(2019-10-28)
In the last decades, environmental problems have become increasingly critical and frequent mainly due to excessive population growth and increased industrial activity. The textile sector stands out in this scenario for ...
A adsorção de tióis monitorados pelo método de voltametria cíclica com uso de eletrodos de ouro
(2019-08-15)
In this work, the application of amorphous magnetoelastic alloy coated with gold by magnetron sputtering and electroless methods is demonstrated. The thickness, delamination, and roughness evaluations of the gold coatings ...
Influência do inibidor de pré-vulcanização nas propriedades de composições de borracha natural não vulcanizadas
(2019-12-16)
Vulcanization is a crosslinking process in which the chemical structure of the elastomer is changed by the interlinking of the long chains of the polymer, resulting in a three-dimensional network. The tire repairing industry ...
Interações de van der Waals na superlubricidade de filmes nanoestruturados e hidrogenado
(2019-03-26)
Friction is originated by energy dissipation events owing to the lost work of non-conservative forces. The nanotribological mechanisms through which this dissipation can occur include molecular deformation and thermal, ...
