While attention on the importance of closing materials loops for achieving circular economy
(CE) is raging, the technicalities of doing so are often neglected or difficult to overcome …

In this review, traditional and novel techniques for producing micro-and nano-fibers are
discussed and various nanofillers, their modifications and polypropylene (PP) …

This paper presents the reuse process of post-consumer printed foils made of glycol-
modified poly (ethylene terephthalate)(PETG). Fourier-transform infrared spectroscopy and a …

In this work, we used a simple accurate method to measure the short temporal coherence
length of a light emitting diode. This method is based on accurate visibility determination of …

Optical fibers are extensively used in modern technology such as sensing, shortdistance
and long-distance telecommunications. This motivated many researchers to present different …

Recent developments in functional materials are creating the attention on global
environmental concerns and economical impact, in this scenario the development of …

Composites are materials made from two or more constituent materials with significantly
different physical or chemical properties. The two materials combine together to give a new …

Implementation of material value conservation (MVC) needs to be proven through research
to determine impact upon plastic properties such as optical properties of virgin plastic and …

Os materiais poliméricos trouxeram não apenas uma série de vantagens para o ser
humano, mas também, infelizmente, alguns graves problemas ambientais. Logo é …
