  Heat capacity of B2O3 glass former in a wide temperature region is described
well with the intrinsic motions for non-spherical B2O3 molecules, revealing
that rather than a conventional network glass former, B2O3 is a typical
molecular matter in which the transition from liquid to glass in the system
corresponds to the frozen of translational motions for molecules. The finding
might provide an opportunity to understand the mysterious glass transition, as
well as the intrinsic difference between solids and liquids.
