Hexagonal Boron Nitride Page 9 Long Range Hunting

Oct 29, 2015If bullet BCs could be significantly improved by HBN coating bullets, Sierra, Berger, Barnes, Nosler, Speer and other bullets companies would have been coating their bullets some time ago in order to put the larger BC number on their boxes of bullets. Because the cost to HBN coat bullets isn't all that great. A little HBN powder goes a long ways

For 2-D boron, it's all about that base news.rice.edu

Sep 02, 2015In graphene and boron nitride, atoms settle into flat hexagonal arrays regardless of the substrate. But boron, the researchers found, is the first known 2-D material that would vary its structure based on interactions with the substrate. Perfectly flat boron would be a grid of triangles with occasional hexagons where atoms are missing.

Band gaps in incommensurable graphene on hexagonal boron

Abstract. Devising ways of opening a band gap in graphene to make charge-carrier masses finite is essential for many applications. Recent experiments with graphene on hexagonal boron nitride (hBN) offer tantalizing hints that the weak interaction with the substrate is sufficient to open a gap, in contradiction of earlier findings.
