An analysis of theoretical studies on the electronic structures and chemical properties of superheavy elements has been performed. It is noted that the specific features of calculations of molecular systems including superheavy element atoms are determined by the exceptional role of relativistic effects that should be taken into account at all stages of electronic structure modelling. The main approximations for relativistic Hamiltonians and general approaches to the solution of the many-electron problem for both superheavy element atoms and their compounds have been considered and compared. The results of modelling the chemical properties of superheavy elements by ab initio methods and density functional theory have been analysed.

The state of the art of studies dealing with development and perfection of methods for metal protection against corrosion by azole heterocycles is considered. The composition and the key mechanisms of formation of ultrathin (nanosized) protective layers on the surface of various metals by these inhibitors are discussed.

Conventional and novel syntheses of silver nanoparticles are considered, their advantages and shortcomings are analysed. Attention is focused on the shape-controlled methods of preparation of nanosized particles. The unique optical and antibacterial properties of nanosilver and related applications are discussed.

Data on the synthesis and physicochemical studies of salts of mono- or dibasic unsaturated carboxylic acids and unsaturated metal oxo-carboxylates are generalised and described systematically. The structures and properties of the COO group in various compounds and characteristic features of the structures of carboxylate complexes are analysed. The main routes and kinetics of polymerisation transformations of unsaturated metal carboxylates are considered. The attention is focused on the effect of the metal ion on the monomer reactivity and the polymer morphology and structure. The possibility of stereochemical control of radical polymerisation of unsaturated metal carboxylates is demonstrated. The electronic, magnetic, optical, absorption and thermal properties of metal (co)polymers and nanocomposites and their main applications are considered.
