Abstract Na-ion batteries offer a way to develop large-scale energy storage necessary for the increased adoption of renewable sources. Layered transition metal oxide materials electrodes can be synthesised using abundant and non-toxic materials, decreasing costs risks compared lithium-ion batteries. Solid state processing is commonly used synthesis, long calcinations at high temperatures (>8...

pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as ba, zr sources and stearic acid ascomplexing reagent. the gel was calcined at 800 and 900 °c in air. results of thermal analysisare given, including both dtg and tg. fourier transform infrared spectrometry (ftir), x-raydiffraction (xrd), transmissio...

Titanium oxide nanoparticles were synthesized via a solvothermal treatment of titanium isopropoxide in the presence of L-lysine (lysine). The prepared nanostructures characterized by atomic force microscopy (AFM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), diffraction scanning calorimetry (DSC), scanning electronic microscopy (SEM), transmission electron microscopy (TEM) and...

In this study low-grade magnesium oxide (MgO) produced by calcinations of natural magnesite was used in mine water treatment using a laboratory-column device. The from the abandoned Osor (NE Spain) with MgO showed removal metals both and tailing leachates. PHREEQC numerical code Geochemist’s Workbench (GWB) were to evaluate speciation dissolved constituents calculate saturation state effluents....

This study explores the influence of partial replacement high reactivity Attapulgite (HRA) with cement by weight and evaluate effect curing temperatures on compressive strength modified paste (MCP). Recently, Iraqi clay(Attapulgite) has been processed to pozzolanic material HRA, after extracting it from quarry clays crushed grind filler then specific suitable calcinations temperature make this ...

New binary catalytic systems based on sulphated zirconia-alumina were synthesized by controlled hydrolysis of alkoxides using relative molar ratios constituents 1:1, 1:2 and 1:3 in favour zirconia. The obtained differences the final material?s properties may be related to organic precursor memory effect, applied calcinations temperatures used alumina contents. addition zirconia affected structu...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

Waste water expulsion containing toxic and hazardous ingredients from textile industry is one of the biggest concerns in this modern age. N-doped nano composites as an efficient catalyst are playing a significant role reducing toxicity that effluent. Ti-Mel capped Ag2S NCs (N-Ti-C/Ag2S NCs) TiO2 (TiO2/Ag2S were synthesized via calcinations at 700°C, whereas was prepared by simple hydrothermal t...
