Interaction forces between oil-water particle interfaces--non-DLVO forces.
The interaction force between a rigid silica sphere and a butyl or octyl acetate droplet was measured in an aqueous environment using atomic force microscopy (AFM). The force measurements were performed without added stabilizers and the observed force behavior was found to be dependent on the type of inorganic electrolyte present, where the interfacial tension was constant over the electrolyte ...
متن کاملCapillary fluctuations and film-height-dependent surface tension of an adsorbed liquid film.
Our understanding of both structure and dynamics of adsorbed liquids heavily relies on the capillary wave Hamiltonian, but a thorough test of this model is still lacking. Here we study the capillary wave fluctuations of a liquid film with short-range forces adsorbed on a solid exhibiting van der Waals interactions. We show for the first time that the measured capillary wave spectrum right above...
متن کاملOverview of DLVO Theory
Derjaguin, Landau, Vervey, and Overbeek (DLVO) developed a theory of colloidal stability, which currently represents the cornerstone of our understanding of interactions between colloidal particles and their aggregation behavior. This theory is also being used to rationalize forces acting between interfaces and to interpret particle deposition to planar substrates. The same theory is also used ...
متن کاملA pressure-induced strength transition in water-saturated geologic materials
Porous, water-saturated geologic materials exposed to shock wave loading should undergo a gradual transition from a Terzaghi solid to a much stronger and stiffer material as the confining pressure increases over the range of about 0.2 GPa to about 2 GPa. This transition can thus be expected to become important in cases such as high explosive or nuclear cratering events in which ground shocks in...
متن کاملModel of the dielectric relaxation based on the reorientation of adsorbed water in wood cell wall
In order to clarify the molecular mechanism of the reorientation of adsorbed water in wood cell wall during dielectric relaxation process, the temperature and frequency spectrums of the dielectric relaxation process based on adsorbed water in wood, acetylated wood and formaldehyde-treated wood were measured, respectively, within a range of -60-20°C, 30Hz-3MHz and 0-27%m.c. On this basis, the qu...
