Boundary Charge Layer and Current for Spherical Inclusion in Conducting System

Electric Double-Layer Interaction between Dissimilar Charge-Conserved Conducting Plates.

Small metallic particles used in forming nanostructured to impart novel optical, catalytic, or tribo-rheological can be modeled as conducting particles with equipotential surfaces that carry a net surface charge. The value of the surface potential will vary with the separation between interacting particles, and in the absence of charge-transfer or electrochemical reactions across the particle s...

Boundary Terms and Noether Current of Spherical Black Holes

We consider two proposals for defining black hole entropy in spherical symmetry, where the horizon is defined locally as a trapping horizon. The first case, boundary terms in a dual-null form of the reduced action in two dimensions, gives a result that is proportional to the area. The second case, Wald’s Noether current method, is generalized to dynamic black holes, giving an entropy that is ju...

Production of [18F] fluoride with a high-current two layer spherical gold target

Background: Fluoride-18 is the most widely used radioisotope for Positron Emission Tomography (PET). [18F] 2-flouro- 2-deoxy D-glucose (FDG) has become a standard tool in the area of clinical research. The oxygen-18 enriched water is the most widely used target for the production of fluoride-18. The use of the nuclear reaction 18O (p,n)18F has been found as the most effective method for the pro...

An Upper Limit for Birefringence in the Boundary Layer of a Heat Conducting Gas

The Waldmann-Vestner theory for boundary layer effects in polyatomic gases in the nearhydrodynamic regime predicts that in a rarefield heat conducting gas the boundary layers will be birefringent due to the presence of second rank angular momentum polarization. An experiment has been set up in order to measure the birefringence as a function of the distance to the boundary. However, no effect c...
