Gold nanoparticle (AuNPs) functionality has been highlighted in several areas of knowledge in recent decades, including diagnostics, where factors such as dispersion and stability are directly related to the test performance, ...

The worldwide solid waste composition indicates that polymeric materials account for, approximately, 10% of municipal solid waste (MSW). The MSW after sorting still contain a plastic fraction (FPR) made of recyclable waste, ...

The growing global energy demand and concerns regarding the availability of fossil fuels are among the most discussed issues in the 21st century. These issues encourage research into the development of renewable energy ...

The production of cellulases is of major interest in order to increase economic viability of second generation ethanol. This complex contains three major enzymes: endoglucanases, exoglucanases and β-glucosidades. Filamentous ...

Different carbon sources have been used in fermentation processes for 2,3-butanediol (2,3- BDO) and acetoin (acetyl methyl carbinol; AMC) production. These substrates can be obtained from agro-industrial by-products, ...

Sanitary landfills of urban solid waste generate large quantities of leachate, effluents with high concentrations of pollutants. So, it is necessary to study processes to treat this effluent in an effective way. This study ...

Magnetoelastic alloys can be used as sensors because they do not require direct electrical connections, which facilitates their use in different media. However, the ease of alloys to undergo oxidation due to the high ...
