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 ...
Análise de metabólitos secundários produzidos por fungos endofíticos associados à Cupressus lusitanica
(Universidade Federal de São Carlos, 2009-02-12)
Some phytopatogenic fungi found in Cupressus species produces phytotoxins very aggressive to the host plant. Surprisingly, these toxins are diterpenoids structures, as well as some endogenus metabolites in Cupressus species. ...
Metabolismo secundário de fungos endofíticos do gênero Penicillium associados às plantas Murraya paniculata (Rutaceae) e Melia azedarech (Meliaceae).
(Universidade Federal de São Carlos, 2005-12-14)
The Penicillium sp. A, Penicillium sp. B (M. paniculata) and P. herquei (M. azedarach) fungus were grown in liquid media (Czapeck s)
and also in solid media (rice). After the inoculation of the fungus, their grownth
were ...
Contribuição ao estudo do metabolismo micromolecular de Xylaria sp., um fungo endofítico isolado de Sapindus saponaria
(Universidade Federal de São Carlos, 2006-12-15)
This work reports the study of a surprising plant microorganism relationship, involving the plant Sapindus saponaria, which is rich in antigungal saponins, and an endophyte fungus isolated from the pericarpe of the fruits ...
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 ...
Adição de Michael de α,α-Diciano-Olefinas a Chalconas via organocatálise assimétrica empregando solvente derivado de biomassa
(Universidade Federal de São Carlos, 2018-05-18)
In recent years, organocatalysed reactions have become an important field in asymmetric synthesis. Particularly, Michael addition reactions using various donors and acceptors have been explored to generate substrates that ...
