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:

Systematic Variations of Ion Hydration in Aqueous Alkali Metal Fluoride Solutions.
TL;DR: Aqueous solutions of three alkali metal fluorides: NaF, KF and CsF have been studied by dielectric relaxation spectroscopy over the frequency range 0.2 ≤ ν / GHz ≤ 89 at 25 °C and at concentrations 0.05 ≤ c / mol L-1 ≤ 1.

The electrokinetic potential of therapeutic proteins and its modulation: Impact on protein stability
TL;DR: The electrokinetic potential of therapeutic proteins is investigated and how and to what extent the electrokinetically potential can be influenced by variations of solution conditions (e.g. pH, salts and buffer components, amino acids, carbohydrates or detergents).

TL;DR: It is proposed that the size and charge density of the naked ions do not sufficiently account for the differences in the SAXS curves, and for cations, the ion-ion contribution gives a prominent first-order diffraction peak, whereas for anions, the low-Q enhancement in the SAFE curves indicates density inhomogeneities as a result of ion-water interactions.

The Hofmeister effect and the behaviour of water at interfaces.
TL;DR: The first general, detailed qualitative molecular mechanism for the origins of ion-specific (Hofmeister) effects on the surface potential difference at an air-water interface is proposed; this mechanism suggests a simple model for the behaviour of water at all interfaces, regardless of whether the non-aqueous component is neutral or charged, polar or non-polar.

Specific ion effects at the air/water interface.
TL;DR: Aqueous ion-containing interfaces are ubiquitous and play a key role in a plethora of physical, chemical, atmospheric, and biological processes, from which just a few illustrative examples are mentioned.
