The use of renewable energy such as solar energy to produce hydrogen gas (H2), through the photocatalytic process of breaking the water molecule, is a promising alternative to conventional energy sources. In this context, ...

The tangential microfiltration applied to the clarification of white wine has become an important alternative to conventional filtration processes in the wine industry, for example, the filtration diatomaceous earth, land ...

Este trabalho apresenta um estudo das propriedades mecânicas e tribológicas de compósitos de alumina reforçados com partículas de nióbio obtidos pela técnica de sinterização por plasma pulsado (Spark Plasma Sintering – ...

Control and reduction of friction can help in the elaboration of strategies of energy efficiency and in the reduction of carbon dioxide (CO2) emission. Although there are well established phenomenological laws for friction, ...

Contamination by bacterial biofilms has a strong negative impact, especially when given on the surface of prostheses, implants, pins and other medical-surgical devices. In this study metal samples of Titanium cp and AISI ...

The use of long glass fiber-reinforced thermoplastic composites has increased considerably in the last years. However, the mechanical properties of these materials are strongly dependent on their microstructure (orientation ...
