Nb. Ming et al., NUCLEATION-LIMITED AGGREGATION IN FRACTAL GROWTH, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(1), 1993, pp. 621-624
In situ observation technique is employed to study the fractal growth
in a thin isothermal aqueous-solution film of Ba(NO3)2. The micromorph
ology and the growing process of the fractals have been investigated.
The experimental findings provide direct evidence that the fractals ar
e formed by random successive nucleation. A nucleation-limited-aggrega
tion (NLA) model is proposed to describe the fractal growth in our sys
tem. A computer simulation using the NLA model is also presented.
