Estudo dos processos de eletrodeposição de filmes finos de Se, ZnSe e PbS
(Universidade Federal de São Carlos, 2008-03-13)
This work describes studies on the underpotential deposition (UPD) of selenium, zinc, as well for Zn/Se systems deposited on polycrystalline Pt electrodes in acid solutions. The effects of Zn presence in the Se dissolution ...
Avalição química e da capacidade de biossorção da grama batatais (Paspalum notatum) visando aplicações analíticas.
(Universidade Federal de São Carlos, 2004-09-03)
This work suggests the chemical characterization of the genus Paspalum and was divided in 3 steps: 1) sample preparation of plants with diluted acids; 2) biosorption studies employing
Paspalum notatum root material, and ...
Estrutura e propriedade fotoluminescente do titanato de bário e cálcio obtido pelo método de polimerização de complexos (MPC)
(Universidade Federal de São Carlos, 2008-06-16)
The synthesis and characterization of Ba1-xCaxTiO3 (BCT) for x = 5; 10; 15; 20; 40 e 80 % mol that crystallizes in a perovisquita structure were studied in this work. The BCT material was synthesized by CPM which allows ...
Estudo do mecanismo de oxidação do herbicida atrazina na presença de minerais e sustâncias húmicas em ambiente anaeróbio.
(Universidade Federal de São Carlos, 2005-12-14)
The oxidative decomposition of atrazine was induced by hydroxyl radicals generated from the interaction between hydrogen peroxide, H2O2, and iron oxides, yielding the
Fenton reaction. The reaction rate of atrazine oxidation ...
Ligação covalente coordenada boro-nitrogênio : um estudo comparativo entre moléculas derivadas do etano, eteno e etino orgânicos e inorgânicos
(Universidade Federal de São Carlos, 2016-12-06)
This work consists in the theoretical analysis and comparison of some
organic compounds and its similar inorganics, through the change of the BN pair,
and, in some cases, the BP pair, in the place of CC pair. First, ...
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 ...
Alguns aspectos químicos envolvidos na interação Hypsipyla grandella (broca-do-mogno e Swietenia macrophylla (Mogno)
(Universidade Federal de São Carlos, 2002-11-08)
The interaction between Hypsipyla grandella (Mahogany bore) and Swietenia macrophylla was studied in order to understand the chemical and ecological aspects involved on this process. H. grandella is a shoot borer lepdoptera ...
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 ...
