Identificação de um modelo constitutivo para simulação computacional do processo de prensagem a frio de um material refratário sílico-aluminoso
(Universidade Federal de São Carlos, 2016-08-05)
One of the methods for the processing of refractory material is cold pressing of the powder material, followed by sintering. Heterogeneous distribution of density can occur in the green compact during pressing because of ...
Reaproveitamento de resíduos da agroindústria da laranja para a produção de compostos biodegradáveis em matriz de PBS
(Universidade Federal de São Carlos, 2021-09-24)
The employment of biodegradable polymers is a partial solution to the problem of environmental plastic pollution, since conventional polymers are resistant to many environmental influences and it may take centuries for ...
Moagem de alta energia e deformação plástica severa do Mg e do Mg-Fe na síntese de hidretos para armazenagem de hidrogênio
(Universidade Federal de São Carlos, 2017-03-04)
Magnesium is a light metal with a relatively low cost. It can form magnesium hydride (MgH2), which is interesting for the safe storage of hydrogen in the solid state, thanks to its high gravimetric capacity of 7.6%. The ...
Comportamento mecânico de poli(éter-éter-cetona) revestida com hidroxiapatita por aspersão plasma para uso em implantes cirúrgicos
(Universidade Federal de São Carlos, 2015-12-10)
The remarkable advances in scientific research of materials for ever demanding service requirements has led to novel developments of biomaterials, especially in the field of surgical implants. In this field, the semi-crystalline ...
Desenvolvimento de cimentos ósseos à base de Biosilicato
(Universidade Federal de São Carlos, 2020-03-27)
Synthetic grafts have an important contribution to modern health care, especially in bone reconstruction surgeries. In addition orthopedics, bone grafts can also be used in maxillofacial surgery. In 1980s, bone cements ...

(Universidade Federal de São Carlos, 2004-09-27)
The present study has the purpose of identifing and analysing the tendencies of vehicle recycling technologies focusing on shredder residue, PVC and heavy metals due to the importance of this area to the development ...
Influência da incorporação de aditivos nas propriedades do Poli (Hidroxibutirato-co-hidroxivalerato) - PHBV
(Universidade Federal de São Carlos, 2008-08-05)
The concept of environmentally correct products has been exhaustively discussed and, today, the use of biodegradable polymers appears as a feasible alternative for the problem of inadequate disposal of plastic waste products. ...
Condutividade elétrica da solução sólida céria-zircônia dopada com ítrio e gadolínio
(Universidade Federal de São Carlos, 2009-09-10)
Rare earth doped ceria has a great potential to be used as electrolyte in temperatures around 800 °C in fuel cells due to its higher electrical conductivity than YSZ. However, the reduction of Ce+4 to Ce+3 in low oxygen ...
Situação atual e perspectivas de utilização de materiais no interior de aeronaves executivas
(Universidade Federal de São Carlos, 2009-08-04)
This study focuses on analyzing the current situation and perspectives of materials selection and utilization, like composites, decorative laminates and films, and others, in business aircraft, particularly in furnishings ...
Grau de cisão de cadeia na degradação termomecânica de polímeros sob multiplas extrusões
(Universidade Federal de São Carlos, 2004-09-14)
One of the ways to follow the polymer degradation has been to calculate the average number of chain scissions (ns) that occurred during its
thermomechanical history. The average can be extended for each molecular weight ...
