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

Atomically thin, 2-D 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.
