Systematic studies on the vapor-liquid equilibria (VLE) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([C12mim]Br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

Here, we present a new aqueous biphasic system (ABS) with near neutral pH and containing highly soluble organic/organometallic active species that avoids crossover due to the thermodynamic separation of species. This ABS become best example “Static” Membrane-Free Battery highest maximum theoretical energy density (21.7 Wh L−1), enhanced coulombic efficiency (96%) stable performance over 250 cyc...

A new database was developed to successfully model the solid and aqueous phase equilibria in a number of hydrometallurgical processes using the Mixed Solvent Electrolyte (MSE) model of the OLI Systems software. In order to validate the predictability of the model developed, a number of experimental measurements were conducted in multicomponent solutions containing NiSO4, H2SO4, MnSO4, HCl, etc....

Surface charge governs nanoscale aqueous electrolyte transport, both in engineered analytical systems and in biological entities such as ion channels and ion pumps as a function of ion type and concentration. Embedded electrodes in a nanofluidic channel, isolated from the fluid in the channel by a dielectric layer, act as active, tunable gates to systematically modify local surface charge densi...

The mechanistic aspects of the electrochemical reduction of U(V1) nitrate at a mercury electrode in chloroform, using three different supporting electrolytes, are described. In the presence of tetrabutylarnmonium perchlorate (TBAP) as a neutral electrolyte, UO (NO ) , reduced in two irreversible electrochemical steps to form a U(V1)-U(V) binuclear complex and U(IV), respectively. In the pr...

Two-phase liquid system IA(w)|IX(o) comprising the interface between the aqueous solution (w) of uni-univalent electrolyte IA and an organic solvent solution (o) of a uni-univalent electrolyte IX with the common cation I(+) is considered as a simple model of a liquid-membrane ion-selective electrode (ISE). Taking into account the electroneutrality and mass balance conditions, the equilibrium Ga...

Surface-bound layers of poly(L-glutamic acid) prepared by a recently described "grafting-from" method were analyzed with respect to electrical charging and structural alterations upon variation of pH and concentration of the background electrolyte in aqueous solutions. The microslit electrokinetic setup (MES) was utilized for the combined determination of zeta potential and surface conductivity...

The hydration structure of NaCl aqueous solution was elucidated in carbon nanotubes (CNTs) on the basis of canonical ensemble Monte Carlo simulations. Hydration shells were preferentially formed even in narrow CNTs to gain stabilization energy, whereas hydrogen bonding between water molecules in such CNTs was sacrificed. Nanoscale-confined aqueous electrolyte solutions therefore prioritize hydr...

Abstract In the present investigation, we report incorporation of phosphorous (P) atoms in activated carbon and study its effect on electrochemical performance. Porous is synthesized by chemical activation method from a bioresource then pretreated with nitric acid. Phosphorus were doped simple method. The obtained phosphorous-doped nano-materials show an appreciable change porosity creation mor...
