BaCeO3 dopado com 5%Mol Y2O3 : sinterização, microestrutura e condutividade elétrica protônica
(Universidade Federal de São Carlos, 2015-12-18)
The development of solid electrolytes for Solid Oxide Fuel Cells is a challenge to
enabling this technology as sustanaible energy resource. Ceramics based on
Yttrium doped- Barium cerate are potential candidates for this ...
Desenvolvimento de blendas de TPS, PCL E PLA e seus nanocompósitos com nanowhiskers de celulose de gravatá
(Universidade Federal de São Carlos, 2015-12-15)
The objective of this project was the study of polymer blends of thermoplastic starch (TPS), poly(ε-caprolactone) (PCL) and poly(lactic acid) (PLA) and the extraction of celulose nanowhisker from gravatá (Bromelia balansae) ...
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, ...
Concretos refratários avançados com alto teor de carbono
(Universidade Federal de São Carlos, 2010-03-12)
Refractory castables in the Al2O3-SiO2-SiC-C system are applied in the iron making process, including runners for molten slags and metals. Over the past years, several attempts to increase the carbon content of these ...

Concretos refratários nanoligados para aplicação em unidades de craqueamento catalítico
(Universidade Federal de São Carlos, 2013-09-24)
In the petrochemical industry gasoline and LPG are produced in the fluid catalytic cracking unit (FCCU). The cracking occurs by the contact of crude oil with fluidized fine particles of a ceramic catalyst. The process ...
Sinterização, caracterização e propriedades de compósitos vidro-minerais para uso como revestimentos
(Universidade Federal de São Carlos, 2017-09-06)
Engineered stones, commonly known in Brazil as quartz surfaces, are
materials used as large tiles for application in architecture and interior
decoration. These materials consist of about 90% by weight of mineral ...
Synthesis and characterization of Biosilicate/F18 bioglass scaffolds for dental application
(Universidade Federal de São Carlos, 2019-10-16)
In this work, Biosilicate scaffolds were synthesized using the foam replica technique. Biosilicate is highly bioactive, biodegradable, antibacterial, and non-toxic. Despite of these properties, Biosilicate scaffolds present ...
Influência da adição de um fundente sintético no mecanismo de coloração final de revestimentos cerâmicos
(Universidade Federal de São Carlos, 2011-08-12)
The presence of iron oxide in ceramic tile mass contributes to the reddish color firing of the products leading to a lower aggregate value, not to be regarded as a "noble" ceramic. However, the use of raw materials with ...
