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 ...
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 ...
Fotocatálise e suas aplicações em reações de ciclização oxidativa e terapia fotônicas
(Universidade Federal de São Carlos, 2019-05-06)
In the chapter 1, studies on photocatalysed reactions were carried out by porphyrins and other photocatalysts aiming at the formation of radicals in amino aromatic systems for subsequent addition reaction. More specifically, ...
Otimização do processo de mineralização de compostos orgânicos utilizando sistemas eletro-Fenton e fotoeletro Fenton por irradiação UV artificial e solar
(Universidade Federal de São Carlos, 2011-09-30)
Electrochemical advanced oxidation processes based on the Fenton s reaction, such as electro-Fenton (EF) and photoelectro-Fenton (PEF) using artificial and solar UV irradiation were employed in the treatment of effluents ...
Heterostructure formation of BiVO4 with different Bi compounds : role of the heterojunction on photocatalytic properties
(Universidade Federal de São Carlos, 2016-08-29)
Semiconductors employed as photocatalysts that can be activated by
visible irradiation have attracted intense scientific interest due to their applications in
heterogeneous photocatalysis. BiVO4 is a semiconductor with ...
Hidrogéis magneto-reponsivos para liberação estimulada de fármacos
(Universidade Federal de São Carlos, 2018-05-08)
Nanocomposite hydrogels modified with polysaccharides, minerals clay and magnetic nanoparticles of iron oxide functionalized with polymeric material were developed, allowing higher interaction between the nanoparticles and ...
Estudo In vitro de nanocompósitos para a liberação lenta de nitrogênio sobre a alimentação animal
(Universidade Federal de São Carlos, 2016-03-29)
Supplementation with nonprotein
nitrogen (NPN) has been widely used in ruminant feeding in diets of low
quality forages. This is because these animals have a number of microorganisms
in the rumen able to use ammonia for ...
