Seção de choque total para interação de elétrons com moléculas poliatômicas.
(Universidade Federal de São Carlos, 2005-08-30)
Total Cross Sections (TCS) for various
processes resulting from the interaction of electrons with poliatomic molecules
are clearly needed due to their relevance in many applications. The present study
is part of a complete ...
Transporte e morfologia de esquemas de tintas epóxi poliamina equivalentes à base de solvente e água.
(Universidade Federal de São Carlos, 2003-07-21)
In the present work, anticorrosive properties of solvent borne and water based epoxy polyamine coatings were studied comparatively. First these studies were performed for the individual layers of these coatings, i.e., ...

(Universidade Federal de São Carlos, 2010-09-27)
The current market demands make with what Brazilian agribusiness search improvements in processes and new materials to reduce waste, pollution and biological contamination. Mainly materials that more are easily degraded ...
Avaliação da atividade catalítica de óxidos cerâmicos na conversão de óleos vegetais
(Universidade Federal de São Carlos, 2011-02-04)
Organic pollutants are one of the major problems related to water and environmental pollution. Nowadays, vegetable oils represent a considerable source for water contamination. The search for new strategies to provide an ...
Filmes finos de LaNiO3 depositados sobre substratos monocristalinos pelo método dos precursores poliméricos.
(Universidade Federal de São Carlos, 2004-08-06)
This work reports a systematic study on the deposition and characterization of LaNiO3 thin
films. This material is a ceramic conductor and presents a near metallic behavior, and is interesting for capacitor electrodes ...
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 ...
Estudo de pós cerâmicos de PbTiO3 utilizando-se o método dos precursores poliméricos.
(Universidade Federal de São Carlos, 2000-11-30)
THE STUDY OF PbTiO3 (PT) CERAMIC POWDERS USING THE POLYMERIC PRECURSOR METHOD was started by the preparation of a precursor solution of metallic cations. Citric acid was used as quelation agent and ethylene glycol as ...
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 ...
