An effective way to examine structural rearrangement in solids is Mössbauer spectroscopy. A key requirement probes used for these purposes the possibility of their localization a certain site crystal lattice or network amorphous material. When absorption spectroscopy local structure crystalline and Ge2Sb2Te5 films, this satisfied 119Sn isotope. Tin atoms isovalently substitute germanium both vi...

Physics, Moscow, RussiaWe consider cholesteric liquid-crystalline DNA dispersions, and show thatpolymeric (Dau-Cu) complexes, the so-called bridges, between pairs of DNA molecules may generate a super liquid-crystalline structure (BR-phase), charachterized by a soliton lattice of the spatial distribution of theorder parameter. The BR-phase could have a layered spatial structure andan abnormal o...

We demonstrate a new approach for synthesizing Ag-ZnO heterogeneous nanostructures in which single-crystalline ZnO nanorods were selectively grown on {111} rather than {100} facets of single-crystalline Ag truncated nanocubes. We have identified the fine structure of the Ag-ZnO heterostructures and proposed a mechanism indicating that structure match plays a critically important role in this ty...

Crystalline membranes are two-dimensional membranes whose constituent particles form a crystalline mesh. A good example is free standing graphene where carbon atoms form a membrane with a hexagonal lattice structure. What distinguishes crystalline membranes from conventional two-dimensional crystals is the embedding in a three dimensional space which allows for fluctuations not only within the ...
