Síntese eletroquímica e caracterização de filmes finos de Sb2Se3
(Universidade Federal de São Carlos, 2017-12-05)
Due to the environmental appeal, the shortage of raw material and the chemical complexity of some systems employed at photovoltaic devices, interest has been growing for semiconductors composed of abundant, low toxicity ...
Estudo de formação de tris-acetal internoe espiro-carbocíclicos a partir de (R)-(–)-e espiro-carbocíclicos a partir de (R)-(–)
(Universidade Federal de São Carlos, 2016-11-07)
In this work we studied, initially, the formation of the internal tris-ketals derivatives from their respective 2,2-bis-propargyl cyclic ketones from catalysis by gold complexes.
The reaction conditions were studied for ...
Diferenciação e caracterização química de espécies de Phyllanthus utilizando técnicas hifenadas
(Universidade Federal de São Carlos, 2016-01-15)
Several species of Phyllanthus genus are widely used in popular
medicine, even though very few phytochemical reports on species such as: P.
caroliniensis, P. stipulatus and P. tenellus are found in the literature. ...
Estudo do processo de eletrofiação de micro/nanofibras de polímeros biodegradáveis para liberação do antibiótico Cloxacilina
(Universidade Federal de São Carlos, 2018-02-28)
Bovine mastitis disease is caused by some class bacteria and fungus from the environment, which affects the dairy cattle herd. This disease can cause financial damage to farmers by reducing cattle milk production. In this ...
Vidros fosfatos com tungstênio: incorporação de cátions alcalinos e sua influência nas propriedades estruturais e condutoras
(Universidade Federal de São Carlos, 2018-03-23)
Many glasses have been studied as solid
electrolytes in behalf of replacing commercial liquid electrolytes. However, even
for the best glass compositions available in the literature, values of conductivity
similar to ...
Sintese e avaliação de peptidomiméticos contendo heterociclos de três membros como inibidores de catepsina L
(Universidade Federal de São Carlos, 2017-12-01)
Cathepsin L is a lysosomal cysteine protease, that is related to many physiological processes, however overexpression and up- or downregulation may cause several pathologies. Therefore, cathepsin L became an interesting ...
Caracterização funcional de uma Cisteíno Catepsina recombinante da formiga cortadeira Atta Sexdens
(Universidade Federal de São Carlos, 2018-04-27)
Cutting ants depend on plant leaves to survive, presenting high damage power in agricultural productions, natural and planted forest. The control of these insects through the use of commercial insecticides besides being ...
Síntese e estudo das propriedades fotoluminescentes e fotocatalíticas dos cristais de Ag2-2xMxWO4, (M = Mg e Zn)
(Universidade Federal de São Carlos, 2014-06-03)
This study aimed to investigate the photoluminescence and photocatalytic properties of the alpha phase of silver tungstate ( α-Ag2WO4 ) doped with Mg and Zn (where M = Mg or Zn and x = 0; 0,01; 0,02; 0,04 ou 0,08). The ...
Desenvolvimento de uma nova rota de síntese hidrotermal assistida por micro-ondas para a obtenção de nanopartículas de espinélios de manganês e lítio dopados com alumínio para aplicação em baterias de íons lítio
(Universidade Federal de São Carlos, 2018-03-01)
Spinel of manganese and lithium undoped and doped with aluminum were obtained by an unpublished, energy saving, short time, and low temperature synthesis: microwave-assisted hydrothermal route. Undoped spinel was synthesized ...
Estudos metabolômicos e biossintéticos visando contribuições para a química e taxonomia de microorganismos da família Xylariaceae
(Universidade Federal de São Carlos, 2014-11-11)
The PhD work aimed the exploration of fungal metabolism of NICL3 and NICL5, both initially identified as Xylaria sp., isolated as endophytic fungi from Cupressus lusitanica. The investigation of the NICL3 metabolism allowed ...
