The article deals with tribochemical influence of the surface activity of biosynthetic oils on the operational efficiency and reliability of lubricated friction nodes under the critical conditions. It is proved that the ...

The article deals with the scientific work of a famous Ukrainian historian and source scholar Volodymyr Hrabovetskyі. In the creative heritage of the scientist there is a series of works dedicated to the history of Gali...

A quantum chemical analysis has been carried out of the equilibrium structure and energy parameters of hydrated Li+, Na+, and K+ cations interacting with ionized silica surface by means of density functional theory metho...

A technology for direct laser writing of code sequences on modulation disks has been developed and implemented, ensuring high accuracy and reliability in the process of forming structural elements. The main advantages of...

An algorithm for analyzing double-crystal rocking curves from the near-surface layers of monocrystals has been proposed, and corresponding software has been developed. It is taken into account that to obtain correct resu...

Nanosized CuFe2O4 ferrite was synthesized through the sol-gel self-combustion technique, using iron and copper nitrates with citric acid as fuel. The synthesized ferrite was subsequently analyzed using X-ray diffraction ...

The problem of stochastic averaging of the decayed dynamics of the output state population of a one-step transformation process with constant deterministic forward transition rate and randomly varying return transition r...

Photocatalytic oxidation of organic contaminants is a hot topic in environmental research. However, an effective purification process needs an effective photoreactor. Typical light sources such as mercury and halogen lam...

The article substantiates the fact that several approaches should be considered when building an organizational and economic mechanism for the development of woodworking enterprises, in particular: process-based, innovat...

The method of calculation of diffusion flows under phase transformations in alloys are iron - carbon - alloying element using the principles of nonequilibrium thermodynamics. The expressions for calculation of cross-fact...

The problem of heat and mass transfer of a porous catalyst particle is considered. On the her surface, including the inner surface of the pores, an irreversibly heterogeneous first-order reaction proceeds. It has been an...

We present DC conductivity measurements of newly synthesised and thermally annealed (As2S3)1-x (Bi2S3)x (0.08 ≤ x ≤ 0.14) glasses. X-ray diffraction measurements show that as-prepared As2S3)1-x(Bi2S3)x glasses we...

In the equiatomic approximation, the dependence of the lattice FCC parameter and the Debye temperature from the atomic fate x of the doping element, which is alternately represented by all elements of a multicomponent so...
