A study of charge density in copper
Acta Crystallographica Section A: Foundations and Advances, 2005Quantitative convergent-beam electron diffraction (QCBED) experiments allow absolute scale measurements of low-order structure factors with very high accuracy. In this paper, eight low-order structure factors for copper measured by QCBED have been combined with the higher-order gamma-ray structure factors in order to obtain a larger highly accurate ...

Modern Charge-Density Analysis
2012This is the preface to the book by Philip Coppens : The contributions in this book manifest the tremendous developments that have taken place in the last 10-20 years in electron density research in the broadest sense. Although the possibility of measuring the distribution of electrons in crystalline solids with X-rays was realized soon after the ...

Charge density of renal interstitium
Acta Physiologica Scandinavica, 1993The charge density of renal interstitium was analysed from the volume of distribution of negative native albumin as compared with neutralized albumin, labelled with 125I and 131 I, respectively. The experiments were conducted by infusing the two probes intravenously at a rate which kept the plasma concentrations stable. The concentration in renal hilar

SUPERCONDUCTIVITY AND CHARGE-DENSITY WAVES
Physical Review B, 1979Publisher Summary Superconductivity (SC) and charge-density wave (CDW) are the two most well-known cases of broken symmetry in a solid, which require an effective attractive electron–electron interaction. That interaction is normally provided by a phonon-mediated mechanism.

Superconductivity and charge-density waves
Physical Review B, 1989Superconductivity in a metal with a charge-density-wave (CDW) brokensymmetry is investigated within the framework of Bardeen-Cooper-Schrieffertheory. The anisotropic gap equation for /Delta/(/bold k/) is solvedanalytically. We find that whenever /bold k/ approaches a CDW energy gap,/Delta/(/bold k/) undergoes a sudden increase.

Valence charge density in aluminium
Journal of Physics F: Metal Physics, 1973A comparison is made between the valence charge density of A1 obtained using a local on Fermi sphere potential and that derived from a suitable average potential, which takes into account the effects due to the nonlocality of the pseudopotential. The two electron distributions present significant differences, showing that a calculation of the valence ...

An experimental charge density of HEPES
Acta Crystallographica Section B Structural Science, 2010We report the experimental charge density of HEPES [4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid], which is a common buffering agent. The structure was refined using the Hansen–Coppens formalism. The ability of the HEPES molecule to form stable intermolecular interactions and intermolecular hydrogen bonds in the crystal structure is discussed in ...

The Dynamics of Charge Density Waves
Reviews of Modern Physics, 1985In many materials with a highly anisotropic band structure, electron-phonon interactions lead to a novel type of ground state called the charge-density wave. The condensate is pinned to the underlying lattice by impurities and by boundary effects, but can, even for small electric fields, carry current in a fashion originally envisioned by Fr\"ohlich ...

American Journal of Physics, 1985
It is argued that in the teaching of electric circuits more emphasis needs to be placed on the basic physical ideas introduced earlier in electrostatics. Two lecture demonstrations are described which illustrate the point that electrical potential in a circuit is the same function of charge density distribution as it is in electrostatics.
