Scheme of the experimental setup and of the experimental conditions in which the self-assembly was investigated. (a) Representative TEM image of FeO/CoFe₂O₄ NCs used in these measurements. (b) Emulsion, while heated and stirred in a vial in order to evaporate the nonpolar phase, is pumped through a capillary using a peristaltic pump. The emulsion is then probed, while in the capillary, by X-rays. The experiment has been performed three times with the SAXS detector at three different distances, 1, 5, and 30 m, in order to probe the full q range: from the region where the NCs scatter up to the region where the droplets and, later, the SPs scatter. (c) Representative SE-STEM image of a SP made of FeO/CoFe₂O₄ NCs as obtained from this experiment.
