Recent advances in synthetic materials sciences such as the incorporation of self-assembly, sol–gel, and layer-by-layer deposition chemistry have afforded the development of many interesting and potentially useful nanostructures. Among those, nanoarchitectures in which a core nanoparticle, often a transition metal, is encapsulated by an outer layer of a second material, typically a porous oxide...

Methanation is capable of chemical storage fluctuating renewable energy, which requires fundamental understanding the dynamics kinetic processes taking place on catalyst surface. In order to elucidate impact support dynamics, Co-based model catalysts were synthesized via double flame spray pyrolysis (DFSP) differing only in materials. particular, Co nanoparticles identical particle size distrib...

The influence of Al2O3 in the range 10–20 mass% and TiO2 0.55–5 on flow behavior, viscosity, density, surface tension molten industrial blast furnace slag with CaO/SiO2 = 1.13 is investigated using a high-temperature microscope, rotating viscometer, maximum bubble pressure method. measurement results show that acts as network former studied CaO–SiO2–MgO–Al2O3–TiO2 slags. With an increase conten...

we report on the synthesis, morphology, chemically and structurally of tio2-cuo-sio2 nanostructure with different precursors molar ratio and calcined temperatures. in the present work, ternary reactive powders in the tio2-cuo-sio2 systems have been obtained using the sol-gel method, by the simultaneous gelation of all cations. the compounds and other elements change in special chemical and phys...

This study examines the incorporation of TiO2 into sodium borosilicate glasses and its effect on formation glassy crystalline microphases. Glasses in composition range: 7Na2O–23B2O3–(70 - X)SiO2–XTiO2 (where X = 0–14.6 mol.% TiO2) which exhibit phase separation were investigated. Raman studies confirm two different coordinations depending molar content TiO2. Thermal properties are unaffected by...

Dengan penerapan strategi kopresipitasi, sol-gel hidrotermal, bah...

The Pingshuo Mine is an important coal mine of the Ningwu coalfield in northern Shanxi Province, China. To investigate the mineralogy and geochemistry of Pingshuo coals, core samples from the mineable No. 4 coals were collected. The minerals, major element oxides, and trace elements were analyzed by scanning electron microscopy (SEM), LTA-XRD in combination with Siroquant software, X-ray fluore...
