Estudo do método de mistura das suspensões precipitadas (MPS) para a síntese de catalisadores de tungstênio suportado em zircônia (WOx/ZrO2)
(Universidade Federal de São Carlos, 2017-11-16)
Zirconia-supported tungsten oxide (WOx/ZrO2) is one of the main acid catalysts. The development of new methods for its preparation has been widely studied lately. This thesis presents a study of a new synthesis method, ...
Obtenção e caracterização de nanocompósitos de poliuretano termoplástico reforçado com nanocristais de celulose
(Universidade Federal de São Carlos, 2014-07-15)
In this study the potential of cellulose nanocrystals (CNC) as a
reinforcement of a thermoplastic polyurethane partially obtained from renewable
sources (Bio-TPU) was investigated. The nanocomposites were obtained in ...
Avaliação da durabilidade do concreto utilizado em postes em São Luís
(Universidade Federal de São Carlos, 2016-06-20)
Reinforced concrete structures built in coastal areas, such as electricity distribution poles, are constantly attacked by aggressive environmental agents. Rebar corrosion mechanism is a specific manifestation of electrochemical ...
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, ...
Estudo de elastômeros termoplásticos vulcanizados (TPVs) de borracha natural e polipropileno
(Universidade Federal de São Carlos, 2015-12-21)
Natural rubber (NR) is used for the preparation of several articles in domestic, industrial and automotive worldwide. However, for the NR can be used in these applications it must be vulcanized hindering their recyclability, ...
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 ...
