Desenvolvimento de procedimentos eletroanalíticos para a determinação de fármacos em formulações farmacêuticas e fluidos biológicos empregando sensores à base de carbon black
(Universidade Federal de São Carlos, 2019-02-28)
In this work, voltammetric methods for determination of losartan potassium and ketoconazole using an electrode modified with carbon black were developed. Originally, a sensor was constructed with carbon black, chitosan and ...
Acilação e alquilação fotoquímica de heteroarenos utilizando diacetil
(Universidade Federal de São Carlos, 2018-11-01)
N-heterocycles are important building blocks in the synthesis of bioactive compounds, besides that many of them are present in natural products. Most of the methodologies for heteroarene functionalization requires several ...

(Universidade Federal de São Carlos, 2019-02-25)
Furans are important heterocyclics with broad application in synthesis as a building block, frequently presented in a wide range of compounds that exhibit biological activity, including natural products. Intramolecular ...
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Spinel of manganese and lithium undoped and doped with aluminum were obtained by an unpublished, energy saving, short time, and low temperature synthesis: microwave-assisted hydrothermal route.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 ...
