Sinterabilidade, desenvolvimento microestrutural e caracterização elétrica do BaCe0,9Y0,1O3-ẟ nanométrico obtido por mistura de óxidos
(Universidade Federal de São Carlos, 2018-11-28)
In this thesis, we investigated the microstructural development of BaCe0,9Y0,1O3-ẟ starting from aggregate-free submicrometric and nanometric powders. The differential of these powders is that synthesis occurred via ...
Estudo dos efeitos da substituição de Feldspato por Filito em massas de porcelanato
(Universidade Federal de São Carlos, 2018-11-21)
Porcelain stoneware tiles, porcelanatos, present excellent technical and aesthetic characteristics. In Europe, the bodies used in the manufacture of porcelain and porcelanatos are based on the classic triaxial ceramic, ...
Seleção de aditivos de sinterização e processamento cerâmico visando otimização da microestrutura do eletróllto sólido BaZr0,8Y0,2O3-δ
(Universidade Federal de São Carlos, 2018-11-12)
In this thesis, we investigated the production of Yttrium-doped Barium Zirconate
proton-conducting electrolytes with 20 at.% of Yttrium (BaZr0.8Y0.2O3-δ) via solid state
reaction. The great challenge presented by this ...
Nano céria dopada com gadolínia: condutividade elétrica e correlação com a micro e nanoestrutura
(Universidade Federal de São Carlos, 2013-04-11)
Solid Oxide Fuel Cells (SOFCs) are clean and efficient energy conversion devices, considered as one of the key enabling technologies for future hydrogen economy and for stationary power generation. However novel materials ...
Comportamento em fadiga da liga Ti-6Al-4V para uso biomédico com superfícies modificadas
(Universidade Federal de São Carlos, 2011-09-09)
Surface modification in implants is used, basically, to improve osseointegration, which is defined as the intimate contact between bone and implant material, without a soft tissue layer in the bone/implant interface. ...
