Diamond holds up at pressures more extreme than those in Earth’s core

Diamond

Diamond stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report January 27 in Nature. The study suggests that diamond is metastable at high pressures: It retains its structure despite the fact that other, more stable structures […]

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 […]

Stretching diamond for next-generation microelectronics — ScienceDaily

Diamond is the hardest material in nature. But out of many expectations, it also has great potential as an excellent electronic material. A joint research team led by City University of Hong Kong (CityU) has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach. Their […]
