Electrochemical water splitting technology has attracted researchers for the development of next generation fuels. Herein, we report the synthesis of nanostructured porous hollow nickel telluride nanosheets and their use as bifunctional electrocatalyst towards hydrogen and oxygen evolution react...

Smart stannate based coatings were used for improving the corrosion resistance of AZ91D alloy. The proposed coatings characterize with their safety compared with the process involving toxic chromate. They are also industrially applicable and economically attractive where only two steps are neede...

A superhydrophobic stannate coating with self-healing functionality was fabricated on surface of AZ91D magnesium. The hierarchical micro-nano structure was created through two steps, an acid corrosive process and deposition of stannate. The coating was modified with stearic acid after 4 h self-h...

The characteristics of the formation of conversion coatings on an AZ91D Mg alloy were detailed. Because the galvanic effect prevailed around the eutectic α + β, alkaline stannate conversion coatings nucleated first near the β phase where plenty Mg2+ were present. Conversely, the formation of ...

The experimental results of the thermal conductivities of xonotlite-type calcium silicate insulation materials were presented at different temperatures and pressures. Two appropriative surroundings, i.e. an elevated temperature surrounding from ambient temperature to 1450 K and a vacuum surround...

Natural organic polyelectrolytes (humic and fulvic acids) and their metal complexes were removed by adsorption onto xonotlite. The removal percentages of humic and fulvic acids by xonotlite were ≈80% and 30%, respectively. Humic acid removal from solution by adsorption onto xonotlite took place...

The uptake of Nd(III) by the crystalline C–S–H phases 11 Å tobermorite and xonotlite has been investigated by the combined use of wet chemistry techniques, extended X-ray absorption fine structure (EXAFS) spectroscopy, and X-ray diffraction (XRD) in combination with Rietveld refinement. The re...

We use a combined experimental/theoretical approach to investigate the structure and stability of the silicate tetrahedral double chain in xonotlite. The M2a2bc polytype of xonotlite was found to be dominant in the synthetic samples. This polytype was used to predict the relative stability of si...

Ruthenium(0) nanoparticles supported on xonotlite nanowire (Ru(0)/X-NW) were prepared by the ion exchange of Ru3+ ions with Ca2+ ions in the lattice of xonotlite nanowire followed by their reduction with sodium borohydride in aqueous solution at room temperature. Ru(0)/X-NW show high catalytic a...

Xonotlite was synthesized and tested for phosphate removal and recovery from synthetic solution in a batch mode. The effects of pH, initial calcium concentration, bicarbonate concentration on phosphate removal through crystallization were examined. The morphology and X-ray diffraction (XRD) patt...

Xonotlite fibers have attracted much attention in super thermal insulation and flame retardant fields due to its ultra-light property. In this article, well crystalline xonotlite fibers were successfully prepared from two kinds of industry wastes, carbide slag and acid residues of fly ash respec...

Carbide slag modified using ultrasonic technology is used as the calcareous materials for the first time to prepare xonotlite via dynamic hydrothermal synthesis. This paper analyzes the effect of modification conditions on carbide slag activity, crystalline phase composition and morphology of xo...

Carbide slag was used as the calcareous materials for the first time to prepare xonotlite via dynamic hydrothermal synthesis. The effects of influential factors including different calcination temperatures, pretreatment methods of the carbide slag and process parameters of hydrothermal synthesis...

In this research novel microcomposites composed of phase change materials (PCMs) and xonotlite were fabricated and characterized. Xonotlite mineral and its composites have wide application areas in building materials industry due to their thermo-insulating properties. Lauric acid, decanoic acid ...

Densities, sound velocities and viscosities of aqueous sodium metatungstate (SMT) solutions, medium for heavy mineral separations, have been measured accurately in a concentration range from 0.0055 mol kg− 1 to 1.73 mol kg− 1 at 288.15, 293.15, 298.15, 303.15 and 308.15 K at 1 atm. The data were...

We report a scalable two-step plasma mediated process for the synthesis of sillimanite and mullite spray grade powders and their coatings on stainless steel (SS) substrate. In the first step, spray grade sillimanite and mullite powders were prepared by thermal plasma processing followed by secon...

Direct Inlet Mass Spectrometry (DIMS) is used for studying mixtures of PVC with thermal stabilizers. The stabilizers used, Ba/Cd stearates and dibasic lead phosphite, have different ways of action that are followed successfully by DIMS. The method is used particularly to compare the effectivenes...

The properties of several different versions of near equi-molar proportioned lead-zirconate-titanate ceramic piezoelectric plates were measured after irradiation for up to 48 h in an MTR hollow fuel element. The irradiation temperature was 180 ± 50°C and the maximum fluences 3.5 × 1019 therma...

Irradiation experiments have been performed for cadmium niobate (Cd2Nb2O7) pyrochlore single crystals at both 150 and 300 K using 1.0 MeV Au2+ ions over fluences ranging from 0.01 to 0.10 ions/nm2. In-situ 3.0 MeV He+ Rutherford backscattering spectrometry along the 〈100〉-axial channeling dire...

Ferroelectric lead titanate zirconate ceramics prepared by sintering in air are found to have p-type conductivity, believed to result from an excess of lead vacancies. Donor substituants for lead, titanium, or zirconium reduce the conductivity by electron-hole compensation, but n-type conductivi...
