In the 2013/14 harvest, Brazil produced 751,000 tons of tobacco leaves. Tobacco industry employs tobacco leaves for cigarette and cigar production. About 4% of the tobacco leaves processed become a waste, which is basically ...

Glass foams are heterophasic materials applied in acoustic and thermal insulation, and compared to other materials, are lightweight and sturdy. Glass foams can be prepared from glass packaging, cathode ray tubes and other ...

Within this context, this work aims to prepare membranes composed of α-alumina coated with palladium using the electroless plating technique associated with the sol-gel method. To achieve the objectives of the paper, ...

Composites are materials composed of two or more different materials, forming a heterogeneous class of materials which differ in physical and chemical properties. Recent studies on biodegradable polymer composites reinforced ...

Expanded composites or vegetable fiber-reinforced cell composites are a new emerging class of materials combining good mechanical properties of reduced density, having superior ability of energy absorption at impact, as ...

In recent years, renewable energy has received increased importance due to increased anthropogenic emissions of greenhouse gases to the atmosphere. Biomass is a promising renewable resource for the production of energy. ...

The environmental impact caused by improper disposal of packaging materials based on synthetic polymers, arouses interest in development packaging from biodegradable materials. The objective of this study was to develop ...

The search for low-impact, renewable materials is a recent research topic. The need to substitute materials from non-renewable sources is one of the main motivations for such studies in this area. In this context, one of ...

This work aimed at the development, evaluation and characterization of polymer matrix composites with high density polyethylene (HDPE) and wood of Pinus taeda, calcined alumina and compatibilizers. Composites have been ...
