1. Avaliação do tratamento tópico de lesões cutâneas com filmes obtidos do polissacarídeo da goma do cajueiro (Anacardium occidentale L .)
Os efeitos do tratamento do filme polimérico preparado com o polissacarídeo extraído da goma do Anacardium occidentale L. foram avaliados em lesões cutâneas excisionais em camundongos albino Swiss, através do acompanhamento da evolução do processo cicatricial cutâneo, sob os aspectos clínicos e histopatológicos. Após a realização do procediment

2. CARACTERIZAÇÃO DO ESCOAMENTO DE LÍQUIDOS VISCOELÁSTICOS NO PROCESSO DE REVESTIMENTO POR ROTAÇÃO DIRETA / FILM - SPLITTING FLOWS OF VISCOELASTIC LIQUIDS VISUALIZATION
Roll coating is a common method in the manufacture of a wide variety of products. It is used to apply a thin liquid layer to a continuous flexible substrate. At low speeds, the flow is two-dimensional and steady; as the roll speed is raised, the two-dimensional flow is unstable and is replaced by a steady three-dimensional flow, which results in more or less

3. Interações entre bicamadas lipídicas e interfaces hidrofóbicas / Interactions between lipid bilayers and hydrophobic interfaces
Determinations of surface tension (γ) at the air--water interface, contact angles (Θ), and in and ex-situ ellipsometric mean thickness (d) were used to study the interaction between dioctadecyldimethylammonium bromide (DODAB) small vesicles and spin-coated polystyrene sulfate (PSS) films on silicon wafers. Upon the adition of NaCl (50 mM final conc

4. Effect of mechanical deformation on ionic transport in polimeric films. / Efeito da deformação mecânica no transporte iônico em filmes poliméricos.
Recently a piezoelectric effect was found when a polymeric film, separating two electrolyte solutions at different concentrations, was deformed. This effect was attributed to the modulation of the mobility of the íons in the polymer. It was observed that the effect decreases as the electrolyte concentrations increases. In order to understand more deeply thi
