Eletrodeposição de filmes do tipo Ni-X (X=P, Cu ou Cu-P) a partir de banhos contendo aspartato
(Universidade Federal de São Carlos, 2022-11-25)
In the present work, aspects related to the electrodeposition of Ni-based metal films - either pure metal or Ni-P, Ni-Cu, and Ni-Cu-P alloys - from baths containing aspartate complexes as electroactive species and hypophosphite ...
Desenvolvimento de membranas poliméricas enantiosseletivas utilizando partículas tipo-Pirkle para resolução de compostos quirais
(Universidade Federal de São Carlos, 2023-02-15)
The formation of chiral compounds during the synthesis of new drugs and other substances, which are administered clinically in the form of racemic mixture, is amply described in the literature. The therapeutic activity of ...
Gels and sponges nanocomposites based in chitosan, poly (n-vinyl caprolactam) and sio2 applied as drug delivery system
(Universidade Federal de São Carlos, 2023-06-14)
Chitosan (Ch) is a suitable biomaterial for biological applications like drug delivery systems (DDS) due to biocompatibility, cationic responsiveness, and adjustable morphology forming nanoparticles, films, sponges, etc. ...
Desenvolvimento de eletrocatalisadores de sulfeto de molibdênio para produção de hidrogênio via eletrólise da água
(Universidade Federal de São Carlos, 2023-03-31)
The amorphous molybdenum sulfide, MoSx, has shown to be an excellent electrocatalyst for the hydrogen evolution reaction (HER) and can be synthesized by electrodeposition. In this study, the electrodeposition of MoSx on ...
Espectroscopia eletrônica de moléculas halogenadas
(Universidade Federal de São Carlos, 2022-09-29)
We present a theoretical-experimental investigation of the valence state excitation of dichloromethane (CH2Cl2) and trichloromethane (CHCl3) molecules in the gas phase. The CH2Cl2 molecule was investigated using electron ...
Correlação estrutura x propriedades de transporte de CO2 em membranas de poli(éterimida)/líquido iônico
(Universidade Federal de São Carlos, 2017-09-28)
The increase in the emission of carbon dioxide (CO2) from the burning of fossil fuels contributes directly to changes in the environment. For post-combustion CO2 capture, the use of polymer membranes has gained prominence ...
