Corrections to the Debye-Hückel Theory
<p>The cluster expansion theory of Mayer is rearranged to obtain expressions for the potential of average force and the internal potential energy of the electron gas through order n<sup>3/2</sup> in the density n. The order n result for the potential of average force is applied to ionic solutions, …

X-ray Debye temperatures of solid neon
… These data have been interpreted in terms of two Debye characteristic temperatures, ~I by the ,method suggested by Nicklow and Young, and eM by the method due to Chipman. The specimens were prepared and maintained in a specially designed rigidtail liquid helium cryostat, and the measurements were …

The X-ray Debye temperature of solid krypton
… These data have been interpreted in terms of a Debye characteristic temperature, 8 M "" according to the method suggested by Nicklow and Young. The specimens were prepared and maintained in a specially designed and constructed rigid-tail liquid helium cryostat and the measurements were made with …

X-Ray Debye -Waller Factor Measurements of Helium Crystals
… mass-scaling factor of 4/3 for the equivalent Debye temperature for the measured Debye-Waller factor was observed. This Debye temperature falls with increasing temperature, contrary to what would be expected for a quasi-harmonic model, most likely due to multi-phonon processes being present in …

Prediction of electrolyte solution properties using a combined Debye-Huckel, association and solvation model
… long-range electrostatic ion-ion interaction (Debye- Hückel effects), short-range ion-ion interactions (ion association), and short-range ion-solvent interactions (hydration). The activity of water in NaCl, NaOH, and HCl solutions is fit with maximum deviations from experimental values of …

Transient electromagnetic scattering by a radially uniaxial dielectric sphere: Debye series, Mie series and ray tracing methods
… is explored using three well-known methods: Debye series, Mie series, and ray tracing theory.</p> <p>In the first approach, the general solutions for the impulse and step responses of a uniaxial sphere are evaluated using the inverse Laplace transformation of the generalized Mie series …

On the formulation and the calculation of the harmonic contributions to the Debye-Waller factor in metals (sodium)
… for the anharmonic contributions to the Debye-Waller factor up to 0(A ) and 0 L% ) £ where ^ is the scattering wave-vector] have been derived in a form suitable for cubic metals with small ion cores where the interatomic potential extends to many neighbours. This has been achieved in …

Nonideality of Single and Mixed Electrolyte Solutions Up to Moderately High Concentration; Theory Based on Debye-Huckel Radial Distribution Function
Because of the complex nature of the solvent effect and of the mathematical difficulty in the treatment of the Coulombic long-range force, the theoretical treatments of the equilibrium properties of the electrolyte solution are not fully developed if one compares with those of the non-electrolyte …

The separation was measured using interference microscopy and the adsorption of fluorescein was measured using fluorescence microscopy. The Debye-length was altered by variation of the background salt (NaCl) concentration in dilute (<1 …

Two dimensional particle-in-cell simulation model for Hall type thrusters
… forward, the simulation size was 50x20 Debye lengths. Cell size was half of the plasma Debye length, in both dimensions. Time step was based on the condition that the electron gyroradius be ten times the Debye length, for a given electron temperature of 10 eV and maximum magnetic field …
