This paper is organized as follows in Section 2, after a review of the relevant aspects of the Turing instability, we consider different aspects of the DIFICI. The differential flow instability in systems without an activator, DIFIRI, is described in Section 3, and Section 4 deals with some applications of the differential flow induced instabilities. 

The Differential Flow Induced Chemical Instability (DIFICI) of Activator-Inhibitor Systems... 

The necessary condition for the differential transport induced instabilities - the DIFICI and Turing instability (TI) - is the existence of an unstable subsystem, an activator [2,3,4,7,8]. The physical cause of these instabilities is the following the differential transport of activator and inhibitor, be it through a differential flow (DIFICI) or through differential diffusivity (TI), spatially decouples the counteracting species, and thereby releases locally the natural tendency of the activator to grow.
