(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, ...
