might be the starting point of a brighter future.

▼ Polymer light-emitting electrochemical cells (PLECs) were tested by means of bias stress, luminescent imaging and optical scanning probing. These cells were characterized in terms of the effect of doping on the operational lifetime of the cells, the electronic structure of the pn junctions formed in the cells and the average doping levels in the cells. The lifetime performance of sandwich cells was compared in operation with intermediate storage time and in continuous operation. The cells that were stressed intermittently were more prone to black spots degradation than the cells in continuous operation when the total stress time was the same. However, the black spots vanished in the cells’ idle time, which shows that these spots are local highly doped regions. The appearance of the black spots was strongly associated with the storage of the cell in the presence of the aluminum cathode. The doping in planar PLECs was investigated by optical beam induced current (OBIC) and photoluminescence (PL) scanning using a focused laser beam. Both p-n and p-i-n PLEC junctions were identified and the junction widths were extracted. The widths were as small as 0.21% of the cell size being the smallest width identified for PLECs and light-emitting electrochemical cells (LECs), in general. Exposing the cells to relaxation (de-doping) cycles resulted in shrinkage in the depletion region width, contrary to what is expected. This suggests the presence of submicron structures in the as-activated cells that disappeared after relaxation. In addition, it was observed that relaxation caused a p-i-n junction to emerge from the as-activated p-n junction. The junction doping level was extracted from the OBIC data and was validated via drift diffusion calculations. The calculations showed PLEC doping levels in the range of 10E14 cm^-3 – 10E15 cm^-3 in the junction region. The average doping level in planar PLECs was measured by stress-discharge tests. The measurement offered validation for the used method to estimate PLEC doping levels by integrating the activation charge up to the junction formation. The measurement revealed average doping levels of 10E19 cm^-3 - 10E20 cm^-3, which is much higher than doping levels determined for the junction.

▼ O ensino de Língua Estrangeira para Crianças (LEC) bem como sua pesquisa encontram-se em expansão no Brasil e no mundo (Cameron, 2003; Gimenez 2010). Entre os estudos na área de LEC faltam pesquisas que avaliem e analisem dados que provenham de intervenções do ensino de escrita em LEC para crianças alfabetizadas entre 8 e 10 anos (Figueira, 2010). Com o intuito de contribuir para o ensino da escrita em inglês para o nível fundamental, esta dissertação objetiva demonstrar como uma intervenção pedagógica, realizada com alunos do 5º ano em uma escola particular paulista, ensinou o texto persuasivo em inglês e quais foram as implicações desse ensino para os participantes. Nesta pesquisa de mestrado, a professora-pesquisadora objetivou intervir na compreensão de texto de opinião dos alunos de modo a propiciar a expansão do conhecimento (Daniels, 2011; Magalhães, 2009) e o aprimoramento da escrita deles. Conforme as ações de aprendizagem de Davydov (1988), os alunos responderam à pergunta-problema elaborada para o curso, formularam representações sobre as características da persuasão, analisaram textos biográficos e textos persuasivos e, ao final da intervenção, redigiram textos persuasivos sobre o real inventor do avião. A intervenção pedagógica teve suas bases na Teoria da Atividade Sócio Histórico e Cultural, conforme os teóricos Vygotsky (2007) e Davydov (1988). Para Vygotsky (2007), as funções intelectuais dos seres humanos não são tidas como meros resultados de maturação biológica, como algo natural e inato a todos os seres humanos, pois são construídas socialmente com o auxílio fundamental da linguagem. Isso revela que as funções mentais superiores advêm da interação social, das práticas sociais e da história. Desse modo, a cognição não surge apenas do funcionamento biológico, pois advém da integração do corpo biológico com as práticas sociais (Vygotsky, 2007). Outra base teórica para a intervenção foi a Escola Australiana de Gêneros Textuais. Nessa perspectiva, o gênero textual se materializa no uso da língua, que é um meio pelo qual o ser humano constrói significados em um dado contexto social (Eggins, 2004; Halliday & Matthiessen, 1994; Martin, 2008). Dessa forma, o gênero pode servir como uma ferramenta utilizada para criar Zona de Desenvolvimento Proximal e expandir o conhecimento dos alunos. As perspectivas teóricas adotadas, portanto, objetivaram agir no campo em que atuaram (Lantolf, 2000, 2007; Spinoza, 1998; Vygotsky, 2007). Os resultados obtidos após a realização da intervenção pedagógica apontam para a conscientização dos alunos em relação à função persuasiva dos textos de opinião. Além disso, a análise de dados demonstrou que os alunos melhoraram sua escrita de texto de opinião em relação ao pré-teste, realizado antes da intervenção pedagógica. A conclusão aponta que ainda há muito a ser feito na área do ensino da escrita em língua estrangeira, mas que a criança deve ser sensibilizada a produzir textos de opinião ainda na escola primária (Souza, 2003: 73), uma vez que a argumentação e a persuasão estão… Advisors/Committee Members: Marilia Mendes Ferreira, Raquel Aparecida Marra da Madeira Freitas, Eliane Gouvêa Lousada.
