The nanotwinned structures in metals exhibit the unique combination of physical properties. The unifying approach is developed that can be applied to nanocrystalline (nc) materials with different crystal structures. It is used to make a bridge betwee

The deformation twinning of nanocrystalline materials is analyzed within the dislocation theory of twins. This approach is used for the description of the recently observed inverse grain size effect in nanocrystalline face-centered-cubic metals. The

A novel type of photonic crystal formed by embedding a periodic array of constituent stacks of alternating graphene and dielectric discs into a background dielectric medium is proposed. The photonic band structure and transmittance of such photonic c

The possibility of the formation of stripes in the high-temperature superconductor Y Ba 2 Cu 3 O 7 − δ (YBCO) due to interaction between the charged oxygen vacancies or di-vacancies is shown. The high-angle grain boundaries (GBs) regions are prefe

We study the meson exchange currents (MEC) mechanism for the pion double-charge exchange (DCX) reaction in a composite-meson model. The model assumes that the mesons are two-quark systems and can interact with each other only through quark loops. The

The results of a computer simulation of the atomic structure of interfaces in YBa2Cu3O7−δ (twin boundary and large-angle symmetrical tilt grain boundary) are presented. These results allow us to determine the lattice displacements and distortions

Surfaces of natural diamonds etched in high-pressure experiments in H2O, CO2 and H2O-NaCl fluids were investigated using Atomic Force Microscopy. Partial dissolution of the crystals produced several types of surface features including the well-known
