Indicadores de patentes para o monitoramento tecnológico em aços para dutos utilizados em transporte de hidrocarbonetos
(Universidade Federal de São Carlos, 2016-08-05)
Most part of the hydrocarbons reserves used in the global energy matrix are far
from their main consumer markets. One of the most technically and
economically viable means for such transport is carrying it out ...
Estudo do processo de soldagem a ponto por fricção de juntas dissimilares entre ligas de alumínio e titânio
(Universidade Federal de São Carlos, 2016-12-09)
Multimaterial structures between aluminum and titanium alloys are a
technologically attractive field of research and their increasing use in the
transportation sector for weight and emission reduction is part of the ...
Desenvolvimento de nanocompósitos híbridos de epóxi/NTCPM/cargas minerais e avaliação das propriedades mecânicas, elétricas e térmicas
(Universidade Federal de São Carlos, 2016-07-11)
In the present work epoxy/ MWCNT/ mineral fillers nanocomposites were
obtained using ultrasonication and calendering. The effect of addition of mineral
filler (calcium carbonate, montmorillonite and sepiolite) in electrical, ...
Avaliação da ação de estabilizantes anti-UV no desempenho de compósitos de polipropileno, reforçados com fibras de coco, submetidos a diferentes técnicas de envelhecimento artificial
(Universidade Federal de São Carlos, 2016-06-30)
Currently, there has been a search for economically viable and sustainable
products in various market segments. Lighter materials that can be recycled
have become a strategic issue for many industries. In this sense, the ...
Identificação das variáveis que ocasionam a variação de tonalidade utilizando a técnica de decoração por cilindros de silicone gravados a laser
(Universidade Federal de São Carlos, 2015-11-30)
A major problem in the production of ceramic tiles for coating is the variation of
tonality. The determination of their origin within the entire production process and to
minimize its occurrence by the manufacturer is ...
Zircônia CO-dopada por compensação de cargas nos sistemas (ZrO2)1-(x+y)(InO1,5)x(MOz)y com MOz = TaO2,5, NbO2,5, MoO3 ou WO3, como revestimento para barreira térmica
(Universidade Federal de São Carlos, 2016-09-30)
InO1.5-stabilized zirconia (InSZ) is a potential hot corrosion resistant thermal
barrier coating (TBC). However, the thermal instability prevents real applications
of InSZ-based TBC. This thesis investigates the hypothesis ...

The objective of this work was the development of polymer
nanocomposites with montmorillonite organoclays (OMMT) using EVA-OMMT
concentrated obtained by spray drying, Drais and extrusion, making the
characterization and ...
Atomização e consolidação por fusão seletiva a laser da liga Cu-11,3Al-3,2Ni-3,0Mn-0,5Zr com efeito de memória de forma
(Universidade Federal de São Carlos, 2015-12-16)
The aim of the present work was the study of the viability of a manufacturing route of parts with the Cu-based Shape Memory Alloy (SMA) Cu- 11,3Al-3,2Ni-3Mn-0,5Zr through gas atomization followed by Selective Laser Melting ...
Investigação do desenvolvimento microestrutural de eletrólito sólido β/β’’-alumina visando sua utilização em bateria ZEBRA
(Universidade Federal de São Carlos, 2014-10-09)
The ZEBRA battery (Zero Emission Battery Research Activity) is an efficient electrochemical energy storage device with high energy density and high power. This has been considered one of the key technologies for insertion ...
Preparação de nanocompósitos baseados na intercalação de argilominerais em matrizes ureia-formaldeído para aplicação como fertilizantes de liberação controlada
(Universidade Federal de São Carlos, 2014-02-27)
The increase on the price of fertilizers, and the high Brazilian importing
dependency of this material, raise the cost of cultures. Such cost may be
reduced by more efficient and efficiently used fertilizers. From an ...
