Fractal Characterization of the Structure of Aerosol Agglomerates Grown at Reduced Pressure

Abstract
Experimentally grown metallic aerosol particles were found to form highly complex shapes. When the ambient pressure at which they were grown was decreased, distinctive changes in their appearance were observed. Fractal analysis was used to characterize these particles and their differences. The analysis was able to distinguish several different growth regimes and explain some of the growth-pressure effects.
