Li2ZrCl6 with a trigonal structure is low-cost Li+-conducting chloride electrolyte, which stable at high voltages up to 4.2 V and compatible high-voltage cathodes. However, its relatively low room-temperature ionic conductivity, poor stability in different solvents temperatures limit application for next-generation all-solid-state batteries. Herein, we prepared new oxychloride electrolytes mola...

The mixed glass former effect (MGFE) is defined as a nonlinear and nonadditive change in the ionic conductivity with changing glass former fraction at constant modifier composition between two binary glass forming compositions. In this study, mixed glass former (MGF) sodium borophosphate glasses, 0.35Na2O + 0.65[xB2O3 + (1 – x)P2O5], 0 ≤ x ≤ 1, have been prepared, and their sodium ionic conduct...

new two nano- sized schiff base complexes [m(l)], where l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and m=cu or zn, (a, b complexes) were synthesized by ultrasonic irradiation. these complexes were characterized by elemental analysis, molar conductivity, ft-ir, fluorescence emission, 1h nmr, field emission scanning electron sp...

A new unsymmetric thioether diamine N - ( 2 - ( 2 - aminophenylthio) ethyl) benzene - 1 , 2 - diamine was prepared through the nucleophilic substitution of cysteaminium chloride with 1 - chloro - 2 - nitrobenzene and then the nitro groups of prepared compuond converted to the amine by zinc powder and ammonium chloride. Then, unsymmetric Schiff bass ligand 2 - ((( 2 - (( 2 - (( 2 - (( 2 - hydrox...

In recent years, ionic liquids have been used in pharmaceutical processes. Therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. So, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [CnMIm]Br (n = 4, 6 and 8) in various concentrations of aspirin (ASA) ...
