A Coulombic explosion is a condensed-matter physics process in which a molecule or crystal lattice is destroyed by the Coulombic repulsion between its constituent atoms. Coulombic explosions are a prominent technique in laser-based machining , and appear naturally in certain high-energy reactions.
Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest.
In chemistry, bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more fragments. [1] In general, there are two classifications for bond cleavage: homolytic and heterolytic, depending on the nature of the process.
A visual and tactile classroom model of strong close-range attraction and far-range repulsion characteristic of the fusion potential curve is modeled in the magnetic “Coulomb” barrier apparatus. [3] The apparatus won first place in the 2023 national apparatus competition of the American Academy of Physics Teachers in Sacramento, California.
In chemistry, it is expressed as the energy to ionize a mole of atoms or molecules, usually as kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). [3] Comparison of ionization energies of atoms in the periodic table reveals two periodic trends which follow the rules of Coulombic attraction: [4]
Pictorial representation of two interacting charged plates across an electrolyte solution. The distance between the plates is abbreviated by h.. The most popular model to describe the electrical double layer is the Poisson-Boltzmann (PB) model.

A well-studied example is the radical ion salt TTF-TCNQ with a conductivity of 5 x 10 2 Ω −1 cm −1, [5] much closer to copper (ρ = 6 x 10 5 Ω −1 cm −1) [8] than many molecular solids. [31] [18] [30] The coulombic interaction in TTF-TCNQ stems from the large partial negative charge (δ = -0.59) on the cyano- moiety on TCNQ at room ...
