Estudo de filmes de poli(ácido lático) obtidos por fiação por sopro em solução reforçados com nanocristais de celulose
(Universidade Federal de São Carlos, 2016-07-15)
Solution blow spinning is a technique to produce micro- and nano-scale fibers, forming films with high porosity and surface area. Chemical modifications or the incorporation of nanostructures in these fibers can improve ...
Avaliação da resistência à fadiga e caracterização microestrutural de fios extrudados e forjados da liga AA7050 reciclada por conformação por spray
(Universidade Federal de São Carlos, 2016-12-19)
High strength 7XXX precipitation hardened aluminum alloys are widely
used in aircraft structural components. The machining process applied in the
fabrication of these components is a low efficiency ...
Síntese in situ pelo método Pechini de compósitos magnetoelétricos SBN/NFO para o controle do crescimento anormal dos grãos da fase SBN
(Universidade Federal de São Carlos, 2016-10-19)
A study was made of the synthesis and processing of magnetoelectric particulate composites of strontium barium niobate (SrxBa1-xNb2O6, or simply SBN) as a lead-free piezoelectric phase and nickel ferrite (NFO) as a magnetic ...
Efeito do envelhecimento em baixa temperatura nas propriedades de aços inoxidáveis lean duplex
(Universidade Federal de São Carlos, 2016-03-23)
In this work, the mechanical and corrosion properties of two lean duplex steels
(LDSS) 2101 and 2404 aged at 475 °C for up to 2000 h were assessed, and the
obtained results were compared with the standard duplex stainless ...
Estudo da resistência à fadiga da liga Ti-6Al-4V com superfície modificada por tratamento químico
(Universidade Federal de São Carlos, 2016-03-22)
Chemical surface treatments (CST) in cementless and endosseous
implants are used to increase the implant-bone contact area, reducing the period
of osseointegration and favouring bonding ability between implants and ...
Indicadores do patenteamento de materiais armazenadores de hidrogênio voltados para o monitoramento tecnológico
(Universidade Federal de São Carlos, 2016-05-13)
Hydrogen is considered the energy carrier of the future, due to its high energy content and the possibility of its sustainable production. However, its broader implementation depends on overcoming of several technological ...
Resistência à fadiga de junta circunferencial de um tubo API 5L x 70 em contato com etanol
(Universidade Federal de São Carlos, 2016-09-19)
Circumferential field-welding joints of oil pipelines are susceptible to defects that may lead to failures when in operation. The type of product to be transported is an important factor in the evaluation of environment-induced ...
Obtenção e caracterização estrutural, microestrutural e elétrica do condutor protônico BaCe1-xYxO3-δ com e sem aditivo de sinterização
(Universidade Federal de São Carlos, 2016-12-19)
The study of solid electrolytes (SE) is important to the scientific and technological development of materials used in application related to clean energy generation, such as Solid Oxide Fuel Cells (SOFCs). Yttrium-doped ...
Controle da hidratação do óxido de magnésio: fundamentos físico-químicos e aplicação tecnológica
(Universidade Federal de São Carlos, 2016-08-24)
Magnesium oxide has been proposed as an alternative binder to calcium aluminate cement in refractory castables with reduced amount of CaO. The binding effect is generated by the MgO hydration, resulting in brucite [Mg(OH)2]. ...
