Towards universality in the computer simulations of reaction limited colloid aggregation

An effort has been directed towards the obtainment of universal results in the computer simulations of reaction limited colloid aggregation. The used models try to follow as closely as possible the experimental situation, and coincide with different versions of the original clustering of clusters model, plus a very small bonding probability at each encounter between colloidal particles. Different effects have been previously reported when a variation was made of (a) the sticking probability, (b) the concentration, (c) the step length and (d) the number of times sticking is tested when there are several contacts between the clusters. In this note we give a brief account on how these different models have led us to desired uiversality.
