Coulomb energy

Coulomb energy

[′kü‚läm ‚en·ər·jē]
(physics)
The part of the binding energy of a system of particles, such as an atomic nucleus of a solid, which is associated with electrostatic forces between the particles.
(physical chemistry)
The energy associated with the electrostatic interaction between two or more electron distributions in terms of which the actual electron distribution of a covalent bond is described.

It was noticed that studied PCNPs have different Glide score, Van der Waals energy, and coulomb energy which is apparent due to the structural difference between these natural pigments of same class.
Different bonding interactions are shown in Table 1 while from Table 2 it can be easily anticipated that meridine was best docked to CDK-6 with Glide energy of -44.78, Van der Waals energy of -41.76, and coulomb energy of -3.02.
Docking results clearly judged meridine (best Glide score, maximum H-bonds, and promising Van der Waals and coulomb energy between the ligand and receptor) to be a promising PCNP and it could be considered as potential "lead molecule" for the development of novel anticancer drugs.
Since our interest here is in estimating the lowest-order correction to the Coulomb energy, we will retain only the leading quadratic term in expression (22).
The two last terms in (2) are respectively due to the smooth part of the pairing energy and the correction of the Coulomb energy to account for the diffuseness of the nucleus surface.
The last correction to the Coulomb energy takes into account that the liquid drop has not a sharp but a diffuse surface of the Woods-Saxon type.
The Hamiltonian was simplified by linearising the intra-atomic Coulomb interaction with the Hartree-Fock approximation then the f-electron band energy was [E.sub.k] = [[epsilon].sub.f] + [Un.sub.[sigma]], where [[epsilon].sub.f] was bare f-electron energy and [Un.sub.[sigma]] was the Coulomb energy of f-electron.

Among specific topics are super-heavy and giant nuclear systems, an experimental program with rare-isotope beams at the international Facility for Antiproton and Ion Research (FAIR), quantum Monte Carlo calculations of light nuclei, tests of clustering in light nuclei and applications to nuclear astrophysics, shell-model calculations with low-momentum realistic interactions, studying nuclear structure by means of Coulomb energy differences, symmetry and super-symmetry in nuclear physics, and the microscopic study of multi-photon excitations in nuclei.
Among the theoretical works, Brown, Preston, and Singleton (BPS) produced an analytic calculation for Coulomb energy exchange processes for a fusion plasma [9, 16, 17].
