Solid gold

Stabilizing gold clusters so that they can grow into perfectly formed nanoscopic polyhedral is now possible thanks to research in Singapore. The unique polyhedra have energy-rich surfaces that can boost the catalytic efficiency of important chemical reactions and serve as potential adsorption sites for targeted sensor devices. Yong-Wei Zhang from the Institute of High Performance Computing and Ming-Yong Han from the Institute of Materials Research and Engineering at A*STAR and colleagues report details in the journal Advanced Materials.
