A nonlinear and nonadditive composition-dependent change of the ionic conductivity in mixed glass-former (MGF) glasses when one glass former, such as PS(5/2), is replaced by a second glass former, such as GeS2, at constant alkali modifier concentrations, such as Na2S, is known as the mixed glass-former effect (MGFE). Alkali ion conducting glasses are of particular interest for use as solid elec...

Densities ρ and Viscosities ŋ of D-Galactose D-Maltose (0.05-0.4)M in aqueous solution (0.25) M Na2S at 298.15, 303.15 308.15K have been measured. From these experimental data, apparent molal Volume Limiting Apparent Molal ( ) ,The slope , Jones-Dole coefficient A B, The free energy activation viscous flow (ΔG*), enthalpies (ΔH*) Entropies (ΔS*) were calculated, values compatible with the weak ...

Electrocatalysis-assisted entrapment of polysulfide while ensuring efficient nucleation Na2S holds the key to addressing shuttle effect and sluggish kinetics in room-temperature (RT) Na/S batteries. The constrained active sites, however, dramatically limit efficiency electrocatalysts. Here, a strategy electrochemically releasing nano-silver catalytic sites during discharge process is presented,...

One-pot deoxygenation of kraft lignin to aromatics and hydrocarbons fuel-range quality is a promising way improve its added value. Since most the commercially resourced lignins are impure (Na, S, K, Ca, etc., present as impurities), effect these impurities on activity catalyst critical was scrutinized in this study using NiMoS/Al2O3 catalyst. The removal from indicated that they obstructed depo...

Porphyry-type deposits are the major sources of copper and molybdenum, flotation has been adopted to recover them separately. The conventional reagents used for depressing minerals, such as NaHS, Na2S, Nokes reagent, have potential emit toxic H2S gas when pulp pH was not properly controlled. Thus, in this study applicability microencapsulation (ME) using ferrous phosphate ions an alternative pr...

This work describes the optical and structure properties of nickel sulfide and cobalt sulfide nanoparticles in ZSM-5 zeolite. The samples were obtained by sulfidation of the Ni2+ and Co2+ ion-exchange ZSM-5 zeolites in a Na2S solution at room temperature. The optical properties of the samples were studied by UV-visible spectroscopy. Their crystalline structure and morphology were studied by X-r...

Solid solutions of CdS and CdSe of different compositions were prepared by s inter ing pressed pellets and vacuum evaporation. The bandgap of the mixtures varied monotonical ly with percent composition be tween that of CdS and CdSe. Studies of the photoassisted oxidation of sulfide with these electrodes wi th a 1M Na2S, 0.1M NaOH electrolyte showed that the flatband potentials (Vfb) of the mixt...
