Coulomb charges

The other term that is very widely used is a Coulombic charge interaction of the form... 

The anode capacity is the total coulombic charge (current x time) produced by unit mass of an anode as a result of electrochemical dissolution. It is normally expressed in ampere hours per kilogram (Ah/kg) although the inverse of anode capacity, i.e. the consumption rate (kg/Ay) is sometimes used. 

One characteristic feature of surfactants is their amphiphilic nature. These molecules present two moieties the hydrophobic moiety (usually a hydrocarbon chain) interacts with the nanotube sidewalls, while the hydrophilic part, called polar head group, is generally charged or has zwitterionic character. It has the double function of helping solubility in aqueous solvents and of providing additional stabilization towards tubes aggregation by coulombic charge repulsion.

Another interesting example is the chaotic autoionization of molecular Rydberg states caused by the interaction of the electron with the degrees of freedom of the core. We consider the model in which the core consists of a positive Coulomb charge plus a rotating dipole that lies in the same plane of the electron orbit (m = l). The Hamiltonian reads (atomic units)... 

The implementation of this methodology proved to eliminate the errors associated with the force inconsistency of the Coulombic charge interactions. One critical step in the application of this technique is the choice of a proper population analysis scheme. Simple test computations can indicate which of the many schemes is suitable for a specific problem. 

Electropositive. Having or capable of assuming a positive coulombic charge a condition of electric charge associated with a loss of electrons or a surplus of positive over negative unit charges.
