We have determined the electron stopping power (SP) and inelastic mean free path (IMFP) of (ZrO2)x(SiO2)1-x (x=1, 0.75, 0.5, 0.25, 0) for electron energies from 100 eV to 30 keV by means of modified Born–Ochkur equations. The energy loss function (ELF) is... see more

Researches about the effects of aging time toward crystallinity of products in the synthesis of mesoporous silicates MCM-41 have been done. MCM-41 was synthesized by hydrothermal treatment to the mixture of sodium silicate, sodium hydroxide, cetyltrimetyl... see more

The dissolution rate of silicate minerals and glasses in alkaline environments is of importance in cementitious systems due to its influences on: (a) early-age reactivity that affects the rate of strength gain and microstructure formation, and/or, (b) che... see more

A universal calculation model for theoretical description of structural and  physicochemical properties of aqueous solutions of modified silicates with the involvement of complexing agents is offered. The model takes into consideration three types of... see more

Mining and Mineral Engineering has a powerful impact on the environment. In the areas of mining taking place radical changes of geological environment that are irreversible. Groundwater, as part of the four component hydrogeological system undergo signifi... see more

Mesoporous tungsten-silicates, W-MMM-E, have been prepared following evaporation-induced self-assembly methodology and characterized by elemental analysis, XRD, N2 adsorption, STEM-HAADF (high angle annular dark field in scanning-TEM mode), DRS UV-vis, an... see more

Cesium chemisorption phenomenon strongly contributes to the source terms transport during light water nuclear reactor accidents. Large amounts of cesium silicates are identified to be chemisorbed onto structure material, reduce cesium volatility, and affe... see more

Nanoparticles of silicates and germanates with a general formula Sr2R8–x–yErxYbyM6O26 (R = Y, La; M = Si, Ge) were produced in vacuum by the method of pulse electron beam evaporation. An upconversion photoluminescence of the nanoparticles was detected dur... see more

The phase formation of the solid solution Ca5Mg4–xZnx(VO4)6 (0=x=4) was studied in situ using differential scanning calorimetry and high-temperature X-Ray powder diffraction (XRPD). XRPD analysis shows the appearance of unavoidable secondary pyrovanadate ... see more
