(Universidade Federal de São Carlos, 2022-03-04)
In the last two decades, tungsten oxide (WO3) has been a target of the scientific and technological interest community due to its optical and magnetic properties, which finds important applications such as sensors, ...
Desenvolvimento e caracterização de biocompósitos de blendas TPU/PCL com hidroxiapatita para produção de scaffolds bioativos via impressão 3D
(Universidade Federal de São Carlos, 2022-08-02)
The increasing need for biological tissues to treat defects caused by disease or injury has demanded new solutions to provide functional substitutes that supply tissue shortages and suit the needs of each patient. In this ...
Desenvolvimento de compósito epóxi/fibra de vidro produzido por enrolamento filamentar para revestimento interno de coluna de produção de petróleo em aço carbono na exploração offshore
(Universidade Federal de São Carlos, 2021-08-04)
Epoxy/glass fiber composites (GRE) were produced by filament winding with a view to application as a liner in a carbon steel tube to replace all-metal super duplex stainless steel column in offshore petroleum exploration. ...
Descrição termodinâmica via CALPHAD do líquido super-resfriado no Sistema Mo-Nb-B com o modelo de 2-Estados
(Universidade Federal de São Carlos, 2021-08-12)
In the present work, we will use the Thermo-CalcTM software to model
with the CALPHAD method the super-cooled liquid (SCL) that leads to the

Atomização a gás do aço ferramenta A2: efeito dos parâmetros de processo nas características do pó
(Universidade Federal de São Carlos, 2022-03-23)
Gas atomization is the main method in powder metallurgy to produce powders for additive manufacturing (AM). The gas atomization process allows generally spherical and very fine metallic powders with great yield on the ...
Avaliação das propriedades de armazenagem de hidrogênio através de reação sólido-gás e eletroquímica da liga multicomponente (TiNb)(CrMnFe)₂ com estrutura de Fase Laves tipo C14
(Universidade Federal de São Carlos, 2023-02-24)
Hydrogen is critical for storage and transport of renewable energy. Because it is low-density gas, one of the biggest challenges of its widespread use as an energy vector is in its hardly storage. Metal hydrides are strategic ...
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 ...
