Advanced Functional Materials, EarlyView.With a charge‐ion coupling engineering strategy, a K+/vacancy disordered K0.5Mn0.8Co0.1Ti0.1O2 material has been designed. The targeted transition metal doping disrupts charge ordering and inducing K+/vacancy disordering, thereby enabling rapid K+ diffusion through interconnected channels and a stable solid‐solution reaction mechanism.

Electrostatic fields in ionography
Medical Physics, 1975There is renewed interest in diagnostic radiology in electrostatic methods of imaging, such as xeroradiography and ionography. This is due to the fact that edge contrast can be achieved, aiding in the visualization of soft tissue tumors. In analyzing the image forming properties of these systems, we chose to solve the electrostatic problems by the ...

Extended Systems in Electrostatic Fields
Zeitschrift für Physikalische Chemie, 2010Abstract The basic principles behind a theoretical method for treating infinite, periodic systems exposed to an external electrostatic field are outlined. The approach, based on the vector-potential description of the external field, leads to single-particle Hartree-Fock or Kohn-Sham equations that differ from the ...

Ionospheric electrostatic fields
Journal of Atmospheric and Terrestrial Physics, 1977Abstract A pertubation-theoretical method has been used to solve the ionospheric potential equation of the dynamo-theory. The ionospheric large-scale electrostatic potential and force fields are given in analytical expression depending on the coefficients of an appropriate expansion of the wind fields. Numerical and graphical examples are given.

Fundamentals of Electrostatic and Quasi-electrostatic Fields
2020This chapter explains the fundamental characteristics of the electrostatic and quasi-electrostatic fields that the book covers. It deals with basic equations, boundary conditions, and the effects of conduction, among others. The “uniqueness theorem” in electric fields is also explained.

In this chapter we shall be concerned with systems in which the charge distribution is static, residing on fixed bodies. The general expressions that we have obtained for the field intensities and potentials become very much simplified by the restriction to static systems.

Electrostatic field calculations
Journal of Electrostatics, 1991Abstract Field calculations are required in electrostatics in order to determine the energy and force distributions. These calculations are rendered difficult because the geometry of the field is generally only loosely connected with the shape of the conductors and insulators.

In general the term electromagnetism deals with the mutual interaction of electrical charges. When the charges are stationary, we have problems on electrostatic fields and forces. If the charges are moving uniformly so that a steady current is produced, then we have problems on magnetic fields and forces (see chapter 3).

Automatic Plotting of Electrostatic Fields
Review of Scientific Instruments, 1948An apparatus is described by means of which plots of the equipotentials of two-dimensional fields may be made automatically from models of the electrodes. The usual electrolytic tank method has been extended by the addition of a servomechanism which causes the probe to traverse an equipotential automatically. A stepping relay operated by a limit switch
