Under pressure, carbon dioxide mimics glass
Carbon, a multitalented element, has yet another trick to boast of. Researchers at the European Laboratory for Nonlinear Spectroscopy and the National Institute for the Physics of Matter, both in Italy, have coaxed carbon dioxide into forming glass at room temperature and high pressures (Nature 2006, 441, 857). In the newly synthesized solid, dubbed amorphous carbonia, or a-carbonia, the molecules form a three-dimensional interconnected network, similar to silica glass. The substance is very . . .
