The quest to create superhard materials rarely strays from the use of high-pressure synthetic
methods, which typically require gigapascals of applied pressure. We report that rhenium …

Dense transition metal borides have recently been identified as superhard materials that
offer the possibility of ambient pressure synthesis compared to the conventional high …

B6O is a possible candidate as a superhard material with a hardness of 45GPa measured
on single crystals. The first dense superhard B6O-materials were produced under high …

Angle-dispersive synchrotron X-ray diffraction measurements were performed on vaterite-
type YBO 3/Eu 3+, GdBO 3, and EuBO 3, respectively, up to 41 GPa at room temperature …

Superhard materials are usually composed of light elements such as boron, carbon,
nitrogen, and oxygen. These light elemental atoms have the ability to form covalently …

DISCUSSION Metal borides possess many remarkable mechanical, 1–4 optical, 5 magnetic,
5 and thermal 6 properties. Among the mechanical properties, hardness, and …

DOI: 10.1002/adma. 201604003 high electrical conductivity has been an urgent task, calling
for more experimental effort along this direction. During last decade, the borides of transition …

This article summarizes the developments of experimental techniques for high pressure x-
ray diffraction (XRD) in diamond anvil cells (DACs) using synchrotron radiation. Basic …

We report an approach to strengthen micro-grained polycrystalline diamond (MPD) compact
through work hardening under high pressure and high temperature, in which both hardness …

Abstract High-purity (Ta 0.2 Nb 0.2 Hf 0.2 Zr 0.2 Ti 0.2) C high-entropy ceramics are
successfully synthesized using high-pressure solid-phase reactions. The high-entropy …
