Nanocristais de TiO2 : relação entre parâmetros morfológicos, estruturais e fotocatálise
(Universidade Federal de São Carlos, 2010-02-26)
In this work, morphologically different TiO2 nanocrystals were synthesized through the OPM method with the objective of performing a comparative study related to photoactivity. Morphological characterization was performed ...
Desenvolvimento de nanocompósitos baseados em hidrogéis aplicados à liberação de nutrientes agrícolas
(Universidade Federal de São Carlos, 2014-03-21)
Nanocomposites were developed based on polyacrylamide hydrogels (PAAm) and methylcellulose (MC) reinforced with montmorillonite (MMT), undergoing the materials to subsequent hydrolysis process and evaluating their loading ...
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 ...
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 ...
Método solvotérmico assistido por micro-ondas aplicado à obtenção de nanocristais de ITO : deposição e caracterização de filmes de ITO
(Universidade Federal de São Carlos, 2012-02-17)
The formation of In1-xSnxO2 (ITO) nanocrystals through the conversion of radiant energy into heat has been studied by using an adapted domestic microwave oven. The formation of powder was obtained by heating the oven to ...
