TL;DR: The PRIRODA program suite as discussed by the authors is designed for the study of complex molecular systems by density functional theory, at the MP2, MP3, and MP4 levels of multiparticle perturbation theory, and by the coupled-cluster single and double excitations method (CCSD) with the application of parallel computing.
Abstract: Main characteristics are described of the PRIRODA quantum-chemical program suite designed for the study of complex molecular systems by the density functional theory, at the MP2, MP3, and MP4 levels of multiparticle perturbation theory, and by the coupled-cluster single and double excitations method (CCSD) with the application of parallel computing. A number of examples of calculations are presented.

TL;DR: In the case of weakly expressed electrostatic interactions, the adsorption on zeolites is closest in nature to adsorptions on microporous adsorbents, which do not contain active centers in the form of cations.
Abstract: 1.
Synthetic zeolites of various compositions and crystal chemical structures differ extremely substantially in average density in the adsorption space of the cations accessible for direct interaction with the molecules being adsorbed, and in their number for a unit mass of the adsorbent. This determines the limiting cases of adsorption with a weakly or strongly expressed role of the electrostatic component in the total adsorption interaction.
2.
The volume nature of the filling of the micropores of the zeolite and, in a satisfactory approximation, the temperature invariance of the characteristic equation of adsorption, are the experimental bases for the theory of the adsorption of gases and vapors on zeolites.
3.
In the case of weakly expressed electrostatic interactions, the adsorption on zeolites is closest in nature to adsorption on microporous adsorbents, which do not contain active centers in the form of cations in the adsorption space.

TL;DR: In this paper, the properties of responsible for biological activity tetrazoles are considered and examples are given of active pharmaceutical ingredients of modern drugs containing the tetrazole ring in the molecular structure.
Abstract: Properties of responsible for biological activity tetrazoles are considered. Examples are given of active pharmaceutical ingredients of modern drugs containing the tetrazole ring in the molecular structure.

TL;DR: In this paper, a review of nitrogen fixation in solution is presented, where the optimum catalyst is the polynuclear complex, and the limiting step involves the electron transfer from a reducing agent.
Abstract: Reports on nitrogen fixation in solution are reviewed. The optimum catalyst is the polynuclear complex. The reaction proceeds as a multielectron process, and the limiting step involves the electron transfer from a reducing agent.

TL;DR: In this paper, side self-oxidation of thiols was studied and it was found that these reactions in neutral and alkaline solutions are induced by impurities of variable-valence metals.
Abstract: Side self-oxidation of thiols was studied. It was found that these reactions in neutral and alkaline solutions are induced by impurities of variable-valence metals. The ability of transition metals to catalyze oxidation of thiols changes in the order Cu > Mn > Fe > Ni ≫ Co. The plot of the self-oxidation rate vs. pH passes through a maximum whose position on the pH scale depends on both the nature of metal and the structure of the thiol oxidized. For thiols having different structures, the kinetic orders in reactions catalyzed by copper ions differently vary with pH, which is apparently associated with the formation of complexes possessing different catalytic activity.
