Desenvolvimento e modificação a plasma de materiais a base de poli(ácido lático)/α-Ag2WO4 com potencial ação antimicrobiana
(Universidade Federal de São Carlos, 2022-01-28)
Recently, the world has been facing several microbial infections that have caused great losses and fatalities. In this scenario, the development of new materials that can be used to fight these potentially pathogenic ...
Complexos fosfínicos de Ru(II)/mercaptos contendo ligantes N,N-heterocíclicos: atividade citotóxica e mecanismo de ação
(Universidade Federal de São Carlos, 2022-12-16)
The main objectives of this study were the synthesis, characterization and biological studies of two series of ruthenium phosphine compounds containing different mercapto ligands, and contrasting in N,N-heterocyclic ligands ...
Metabolismo de daidzeína e genisteína por Spodoptera frugiperda
(Universidade Federal de São Carlos, 2021-09-20)
DAIDZEIN AND GENISTEIN METABOLISM BY Spodoptera frugiperda. As
sessile organisms, plants cannot escape the many herbivore attacks that occur
throughout their development, and rely on alternative strategies to reduce ...
Polipropileno reciclado para contato com alimento: etching e deposição de filmes de carbono amorfo hidrogenado por plasma
(Universidade Federal de São Carlos, 2020-09-30)
The increasing applications of polymers make this material one of the most consumed in the world market. Accompanying this scenario is the generation of waste, and although plastic has gradually conquered its space as a ...
Reações de fotooxigenação de pinenos em pinocarvonas, trans-pinocarveóis e mirtenal: uma abordagem em regime de fluxo contínuo
(Universidade Federal de São Carlos, 2022-04-18)
In this work, a continuous flow protocol to prepare (-)-pinocarvone, (-)-trans-
pinocarveol and (+)-myrtenal from (+)--pinene, (-)--pinene and -pinene through
photooxygenation reactions was described. Furthermore, ...
Estudo empírico-teórico de compósitos baseados em polímeros condutores para conversão e armazenamento de energia
(Universidade Federal de São Carlos, 2018-10-26)
The fast obsolescence of still functional devices causes an extensive e-waste generation and an exacerbated natural resources consumption for the manufacture of new products. In this sense, the development of abundant ...
Investigação da corrosão do aço carbono AISI 1020 em soluções de NaCl utilizando microscopia óptica in situ
(Universidade Federal de São Carlos, 2016-09-23)
According to recent information from the World Corrosion Organization, annually, approximately 2.2 trillion of global GDP is spent on corrosion-related damage. These expenses are almost the GDP of the seventh world economy ...
Síntese e caracterização de nanotubos de TiO2 preparados eletroquimicamente
(Universidade Federal de São Carlos, 2016-04-20)
In the field of nanotechnology, the titanium dioxide (TiO2) has been widely studied for its optical and electrical properties. This oxide is an n-Type semiconductor and is found naturally in
different crystalline phases. ...
Utilização do sinal de fundo e calibração multivariada como um procedimento para acessar a concentração total de concomitantes em espectrometria de absorção atômica com forno tubular na chama e aerossol térmico (TS-FF-AAS)
(Universidade Federal de São Carlos, 2009-02-19)
TS-FF-AAS employs a metal tube atomizer above an air/acetylene flame and in this case, the atoms residence time is longer than that observed in FAAS (Flame AAS). As a result, elevated background signals are obtained. For ...
Desenvolvimento de catalisadores bifuncionais a base de fosfato e suas aplicações catalíticas
(Universidade Federal de São Carlos, 2022-02-17)
The development of bifunctional acid catalysts is an area of heterogeneous catalysis in intense growth, mainly due to the possibility of performing consecutive reactions using a single catalyst and a single reactor. In ...
