Fig. 4: Microscopic images of PS clusters and distribution of association number.
From: Clustering of charged colloidal particles in the microgravity environment of space
a Fluorescence micrographs of polystyrene (PS) clusters from the space experiment and magnified images of m = 1 to m = 4 clusters. b, c Distribution of the number of clusters m at various NaCl concentrations in the (b) space experiment and (c) ground experiment. d The plot of average cluster number <m> vs. [NaCl]. MC simulation results are also shown. e The plot of the average radius of inertia <Rg> vs. [NaCl] for clusters obtained by neutron scattering.
