Three-dimension (3D) porous reduced graphene oxide (RGO) scaffold has attracted increasing attention in bone tissue engineering due to its favorable osteoinductivity. In this paper, a 3D porous RGO composite was prepared from graphene oxide (GO) and nano-hydroxyapatite (nHA) via self-assembly, thus constructing biomimetic scaffold for bone defect reparation. Detailed studies were performed to evaluate...
The electronic structures of pure and boron-doped graphene layers have been investigated using the semi-empirical Molecular Orbital Package (MOPAC) and large clusters of carbon atoms. It is shown that boron-doping on the edge and internal lattice sites of the graphene layer produces very different effects on the electronic structure around the edges. It is found that the substitutional boron atoms...
