Excellent hardness property of bulk MoN fabricated by a novel method

open access: yesResults in Physics, 2020
Molybdenum nitrides (MoNs) are important materials for their excellent physical and chemical properties, but synthesizing stoichiometric and bulk materials is still a great challenge.

Synergy of atom-probe structural data and quantum-mechanical calculations in a theory-guided design of extreme-stiffness superlattices containing metastable phases

open access: yesNew Journal of Physics, 2015
A theory-guided materials design of nano-scaled superlattices containing metastable phases is critically important for future development of advanced lamellar composites with application-dictated stiffness and hardness.

Compressibility and structural stability of ultra-incompressible bimetallic interstitial carbides and nitrides [PDF]

open access: yes, 2012
We have investigated by means of high-pressure x-ray diffraction the structural stability of Pd2Mo3N, Ni2Mo3C0.52N0.48, Co3Mo3C0.62N0.38, and Fe3Mo3C. We have found that they remain stable in their ambient-pressure cubic phase at least up to 48 GPa.
