The reaction of methylcarbonate ionic liquids with H2S or H2Se offers a highly selective synthesis of analytically pure, well-defined and soluble hydrosulphide and hydroselenide organic salts of general interest. Among them, imidazolium hydrochalcogenides show an astonishingly high volatility for cation-aprotic ILs, which allows their quantitative sublimation below 100 °C/10(-2) mbar and actual...

We present an ab initio–based kinetic Monte Carlo model for ionic conductivity in single-crystal yttriastabilized zirconia. Ionic interactions are taken into account by combining density functional theory calculations and the cluster expansion method and are found to be essential in reproducing the effective activation energy observed in experiments. The model predicts that the effective energy...

This work studies the kinetics of crystallization charged microgels suspensions Poly-N-Isopropylacrylamide (PNIPAM) at low ionic strength. The liquid-crystal transition is induced by suddenly decreasing temperature microgel dispersion, and process monitored measuring temporal evolution static structure factor dispersion using light scattering. We find that crystal growth rate, indicated crystal...

Bis(2-hydroxyethyl) ammonium stearate (DES) protic ionic liquid crystal (PILC) has been added in 1 wt% and 2 proportion to di-bis(2-hydroxyethyl) succinate (DSU) (PIL) obtain (DSU+1%DES) (DSU+2%DES) lubricant blends. The new blends are non-Newtonian fluids with crystalline domains. Addition of PILC PIL reduces running-in friction coefficient more than 70% prevents surface damage, decreasing wea...
