Abstract:

There were several major results in this project. We determined the unusual kinetics of simple heterogeneons reactions in which the mobility or velocity of each reactant is drawn from a distribution. We also elucidated the rich variety of kinetics in reactions where particles move on ballistic trajectories. Next, we mapped out the kinetics of a simple catalysis model on a disordered surface. Enhanced reactivity was discovered which arises specifically from the surface disorder. Third, we found surprising behavior in the kinetics and spatial organization of reactants in two-species annihilation, A B right arrow O, when all particles move in the same direction. We then investigated the coarsening kinetics of a system of growing and competing domains which can be viewed as a toy model of war. Finally, we describe advances in a number of physical realizations of aggregation and annihilation.
