Differences in activities in colloidal particles are sufficient to drive phase separation between active and passive (or less active) particles. even if they have only excluded volume interactions. In this paper. we study the phase-separation kinetics and propose a theory of phase separation of colloidal mixtures in the diffusive limit. https://ocpgixah9e0wcr.dsiblogger.com/67920626/bookchin-s-libertarian-municipalism
