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:

Counterion effect on the aggregation of anionic perylene dyes and the influence on carbon nanotube dispersion efficiencies
TL;DR: In this paper, the effect of alkali metal counterions on the aggregation behavior of an anionic perylene dye has been investigated by absorption and emission spectroscopy, showing that in the presence of Na+ aggregation, a decreased surfactant capability for the dispersion of carbon nanotubes is obtained.
Journal ArticleDOI
Microgel-like aggregates of isotactic and atactic poly(methacrylic acid) chains in aqueous alkali chloride solutions as evidenced by light scattering.
TL;DR: Results suggest that under the same experimental conditions iPMA is effectively more charged than aPMA, and the role of ions in the slow-mode phenomenon is less pronounced than in aggregation.

Counterion Effect on Krafft Temperature and Related Properties of Octadecyltrimethylammonium Bromide
TL;DR: In this article, the effect of counterions on the Krafft temperature and micelle formation of octadecyltrimethylammonium bromide (OTAB) in aqueous solution was investigated.
Journal ArticleDOI
Effect of Hofmeister series anions on the thermotropic phase behavior of bioactive O-acylcholines.
TL;DR: A homologous series of OACs with even chain lengths are synthesized, and their thermotropic and chaotropic phase transitions have been characterized, revealing that in aqueous dispersion O-stearoylcholine undergoes a cooperative phase transition from a gel phase to a micellar structure and that the transition temperature increases when the counterions are changed in the Hofmeister series.

Salt-Induced Modulation of the Krafft Temperature and Critical Micelle Concentration of Benzyldimethylhexadecylammonium Chloride
TL;DR: In this paper, the effect of some sodium salts on the Krafft temperature and critical micelle concentration of benzyldimethylhexadecylammonium chloride (C16Cl) in aqueous solution has been studied.

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.
