  Propriedades dielétricas de cristais líquidos confinados: fases moduladas, Descrição: Como objetivo geral deste projeto, queremos estudar as propriedades dielétricas de fases líquido cristalinas moduladas, principalmente as fases colestéricas e a fase nemática twist-bend. Para tal, pretendemos utilizar a técnica de espectroscopia de impedância, modelos analíticos e computacionais para a interpretação dos dados. De forma mais especifica, pretendemos, como técnica experimental, utilizar a técnica de espectroscopia de impedância e outras técnicas auxiliares, a serem feitas com os recursos adquiridos neste edital. Como estas fases moduladas apresentam diversas texturas, queremos entender o efeito da modulação e da morfologia no processo de difusão iônica além de vários outros efeitos relacionados. Do ponto de vista teórico, queremos utilizar a modelagem tipo PNP, PNPA, elasticidade de Frank, modelos de Landau-DeGennes e novas abordagens elásticas para a fase TB para alcançarmos tais objetivos.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Mestrado acadêmico: (1) / Doutorado: (1) . , Integrantes: Rafael Soares Zola - Coordenador / Evangelista, L.

  Propriedades eletro-ópticas e de interfaces em cristais líquidos nemáticos quirais para aplicações em displays, Descrição: A fase liquido cristalina nemática quiral, também conhecida como colestérica tem grande potencial para aplicações tecnológicas,como displays. Embora o Brasil tenha diversos grupos que se dediquem a estudar cristais líquidos, poucos se empenham no desenvolvimento de displays, focando exclusivamente a física básica de cristais líquidos. Além do mais, entre todos estes grupos, pouquíssimos se dedicam a estudar a fase nemática quiral, conhecida por suas particularidades e grande potencial para ser usada em displays. Isso porque a fase reflete luz em determinados comprimentos de onda que podem ser controlados, além de ser biestável, ou seja, apresenta dois estados opticamente diferentes quando o campo elétrico é desligado. Portanto, o projeto que estamos propondo é de vanguarda no País. O projeto contará com pesquisadores com grande experiência internacional no desenvolvimento de dispositivos eletro-ópticos. Mais especificamente, dois dos participantes deste projeto possuem a patente para um display refletivo com colestérico no chamado modo de Helfrich ou dual-modo. Naturalmente, além do estudo e firmamento do Brasil no ramo de displays refletivos, um dos nossos passos será o de continuar o desenvolvimento deste tipo de display, que necessita de baixa potencia e possui um tempo de resposta rápido. O projeto visará, entre outros, a modelagem para a dinâmica de Helfrich e o estudo de polímeros dispersos e camadas de alinhamento nesta dinâmica.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Mestrado acadêmico: (1) . , Integrantes: Rafael Soares Zola - Coordenador / Lenzi, E.

  Aplicações das Equações de Difusão, Projeto certificado pelo(a) coordenador(a) Ervin Kaminski Lenzi em 26/11/2012., Descrição: Descrição: As equações de difusão e suas extensões têm atraído a atenção de vários pesquisadores devido ao grande número de aplicações nos diversos campos da ciência, e, de modo particular, em vista das aplicações associadas à difusão anômala. Inserido nesse contexto geral, este projeto prevê a investigação de soluções para as equações de difusão e demais situações físicas que podem ser relacionadas a elas, como por exemplo, o problema de reorientação molecular em cristais líquidos nemáticos sob a ação de campos externos, a dinâmica do processo de adsorção iônica ou de partículas neutras em cristais líquidos e, também, a difusão fracionária em conexão com os resultados de espectroscopia de impedância em líquidos e fluidos complexos. Outra vertente a ser explorada envolve a equação de Schrödinger com derivadas de ordem fracionárias, termos de natureza não local ou com a massa dependente da posição. Esses problemas encontram possíveis aplicações a sistemas de natureza física como os vidros e materiais amorfos, quando levamos em conta a estatística quântica que emerge dessa abordagem..

  Liquid Crystal wetting of a thin coated polyimide layer, Descrição: The interfacial problem of wetting is studied experimentally, by simulation and theory. Near the Isotropic-Nematic liquid crsytal (LC) transition, the highly hidrophobic, rubbed surface enhances the order parameter. Under a wetting transition, the contact angle between liquid crystal and the surface becomes zero, a phenomena driven by the competition among the surfacial energies envolved in the problem. In the thin wetting layer (~1um), many rich physical phenomena appear, such as the orientation of the LC on the isotropic phase, ionic effect (Debye length) due to the adsorbed ions and polarization effects. Of particular interest, cholesteric samples have finger print formation, probably due the interplay of ionic effect and orientation LC-Isotropic. Additionally to confical, POM, and atomic force microscopy, we propose a Landau model for the wetting and a relaxation method describing the finger print state. Optical methods such as 4X4 and Jones methods are used for the texture simulation.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Rafael Soares Zola - Coordenador / Yang, D.-K - Integrante / Young-Cheol Yang. - Integrante.

  Development of a Cholesteric Display Under Active Matrix (TFT) DIslpays., Descrição: Current used displays take advantage of TFT (Active Matrix) driving, which are addresed in a much fast way than passive matrix displays. Cholesteric displays under passive matrix is a mature technology but it is impossible to show 60Hz video ratio due to the slow refreshing ratio and and slow response of the cholesteric material. We successfully design a new driving scheme for TFT cells, and simulated TFT behavior using a reed relay. The response time issue is overcome by using new, small molecule materials capable of reducing rotational viscosity, and seeds on the walls.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Rafael Soares Zola - Coordenador / Yang, D.-K - Integrante / Young-Cheol Yang. - Integrante.

  Buckling of a Membrane with Nematic Order, Descrição: The buckling of membranes with liquid crystal symmetry is a well known problem in physics and in biology. Works like the one done by Linda Hirst from California University show that the fast cooling of a lipid membrane may crumple it, possible because of the liquid crystalline order. In this work, we investigate theoretically the role of defects in the director field to the buckling of the membrane. Based on works like David Nelson et al., we show that simple +1 defects in a membrane with liquid crystalline order is enough to bend it.. We also study the minimal possible configuration and numerical solutions of the problem.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Rafael Soares Zola - Integrante / Selinger, Jonathan - Coordenador.

  FOURIER OPTICS WITH SPATIAL LIGHT MODULATORS, Descrição: The objective of this work is to study Fourier Optics by using Spatial Light Modulators (SLMs) as the input image and filter on the fourier plane. A work like this can be supported by the fact that the SLMs allow real time time and easy manipulation for high resolution images and, at same time, saves a lot of computation time when compared with numerical analyzes of high resolutions images. We designed our own setup with two spatial light modulators, one transmissive and and one reflective. With this kind of work we could deal with medical images processing to recognize breast cancer and other kinds of applications.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Rafael Soares Zola - Integrante / Muhoray, Peter Palffy - Coordenador.
