Abstract Effect of titania nanoparticles modified with 3 wt% [3‐(methacrylloxy)propyl]trimethoxysilane (m‐TiO 2 NPs) and zirconia (3‐glycidyloxypropyl)triethoxysilane (m‐ZrO on properties morphology acrylic emulsion polymer coating was investigated. With suitable weight ratio m‐TiO /m‐ZrO NPs, the could be improved abrasion resistance, weather durability, reflectance index (400–1400 nm) as well...

Itaconic acid (IA) is a well-known bio-based monounsaturated organic (C5H6O4), with white color and crystalline structure. It widely used in the agro-based, plastics, textile, paint pharmaceutical sectors, owing to its flexible structure, due presence of functional groups covalent double bonds. IA an alternative petrochemicals acrylic methacrylic acids. Commercial manufacturing using Aspergillu...

Emulsion polymerization is considered a safe, economic, versatile, and consequently of interest as an environmentally friendly process. However , surfactants utilized need to be biodegradable , and still guarantee a good film quality , with an adequate performance according to its end use. We investigated the substitution of an alkyl phenol ethoxylated (APE) surfactant ,commonly for a sulfosucc...

Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation top predators such as cetaceans still lacking. This study investigates microplastics in intestinal samples from harbour porpoises ( Phocoena phocoena ) found along the coastline of Schleswig-Holstein (Germany) between 2014 2018. Out 30 individuals North...

The influence of polluting gases on the stability polymeric films has not been studied extensively. In fact, chemical interactions such materials in contact with ambient atmosphere depend different factors as environmental conditions, manufacturing process product, presence additives or various pigments. this study, accelerated artificial gas ageing was carried out. experiments were performed a...

Ocular prostheses are important determinants of their users' aesthetic recovery and self-esteem. Because of use, ocular prostheses longevity is strongly affected by instability of the iris color due to polymerization. The goal of this study is to examine how the color of the artificial iris button is affected by different techniques of artificial wear and by the application of varnish following...
