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 ...
Detecção e degradação eletroquímica de dexametasona usando eletrodos de diamante dopado com boro
(Universidade Federal de São Carlos, 2022-12-16)
Dexamethasone is a glucocorticoide, first synthesized in 1957, that is currently part of the World Health Organization's List of Essential Medicines. Thus, as na important drug, its potential for environmental contamination ...
Avaliação da atividade fotoeletrocatalítica dos filmes de CuO/NiOx, CuO/Cu2O/CuS e WO3/MoO3-x frente a fotoeletrólise da água para a produção de H2 verde
(Universidade Federal de São Carlos, 2023-02-24)
The use of solar energy is essential for the future of humanity. In this context, the conversion of this energy into chemical energy, using low-cost technologies, such as photoelectrochemical cells (PECs), has gained ...
Development of Hematite-based photoanodes
(Universidade Federal de São Carlos, 2023-02-17)
Hydrogen production via Water Splitting has been considered one of the best solutions for energy shortages and environmental pollution. The use of hematite (α-Fe2O3) as a photoanode in photoelectrochemical hydrogen production ...
Nanocompósitos na forma de fibras poliméricas à base de policaprolactona com hidrotalcita imobilizada para a adsorção de ácido clorogênico
(Universidade Federal de São Carlos, 2023-08-25)
Water, vital for humanity, is widely used in coffee processing, resulting in effluents with a high organic load, including polyphenols that can be harmful to the environment. Adsorption is a simple and effective strategy ...
