Nanopartículas de Co suportadas em SiO2: síntese, caracterização e propriedades catalíticas para a reforma a vapor do etanol
(Universidade Federal de São Carlos, 2007-03-16)
Colloidal Co Nanoparticles (Co-NPs) were used to prepare supported Co catalysts. The Co-
NPs were obtained by thermal decomposition of the precursor Co2(CO)8 in the presence of
oleic acid and trioctylphosphine oxide ...
Fração de filme líquido nas paredes de um lavador Venturi
(Universidade Federal de São Carlos, 2008-07-10)
The study of the liquid film in the walls of a Venturi scrubber was chosen as the target of this work for representing one of the important phenomena that influence the collection efficiency of the equipment. Such efficiency ...
Aplicação de técnicas de análise de imagens na quantificação da concentração celular no cultivo de células de inseto.
(Universidade Federal de São Carlos, 2004-04-26)
Paradoxally, in spite of the cellular concentration to be the most important variable
in a bioprocess, in practice is the less monitored as a consequence of the experimental
difficulty found in its quantification in an ...
Hidrotalcitas de Ni-Mg-Al como precursores de catalisadores para produção de gás de síntese a partir de biogás
