Silver is an element with widely recognized bactericidal activity. Its use in the modification of materials has been studied for decades and its use goes through different forms of incorporation in the matrices of interest, ...

The proper disposal of solid waste has driven studies to enable the use of recycled materials and waste. So, in this work were molded composites using raw materials from industrial waste and evaluated several mechanical ...

One of strong associations between polymers as biomaterials are in field of skin reparation. Polymers are utilized for this purpose, some such as poly (vynil alcohol) (PVA) are used due to characteristics such as ...

Issues related to renewable energy have been increasingly addressed and discussed. In this context, biomass is an alternative for the generation of renewable and available energy. Its use, instead of fossil fuels, helps ...

Polypropylene (PP) is a polymer used industrially on a large scale. However, the PP has limitations in external use due to its sensitivity to photodegradation, when exposed to the elements. This limits the options of use ...

The present study aimed to obtain functionalized nanocellulose through the oxypropylation reaction. Thereunto, the cellulose was submitted to an initial activation step with a sodium hydroxide solution, and then the reaction ...

Interest in the use of starch for biodegradable films is growing due to being a natural, renewable, abundant and low cost source. However, starch films generally have low values of mechanical properties. Thus, this work ...
