New study expands the scope of aza-Friedel–Crafts reactions

From life-saving drugs and synthetic polymers to diverse advanced materials, the products containing organic compounds seem endless, thanks in part to regioselectivity, a feature in chemical reactions where a substituent ...

Unusual interactions between polymers explain hydrogel formation

Many people use hydrogels without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes jelly-like, but it does not wet. Some people place ...

Squid tissues and chemistry combine for versatile hydrogels

Researchers at Hokkaido University in Japan have combined natural squid tissues with synthetic polymers to develop a strong and versatile hydrogel that mimics many of the unique properties of biological tissues. Hydrogels ...

New upcycling system for commercial polyesters

While plastics or synthetic polymers have many useful properties, their mismanagement has resulted in widespread pollution that chokes up our ecosystems. As a solution to this, many synthetic polymers are sent for reprocessing ...
