Abstract:
A team led by Carnegie s Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic and energy devices with enhanced properties that exceed those of the normal cubic form of silicon used today. ....

For most of human history, diamonds have been the ultimate luxury item. Diamonds are beautiful, rare gemstones naturally formed at about 150 kilometers deep within the earth s mantle billions of years ago. The diamond formation process usually begins after an incredible amount of heat, above 1,000 degrees Celsius, and massive pressure from rocks crush the carbon buried deep beneath the earth s surface. This process causes the carbon to crystallize into a diamond instead of graphite. It is that crystalline structure that gives diamonds their durability and immense value.  Some diamonds have also been produced as a result of meteor impacts, as long as there is the combination of heat, pressure and carbon present.  ....
