Query: Long-range attractive tail of colloid interaction   To describe rich phenomena of dilute dispersions of highly-charged colloid
particles, it is necessary to modify the long-range electric part of the DLVO
potential. The screened Coulomb potential of pure repulsion obtained from the
Helmholtz free energy in the DLVO theory is replaced by a new screened electric
potential with long-range attractive tail derived from the generalized Gibbs
free energy which is identified with a total sum of chemical potentials.
