LIGHT SCATTERING: CGS-3 LSE-5004 and LSE-5003 correlator
1. Self-assembly and stabilization of AgCl by mono-vacant [a-PW11O39]-7 in water, As revealed by
cryo-TEM compared to DLS analysis.
Fig. 1.(B): A histogram of particle-edge lengths from cryo-TEM images; median edge length = 29 ± 4 nm (mean deviation). Inset to panel B: DLS measurement of Rh. indicated an average hydrodynamic radius (Rh) of 20 nm, and a narrow Rh distribution of 17–24 nm.

2. The effects of POM structure and charge were systematically evaluated using a series of plenary and mono-defect cluster-anions.
Fig. 2: Rh values of AgCl solutions prepared using plenary Keggin anions (no vacant sites; blue squares), and mono-vacant ions (red circles). The open triangle (for [a-AlNiIIW11O39]7-) is described in the publication.

Fig. 4: DLS results for particles distribution of Gold-nano particles, which formed by green chemistry methods from lemon verbena planet extraction;
Right above- SEM results for the particles shows distribution size of 25±4nm roughly. (Research from Prof. Yehuda Zeiri's group, Biomedical Engineering Department, BGU)
