Efeito da calcinação da magnésia precipitada sobre o processamento de cimentos de fosfato de magnésio.
(Universidade Federal de São Carlos, 2004-12-20)
It is great the interest for materials synthesized at room temperature
because they represent an alternative for the current problems of energy. The
class of magnesia phosphate cements belongs to this group, being ...
Desenvolvimento de um detector de espalhamento de luz LASER de baixo ângulo LALLS operando em tempo real na extrusão
(Universidade Federal de São Carlos, 2005-12-08)
In the present work a prototype of a low angle laser light scattering was developed and installed in an extruder in order to operate in real time. The equipment was built by the research group of which the author is member, ...
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 ...
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. ...
Investigação das características de superplasticidade de um aço do sistema Fe-Mn-Al
(Universidade Federal de São Carlos, 2008-02-29)
The alloys of Fe-Mn-Al system have been rather studied in last few years indicating good potential for application, with the benefit of exhibiting 10 to 15% less density, coupled to good performance related to its mechanical ...
Estudo do transporte de íons Li+ em híbrido orgânico-inorgânico (SPHP) e nanocompósito (NHP) e seu desempenho em dispositivos eletrocrômicos.
(Universidade Federal de São Carlos, 2006-08-25)
The main goal of the present work is to describe the lithium ion transport
mechanism in a hybrid (SPHP) and nanocomposite (NHP) polyelectrolyte based
on complex conductivity analysis as a function of temperature. The ...
Processamento do compósito LDPE/Al proveniente da reciclagem de embalagens cartonadas e desenvolvimento de suas modificações com fibras de madeira.
(Universidade Federal de São Carlos, 2006-02-10)
The urban solid waste problem has been one of the biggest
environmental challenges these days. The solution to this problem lies in
integrated waste management, the objective is to minimize volumes sent to
landfills. ...
Caracterização elétrica de eletrólitos baseados em céria Nano e microcristalinos para pilhas a combustível
(Universidade Federal de São Carlos, 2008-09-16)
Fuel cells are considered the most promising way for generating electrical energy in a near future. The economic fuel cells viability is directly related to the reduction of its operating temperature which is related to ...
Seleção de ligas com alta tendência de formação de estrutura amorfa.
(Universidade Federal de São Carlos, 2007-03-08)
The understanding of the law that explain why certain alloys form amorphous
structure by cooling the molten melt under cooling rates lower than others alloys
remains as one of the great challenges of the materials science ...
