Shahsavari’s had already determined through computer models how tough and resilient pillared graphene structures would be, and later ed boron nitride nanotubes into the mix to model a unique three-dimensional architecture. (Samples of boron nitride nanotubes seamlessly bonded to graphene have been made.)
Jun 15, 2018· 1. Introduction. While the atomic structures of 2D materials such as graphene and boron nitride, with a 2% latt mismatch in the interface in the newest syntheses of these materials, have attracted the attention of researchers, the combination of these two materials by means of sturdy interfaces or connections can lead to even more interesting functional properties .

May 27, 2011· Graphene, the two-dimensional honeycomb of carbon just one atom thick, is so sensitive to its environment that its remarkable electronic properties can be wrecked by interference from nearby materials. If graphene devs are ever to become practical, finding good substrates on which to mount graphene is critical. A team of researchers from Berkeley Lab and UC Berkeley have shown why boron
B-doped graphene nanoplatelets prepared at 1000 °C show a maximum boron concentration of 6.04 ± 1.44 at %, which is the highest value among B-doped graphenes prepared using various methods.

We determine the electronic structure of a graphene sheet on top of a latt-matched hexagonal boron nitride (h-BN) substrate using ab initio density functional calculations.
A series of boron-doped graphene-supported Pt (Pt/BG) nanosheets were designed and synthesized using a one-step facile hydrothermal method. ICP, XPS, and TPD results confirmed that boron atoms were successfully embedded into the graphene matrix. The selective catalytic reduction of nitric oxide with hydrogen (H 2-SCR) was tested over Pt/BG
