1. Formación electroquímica de películas de polipirrol sobre Nitinol a partir de soluciones de ácido sulfosuccínico
ABSTRACT In this work the electrosynthesis of polypyrrole (PPy) on Nitinol from solutions of sulfosuccinic acid (0,25 M) and pyrrole (0,25 M) was studied. The PPy was formed potentiostatically in solutions of pH 1 and 7. As far as we know, this is the first time that the electrodeposition of PPy is carried out in the presence of sulfosuccinic acid. The morph

2. Development of a Selective and Sensitive Sensor for Urate Determination Based on Tris(1,10-phenantroline)copper(II) Bis(tetracyanoquinodimethanide) Adsorbed on Carbon Nanotubes
The present work describes the development of a selective electrochemical sensor for urate based on tris(1,10-phenantroline)copper(II) bis(tetracyanoquinodimethanide) (Cu(phen)3(TCNQ)2) adsorbed on multi-walled carbon nanotubes (CNT). The composite material was characterized by infrared spectroscopy, scanning electron microscopy, and electrochemical impedanc

3. Morfologia de imaturos de Lutzomyia (Nyssomyia) intermedia (Lutz &Neiva, 1912) e Lutzomyia (Nyssomyia) neivai (Pinto, 1926) (Diptera: Psychodidae: Phlebotominae) : vetores de Leishmaniose Tegumentar no Brasil / Morphological study of immature forms of Lutzomyia (Nyssomyia) intermedia (Lutz &Neiva, 1912) and Lutzomyia (Nyssomyia) neivai (Pinto, 1926) : (Diptera: Psychodidae: Phlebotominae), vectors of leishmaniasis in Brazil
Os flebotomíneos, vetores das leishmanioses, são identificados e classificados pela morfologia dos insetos adultos, existindo poucos conhecimentos de caracteres das formas imaturas. Das 500 espécies Neotropicais descritas, somente 66 espécies tem suas formas imaturas estudadas. Visando avaliar a importância de alguns caracteres taxonômicos dos estádio

4. Contaminação com sal de cloreto e cromatização da superfície do aço zincado no processo não-contínuo de zincagem por imersão a quente: influência no desempenho de tintas e determinação de pré-tratamentos para pintura adequados. / Chloride salt contamination and chromate quenching of galvanized steel on the batch galvanizing process: the influence on paint performance and the determination of suitable surface preparation for painting.
The batch galvanizing process (BGP) can lead to surface contamination of hot-dip galvanized steel (HDGS) with chloride residues. If these residues are not effectively eliminated, they can influence negatively on the performance of duplex systems (galvanizing plus painting). It is known that the chromate quenching is widely used in the BGP, however the effect

5. Eletrochemical characterization of PSSO3H/Pani composite for fuel cells applications / Caracterização eletroquimica do composito PSSO3H/PAni para aplicação em celulas a combustivel
The development of alternative materials for fuel cells applications consists on a tentative to produce commercially available fuel cells, by reduction of costs with their manufacturing and materials. This master dissertation presents an investigation on the polystyrene sulfonate/polyaniline composite, which is an alternative material with low cost of produc
