janus zeal writes "A form of solid carbon dioxide that could be used to make ultra-hard glass or coatings for microelectronic devices has been discovered. The material, named amorphous carbonia, was created by scientists from the University of Florence in Italy. Writing in the journal Nature, the team says the material was theoretically possible but had never been created. It was made by squeezing dry ice, a form of carbon dioxide used to create smoke in stage shows, at huge pressure. Scientists are interested in the new material because of the potential applications. Also, they believe it could give them clues to the processes that happen in the center of huge gas giant planets such as Jupiter."
