When Ion-Ion Correlations are Important in Charged Colloidal Systems
Colloidal particles, biopolymers and membranes all carry charges in an aqueous environment. The molecular source of these charges can be cova-lently bound ionic groups like phosphates, sulfates, carboxylates, ...

Role of hydration and water structure in biological and colloidal interactions
The conventional explanation of why hydrophilic surfaces and macromolecules remain well separated in water is that they experience a monotonically repulsive hydration force owing to structuring of water molecu...

Difference Versus Gaussian Curvature Energies; Monolayer Versus Bilayer Curvature Energies; Applications to Vesicle Stability
The recent discovery that the electrostatic contribution to the curvature free energy G c of a membrane has, exactly to second order in the principle curvatures c ...

Adhesion and Fusion of Amphiphilic Surfaces: Role of Hydrophobic, Hydration and Steric Forces
We have measured the forces that determine the adhesion and fusion of bilayers. The aim was to clarify the roles of repulsive (electrostatic, hydration, undulation and steric) forces, and attractive (van der W...

Temperature Dependence of the Phase Equilibria in the PEG-Dextran System — A Theoretical and Experimental Study
In a previous paper we have concluded that polymer incompatibility in aqueous two-polymer systems are due to an unfavourable segment-segment interaction between the two polymers. In order to further study the ...

Structure and Dynamics of Micelles and Microemulsions
The surface of amphiphilic aggregates consists of amphiphile head-groups, counterions and water molecules while the interior mainly contains the hydrocarbon chains. A review of the structure and dynamics of di...

The Association of Ionic Surfactants to Micelles and Liquid Crystalline Phases: A Thermodynamic Model
A model for the association behaviour of ionic surfactants is presented, in which it is emphasized that the formation of micelles in a dilute aqueous solution is but a first step in a continuing association pr...

Molecular and Ionic Behaviour at Water-Amphiphile Interfaces
In systems containing aggregates of amphiphilic compounds there is a spatial separation between the hydrocarbon chains and the water molecules. The decisive feature is the interface betwen the two distinctly d...
