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 ...

Due an annually increase of polymer production, lots of residues are being generated and recycled by low technology investments and it is used to produce simple material, as bags and containers. However, engineering polymers ...

The using of a nonrenewable resources in the production of new materials, in particular synthetics plastics, it is a cause for concern and environmental call ones due to its long degradability time. Although a lot of ...

A few years ago, several studies have been conducted to transformatio n of raw matter into renewable biodegradable materials, since it is necessary to rethink consumption and rationalize the use ...

Currently, seek to technologies for new materials that minimize environmental problems, it leads researchers to develop polymers from renewable and biodegradab le sources, such as cellulose and ...

The processes of separation and isolation of Kraft lignin obtained have been insufficiently resear ched, since much of the lignin of liqueurs obtained industrially is burned for energy recovery ...

In a technology-driven society, the increase of electrical and electronic equipment consumption has been a matter of concern in relation to its management, since the expectation is that the quantity of electrical and ...

This work focuses on the production of nanostructured films of poly (ethyleneimine) PEI together with MAO-b free and encapsulated in liposomes constructed by the layer-bylayer technique (LbL), for application in biosensors. ...

The industrial waste usage for technological application has been gaining ground in different segments and applications. One of the prominent sectors is Material technology, where these residues can be used to obtain the ...

Among the polymers widely investigated as materials for tissue engineering, polyurethane has its place of prominence, mainly due to the high flexibility and tenacity. The need for devices with certain mechanical properties ...
