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 ...
Sensores nanoestruturados compostos por nanofibras de dióxido de titânio modificadas com polímeros condutores visando monitoramento de compostos orgânicos voláteis
(Universidade Federal de São Carlos, 2020-03-18)
The growth of urbanization and anthropogenic activities have been increasing the emission of polluting gases in the atmosphere. Considering the high toxicity of some of these gases, it becomes necessary to develop new ...

This work reports the synthesis, characterization and investigation of the electronic properties of heterocomplexes formed by cobalt(II) tetrakis(N-methyl-4- pyridyl)porphyrin (CoTMPyP) and cobalt(II) 4, 4 , 4 , 4 , ...
Efeitos térmicos durante a foto-eletro-oxidação de glicerol catalisada por CdS
(Universidade Federal de São Carlos, 2019-10-25)
Cadmium sulfide (CdS) is one of the most important chalcogenides applied to water splitting, which has a band gap of 2.4 eV that suits very well with the solar spectrum. Moreover, CdS possesses a strong reduction activity ...
Síntese de acil fosfodiésteres por mecanoquímica: uma metodologia de química verde
(Universidade Federal de São Carlos, 2019-08-22)
Green chemistry is very concerned with the sustainability of chemical reactions, where one of the objectives, which in the formulation/remodeling of synthetic routes can replace toxic solvents with solvents of lower toxicity, ...
Estudo microestrutural dos contornos de grão em estágio inicial de formação no sistema cerâmico ZnO-Bi2O3
(Universidade Federal de São Carlos, 2019-08-28)
Polycrystalline materials have solid-solid interfaces known as grain boundary. These interfaces have long been treated as just a region of defects between the crystals (grains), but recent studies have shown that such ...
