Limiting currents in planar crossedeld diodes have been studied for over 70 years [1][3] for B < BHull and more recently for B > BH [4]. Recent simulations of cylindrical crossedeld diodes for anode/cathode radius ratios of 2 and 5 indicate that the limiting current curve in cylindrical diodes follows the planar theory and simulations very closely [5]. Newer simulations for larger radius ratios...

An adjustment to 782 ground state nuclear charge radii for nuclei with N,Z ≥ 8 leads to R0 = 1.2257 A 1/3 fm and σ = 0.124 fm for the charge radius. Assuming such a Coulomb energy Ec = 3 5 eZ/1.2257 A 1 3 , the coefficients of different possible mass formulae derived from the liquid drop model and including the shell and pairing energies have been determined from 2027 masses verifying N,Z ≥ 8 a...

We consider electrostatic plasma modes along the open field lines of a rotating neutron star. Goldreich-Julian charge density in general relativity is analyzed for the neutron star with zero inclination. It is found that the charge density is maximum at the polar cap and it remains almost same in certain extended region of the pole. For a steady state Goldreich-Julian charge density we found th...

The coefficients of different mass formulae derived from the liquid drop model and including or not the curvature energy, the diffuseness correction to the Coulomb energy, the charge exchange correction term, different forms of the Wigner term and different powers of the relative neutron excess I = (N − Z)/A have been determined by a least square fitting procedure to 2027 experimental atomic ma...

Almost all proteins contain charged amino acids. While the function in catalysis or binding of individual charges in the active site can often be identified, it is less clear how to assign function to charges beyond this region. Are they necessary for solubility? For reasons other than solubility? Can manipulating these charges change the properties of proteins? A combination of capillary elect...

so far the static properties of hadrons have been introduced in various models. the static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. in this work we have introduced the hypercentral constituent quark and isospin dependent potentials. here constituent quarks interact with each other via a potential in which we have ta...

Scanning force microscopy was used to study localized charge deposition and subsequent transport in Co nanoclusters embedded in SiO2 deposited on an n-type Si substrate. Co nanoclusters were charged by applying a bias voltage pulse between tip and sample, and electrostatic force microscopy was used to image charged areas, to determine quantitatively the amount of stored charge, and to character...

Abstract In this paper, the phase structure of Hayward-AdS black hole (BH) is studied using shadow formalism. It has been found that radius a monotonic function horizon and can therefore play an equivalent role to in characterizing thermodynamics BH. The thermodynamic transition (PT) BH investigated with radius. shown as magnetic charge increases, becomes larger, while coexistence temperature l...
