Various Hopf fibrations of polytope 240 are obtained. Six rod structures consisting of tetrahedral atoms are derived by rolling a polytope 240 along three-dimensional Euclidean space E3 and simultaneous mapping to this space. The axes of these rod st

Various intersections of Boerdijk–Coxeter (BC) helices consisting of regular tetrahedra and having the same chirality are considered in a three-dimensional Euclidean space. The angles between their axes are calculated. Next, these rigorous geometri

The main types of structures consisting of adjacent and/or intersecting helices 30/11 formed by tetrahedrally coordinated atoms have been investigated. These structures are fundamentally noncrystalline. Nevertheless, they can take form of regularly f

The epitaxial mechanism of diamond crystal nucleation by the (110) face on the Mo(110) face during chemical vapor deposition on a molybdenum plate has been established. It is shown that, under the synthesis conditions in use, only cubic sectors of di

A composite material (CM) reinforced by diamond particles is fabricated from a mixture of cobalt and 10 wt % C60 powders at a pressure of 8 GPa and a temperature of 1200–1300°C, which is close to the melting temperature of the metastable Co–C eu

Cluster–rod structure were designed, which are comprised of tetrahedral atoms with a typical torsion angle of ~38° at interatomic bonds. These structures correspond to a muscle tissue and clathrin lattice by their metrics and topology and can be f

Structural mechanisms are proposed for experimentally observed phase transitions between crystalline modifications of aqueous ice, Ih and II, as well as II and Ic. It is known that the Ih–II transition occurs with the conservation of large structur
