Titanatos de alcalinos terrosos : a ordem associada à desordem
(Universidade Federal de São Carlos, 2010-02-26)
The microwave-assisted hydrothermal method was implemented in the synthesis of alkaline earth titanates under ABO3 stoichiometric known as perovskites, being efficient and innovative. For that, OH- groups played an important ...
Estudo das propriedades ópticas e estruturais de nanocristais de ZnS, obtidos pelo método solvotérmico aquecido por microondas
(Universidade Federal de São Carlos, 2013-04-26)
This work deals with the synthesis, characterization and study of nanostructures of zinc sulfide (ZnS) synthesized by microwave heated solvothermal method The synthesis method employed was extremely efficient leading to ...
Estudo teórico das propriedades ópticas dos BaWO4 e PbWO4
(Universidade Federal de São Carlos, 2012-09-21)
Among the scheelites, we highlight the Barium Tungstats (BaWO4) and lead tungstate (PbWO4). These compounds can be synthesized by various synthetic routes. However, we can highlight the hydrothermal synthesis method assisted ...
Fotoluminescência de nanopartículas de Ni(OH)2 e avaliação catalítica de NiO na redução de NO com CO
