Solvation sheath是什么
By a IUPAC definition, solvation is an interaction of a solute with the solvent, which leads to stabilization of the solute species in the solution. In the solvated state, an ion or molecule in a solution is surrounded or complexed by solvent molecules. Solvated species can often be described by coordination number, and the complex stability constants. The concept of the solvation interaction can also be applied to an insoluble material, for example, solvation of functi… WebJan 1, 2024 · Conclusions + solvation sheath inside ZIF-71 is calculated to be 0.54 (the lowest value achieved among carbonate electrolytes), indicates almost completely de …
