What's the difference between dispersion and dissipation?

Dispersion


Definition:

  • (n.) The act or process of scattering or dispersing, or the state of being scattered or separated; as, the Jews in their dispersion retained their rites and ceremonies; a great dispersion of the human family took place at the building of Babel.
  • (n.) The separation of light into its different colored rays, arising from their different refrangibilities.

  • (19) It appears, therefore, that the aggregation and dispersion of pigment within the melanophores is the primary mechanism responsible for the changes in color of this species.
  • (20) When detergent-dispersed LA was contaminated with linoleic acid hydroperoxide (LOOH), lipid peroxidation was catalyzed by Fe2+ via reductive cleavage of LOOH (LOOH-Fe2+-induced lipid peroxidation), and Fe2+ was oxidized simultaneously in SDS micelles, even when H2O2 was not present.

Dissipation


Definition:

  • (n.) The act of dissipating or dispersing; a state of dispersion or separation; dispersion; waste.
  • (n.) A dissolute course of life, in which health, money, etc., are squandered in pursuit of pleasure; profuseness in vicious indulgence, as late hours, riotous living, etc.; dissoluteness.
  • (n.) A trifle which wastes time or distracts attention.

Example Sentences:

  • (1) The rhodamine 123-induced growth inhibition was partially reversed by treating the dye-pre-exposed infected erythrocytes with the proton ionophore carbonyl-cyanide m-chlorophenylhydrazone, which dissipates transmembrane proton gradients.

  • (3) It has been possible to separate this dissipation from that associated with elongation factor Tu function.
  • (4) A mutation from one state into another in such system ('bioids') involves an amplification of different 'kinds of information', as 'stochastic' (noise into dissipative structures), 'molecular' (autocatalysts), and 'stoichimetric' information.
  • (5) A comparison with the same transient input terminal input, the fraction of input charge dissipated by various branches in the neuron model is illustrated.
  • (6) Therefore, at least 75% of maximal import inhibition observed in the presence of F1 beta 1-32 + 2 and F1 beta 21-51 + 3 does not result from dissipation of delta psi.
  • (7) The surreal air of calm surrounding Spain's bond market shows no signs of dissipating.
  • (8) In the present studies, Cl replaced the much less permeant anion methanesulfonate (Mes) either (a) at constant [K], in which increased [K][Cl] permits net KCl and water flux across internal membranes, or (b) at constant [K][Cl] (choline substitution), in which the imposed gradients and diffusion potentials should dissipate slowly.
  • (9) Similarly, the formation of spatial dissipative structures by coupling of a transport process with an interfacial reaction was investigated as a simple experimental example of symmetry breaking.
