Estudo do crescimento e automontagem de nanocristais coloidais
(Universidade Federal de São Carlos, 2012-12-07)
In the last two decades a remarkable progress in nanomaterials knowledge has been done, mainly in the chemical synthesis of inorganic nanocrystals via colloidal processes. Several of these advances addressed the growth ...
Fotoluminescência de nanopartículas de Ni(OH)2 e avaliação catalítica de NiO na redução de NO com CO
(Universidade Federal de São Carlos, 2010-08-10)
In recent years, nanostructured oxides have attracted great interest from different areas of technology due to the possibility of developing new devices or electro-optical equipment. In principle, the physical and chemical ...
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 ...
Avaliação e caracterização da borracha natural de diferentes clones de seringueira cultivados nos estados de Mato Grosso e Bahia
(Universidade Federal de São Carlos, 2010-03-02)
Natural rubber (NR) is a basic raw material used in the manufacture of a wide range of rubber goods. Usually both quality and productivity levels of Brazilian NR are lower than the imported NR. This is due to a lack of ...
