Recent studies have shown that hardness, a complex property, can be calculated using very simple approaches or even analytical formulae. These form the basis for evaluating controversial experimental results (as we illustrate for TiO2-cotunnite) and enable a systematic search for novel hard materials, for instance, using global optimization algorithms (as we show on the example of SiO2 polymorphs). 
Search for superhard carbon: between graphite and diamond
A brief review has been presented of the recent studies aimed at searching for new 3D (sp3) carbon allotropes of increased hardness and carried out using computational approaches. The principles ofExpand

Thanks to recent progress, it has become possible to reasonably accurately compute the hardness of materials theoretically, from crystal structures. The existing models have, however, some weaknessesExpand
First-principles structural design of superhard materials.
This work adopted hardness as the fitness function in combination with the first-principles calculation to construct the hardness vs. energy map by seeking a proper balance between hardness and energy for a better mechanical description of given chemical systems. Expand

First-principle calculations on the structural stability and electronic properties of superhard BxCy compounds.
It is found that the hardness of the B-C system has a decreasing trend with the increase of boron concentration, and the bonds with high electron density and short bond length have an important contribution to the hardness in the BxCy system. Expand
Synthesis of nanocrystalline bulk SiO2 stishovite with very high toughness
Nanocrystalline bulk stishovite, with pure SiO 2 composition, was synthesized under high pressure and temperature. We found that this material has an extremely high fracture toughness (∼13 MPa m 1/2Expand
