Ions in water: characterizing the forces that control chemical processes and biological structure.
TLDR
Two different techniques indicate that the interaction of water with anions is by an approximately linear hydrogen bond, suggesting that the dominant forces on ions in water are short range forces of a chemical nature.About:

Selectivity of ion exchange membranes: A review
TL;DR: It is concluded that synthetic methods have evolved rapidly and development of fundamental knowledge on the many complex phenomena occurring in the adaptive membrane bulk and solution-interface environments is not sufficiently established, and much effort is required to combine experimental, theoretical, and simulation data for a more comprehensive and coherent understanding of these phenomena.
Journal ArticleDOI
Cooperativity in Ion Hydration
TL;DR: A combined terahertz and femtosecond infrared spectroscopic study of water dynamics around different ions reveals that the effect of ions and counterions on water can be strongly interdependent and nonadditive, and in certain cases extends well beyond the first solvation shell of water molecules directly surrounding the ion.

TL;DR: A mechanism for specific ion effects is elucidated for aqueous systems containing charged and uncharged polymers, polypeptides, and proteins and a hydrogen-bonding mechanism is tested for the urea denaturation of proteins with some of these same systems.

Low-barrier hydrogen bonds and enzymatic catalysis.
TL;DR: It is likely that low-barrier hydrogen bonds form at the transition state of any reaction involving general-acid or general-base catalysis, as at that point the pKs of the catalytic group and reactant will be equal.

Coordination of Water to Magnesium Cations
TL;DR: In this paper, the stereochemistry of binding of ligands by divalent metals and the propensity of these ligands to be water were investigated with respect to the coordination of water molecules and other groups around a magnesium ion and any possible variability in the coordination number of magnesium.

Hydration structure and free energy of biomolecularly specific aqueous dications, including Zn2+ and first transition row metals.
TL;DR: The hydration of some of the alkaline earth divalent metal cations and first row transitionMetal cations is considered within the quasi-chemical theory of solutions and it is seen that the ligand field contributions play an important role in the physics of hydration.
