Colloid aggregation is the prototypical example of a random process which generates highly ramified dendritic structures. Although the qualitative features of aggregates have been well known, it was the recent discovery by Witten and Sander' of a computer simulation technique for diffusion-limited aggregation that spawned renewed interest in the structure of these curious objects. The Witten-Sander (WS) model and most subsequent modifications suggest that clusters possess universality in the…

Two-dimensional colloidal aggregation: concentration effects.

In the DLCA and in the flocculation regime, it was found that the fractal dimension shows a linear-type increase with the concentration phi, following the law: d(f)=d(fo)+aphi(c).

Tenuous Structures from Disorderly Growth Processes

Colloidal aggregation and other random growth processes produce structures that behave differently from ordinary bulk matter, many of which can be understood by using simple statistical principles.

Aggregation kinetics in two dimensions: Real experiments and computer simulations

The aggregation of silanized glass spheres (75±5 μm diam) was studied experimentally at liquid–air (water–air, aqueous surfactant solution–air, and aqueous glycerol solution–air) interfaces from a

Two-Dimensional Clusters of Colloidal Particles Induced by Emulsion Droplet Evaporation

The structure of two-dimensional clusters of colloidal particles bound at the interface of liquid droplets in the plane is studied and it is found that, differently from the three-dimensional system, the two- dimensional clusters have multiple degenerate configurations (isomers).

Comparison of aggregation of rodlike and spherical particles: A fractal analysis

Different structure-analyzing methods were applied to experimental and computer generated two-dimensional clusters. The real structures formed at water–air interfaces from polydisperse,

Diffusion-limited aggregation-like structure induced in Co thin films by carbon ion implantation

Fractal structure of a diffusion-limited aggregation (DLA) type was observed in a Co thin film after 50 keV carbon ion implantation to a dose of 2.5*1017 cm-2 at room temperature. The authors
