Diamond-like carbon (DLC) coatings combine high wear resistance and low friction coefficient. Due to these properties, DLC can be applied on metal parts to facilitate the conformation process in bending tools and also for ...

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, ...

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, ...

Surfaces interactions dominate the properties of colloidal particles suspension. The balance between surface, solvent, and active species in solution determines the properties related to the solid-liquid interface interactions ...

The supply and access to drinking water is one of the great challenges of this century. In this perspective, the rapid advancement of Nanotechnology has contributed significantly to the development and production of ...

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 ...
