A new method for the hydrogenation of a primary coal tar fraction in the presence of a nanocatalyst at an elevated pressure in an atmosphere of hydrogen was proposed. The effect of the relative H-donor ability of the primary ...

Use of cheap local raw material resources (barite and witherite concentrates of the Karagailinsk deposit, Arkalyk clay, chromite-magnesite scrap objects, copper production dump slag, chromite ore, etc.) makes it possible ...

Equilibrium geometries of the ground electronic state of anthracene dimers are obtained using the density functional level of theory with the B97D hybrid functional and the TZVP basis set and their electronic absorption ...

We establish exact-order estimates for the trigonometric widths of the Nikol’skii–Besov classes of periodic functions of many variables in the Lebesgue space with mixed norm.

Three compounds with the general formula YbM 3 II Fe5O12 (MII = Mg, Ca, Sr) have been prepared for the first time by high-temperature solid-state reactions between ytterbium(III) oxide, iron(III) oxide, and alkaline-earth ...
