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, ...
Síntese e caracterização de nanopartículas semicondutoras de ZnO@Carbono com estrutura tipo núcleo-casca
(Universidade Federal de São Carlos, 2021-08-05)
In these study, nanoparticles with a core-shell structure of oxide zinc-carbon (ZnO@Carbon) were synthesized using the simple thermal decomposition method of Zn(CH3CO2)2•2H2O in a conventional electric furnace and a hybrid ...
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, ...
Especiação de arsênio em água e tecido de peixe empregando extração em fase sólida (SPE) e espectrometria de emissão óptica com plasma acoplado indutivamente (ICP OES)
(Universidade Federal de São Carlos, 2023-02-28)
The adverse effects caused by potentially toxic elements on the environment and human health vary according to the elements’ species, which differ in terms of toxicity. Arsenic (As) exposure is a global public health ...
