Abstract

Abstract : In article number 2004695, Dougal McCulloch and co‐workers report the synthesis of nanocrystalline diamond from a compressed graphitic precursor at room temperature in a diamond anvil cell. Diamond is one of the most important materials for 21st century technology, but there is much that is still not understood about how it forms. This article shows how the presence of shear at high pressures leads to the formation of both regular cubic diamond and hexagonal diamond (Lonsdaleite) without heating.
