Estudo fitoquímico de Conchocarpus marginatus (Rutaceae), e avaliação do potencial biológico dos compostos isolados
(Universidade Federal de São Carlos, 2013-03-27)
The specie Conchocarpus marginatus is native from Espírito Santo. This plant, that was recently reclassified by PIRANI e KALLUNKI, does not show chemical or biological data in literature yet. In this way, the phytochemical ...
Proposta curricular do estado de Minas Gerais: uma análise pela ótica de professores e alunos do ensino médio
(Universidade Federal de São Carlos, 2013-02-28)
When starting the study of Chemistry Basics, we use the knowledge and knowledge that students already have and they often do not relate to chemistry, and promote thus a connection between scientific knowledge and the ...
Reforma a vapor de acetona sobre catalisadores de Ni e Co/MgAl2O4: efeito das propriedades redox dos reagentes e dos catalisadores nos caminhos de reação
(Universidade Federal de São Carlos, 2014-12-12)
The Steam reforming of Acetone (SRA) reaction was studied on magnesium aluminate (MgAl2O4) supported nickel (Ni) and cobalt (Co) catalysts. The catalysts with 8 wt.% of Ni, Co or Ni-Co were prepared by dry impregnation and ...
