principle ...
Nível de degradação termomecânica e coleta de compostos orgânicos voláteis durante a extrusão de polímeros
(Universidade Federal de São Carlos, 2008-12-01)
In this work we studied the thermomechanical degradation and volatile organic compound (VOC) generated during extrusion of the HDPE, PP, and PS. The degradation processes occurred during extrusion were analyzed by a new ...
Caracterização estrutural e elétrica de óxidos semicondutores do tipo espinélio.
(Universidade Federal de São Carlos, 2002-10-14)
Desenvolvimento de um equipamento para avaliar propriedades elásticas de cerâmicas refratárias a altas temperaturas pelo método de ressonância de barras.
(Universidade Federal de São Carlos, 2002-09-12)
The knowledge of the elastic properties has been of fundamental
importance for the understanding of the limitation of the useful life of structural
refractory ceramics. Those properties characterize the elastic rigidity ...
Desenvolvimento de nanocompósitos à base de Mg armazenadores de hidrogênio processados por moagem de alta energia.
(Universidade Federal de São Carlos, 2003-10-29)
In the present work, Mg based nanocomposites were developed in the following systems: Mg TM, MgH2 TM, MgH2 MgF2 e MgH2 TM MgF2

energy ...
Processamento e caracterização de condutores de íons O2- a partir de cerâmicas BIMEVOX.
(Universidade Federal de São Carlos, 2005-11-11)
In this work, the processing of BIMEVOX family ceramics (ME-doped bismuth vanadate, ME =Cu2+, Fe3+ and Ti4+), obtained by precursor oxides fusion method was studied. The resulting powders were valued by X ray diffraction, ...
Determinação da energia de fratura em materiais cerâmicos em altas temperaturas.
(Universidade Federal de São Carlos, 2005-03-11)
In this work, the main objective was to determine the energy of fracture in
ceramic materials, focused on refractories, at high temperatures and to inquire
the interference of the creep on this measurement. Therefore, ...
Processamento viscoplástico e conformação cerâmica por rolos a frio a partir de suspensões concentradas de alumina.
(Universidade Federal de São Carlos, 2005-07-27)
Plastic forming, followed by roll-pressing, allows to shape ceramic bodies with thickness that are useful for electronic and pavement ceramics. This work introduces an alternative route to processing ceramic plastic mixes. ...
