Researchers use nanomaterials to make 2D diamond clusters at room temperature

BROOKLYN, New York, Monday, January 26, 2021 – Atomically thin, 2D hexagonal boron nitride (h-BN) is a promising material whose protean ability to undergo phase transformations to strong, super lightweight, chemically stable, oxidation-resistant films makes them ideal for protective coatings, nanotechnology thermal applications, deep-UV light emitters, and much more. The possibilities embodied in different polytypes […]
