An explanation for the charge on water’s surface

Physical Chemistry Chemical Physics, 2009
Measurements with different techniques point to a strong affinity of hydroxide ions for interfaces between water and hydrophobes, but some spectroscopic experiments do not detect excess hydroxide at the interface, while others do. Hydroxide ions are unusual in that they reduce the relative permittivity of an electrolyte solution more than other ...

Surface Charge Properties of Kaolinite

Clays and Clay Minerals, 1996
AbstractThe surface charge components of 2 Georgia kaolinites of differing degrees of crystallinity (KGa-1 and KGa-2) were determined using procedures based on charge balance concepts. Permanent structural charge density (σ0) was determined by measuring the surface excess of Cs, which is highly selective to permanent charge sites.

Microbial Adhesion to Surfaces with Different Surface Charges

Acta Odontologica Scandinavica, 1981
The adhesion behaviour of Streptococcus sanguis was studied on well-defined stearic and behenic acid multilayers which were prepared by depositing fatty acids on a solid substrate according to the Langmuir-Blodgett technique. Using this technique and by adjustment of the substrate pH it was possible to form outer surfaces consisting of either close ...

Surface charge, surface dipoles and membrane conductance

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1973
Abstract The conductance of lipid membranes in the presence of nonactin is changed by the adsorption of small amounts of ionic and zwitterionic surfactants. The conductance changes are, in many instances, not accounted for by the variation in surface charge or diffuse double layer potential as calculated from Gouy-Chapman theory.

Surface Discharge Propagation: The Influence Of Surface Charge

Conference Record of the 2006 Twenty-Seventh International Power Modulator Symposium, 2006
Surface discharges are of considerable importance, because of their influence on the reliability of high voltage pulsed power systems. It is possible to achieve long discharges with relatively low voltages particularly in the presence of surface charge.

Engineering Surface Charges in a Subtilisin

1996
Introduction of multiple charged amino acid residues in the subtilisin Savinase by genetic engineering allowed us to modify the electrostatic properties of this enzyme in a systematic way. The effects of these charge changes were investigated theoretically with the calculated electrostatic potential at the enzyme surface and experimentally using ion ...

Bone Morphogenesis and Surface Charge

Clinical Orthopaedics and Related Research, 1976
The electrophoretic mobility of variously treated bone specimens, with and without bone morphogenetic activity, has been measured in physiological solutions. The Bone Morphogenetic Principle appears to be associated with a minimum negative surface charge on the implant that corresponds to that of normal undemineralized cortical bone in saline ...

Charging of water at inert surface

2012
Electrokinetic measurements of bubbles (argon or nitrogen) in aqueous electrolyte solution obeyed negative surface charge (charge of stagnant interfacial water layer) in the region of pH > 3, and positive in the region pH < 3 [1]. This finding was interpreted as preferential accumulation of OH– ions at the surface, with respect to H3O+ ions ...
