The same product has been obtained before with the aid of the Joule-Lenz formula applied to the electron transition energy considered as a dissipation energy in the atom.doi:10.1166/qm.2016.1372Stanisaw OlszewskiQuantum Matter

An empirical formula was used to describe the coverage dependence of the binding energies. We used the newly determined binding energy distributions in a simulation of gas-grain chemistry for cold cloud and hot core models. We found that owing to the higher value of desorption energy in the ...
24,41 An RCS can be visualized as an extended defect along a close-packed row of atoms. When the first atom is pushed off its site, it dissipates some energy and pushes a second atom into a third, and so on. When the last atom in this chain is unable to displace another, it is...
The empirical binding energy -16Z''7''/''3 eV of heavy atoms is computed by a Hartree-type correction to a linearized version of the Thomas-Fermi model; the computations are carried out by means of a variational approach. Corrections to the exchange energy are also estimated. (authors)关键...
The total energies of the compound and its constituent elements can be obtained using quantum mechanical calculations such as density functional theory (DFT) or ab initio methods. Note that the formation energy is typically calculated per atom or per formula unit. The lower the formation energy, ...
Cryo-electron microscopy (cryo-EM) extracts single-particle density projections of individual biomolecules. Although cryo-EM is widely used for 3D reconstruction, due to its single-particle nature it has the potential to provide information about a biomo
we need to know the energy content or heat of combustion of the material. The total energy of a molecule is equal to a first approximation to the sum of the energies of the atom to atom bonds. Thus the energy of carbon dioxide (CO2), which is equal to −380 kilocalories/mole, may...
projectile at the screened potential of the target atom. On the basis of a Thomas Fermi-type screened potential, Lindhard, Scharf, and Schiott (LSS-model) found a universal dependence of the stopping cross section when energy and range are measured in reduced Thomas Fermi units (Schiott, ...
