Transporte eletrônico em filmes ultrafinos nanoestruturados : o sistema SNO2:SB
(Universidade Federal de São Carlos, 2015-12-14)
This thesis describes a study of the electronic charge transport properties in antimony-doped tin oxide (ATO) ultrathin films, prepared by two different methods: by colloidal deposition process (CDP) and by pulsed electron ...
Processos difusionais, cristalização e escoamento viscoso em dissilicato de bário vítreo
(Universidade Federal de São Carlos, 2014-04-24)
In this work, we analysed if the viscous flow successfully describes the transport of crystal nucleation and crystal growth structural units that occur at the liquid/crystal interface. In order to do this, we calculated ...
Análise de critérios de seleção de materiais e processos para interiores de aeronaves executivas incorporando aspectos de sustentabilidade
(Universidade Federal de São Carlos, 2015-12-02)
Materials and processes used to manufacture executive aircraft interiors play an important role in aesthetic and competitive product differentiation, in a scenario where there is growing competition and pressures for more ...

Desenvolvimento de compósito de poliuretano reforçado com nanofibrilas de celulose isoladas de candeia (Eremanthus erythropappus)
(Universidade Federal de São Carlos, 2016-02-26)
Candeia (Eremanthus erythropappus) is an important raw material due to the essential oil that can be extracted from the whole tree. The essential oil contains (-)--bisabolol that has an active principle with pharmacological ...
Transformações de fase termoelásticas em ligas com memória de forma a base de Cu-Al-Ni
(Universidade Federal de São Carlos, 2016-02-26)
Shape memory alloys (SMA) have some exceptional properties such as the
shape memory effect and the superelasticity. Both are associated with a
martensitic/austenitic phase transformation. Alloys of the system Cu-Al-Ni, ...
