Experimental Methods for Studying Fractal Aggregatesnsity correlation functions. In a real physical system, such behavior has two natural limits: the particle or pore size and the cluster size. Within these limits, the system is well described by a fractal or Hausdorff dimension. For the experimentalist, it is important to find methods which can isolsynovium 发表于 2025-3-30 16:22:08

Aggregation of Colloidal Silica addition of sufficient salt. The resulting aggregates appear to be fractal, scale invariant objects, as determined by classical light scattering. Studies carried out in 0.5. NaCl show that the fractal exponent characterizing the clusters is 2.08±0.04 over a wide range of pH, and that the aggregatio剧毒 发表于 2025-3-31 00:29:42

Light Scattering from Aggregating Systems: Static, Dynamic (QELS) and Number Fluctuationshniques. At present the study has been limited to slow (reaction limited) aggregation (in 0.15 M NaC1). Preliminary measurements show an exponential like growth of both the mean scattered intensity and the mean hydrodynamic radius R.
