Ternary nanocomposites based on cellulose nanocrystals, conductive materials and electrospun fibers applied in sensors for detection of heavy metals in water
(Universidade Federal de São Carlos, 2019-03-28)
The monitoring of water resources destined for consumption is a subject of outmost importance for population and ecosystems life quality maintenance. The degradation of these resources with heavy metals, usually associated ...
Estudo do potencial eletrostático e da termodinâmica de agregação de surfactantes por simulações de dinâmica molecular
(Universidade Federal de São Carlos, 2018-03-13)
Due to the amphiphilic character, the surfactants tend to be adsorbed at the water surface and, in concentrations larger than the critical micellar concentration, they self-assembling in solution with the purpose to reduce ...
Efeito da promoção de turbulência na hidrodinâmica de um reator tipo filtro-prensa e na degradação eletroquímica do bisfenol S
(Universidade Federal de São Carlos, 2019-06-28)
The kinetics of many electrochemical processes is limited by mass transport, especially at low concentrations of the reactant. The use of turbulence promoters in parallel-plate reactors increases the hydrodynamic turbulence ...
Melquiades: um programa de Monte Carlo para a simulação de sistemas multicomponentes utilizando modelos de potenciais arbitrários
(Universidade Federal de São Carlos, 2017-02-23)
It was developed a general purpose Metropolis Monte Carlo program, which allows to use arbitrary mathematical functions as potential functions for interaction energy calculation, in order to simulate multicomponent system, ...
Investigação do mecanismo de formação de filmes porosos de TiO2 obtidos por anodização galvanostática
(Universidade Federal de São Carlos, 2011-10-20)
In this work the experimental and theoretical aspects of the growth of titanium dioxide obtained by galvanostatic anodization were studied. The _lms were prepared by galvanostatic anodization of titanium, where the curve ...
Estudo da corrosão de aço AISI 1020 em meio de petróleo
(Universidade Federal de São Carlos, 2011-08-11)
The chemical attack on crude oil, which contains corrosive compounds such as H2S, CO2, naphthenic acids and salts dissolved in the aqueous phase, combined with effects of varying pH, temperature, flow and pressure, has ...
Novas rotas para a síntese hidrotérmica de nanoestruturas de óxidos de titânio
(Universidade Federal de São Carlos, 2012-02-28)
The development of new materials has been a major focus of modern science. In order to obtain materials with desired features, studies about synthesis are necessary for a better understanding of their synthetic processes. ...
Desenvolvimento de plataformas nanométricas híbridas baseadas em polímero/enzima visando aplicações em biossensores
(Universidade Federal de São Carlos, 2016-10-27)
Foodborne illness cases are common in Brazil and in the world. However, in many cases the microorganism causing the illness cannot properly identified. In addition, traditional analyses usually employed for identifying ...
Fotoluminescência do CaMoO4, MgTiO3 e b-ZnMoO4: um estudo teórico
(Universidade Federal de São Carlos, 2015-03-06)
