Fig. 5. Characterization of the magnetite crystals obtained by 0.5 vol% NH3 diffusion in 30 mL of 3 mM Fe solution in the (a and c) absence and (b and c) presence of 0.3 mg mL–1 M6A. (a) HRTEM image of a representative octahedral crystal. (b) TEM image of the rounded crystals aligned in strings. Inset: higher magnification. (c) Size distributions of the crystals obtained with and without M6A. Reproduced from ref. 83.
