CO oxidation on the (111) face of Ni has been studied over a wide temperature range and reactant ratio in CO+O2 reaction mixtures. A significant nonstationary increase in the reaction rate due to the formation of a two-dimensional surface oxide has been found. Subsequent formation of threedimensional NiO(111) phase sharply decreases the CO oxidation rate.

The activity of barium nitride in the isotope exchange of nitrogen is 2–3 orders of magnitude higher than that of Fe and Ru. In the temperature range from 373 to 673 K the activation energy of exchange is 40 kJ/mol.

Adsorption of O2 over Pt(111), (110) and (100) at 80 K has been studied by thermodesorption mass-spectrometry. The results indicate the formation of chemisorbed molecular oxygen species and the influence of the surface structure of platinum on the low-temperature adsorption of oxygen.

Adsorption heats q and activation energies of the nitrogen exchange on several metal nitrides have been compared. For the systems capable of changing readily their composition upon varying conditions, the isotope exchange is suggested to be the most reliable method of the determination of q.

The products of selective oxidation are shown to be formed via a stepwise mechanism with participation of surface allylic complexes. A successive transformation of -allyl to -allyl and further to acrolein is possible. The products of complete oxidation may be formed through surface carbonate-carboxylate complexes via either a stepwise mechanism involving the catalyst's oxygen, or a concerted mechanism with the participation of molecular oxygen.

A solid solution of vanadium in MoO3 with a solubility limit of about 3 mol.% V2O5 is shown to be formed. Its catalytic properties are discussed.

The Ru(001) plane is shown to possess high but variable activity in the reaction of CO oxidation. A drop of activity is attributed to the transformation of surface oxygen into the unreactive state.

Diffusion and solubility coefficients of O2, SO2 and SO3 in the active component of vanadium catalysts have been determined by a high-speed relaxation method. Processes of their dissolution are shown to be quasi-equilibrium with respect to catalytic reactions.

A new mechanism for the generation of an azimuthal anisotropy of particles produced in heavy-ion collisions is analyzed. An analysis is performed within Reggeon theory and is general. The resulting effect can be interpreted in terms of the partonic structure of a fast nucleus. This mechanismcan contribute significantly to the observed value of the elliptic flow υ 2. The dynamics in question differs significantly from a standard mechanism of the collective motion of a hadron medium after a collision.
