Fractal geometry of colloidal aggregates
TLDR
In this article, the fractal dimension of colloidal aggregates of small silica particles is measured by both light and x-ray scattering, showing that the aggregates are fractal.Abstract:
Measurement of the fractal dimension, $D$, of colloidal aggregates of small silica particles is reported. We observe power-law decay of the structure factor $[S(k)\ensuremath{\sim}{k}^{\ensuremath{-}D}]$ by both light and x-ray scattering showing that the aggregates are fractal. $D$ is found to be 2.12\ifmmode\pm\else\textpm\fi{}0.05, which is intermediate between recent numerical results for the kinetic models of diffusion-limited aggregation ($D=2.5$) and cluster aggregation ($D=1.75$), but is rather close to the value for lattice animals ($D=2.0$), which are equilibrium structures.read more

Light Scattering by Fractal Aggregates: A Review
TL;DR: In this article, the authors present a review of scattering and absorption of light by fractal aggregates, which are typically diffusion limited cluster aggregates with fractal dimensions of D.

Flow phenomena in rocks : from continuum models to fractals, percolation, cellular automata, and simulated annealing
TL;DR: In this article, theoretical and experimental approaches to flow, hydrodynamic dispersion, and miscible and immiscible displacement processes in reservoir rocks are reviewed and discussed, and two different modeling approaches to these phenomena are compared.

Universality in colloid aggregation
TL;DR: In this article, the authors investigated the aggregation of three chemically different colloidal systems under both diffusion-limited and reaction-limited aggregation conditions and provided convincing experimental evidence that the two regimes of aggregation are indeed universal.
