St-Petersburg State Mining University, V. O., 21 line, 199106 St-Petersburg, Russia
Abstract. The expediency of introducing the concept of “surface — nanostructured metals” was justified. The possibilities of adsorption modification of the surface of metal powders in vapors of quaternary ammonium compounds for regulation of the tribochemical properties of metals and lubricants containing these metals as additives was analyzed. The general trend is that in order to achieve a minimal index of friction D of tribological pair with a lubricant a combination of good
properties of additive is necessary. One is good water-repellent, another is low reactivity of the surface of metallic additives.
Keywords: adsorption modification, metal powders, nanostructured metallic composites, friction, adhesion, lubricant.

Abstract. This paper presents an elementary model of a two-dimensional relativistic scattering of a spin-1/2 fermion
in an axial-symmetric potential in the presence of magnetic field. An exact solution of the two-dimensional Dirac equation
in the continuum is found. An explicit expression for the scattering amplitude is obtained. The last one can be written as
a sum of two terms. One of them is the amplitude of the Aharonov — Bohm effect, and the second corresponds to the
scattered cylindrical wave. In these expressions the dependence on the spin of the incoming particle can be distinguish
explicitly. The numerical simulation of the differential scattering cross section, depending on various system parameters
is performed. On the basis of the results the necessary conditions for the existence of spin effects are formulated.
Keywords: Dirac equation, Aharonov — Bohm effect, spin transport.

Voronezh State University, Universitetskaya pl. 1, 394006 Voronezh, Russia
Abstract. Kinetics of nickel electrodeposition from asparaginate and succinate electrolytes is studied. It is shown,
that irrespective of the ligand nature the process occurs irreversibly under mixed kinetics conditions with dominant control
by charge transfer and is complicated by adsorption. All the complexes present in the baths are electroactive and reduced
simultaneously. Nature of organic acid generally affects the process rate and its kinetic characteristics. Namely, the more
stable complexes are formed, the larger charge transfer coefficient and the less charge transfer rate constant. In succinate
electrolytes hydrogen evolution reaction strongly contributes to the total current.
Keywords: nickel, electrodeposition, kinetics, complexes, asparaginic acid, succinic acid.
