Microemulsions, as thermodynamically stable mixtures of oil, water, and surfactant, are
known and have been studied for more than 70 years. However, even today there are still …

The concepts “hydrotrope” and “hydrotropy” are reviewed with a strong focus on the
literature from recent years. The action and physical–chemical behavior of hydrotropes are …

Ternary solutions containing one hydrotrope (such as ethanol) and two immiscible fluids,
both being soluble in the hydrotrope at any proportion, show unexpected solubilization …

Recycling chemistry of metals and oxides relies on three steps: dissolution, separation and
material reformation. We review in this work the colloidal approach of the transfer of ions …

Ion-specific effects on the solubility of nonpolar solutes and on the solute–solute
hydrophobic interaction in aqueous electrolyte solutions are studied on the basis of a …

We study the surface tension of ionic solutions at air/water and oil/water interfaces by using
field-theoretical methods and including a finite proximal surface-region with ionic-specific …

We investigate the critical behavior of a near-critical fluid confined between two parallel
plates in contact with a reservoir by calculating the order parameter profile and the Casimir …

We present a continuum theory of electrolytes composed of a waterlike solvent and
univalent ions. First, we start with a density functional F for the coarse-grained solvent …

We study the surface tension of electrolyte solutions at the air/water and oil/water interfaces.
Employing field-theoretical methods and considering short-range interactions of anions with …

In this work, we review shortly the current state of knowledge about catanionic surfactant
systems with a focus on the detailed understanding based on the molecular buildup of such …
