The use of natural organic materials in polymer products has attracted great attention in recent years due to economic, environmental and reduction dependence on petroleum based products. In this context, this work aims ...

The milling of ceramic particles in water suspensions in stirred media mills is a high energy process indicated to obtain materiais in submicron and nanometric scales, and is presented as an alternative to chemical processes ...

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 ...

Porcelain made from bovine bone ashes, known as bone china, is whiter, lighter, stronger and more translucent than ordinary porcelain. The strength of a bone china can reach up to twice the resistance of common porcelain. ...

Traditional methodologies for the synthesis of metallic nanoparticles include the use of toxic chemicals that can have negative impacts on the environment and human health. Thus, a safer alternative to the production of ...

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 ...

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 ...

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, ...
