The forces between charged macromolecules, usually given in terms of osmotic pressure, are highly affected by the intervening ionic solution. While in most theoretical studies the solution is treated as a homogeneous structureless dielectric medium, recent experimental studies concluded that, for a bathing solution composed of two solvents (binary mixture), the osmotic pressure between charged ...

The thermo-solvatochromism of 2,6-dibromo-4-[(E)-2-(1-methylpyridinium-4-yl)ethenyl] phenolate, MePMBr(2), has been studied in mixtures of water, W, with ionic liquids, ILs, in the temperature range of 10 to 60 degrees C, where feasible. The objectives of the study were to test the applicability of a recently introduced solvation model, and to assess the relative importance of solute-solvent so...

We study the solvation of molecules and ions that are key in context molten carbonate electrolyser cells using first-principles simulations. Focusing on electroreduction CO2 to CO a medium, we investigate both reactant product eutectic LiKCO3 (containing 62% Li2CO3, 38% K2CO3). is found spontaneously react with form transient pyrocarbonate species, C2O52−. To similar reaction could occur CO32− ...
