Raspberry shaped nanostructures synthesized by a one-pot precipitation method for the photocatalytic degradation of tetracycline and dyes.

Abstract Purpose Carotenoids are potent natural antioxidants with many important applications. Their nanodispersion formulations can solve problems that may limit their usage. In this study, we produced carotenoid nanodispersions from extracted lutein (nano-Lut), β-carotene (nano-EBc), and synthetic (nano-SBC). Methods The present study has quantitatively emphasized the physicochemical, antioxi...

Thermoplastic polymers like polyolefins, polyesters, polyamide, and styrene polymers are the most representative commodity plastics thanks to their cost-efficient manufacturing processes, excellent thermomechanical properties and their good environmental compatibility, including easy recycling. In the last few decades much effort has been devoted worldwide to extend the applications of such mat...

In recent years, improvements have been made, through biotechnological processes, in the production and development of peptides capable increasing collagen elastin synthesis for anti-aging skin care. However, proteins many limitations due to their structural, chemical physical fragility external aggressions, which may cause conformational changes, leading loss biological activity. Therefore, it...

Photocatalytic coatings based on TiO2 nanoparticles have been applied to building materials over the past few decades, following encouraging results obtained by many laboratory studies and a onsite testing campaigns showing their self-cleaning, antimicrobial depolluting performance. However, these clearly point out need for deeper understanding of effectiveness TiO2-based treatments when differ...

OBJECTIVES The development of CAD-CAM techniques called for new materials suited to this technique and offering a safe and sustainable clinical implementation. The infiltration of resin in a ceramic network under high pressure and high temperature defines a new class of hybrid materials, namely polymer infiltrated ceramics network (PICN), for this purpose which requires to be evaluated biologic...
