Medical infusion bags can release microplastics

Researchers estimate that each bag of infusion fluid could deliver about 7,500 microplastics directly into the bloodstream

14-Mar-2025 - Microplastics have been found almost everywhere that scientists have looked for them. Now, according to research published in the ACS partner journal Environment & Health, these bits of plastic — from 1 to 62 micrometers long — are present in the filtered solutions used for medical intravenous ...

Inspired by the gecko: Better adhesion properties of plastics through combined micro- and nanostructures

Structured surface improves adhesion, wettability, optical reflection, hydrophobicity and recyclability.

27-Feb-2024 - With a patented process for micro-nano-structuring, the Fraunhofer Institute for Microstructure of Materials and Systems IMWS in Halle (Saale) has achieved significant improvements in the adhesion properties of polymers. The process, in which structured surfaces are produced by hot imprinting or ...

Not so silver lining: Microplastics found in clouds could affect the weather

Low-altitude and denser clouds contained greater amounts of microplastics

23-Nov-2023 - From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, in ACS’ Environmental Science & Technology Letters, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could ...

Process converts polyethylene bags, plastics to polymer building blocks

Catalysts disassemble polymer while adding ethylene, producing propylene, the building blocks of polypropylene

03-Oct-2022 - Polyethylene plastics — in particular, the ubiquitous plastic bag that blights the landscape — are notoriously hard to recycle. They’re sturdy and difficult to break down, and if they’re recycled at all, they’re melted into a polymer stew useful mostly for decking and other low-value ...

Microplastic pollution in the Northeast Atlantic: First long-term record from deep water layers of the open ocean

The most common plastic materials were polyethylene and PVC

06-Jul-2022 - Scientists from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) for the first time analysed a long-term sample series on microplastic pollution in the Northeast Atlantic from 2000 m water depth with respect to number, size, mass, material and possible origin of the particles. ...
