1. Performance eletrocatalítica frente a nitrito de um filme híbrido de fosfomolibdato e sílica organomodificada
RESUMO Materiais híbridos orgânico-inorgânicos nanoestruturados são produzidos com a finalidade de desenvolver e/ou aprimorar uma propriedade de interesse. Uma forma de obtenção de materiais híbridos é através da imobilização de um componente inorgânico em uma rede de sílica organicamente modificada (ormosil). Neste trabalho, um polioxometalato

2. Obtenção e caracterização de revestimentos híbridos à base de precursores alcoóxidos sobre o aço galvanizado
Galvanized steel presents a protective layer of Zn and Zn-Fe, obtained by hot dipping, which promotes the steel protection. However, the presence of this layer decreases the adhesion of paint systems and reduces the corrosion resistance. A very efficient method used to protect against the substrate corrosion is chromate layers, which provide excellent antico

3. Estudo atomístico da formação de interfaces orgânico-inorgânico: Tiofenos sobre óxido de titânio / Atomistic study of the formation of organic-inogarnic interfaces: thiophenes over titanium oxide
No estudo de sistemas híbridos orgânico-inorgânico, o uso de materiais como polímeros conjugados e óxidos de metal de transição tem despertado grande interes- se. Em particular, destacam-se sistemas compostos de tiofenos e óxido de titânio, que encontram uma importante aplicação em células solares. Para um melhor entendimento da interação entre

4. Characterization of organic-inorganic hybrid coatings for corrosion protection of galvanized steel and electroplated ZnFe steel
The development of hybrids materials has been extensively investigated in recent years. The combination of a wide variety of compositions and production processes had permitted the use of these materials in different applications like coatings for corrosion protection of metals. In this work organic-inorganic hybrid materials have been prepared from the hydr

5. Filmes híbridos orgânico-inorgânicos a partir de óleo de soja funcionalizado
Organic-inorganic hybrids materials can be prepared by the sol-gel process and have applications in biomaterials, catalysis, optics, membranes, chromatography, electrochemistry and coatings. Vegetable oils can be used as organic component for the preparation of these materials and, as they are biodegradable and obtained from natural and renewable sources, th

6. Síntese, caracterização e atividade catalítica de novos catalisadores metaloporfirínicos suportados / Synthesis, characterization and catalytic activity of novel anchored metalloporphyrin catalysts
In this work the second generation metalloporphyrin Me(TFPP)Cl (Me = Fe and Mn) [5,10, 15, 20 ? tetrakis(pentafluorophenyl) porphyrin iron (III) or manganese (III) chloride] was covalently anchored to aminofunctionalyzed supports, through nucleophilic substituition of the para-fluorine atoms of the pentafluorophenyl meso-aryl groups, with the objective of ob

7. Synchrotron SAXS Studies of Nanostructured Materials and Colloidal Solutions: A Review
Structural characterisations using the SAXS technique in a number of nanoheterogeneous materials and liquid solutions are reviewed. The studied systems are protein (lysozyme)/water solutions, colloidal ZnO particles/water sols, nanoporous NiO-based xerogels, hybrid organic-inorganic siloxane-PEG and PPG nanocomposites and PbTe semiconductor nanocrystals embe

8. Obtenção e caracterização de materiais hibridos organo-inorganicos a base de silsesquioxanos em ponte
In this work, organic-inorganic hybrid materiaIs were prepared through an organic component and an alkoxysilane properly functionalized, by the sol-gel process, at room temperature. Dibutyltin dilaurate was used as catalyst of the silane s hydrolyze/condensation reactions. These materiaIs were obtained from the stechiometric mixture of epoxy resin poly(bisph
