Rice University Smashing Micro-Cubes at High-Speed for Tougher Nanostructures

Scientists at Rice University are smashing metallic micro-cubes to make them ultrastrong and tough by rearranging their nanostructures upon impact. The Rice team reported in Science this week that firing a tiny, nearly perfect cube of silver onto a hard target turns its single-crystal microstructure into a gradient-nano-grained (GNG) structure. The purpose of the experiment
