(Universidade Federal de São Carlos, 2018-09-10)
The research based on ionic conductive ceramics is part of the scientific innovation efforts applied to the industry of solid state batteries and sensors, which are fundamental for the development of new, more efficient ...
Preparação, caracterização e otimização de biocompósitos poliméricos comestíveis reforçados com fibras vegetais
(Universidade Federal de São Carlos, 2017-05-19)
The ever-growing environmental concern arising from the unrestricted exploitation of fossil raw materials for the massive production of non-biodegradable materials, guided by the rapid increase in the world population as ...
Vitrocerâmicas condutoras de íon lítio com estrutura do tipo Nasicon baseadas no sistema Li1+X CrX (GeY Ti1-Y)2-X (PO4)3
(Universidade Federal de São Carlos, 2018-03-22)
The primary goal of this work is to develop a new NASICON-structured glass-ceramic with high
Li-ion conductivity. Therefore, this work introduces a new series of NASICON-type compositions
based on the Li1+xCrx(GeyTi1-y)2-x(PO4)3 ...
Microestrutura e propriedades mecânicas da liga AA6061 processada por deformação plástica severa em temperatura criogênica
(Universidade Federal de São Carlos, 2017-08-08)
The present work aimed two fronts: to characterize the mechanical behavior of the AA6061 alloy at cryogenic temperature, and to study the microstructural and properties evolution after cryogenic severe plastic deformation. ...
Desenvolvimento de novas ligas quasicristalinas à base de alumínio
(Universidade Federal de São Carlos, 2018-03-21)
Quasicrystalline phases are known for presenting particular crystallographic characteristics that make them a separate group of solid materials. Most of these phases are Al-based and they form in compositions near complex ...
