Nanopartículas de Fe3O4 funcionalizadas e nanocompósitos de base epóxi
(Universidade Federal de São Carlos, 2015-12-17)
The use of metal oxide nanoparticles in nanocomposite has provided new
and interesting properties and is one of the most promising areas in composites.
Compatibility between these nanoparticles and polymer matrix is the ...
Caracterização estrutural e monitoramento ótico da cristalização de nanocompósitos de polietileno de alta densidade com partículas de diferentes geometrias durante a moldagem por injeção
(Universidade Federal de São Carlos, 2014-03-06)
The main objectives of this project were to study the morphology, the crystallization
kinetics and to monitor on-line the crystallization during the injection
molding process using an optical system of nanocomposites of ...
Estudo da dispersão, localização seletiva e efeito compatibilizante de argila montmorilonita em blendas poliméricas de policarbonato/SAN
(Universidade Federal de São Carlos, 2015-03-30)
The present study investigated the compatibilization effect and stabilization on the morphology of polycarbonate/styrene-acrylonitrile blends (PC / SAN) by incorporating montmorillonite clay. A systematic study was realized ...
Influência das condições de eletrodeposição sobre a resistência a corrosão, susceptibilidade à fragilização por hidrogênio e à corrosão sob tensão do aço ABNT – 4340 revestido com liga Zn/Ni
(Universidade Federal de São Carlos, 2011-01-28)
Zinc-nickel alloys were electrodeposited on ABNT 4340 high strength steel in chloride acid media. The effect of the electrolyte composition and electroplating conditions on cathodic efficiency, chemical composition, ...
Spray forming of wear and corrosion resistant bimetallic pipes : from the alloy design to the semi- industrial process
(Universidade Federal de São Carlos, 2016-02-29)
The oil exploitation and production at the pre-salt fields in a safety and efficient
way depends on the development of materials that withstand the severe work
conditions found in these fields. For instance, pipes, such ...
Influência de aditivos pró-degradantes nas degradações abiótica e biótica do polietileno de alta densidade
(Universidade Federal de São Carlos, 2015-03-06)
High density polyethylene (HDPE) is widely used in the manufacture of
packaging disposables and in order to minimize the environmental impact
caused by disposal, have been incorporated, into the HDPE, additives that
promises ...
Desenvolvimento e caracterização de tecidos vítreos flexíveis altamente bioativos
(Universidade Federal de São Carlos, 2015-10-26)
Bioactive glasses were developed by Hench in 1969, and are widely known to have the ability to rapidly form a chemical bond with hard and soft living tissues. Currently, these glasses have been used clinically as biomaterials ...
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 ...
