Nowadays, cosmetic fillers are widely used and the reports of complications are rising. Therefore, the possibility to detect and identify noninvasively new fillers can provide a potent tool for managing complications. The ...

Poly[N-(2-hydroxyethyl)-beta-propylamide] oligomer is syntehsized using a simple enzymatic procedure involving Candida antarctica lipase B. This novel compound is obtained by a green and chemoselective method from economic ...

The incorporation of fibers as reinforcements in polymer composites has increased due to their renewability, low cost and biodegradability. In this study, sisal fibers were added to a polymer matrix of thermoplastic starch ...

In the present study, polyurethane materials were obtained from castor oil, polycaprolactone and isophorone diisocyanate by incorporating different concentrations of chitosan (0.5, 1.0 and 2.0% w/w) as an additive to improve ...

In this work different phenomena related to sorption of carbon dioxide in polycaprolactone (PCL) have been investigated systematically. The use of compressed carbon dioxide is discussed for obtaining porous scaffolds from ...

Thermoplastic starch (TPS)/polycaprolactone(PCL) blends were obtained by melt mixing. First, thebest formulation of thermoplastic starch (starch, plasticizerand additives) was studied. The obtained filmswere characterized ...

Thermal degradation processes for a series of mixtures based on polycaprolactone (PCL), with microcrystalline cellulose (MC) and sisal fiber (SF) powder, were investigated by thermogravimetric analysis (TGA), in order to ...
