11. Solving Poisson's equation for the potential requires knowing the charge density distribution. 12. For an application of this integral see Charge density spread over a wave function. 13. It is a high charge density cationic polymer. 14. Is it possible to calculate a maximum possible charge density for a black hole? 15. Charge density waves are a related phenomenon.16. The wall's charge density is proportional to the pH of the buffer solution. 17. The surface charge density on the sphere is the difference between the radial field components: 18. If the charge density follows a Boltzmann distribution, then the Poisson-Boltzmann equation results. 19. The highly negative charge density of heparin contributes to its very strong electrostatic interaction with thrombin. 20. These types of exchangers can maintain their charge density over a pH range of 0 14.
