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:

Ion disturbance and clustering in the NaCl water solutions
TL;DR: Ion pairing and ion induction to solvent play an important role in the protein folding and chemical reactions in the water solutions and the clustering level of ions is sensitive to the force field used in the simulations.

Ion-macromolecule interactions studied with model polyurethanes
Borja Fernández d’Arlas,Borja Fernández d’Arlas,Miguel A. Huertos,Miguel A. Huertos,Alejandro J. Müller,Alejandro J. Müller +5 more
TL;DR: A model polyurethane catiomer (PU+) with high density of hydrogen donors and acceptors has been designed and synthesized in order to study ion-macromolecule interactions by means of dynamic light scattering, infrared spectroscopy and nuclear magnetic resonance.

Counterion-specific clouding in aqueous anionic surfactant: a case of Hofmeister-like series
Sanjay Kumar Yadav,Sanjeev Kumar +1 more
TL;DR: Two ionic surfactants (sodium dodecylsulphate (SDS) and sodium dodecylonbenzenesuphonate (SDBS)) are chosen, and effect of addition of quaternary bromide or chloride (tetra-n-butylammonium bromides, tetra-butylphosphonium Bromide, tetraphenylphophosphonion Bromides and benzyl tributylammium chloride) has been studied on the cloud point (CP) behaviour in aque

Structure and solvation thermodynamics of asymmetric poly (acrylic acid)-b-polystyrene polyelectrolyte block copolymer micelle in water: Effect of charge density and chemical composition
TL;DR: In this article, the authors studied the thermodynamic behavior of micelles formed by polystyrene-b-poly(acrylic acid) copolymer chains in salt-free aqueous solution.

Ion-specific weak adsorption of salts and water/octanol transfer free energy of a model amphiphilic hexapeptide.
TL;DR: Both energies of solvation as well as transfer into octanol strongly depend on the nature of the electrolytes used to formulate any buffer, which could be used on separation processes based on criteria linked to "Hofmeister" but different from volume and valency.

Energy transfer: a spectroscopic ruler.
TL;DR: Electronic excitation energy transfer as function of distance measured, noting energy transfer process use as spectroscopic ruler as well as the use of spectroscopy ruler for measuring distance.

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.
