Direct Force Measurement between Surfaces Coated with Hydrophobic Polymers in Aqueous Solutions and the Separation of Mixed Plastics by Flotation
… (PP), and Teflon showed the existence of long-range attractive forces (or hydrophobic force) that cannot be explained by the classical DLVO theory. The surface force measurements were conducted in pure water and in solutions of surfactant (alkyltrimethylammonium chloride) and a salt …

A comprehensive solvation theory for colloidal forces with application to both neutral and charged systems
… functional theory confirmed the existence of a long range attraction with electrostatic origins, and demonstrated that trends similar to experimental results could be predicted. It is important to note that electrostatics can be thought of as a subset of the solvation theory, and ions should be …

Investigation of Non-DLVO Forces using an Evanescent Wave Atomic Force Microscope
… from Si3N4 tips was used to re-examine short range hydration forces between hydrophilic surfaces. Results presented in this thesis suggest this force does not depend on the hydrated radius of the ion between glass and silicon nitride. The scattering generated by a Si3N4 tip has also been used …

Surface Forces between Silica Surfaces in CnTACl Solutions and Surface Free Energy Characterization of Talc
… and degassed C₁₈TACl solutions. The attraction decreased with NaCl addition, and was the strongest at the point of charge neutralization (p.c.n.) of silica substrate. The force measurement results obtained in C<sub>n</sub>TACl solutions showed that the attractions decayed …

MULTI-AGENT SOURCE LOCALIZATION USING PASSIVE SENSING
… The social behaviours are inspired from the long-range attraction and the short-range repulsion behaviours of a fish. The second source localization algorithm assumes an adaptive individualistic behaviour while keeping the social behaviours static. Finally, the third source localization …

AFM surface force measurements between hydrophobized gold surfaces
… Still other investigators3, 4 suggested that the long-range attraction observed between hydrophobic surfaces is due to the correlation between the patches of adsorbed ionic surfactant and the patches of unoccupied surface. For this theory to work, it is necessary that the charged patches be …
