Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
Estudo das propriedades fotoluminescentes do ZnS e ZnS:Eu obtidos pelo método solvotérmico assistido por microondas
(Universidade Federal de São Carlos, 2012-07-20)
This paper is about the synthesis, characterization and studies of nanostructures of ZnS and ZnS:Eu3+ prepared by microwave-assisted solvothermal method. The influence of the synthesis time in the microwave on the samples ...
Desenvolvimento de compósitos poliméricos baseados em matriz biodegradável e nanozeólitas
(Universidade Federal de São Carlos, 2010-09-27)
The current market demands make with what Brazilian agribusiness search improvements in processes and new materials to reduce waste, pollution and biological contamination. Mainly materials that more are easily degraded ...
Método solvotérmico assistido por micro-ondas aplicado à obtenção de nanocristais de ITO : deposição e caracterização de filmes de ITO
(Universidade Federal de São Carlos, 2012-02-17)
The formation of In1-xSnxO2 (ITO) nanocrystals through the conversion of radiant energy into heat has been studied by using an adapted domestic microwave oven. The formation of powder was obtained by heating the oven to ...
Avaliação da atividade catalítica de óxidos cerâmicos na conversão de óleos vegetais
(Universidade Federal de São Carlos, 2011-02-04)
Organic pollutants are one of the major problems related to water and environmental pollution. Nowadays, vegetable oils represent a considerable source for water contamination. The search for new strategies to provide an ...
Síntese, caracterização e testes eletroquímicos de dióxido de manganês nanométrico como material de eletrodo de supercapacitores
(Universidade Federal de São Carlos, 2018-08-01)
Manganese dioxide was synthesized by a microwave-hydrothermal method using alternative, unprecedented and completely soluble reagents. For such, potassium permanganate and acetone were dissolved in different proportions ...
Determinação simultânea de íons metálicos por meio de técnicas eletroanalíticas e quimiométricas
(Universidade Federal de São Carlos, 2011-05-19)
In this work, the determination of three metallic ions was performed, namely Zn2+, Cd2+ and Pb2+, in very different concentration range, from _g/L until mg/L, using differential pulse anodic stripping voltammetry over ...
