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 ...

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 ...

Hydrogel controls cell growth outside the body

Chemists at Radboud University discovered a unique material in 2013. From a synthetic polymer named polyisocyanopeptide (PIC), they made a gel that behaves similar to the matrix that surrounds the cells in your body. The ...

Artificial cells act more like the real thing

Protocells—artificial cells—that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers.
