Carbon capture: Durable plastic doubles as a cleaner

Melamine, a small aromatic molecule loaded with nitrogen atoms, has traditionally found fame as a tough plastic that is ideal for making durable dishware and laminate coatings. Research by Mei Xuan Tan, Yugen Zhang and Jackie Ying at the A*STAR Institute of Bioengineering and Nanotechnology, Singapore, has shown that this material could play a valuable role in reducing greenhouse gas emissions. They demonstrated that a synthetic procedure turns melamine polymers into low-cost 'scrubbers' that trap and release carbon dioxide (CO2) gas on demand.
