Catalisadores baseados em nitretos de carbono grafíticos e metais de transição: síntese e aplicações
(Universidade Federal de São Carlos, 2022-03-24)
Carbon nitrides are polymeric compounds with a C3N4 stoichiometric ratio and formed by sp2 nitrogen bonds. Most of the works in the literature uses polymeric carbon nitride as a catalyst for application in organic reactions, ...
Formulação e estudo da citocompatibilidade de hidrogéis termossensíveis contendo partículas bioativas para aplicação em regeneração óssea
(Universidade Federal de São Carlos, 2022-07-29)
Although the osteogenic properties, there are still some limitations to employing bioactive glasses (BG) in the human body, such as potential cytotoxicity and a lack of controlling the morphology of BG particles.
Furthermore, ...
Obtenção e aplicação de fotoanodos baseados em TiO2 com adição de nitretos de carbono polimérico do tipo poli(heptazina imida)
(Universidade Federal de São Carlos, 2022-07-01)
In this work, poly(heptazine imide) carbon nitrides containing metals single atom in the ionic form were evaluated alone and in the combination with TiO2. Initially, a percentage of 2.5% of the nickel-containing material ...
