Credit: Pixabay/CC0 Public Domain The oceans play a pivotal role in drawing down atmospheric carbon dioxide (COâ‚‚) and have so far acted as a brake on the full impact of climate change. Current estimates of the COâ‚‚ from the atmosphere that disappears in the ocean, commonly referred to as the ocean COâ‚‚ sink, suggests that […]
Hydroaminoalkylation enables efficient amine group incorporation into polyethylene, with subsequent conversion to antibacterial ammonium groups. Credit: Saeed Ataie Polyethylene (PE) is one of the most widely used and versatile plastic materials globally, prized for its cost-effectiveness, lightweight properties and ease of formability. These characteristics make PE indispensable across a broad spectrum of applications, from packaging […]
