Efeito do pó de casca de noz pecan nas propriedades de bandas de rodagem de pneus
(2019-09-11)
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 ...
Efeito da estabilização de suspensões de sílica a eficiência de moagem em moinho agitador de esferas
(2019-09-24)
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 ...
Extração, caracterização e utilização de lignina de Eucalyptus grandis na remoção do corante azul de metileno
(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 ...
Influência de moagem de alta energia nas propriedades físicas de uma porcelana de ossos
(2019-11-11)
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. ...
Síntese verde de nanopartículas de prata a partir do extrato do bagaço de Vitis labrusca (cultivar Ives), caracterização e aplicação na desinfecção de efluentes industriais
(2019-03-06)
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 ...
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, ...
