Fotoluminescência do CaMoO4, MgTiO3 e b-ZnMoO4: um estudo teórico
(Universidade Federal de São Carlos, 2015-03-06)
In this work, calcium molybdate (CaMoO4) crystals, MgTiO3 (MTO) thin films and beta zinc molybdate (b-ZnMoO4) microcrystals were
synthesized by the different methods and structurally characterized X-ray diffraction (XRD), ...
Estudo de estruturas, interações e reconhecimento molecular em carboidratos utilizando simulação computacional.
(Universidade Federal de São Carlos, 2004-05-11)
In this work, computer simulation methods were applied to investigate glucose-derived carbohydrates in solution at atomistic resolution. The carbohydrates considered were: trehalose and cyclodextrins. The disaccharide ...
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 ...
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., ...
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 ...

Mecanismos eletroquímicos nos processos de descarga do sistema PbO2/H2SO4
(Universidade Federal de São Carlos, 2017-11-17)
The goal of this work was to seek a mechanistic and morphological understanding of the discharge process of lead-acid batteries’ positive plates, which exhibits a complex porous structure. Due to this fact, nonporous ...
Dinâmica de colisões eletrônicas com moléculas orgânicas voláteis: seções de choque de ionização e diferenciais elásticas
(Universidade Federal de São Carlos, 2016-12-16)
ELECTRONIC COLLISIONS WITH VOLATILE ORGANIC MOLECULES: IONIZATION AND ELASTIC DIFFERENTIAL CROSS SECTIONS. In this work we report an
experimental investigation of the dissociative ionization processes induced by ...
Morfologia e propriedades estruturais de óxidos metálicos complexos: um enfoque teórico e experimental
(Universidade Federal de São Carlos, 2018-07-18)
Design, control and direct characterization of the properties of the surfaces are prerequisites for all practical applications of (nano) materials. Within this context, the present doctoral thesis is an experimental and ...
Estudo mecanístico de reações de estado sólido: o caso do sistema Pb/PbSO4/Na2SO4
(Universidade Federal de São Carlos, 2012-11-21)
In this work, the growth and reduction of PbSO4 in Na2SO4 solution under transient conditions was characterized. A novel methodology for the working-electrode surface preparation before stabilization enhanced the voltametric ...
