Efeito de diferentes solventes nas propriedades fotoluminescentes do CaMoO4
(Universidade Federal de São Carlos, 2013-08-02)
The CaMoO4 has been extensively studied due to its luminescent emissions in the visible region of the electromagnetic spectrum at room temperature, presenting potential for technological applications including lasers, light ...
Desenvolvimento e estudo da estabilidade de nanoemulsões do tipo óleo em água com óleos vegetais
(Universidade Federal de São Carlos, 2011-10-11)
A low energy emulsification method was used to prepare o/w emulsions of sweet almond or Brazil nut oils stabilized by Tween 80 and Span 80. Stable nano emulsions with droplet size of 160 nm and 270 nm were obtained for ...
Estudo da estrutura de complexos de polieletrólitos sobre as propriedades de transporte de água e sais
(Universidade Federal de São Carlos, 2015-03-25)
Polyelectrolytes complexes (PECs) are defined as materials formed by combining oppositely charged polyelectrolytes together via ionic interaction. PECs have some unique physical properties such as non-solubility in common ...
Crescimento anódico e caracterização de óxidos coloridos de titânio em eletrólitos alternativos
(Universidade Federal de São Carlos, 2015-01-23)
A Studies on the anodic growth of oxides that passivate the biomaterial titanium, and their electrochemical, morphological and structural parameters were carried out in this work. The oxides were obtained galvanostatically ...
Uso de biotemplates na obtenção de microtubos com nanopartículas de ouro
(Universidade Federal de São Carlos, 2014-02-14)
Recently, the studies in the area of hybrid materials composed by biological structures have been of great interest, since they are considered versatile biotemplates in wich referred to the organization of nanostructured ...
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 ...
Simulação do crescimento de filmes sobre metais. O caso voltamétrico
(Universidade Federal de São Carlos, 2008-07-02)
In this work the anodic film growth on metals has been studied, under voltammetric conditions by simulation. It was supposed that: a) the films are ultrathin, i.e., the concentration gradient contributions for the ionic ...
Termodinâmica de líquidos iônicos via simulação computacional.
(Universidade Federal de São Carlos, 2006-10-04)
In this work classical molecular dynamics was used to study the
pure ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate,
[BMIM]+[BF4]-, and some solutions based in it. The OPLS-AA force field and
CHelpG derived ...
