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 ...
Obtenção e funcionalização da superfície da zeólita FAU particulada e imobilizada em fibras de PLA para a adsorção de corantes
(Universidade Federal de São Carlos, 2017-02-23)
The importance given to the environmental issue leads us to promote the search for resources that minimize the degradation of the environment, especially with respect to water resources area. In this context, there is a ...
