—Eliminating Ethylene “Platinum nanoparticles on mesoporous silica oxidize fruit-ripening gas at low temperatures” Fruits, vegetables, and flowers release the growth-regulating plant hormone ethylene, which in turn accelerates their aging, causing them to release more of the volatile two-carbon compound. Left unchecked, a trace amount of ethylene can lead to spoiled produce, even in a refrigerated container. Chemists at Japan’s Hokkaido University are now offering a nanoscale solution. Atsushi Fukuoka, Chuanxia Jiang, and Kenji Hara show that platinum nanoparticles supported on mesoporous silica readily oxidize ethylene (Angew.
