Síntese de celulose bacteriana a partir de resíduos lignocelulósicos via evolução adaptativa
(Universidade Federal de São Carlos, 2019-05-21)
Bacterial cellulose (BC) is produced mainly by the Komagataeibacter genus. BC is a biopolymer free of impurities, built from the interlacing of cellulose nanofibers, which presents remarkable properties, such as: high ...
Influência das cargas eletrostáticas na filtração de partículas em meios filtrantes de fibra de vidro
(Universidade Federal de São Carlos, 2019-04-30)
Currently, in the gas filtration processes, the presence of electrostatic charges in the particles has been shown to contribute positively to the performance of the filter medium. Due to its high competitiveness in the ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
