Figure 2

HRTEM images of Oleylamine–Acetone aged sample recorded at different dilutions. The solvent Acetone volume was kept to be constant as 5 ml and to which different volumes of aged sample (20 μl, 100 μl, 200 μl and 500 μl) was added to produce different levels of dilutions. (A) is the image from 20 μl diluted sample, (C) 100 μl diluted sample, (E) 200 μl diluted sample at the scale bar of 200 nm. (B,D,F) are higher magnification images at the scale bar of 20 nm. Aging assisted formation of nanoscale molecular (Oleylamine–Acetone) cluster can be visualized in the 20 μl diluted sample. (G) Schematic illustration denoting the self-assembly and Disassembly of flower-like aggregates in the concentrated and diluted states respectively.
