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 ...
Propriedades fotoluminescentes do CuMoO4
(Universidade Federal de São Carlos, 2011-12-19)
In this study, CuMoO4 were synthesized, characterized and crystallized into powders in two structures: monoclinic and triclinic. CuMoO4 powder were synthesized by precipitation, and the reaction s pH were controlled due ...
Estudo das propriedades eletroquímicas e magnéticas do polipirrol
(Universidade Federal de São Carlos, 2010-11-22)
In this work the electrochemical degradation of polypyrrole films was studied by means of an applied overpotential and the magnetic properties of polypyrrole pellets, when these were modified by the incorporation of metallic ...
