An analytical solution for the distribution of surface charge on a dielectric sphere due to the presence of an external point charge is presented. This solution describes how charge on the surface of the sphere is polarised in the electric field into regions of negative and positive charge. The polarisation effect (distribution of surface charge) generally varies with the separation between the...

High-resolution atomic force microscopy is used to map the surface charge on the basal planes of kaolinite nanoparticles in an ambient solution of variable pH and NaCl or CaCl2 concentration. Using DLVO theory with charge regulation, we determine from the measured force-distance curves the surface charge distribution on both the silica-like and the gibbsite-like basal plane of the kaolinite par...

An insulator surface charge may be responsible for flashover along the surface. In this study, experimental investigations of post are performed using a variety voltage, gas type, and pressure conditions. Combining model transport, dominant transition is revealed considering partial discharge. The results show that hetero-polar accumulates near high voltage electrodes on at one atmospheric with...

T HE SURFACE CHARGE OF MAMMALIAN CELLS is considered to be one of several factors determining the balance between attractive and repulsive forces that operate between the cell periphery and other surfaces of potential contact.1’2 The surface-charge density of the leukocyte may be important in determining surface characteristics such as adhesiveness, deformability, and pseudopod formation. Varia...

The streaming potentials of two different nanofiltration membranes were studied with several electrolyte solutions to investigate the influence of salt type and concentration on the zeta potential and kinetic surface charge density of the membranes. The zeta potentials decreased with increasing salt concentration, whereas the kinetic surface charge densities increased. The kinetic surface charg...

We have examined the adsorption behaviors of carbon monoxide (CO) molecule on TiO2 anatase supported Au overlayers. The results of density functional theory (DFT) calculations were used in order to gain insights into the effects of the adsorption of CO molecules on the considered hybrid nanostructures. We have investigated different adsorption geometries of CO over the nanoparticles....

The density and distribution of electric charge on the surface of rabbit bone marrow cells was visualized by electron microscopy after the cell surfaces had been stained with charged colloidal iron particles. Expulsed erythroid nuclei are less negatively charged than any other cell in the bone marrow. They carry from about one-half to one-third of the charge density on the remaining future reti...
