Аннотация: Readily available 5-aryl-2,2?-bipyridines and their derivatives are a unique family of fine-tunable chromophores, where changes in the substitution patterns, solvation and coordination are translated into dramatic spectral changes. They exhibit sensitive and selective response to zinc ions with dramatic increases in emission intensity or significant red-shifts of emission maxima????

Аннотация: Mesoporous carbon of lamellar morphology was synthesized by the thermal decomposition of zinc glycerolate in an inert atmosphere followed by the removal of zinc oxide from the ZnO/C composite. The obtained material was characterized by scanning electron microscopy, Raman spectroscopy, and low-temperature adsorption of nitrogen. Mesoporous carbon is remarkable for a high adsorption rate of methylene blue dye from aqueous solutions with the maximum adsorption capacity toward the dye equal to 1680 mg g−1.

Аннотация: Protolytic and complexing properties of N-[1,1-bis(hydroxymethyl)ethyl]- and N-[tris-(hydroxymethyl)methyl]-β-alanine were estimated using the potentiometry. Values of the dissociation constants of amino and carboxyl functional groups in molecules of these reagents, as well as the stability constants of their complexes of various compositions with copper(II), cobalt(II), nickel(II), zinc(II), cadmium(II), silver(I), magnesium(II), calcium(II), strontium(II), and barium(II) ions, were calculated. The hydroxyalkylation of β-alanine tunes its properties towards the considered metal ions. Complexes of copper(II) ions with these β-alanine derivatives are the most stable complex compounds among explored herein.

Аннотация: Zinc enolates derived from 1-aryl-2,2-dibromoalkanones react with N-cyclohexyl-2-oxochromene-3-carboxamides to give N-cyclohexyl-1-alkyl-1-aroyl-2-oxo-1a,7b-dihydrocyclopropa[c]chromene-1a-carboxamides mainly as cis isomers with respect to the substituents in positions 1 and 1a. Reactions of the same zinc enolates with N-benzyl-2-oxochromene-3-carboxamide and N-benzyl-6-bromo-2-oxochromene-3-carboxamide lead to formation of 1-aryl-2-benzyl- and 1-aryl-2-benzyl-6-bromo-1-hydroxy-9c-alkyl-1,2,9b,9c-tetrahydro-5-oxa-2-azacyclopenta[2,3]cyclopropa[1,2-a]naphthalene-3,4-diones. The reaction of zinc enolates with N-aryl-2-oxochromene-3-carboxamides in a weakly polar solvent (diethyl ether or ethyl acetate) affords mixtures of cis-N-aryl-1-aroyl-1-alkyl-2-oxo-1a,7b-dihydrocyclopropa[c]chromene-1a-carboxamides and their cyclic isomers, 9c-alkyl-1,2-diaryl-1-hydroxy-1,2,9b,9c-tetrahydro-5-oxa-2-azacyclopenta[2,3]cyclopropa[1,2-a]naphthalene-3,4-diones, the latter prevailing. N-Substituted 1-alkyl-1-aroyl-2-oxo-1a,7b-dihydrocyclopropa[c]chromene-1a-carboxamides in which the aroyl group on C1 and the carboxamide group on C1a are arranged trans are formed by reactions of zinc enolates with the corresponding 2-oxochromene-3-carboxamides in the presence of hexamethylphosphoric triamide

PETROLOGICAL MODEL -- MODELLING -- ORE -- ORE DEPOSITS
Аннотация: The available data on the giant ore deposits of chromium (Kempirsai in the Urals), platinum-group metals (Bushveld in Africa), platinum-bearing copper-nickel ores (Talnakh in the Noril'sk district, northern part of the Siberian Platform), zinc-copper (massive sulfide) ores (Gai, Sibai, and Uchaly) and apatite deposits (Khibiny, the Kola Peninsula) is summarized. The giant sizes of the deposits are caused by extraordinary ore-forming processes directly associated with the highly extensive petrogenetic processes. These processes resulted in the formation of peculiar dunites in the hyperbasite complexes (chromite ores), agpaitic urtites in alkaline associations (apatite deposits), development of low-sulfide horizons and hortonolite dunites in the basite-hyperbasite layered intrusions (platinum-group metal deposits), specific processes of transmagmatic sulfurization of the iron-rich igneous differentiates (Cu-Ni sulfide and massif sulfide ores), and processes of magmatic replacement of hyperbasites that cause the alkaline agpaitic affinity of magmatism. This agpaitic tendency increases the solubility of carbon-bearing fluid components (CO2, CH4, etc.) in magma and leads to the concentration of ore metals, which form chloride-carbonate and hydrocarbon migrating compounds in the transmagmatic fluids. Some mineralogical-petrological prospecting criteria are deduced on the basis of genetic models of giant ore deposits.
