Specifically, the Coulomb potential associated with this force.

The particle-particle mesh Ewald method was used for the long-ranged Coulombic interactions. A cutoff of 12 A was used for the van der Waals interactions and short-ranged Coulombic interactions.
Various methods to incorporate siRNA into the stent surface have been developed, because siRNA is a negatively charged polymer and can bind to cationic polymers or a cationized surface through Coulombic interactions [16-18].
The electrostatic potential energy is represented as a pairwise summation of Coulombic interactions as described in Equation 4 [17]:
When secondary interactions, such as coulombic interactions by acidic silanols (silica compounds) or metal impurities in the stationary phase, exist to a large extent, peak shapes of proteins will deteriorate due to their slow kinetics.

Secondly, we used force field based simulation for the adsorption isotherm generation in which nonbonded interactions like van der Waals and coulombic interactions were considered.
In other words, the default methods are Ewald summation for van der Waals interacting and for Coulombic interactions (Figure 11).
Coulombic interactions are the dominant force between the ions, including dipole, hydrogen-bonding and dispersive forces are also important to the interactions between constituents in the ILs (Tokuda et al.
Sun and Stirner (2001) used molecular dynamics to study the compression of 2-D polystyrene particles at an oil-water interface through monopole-monopole Coulombic interactions. Moncho-Jorda et al.
