This will be elaborated in detail in the following section. However, it is of interest that the existence of concentration-dependent (implying a far-from-equilibrium condition) cross-diffusion terms creates a non-linear mechanism between elements of the system, i.e. the flux of one polymer depends not only on its own concentration gradient but also on that of the other polymer component. This is consistent with two of the criteria required for dissipative structure formation. Furthermore, once a density inversion is initiated, by diffusion, it will be acted upon by gravity (as the system is open ) to produce a structured flow. The continued growth, stability and maintenance of the structures once formed may depend on the lateral diffusion processes between neighbouring structures. 

These examples of crystal studies in the expl field are but a few of many applications that have been reported. Propellants, primers, pyrotechnics many HE s have been greatly improved by the development of processes which control crystal growth stability of the individual fnaterials.

In semibatch emulsion polymerizations the polymer particles are kept monomer-starved to obtain higher rates of polymerization and to permit easier control of the rate and particle size distribution. There are two aspects to the control of PSD. The controlled addition of emulsifier during particle growth stabilizes the particles without further particle nucleation. The second aspect is related to the particle sticky stage which often occurs...

Multiple. sample capabilities. Plant studies routinely require examination of many. samples, particularly when the objectives of the study include identification of phenotypes with desired growth, stability, or yield characteristics. Screening large populations for individuals with desired metabolic characteristics is impossible in single-sample calorimeters. Current commercial multiwell calorimeters allow up to three samples to be run simultaneously. A calorimeter with as many as 100 sample wells could be effectively employed for plant studies.
