Figure 1. Temperature profile of the temperature-paused single-step thermal decomposition synthesis.

Boxes sketch the expected predominant structures for each time zone. Typically, both waiting times are 120 minutes. Images: TEM images of BLNs obtained following the temperature-paused single-step protocol. Ag corresponds to the dark contrast, while lighter particles correspond to magnetite. Plain magnetite nanoparticles which are formed are also shown in c). a) b) and d) are different amplifications of BLNs in order to understand the structure.
