Síntese de nanopartículas semicondutoras de seleneto de zinco (ZnSe) aquoso e análise dos subprodutos decorrentes dessa síntese
(Universidade Federal de São Carlos, 2012-07-20)
Zinc selenide (ZnSe) is a semiconductor material, which band gap is about 2.7 eV. It has many applications as blue light emission diode, data storage devices, laser diodes and waveguides optical fibers. Despite these several ...
Estudo do efeito isotópico sobre a solubilidade da 3- metilpiridina em H2O e D2O
(Universidade Federal de São Carlos, 2012-12-07)
Experimental studies of 3-methylpiridyne/water and 3- methylpiridyne/heavy water binary mixtures show solubility differences. In this work Molecular Dynamics method was used to simulate 54 model systems. Each system ...
Confinamento de líquidos em nanoescala
(Universidade Federal de São Carlos, 2012-02-27)
The effects on the reduction of space on the structural properties of two liquids and a mixture thereof were analyzed with a definition of nanoscale confinement, based on carbon nanotubes. The methodology involves the use ...
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 ...
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 ...
