  • Boron: a hunt for superhard polymorphs 
    Oganov, A.R.; Solozhenko, V.L. (Сверхтвердые материалы, 2009)
    Boron is a unique element, being the only element, all known polymorphs1 of which are superhard, and all of its crystal structures are distinct from any other element. The electron-deficient bonding in boron explains its ...
  • Metastable host–guest structure of carbon 
    Zhu, Q.; Feya, O.D.; Boulfelfel, S.E.; Oganov, A.R. (Сверхтвердые материалы, 2014)
    A family of metastable host–guest structures, the prototype of which is a tetragonal tP9 structure with 9 atoms per cell has been found. It is composed of an 8-atoms tetragonal host, with atoms filling channels oriented ...
  • Novel sp³ forms of carbon predicted by evolutionary metadynamics and analysis of their synthesizability using transition path sampling 
    Boulfelfel, S.E.; Zhu, Q.; Oganov, A.R. (Сверхтвердые материалы, 2012)
    Experiments on cold compression of graphite have indicated the existence of a new superhard and transparent allotrope of carbon. Numerous metastable candidate structures featuring different topologies have been proposed ...
  • Towards the theory of hardness of materials 
    Oganov, A.R.; Lyakhov, A.O. (Сверхтвердые материалы, 2010)
    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 ...
