Complexo luminescente de Ru(II)-Perileno: avaliação da citotoxicidade e da fotocitotoxicidade em células de melanoma murino B16F10 in vitro e in vivo
(Universidade Federal de São Carlos, 2017-08-17)
Cutaneous melanoma is one of the most feared cancers worldwide due to resistance to treatments and the high capacity to develop metastases. Photodynamic therapy (PDT), a minimally invasive therapeutic modality, is a promising ...
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 ...
Instabilidades em eletrocatálise: cinética complexa catalisada por superfícies modelo
(Universidade Federal de São Carlos, 2018-02-28)
The electro-oxidation of small molecules is an area of great interest due to its application in energy converting systems, such as fuel cells. The reactions present in these systems involve several reaction pathways - which ...
Estudo de nanocompósitos de pectina com nanopartículas de quitosana e carvacrol para aplicação em embalagens
(Universidade Federal de São Carlos, 2017-10-27)
Brazilian researchers have performed out several works and developed several products from nanostructured materials, which has resulted in an expansion in its research. One of these research fields is focused on minimizing ...
Investigação das propriedades ópticas e fotocatalíticas de materiais a base de fosfato de prata
(Universidade Federal de São Carlos, 2019-08-05)
The semiconductor-based photocatalytic degradation of synthetic dyes has been considered a promising approach in wastewater treatment. The main objective in this doctoral thesis was the investigation on structural, ...
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, ...
Estratégias espectroanalíticas para análise química inorgânica de plantas medicinais
(Universidade Federal de São Carlos, 2014-12-01)
This thesis describes the development of analytical procedures based on direct solid analysis by high-resolution continuum source atomic absorption spectrometry in graphite furnace (SS-HR-CS GF AAS) and aqueous solutions ...
Estudo de alterações metabólicas nos fungos endofíticos Penicillium brasilianum e Penicillium griseoroseum
(Universidade Federal de São Carlos, 2011-08-26)
Microorganisms, known as being relatively simple, have shown a great adaptation power to different nutritional situations by changing their metabolism with lack or supply of nutrients in the culture medium. This feature ...
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 ...
