1. Química supramolecular de fármacos antirretrovirais inibidores nucleosídeos de transcriptase reversa: novas formas cristalinas e alteração de propriedades de estado sólido / Supramolecular chemistry of antiretroviral nucleoside reverse transcriptase inhibitor drugs
Solid state properties are directly related to drug performance. Among all physical and chemical properties dependent on the crystal phase of a drug, stability and solubility are the main ones that alter its bioavailability. In this way, molecular crystal engineering is a strategy to improve solid state properties of drugs related to their efficacies. In thi

2. Fabricação e caracterização de dispositivos poliméricos emissores de luz com camada ativa de poli(2-metóxi, 5-(2-etil-hexilóxi)-1,4-fenileno vinileno) (MEH-PPV) / Fabrication and characterization of polymer light-emitting diodes with active layer composed by poly(2-methoxy, 5-(2-etil-hexilhoxy)-1,4-phenilene vinilene) (MEH-PPV).
Polymer light emitting diodes (PLEDs) have been widely investigated as candidate materials for display fabrication. The main advantages exhibited by PLEDs are the low-cost processing and possibility of large-area display fabrication, in comparison to the conventional liquid crystal displays (LCDs). Although the engineering aspects concerning device fabricati

3. Propriedades elétricas e físico-químicos de blendas de poli (sulfeto de p-fenileno) - pps com um cristal líquido polimérico (LCP) / Electrical and physical chemistry properties of poli (p-phenylene sulfide) with a liquid crystal polymer
Poly (p-phenylene sulphide) (PPS) is an engineering thermoplastic, with high thermal and chemical resistance, and. with a growing industrial importance, due to its easy processability in the form of films, fiaments and injection molded articles. It also can be chemically doped and. therefore be a conductive polymer (σ = 10 S/cm, by doping with AsF5); ho

4. Prediction of disclinations in nematic elastomers
We present a theory for uniaxial nematic elastomers with variable asphericity. As an application of the theory, we consider the time-independent, isochoric extension of a right circular cylinder. Numerical solutions to the resulting differential equation are obtained for a range of extensions. For sufficiently large extensions, there exists an isotropic
