Effect of silica nanoparticles on surface properties, particle size, and distribution of poly (methyl methacrylate-co-butyl acrylate-co-acrylic acid) synthesized by in situ emulsion polymerization

This work concerned synthesis and characterization of an organic water-based coating based on poly (methyl methacrylate-co-butyl acrylate-co-acrylic acid) through seeded semi-batch emulsion polymerization. Silica nanoparticles were added in situ under controlled pH and temperature conditions at different mass concentrations, and…

Early molecular responses of mangrove oysters to nanoplastics using a microfluidic device to mimic environmental exposure

This study assessed the effects of nanoplastics (NPs) using for the very first time microfluidic devices (chip) mimicking transition waters. Three kinds of NPs were tested: crushed NPs from polystyrene pellets (NP-PS), or from Guadeloupe beaches (NP-G); and latex PS…
