BORON 2 (IMAGE) Rice University Caption An illustration compares flakes of hexagonal boron nitride, top, and turbostratic boron nitride, bottom, the latter synthesized through the flash Joule heating process developed at Rice University. Two-dimensional materials are turbostratic when interactions between their layers are weak, making them easier to separate and solubilize.
