Glass under Pressure

Caption: Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now researchers at UC Davis have for the first time captured atoms in borosilicate glass flipping from a flat triangular configuration with three oxygen atoms around one boron to a tetrahedron, via a pyramidal intermediate.
