Group of CEST researches received a patent “Method of synthesis of superhard material and superhard material based on tungsten pentaboride”:
“Diamond is one of the only materials hard and tough enough for the job of constant grinding without significant wear, but diamonds are pricey. High costs drive the search for new hard and superhard materials. However, the experimental trial-and-error search is expensive. A simple, reliable way to predict new material properties is needed to facilitate modern technology development. Using a computational algorithm, Russian theorists have published a predictive tool in the Journal of Applied Physics”.
Also there are several news reports about their studies:
