In relation to satellite applications like global navigation satellite systems (GNSS) and remote sensing, the electron density distribution of the ionosphere has significant influence on trans-ionospheric radio signal propagation. In this paper, we develop a novel ionospheric tomography approach providing the estimation of the electron density’s spatial covariance and based on a best linear unb...

In this study interaction of phenothiazine sulfur dye with (5, 5) armchair open-end boron nitride nanotubes (BNNTs) in interaction (with a length of 7 Å) was investigated. The impacts of the estereoelectronic effect associated with donor-acceptor electron delocalizations, dipole-dipole interactions and total steric exchange energies on the structural and electronic properties and reactivity of ...

The Hohenberg-Kohn theorem states that the ground state electron density completely determines the external potential acting on an electron system. Inspired by this fundamental theorem, we developed a novel approach to map directly the electron potential in surface systems: linear response theory applied to the total electron density as measured with scanning tunneling microscopy determines the...

Visible and near-infrared electron–ion bremsstrahlung measurements in fusion research devices, used to determine the effective ionic charge (Zeff), are often plagued by pollutant emission from the cool-edge region. The primary sources of visible and near-infrared non-bremsstrahlung continuum emission in the Madison Symmetric Torus arise from electron–neutral interactions, and the pollutant emis...

in this study, the adsorption of 4-hydroxy phenyl-azobenzene on the surface of (4, 0) zigzag open-end boron nitride nanotube (bnnt) has been investigated by quantum calculations. in order to find the preferred adsorption site, different positions and orientations were considered. the impacts of donor-acceptor electron delocalization on the structural and electronic properties and reactivity of ...

Within the context of the total electron density distribution, a well-defined set of radii known as bonded radii can be derived by measuring, along the bond path, the distance between the center of an atom and the point of minimum electron density. As the properties of a crystal, including its total energy, are determined by its electron density distribution, such radii provide an objective mea...
