The catalytic process for methanol production by synthesis gas conversion under the conditions of mechanochemical activation (MCA) of copper-zinc-aluminum oxide catalyst in the temperature range 160–280 °C at a pressure of 0.1 MPa are investigated. The us... see more

The catalytic process for methanol production by synthesis gas conversion under the conditions of mechanochemical activation (MCA) of copper-zinc-aluminum oxide catalyst in the temperature range 160–280 °C at a pressure of 0.1 MPa are investigated. The us... see more

This article presents the results of the mechanochemical activation of coal in a shock-grinding-type mill and the ?-radiation effect of a stream of electrons at the LU-6 electron accelerator. It was established that during the hydrogenation of dispersed c... see more

With aim of usage of glauconites as a K-fertilizers and microfertilizers the sorption properties of modified glauconite with respect to ions  of Zn, Mn, Ni, Cu, Co (II), containing in  insufficient quantity in  most soils of  Republic ... see more

The interaction of a solid inert metal Ru with liquid active metal Ga during mechanical activation in a high-energy planetary ball mill was studied using the X-ray diffraction and the high resolution scanning electron microscopy with energy dispersive X-r... see more

Synthesis by mechanochemical activation route and optimisation for power harvesting properties of nano-structured Pb0.98La0.02(NiSb)0.05[(Zr0.52Ti0.48)0.995]0.95O3 [La-PNS-PZT] ferroelectric ceramic composition has been carried out and reported here for t... see more

The orthophosphates LiFe0.9M0.1PO4 with the structure of olivine doped with vanadium and titanium were obtained by mechanochemically stimulated solidphase synthesis using high-energy planetary mill AGO-2 and subsequent annealing at 750 °C. It is shown tha... see more

In this study, the syntheses of cementite (Fe3C) and pyrite (FeS2) have been performed by mechanical activation of a mixture of graphite or sulfur with amorphous or crystalline silica in a planetary ball mill AGO-2 with steel fittings. XRD analysis was us... see more

In this work, we obtained polycalciumphenylsiloxane (PCPS) by the interaction of calcium bis (acetylacetonate) with polyphenylsiloxane. The first method consisted in boiling the starting reagents in toluene for several hours; the second was as follows: th... see more
