A novel approach to 3D part segmentation is presented. It is a well-known physical fact that electrical charge on the surface of a conductor tends to accumulate at a sharp convexity and vanish at a sharp concavity. Thus, object part boundaries, which are usually denoted by a sharp surface concavity, can be detected by simulating the electrical charge density over the object surface and locating...

This investigation sets out to mimic protein-crystal interaction during biomineralization with the use of artificial proteins (dendrimers). It is hypothesized that these interactions depend on the surface charge of hydroxyapatite crystals. This was investigated with the use of dendrimers with capped surfaces of different charges to probe the surface. We used AFM images of crystal-bound dendrime...

ABSTRACT Accurate characterization of membrane surface charge is vital for understanding membrane surface chemistry, separation performance, and fouling resistance. Streaming potential is the standard electrokinetic phenomena used to characterize a membrane’s isoelectric point and zeta potential, which is related to the dynamic charge functionality at the membranesolution interface as function ...

in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...
