Wu, M., X. Wu, et al. (2011). "Three-dimensional network model of carbon containing only sp2-carbon bonds and boron nitride analogues." Chemical Communications 47(15): 4406-4408.

We design two network models of carbon and boron nitride crystalline networks, namely, the honeycomb and triangular foams. The triangular carbon foam is a unique 3D network model of carbon which contains only sp 2-carbon bonds. Also, it has large internal surface area per unit volume and bulk modulus.
