Ultra-Small Fatty Acid-Stabilized Magnetite Nanocolloids Synthesized by In Situ Hydrolytic Precipitation

Figure 4

TEM images of the different sized OA-stabilized M³NPs of iron oxide prepared by varying the ratios of OA to the iron precursor. (a) No OA (0 mmol OA), (b) 1x (1.5 mmol OA), (c) 3x (4.5 mmol OA), (d) 5x (7.5 mmol OA), and (e) 10x (15 mmol OA). (f) Summary of the morphological and size variations of OA-stabilized M³NPs with increasing OA to iron precursor ratios (0, 1, 3, 5, and 10).
