Traditional glass molding involves infrared heating; however, the thermal cycle time is long. A molding technique based on three-dimensional carbide-bonded graphene (CBG) has been developed to mold boron silicon glass. This CBG coating on a wafer silicon die can serve as a thin-film resistance heater to heat up the sample surface very rapidly with a relatively low applied voltage.

Monolayer graphene exhibits extraordinary properties owing to the unique, regular arrangement of atoms in it. However, graphene is usually modified for specific applications, which introduces disorder. This article presents details of graphene structure, including sp hybridization, critical parameters of the unit cell, formation of σ and π bonds, electronic band structure, edge orientations, and the number and stacking order of graphene layers.
