1. Investigation about the copper adsorption on the chloropropylsilica gel surface modified with a nanostructured dendrimer DAB-Am-16: an analytical application for determination of copper in different samples
The third generation (G-3) poly(propyleneimine)hexadecaamine dendrimer (DAB-Am-16) was grafted onto the chloropropylsilica gel surface (DPPIPS). The modified silica (DPPIPS) was characterized by Electronic (Uv-Vis), vibrational and Electron Paramagnetic Resonance (EPR), spectrocopies, surface area (331.07 m².g-1) and porosity analyses (pore diameter of 41.9

2. "Resistência à Corrosão de Aços Inoxidáveis em Solução Sintética de Condensado de Álcool Combustível / "Resistência à Corrosão de Aços Inoxidáveis em Solução Sintética de Condensado de Álcool Combustível
Nowadays a great effort had been directed to research work in order to attend the environmental protection agencies demands for minimizing the levels of gases emission pollutants. The consumers requirements for more economic and durable vehicles had motivated also the researchers to look for more corrosion resistance materials in order to substitute the trad

3. Processamento Coloidal de Cromito de Lantânio / LANTHANUM CHROMITE COLLOIDAL PROCESSING
Lanthanum chromite (LaCrO3) is currently the most studied material for applications such as solid oxide fuel cell interconnector (HTSOFC). The complexity of microstructures and geometries of HTSOFC devices, require a precise control of processing parameters to get the desired combination of properties and this, the use of techniques involving concentrated ce

4. Análise de desempenho de um motor ciclo Otto alimentado com álcool de 75 INPM / Otto cycle engine performance working with low alcohol content ethanol
Motor a álcool teve grande aplicação no Brasil com a implantação do Proálcool, programa lançada na década de 1970, vislumbrando reduzir a dependência externa do petróleo. Ressalta-se que avanços na tecnologia do referido motor, bem como na produção de álcool, tornaram-no técnica e economicamente viável como substituto da gasolina em algumas r

5. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom

6. Estudo do Catalisador (10%Ni-1%Cu) suportado na oxidação parcial indireta do Etanol
In the present work, the reaction of indirect partial oxidation of the ethanol for production of H2 for fuel cells was studied in catalysts 10%Ni-1%Cu (% mass) on different supports (Al2O3, SiO2-50, SiO2-200, Nb2O5 and CeZrO2). The catalysts were prepared by coimpregnation, leaving from aqueous solution of the respective nitrates, dry and calcined. The oxide
