Estudo das eletrodeposições de lítio e gálio sobre Au(111) e HOPG utilizando líquido iônico como eletrólito
(Universidade Federal de São Carlos, 2009-03-06)
In the present work, the electrodepositions of lithium and gallium on Au(111) and HOPG (highly oriented phyrolytic graphite) were studied using ionic liquids (ILs) as electrolytes and employing the following techniques: ...
Aplicação de nanopartículas em filmes utilizados em embalagens para alimentos
(Universidade Federal de São Carlos, 2009-04-30)
Dispersions composed of chitosan (CS) were obtained by the template polymerization (CS-PMAA) and ionotropic gelatinization (CS-TPP). The nanoparticles were analyzed by FT-IR analysis, particle size, zeta potential, electron ...
Estudo da Influência do Sm e Er em Cerâmicas de PbTiO3.
(Universidade Federal de São Carlos, 2005-04-29)
In this work, it was obtained powders and thin films of (Pb1-xLnx)TiO3, Ln = Sm and Er, using a chemical method of synthesis, polymeric precursor method (Pechini). In this
way, the synthesis conditions were optimized in ...
Dióxido de estanho nanoestruturado dopado com terras raras como catalisador e sensor de gases.
(Universidade Federal de São Carlos, 2004-02-10)
This work presents and discusses results of the effects of doping on rare earth-doped nanosize SnO2, obtained using the polymeric precursor method and prepared at different annealing temperatures. Only the cassiterite phase ...
Pigmentos cerâmicos nanométricos a base de CeO2 dopado com Pr6O11, NiO e CoO.
(Universidade Federal de São Carlos, 2005-09-30)
In the last few years, the study of ceramic materials has increased very fast, mainly studies related to advanced ceramics. The several applications of these materials as ceramic pigments in nanometric scale justify more ...
Termodinâmica de líquidos iônicos via simulação computacional.
(Universidade Federal de São Carlos, 2006-10-04)
In this work classical molecular dynamics was used to study the
pure ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate,
[BMIM]+[BF4]-, and some solutions based in it. The OPLS-AA force field and
CHelpG derived ...
