 (ko͞o′lŏm′, -lōm′)
n. Abbr. C
The basic unit of electric charge, equal to the quantity of charge transferred in one second by a steady current of one ampere, and equivalent to 6.2415 × 1018 elementary charges, where one elementary charge is the charge of a proton or the negative of the charge of an electron. A coulomb's value in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units. See Table at measurement.
adj. also cou·lom·bic (ko͞o-lŏm′bĭk, -lōm′-)
Of or relating to the Coulomb force.

Coulombic, Van der Waals and interactive energy (e.g., Grauer et al, 1987; Tahani et al., 1999) participate on the bonding of hydrated cations and therefore the alkali metals bonds are much inferior to their covalent bond in micas.
The existence of cationic (basic) and anionic (acidic) dyes in ink and their opposite Coulombic interactions with the capillary wall necessitated the development of two separate capillary electrophoresis methods (Egan et al.
The first term is a nuclear (Yukawa type) attractive potential and the second is the standard Coulombic repulsive term between the mother nucleus and the daughter alpha particle.
Electron backscatter is primarily the result of the electrostatic interaction of incident electrons with the Coulombic field of the atom (essentially the positive charge of the nucleus), which in turn is produced by the total charge of the protons (partially modified by the screening effect of the inner orbital electrons), which is related to the number of each, that is Z.
Noting interaction at the Fermi surface, the background idea canvassed is the establishment of an equilibrium involving the omnipresent Coulombic forces between orbiting electrons and nucleons.
Secondly, when the beam electrons undergo velocity deceleration in the Coulombic field of an atom, the energy loss is emitted as a photon of electromagnetic energy, called the Bremsstrahlung or "braking radiation." The random nature of the deceleration can result in any amount of energy loss, thereby forming a continuous electromagnetic spectrum.

Second, because of the l/r dependence of Coulombic energies, long force cut-offs are often used in organic simulations.
At this intensity, the electric field of alaser pulse that is shined on an atom is strong enough to compete for electrons with the nucleus's electric attraction, called the coulombic field.
The features of the modied CoO@Co nanoparticles include: coulombic efficiency, rate capability, cycling stability (55 cycles), and high catalytic activity.
Figure 7 shows the charge/discharge curves and Coulombic efficiency of carbon fiber anodes (samples P-1, P-2, and P-3) at a constant current density of 100 m A [g.sup.-1] over a potential window of 0.05-3 V.
