Bone Mineral and Surface Charge

Clinical Orthopaedics and Related Research, 1977
A triple association has been observed between a high negative surface charge, bone morphogenetic activity, and in vitro recalcificaiton in implants of demineralized bone matrix. Proplast fills with bony tissue when implanted in the body and shows the same triple association.

Charged Surfaces and Interfacial Ions

Journal of Colloid and Interface Science, 2000
Interfacial charge in a solid/liquid system is due to interactions of ions with surface sites affected by the electrostatic potential that is a consequence of their accumulation. The present theoretical approach is based on the so-called Surface Complexation Model that has several modifications known as either the 1-pK, the 2-pK, or the "MUSIC" model ...

Image charge at a metal surface

Physical Review B, 1985
On montre que la densite de charge d'echange moyenne n'est pas localisee dans la region de surface a la limite asymptotique, lorsque l'electron est a l'exterieur, tres eloigne et possede une largeur variant avec la position de l'electron par rapport a la surface.

Surface charge and asbestos toxicity

Nature, 1977
ASBESTOS is a serious occupational and environmental hazard because of its fibrogenic and carcinogenic actions on the lung. Asbestos fibres exist in various physical forms, all of which are toxic. It is not known, however, which form is the most hazardous or which fibre property is the most important for inducing the toxic effects. It is thus important

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.
