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.

TL;DR: The lengths of short strong hydrogen bonds (SSHBs) on enzymes have been determined with high precision (±005 A) from the chemical shifts (δ), and independently from the D/H fractionation factors (φ) of the highly deshielded protons involved as discussed by the authors.

TL;DR: In this article, the authors examined the possible structures of hydrated Be[sup 2+] ions with up to six water molecules partitioned between the first and second coordination shells, and found that the lowest energy configuration has four water molecules in the first shell with any remaining water molecules relegated to the second shell.

Dominant role of local dipolar interactions in phosphate binding to a receptor cleft with an electronegative charge surface: equilibrium, kinetic, and crystallographic studies.
TL;DR: The results indicate that the high specificity, affinity, and rate of phosphate binding are not influenced by the noncomplementary electronegative surface potential of the cleft.

Anion hopping of (and on) functional oligoarginines: from chloroform to cells
TL;DR: A unified view of this "demystified arginine magic" is proposed, focusing on the manipulation of the underlying anion hopping of and on these sticky molecular chameleons according to the principle of Le Chatelier.
