Fig. 1. (a) Bright field image of an LSF grain after reduction in dry H2 at 873 K (1 h, 1 mL s−1), showing the exsolved Fe particles decorating the surface. A high-resolution image is shown in (b), with the respective FFT shown as inset. (c) HAADF image. (d–g) Individual EDX maps of Fe–K, O–K, Sr–K and La–L. (h) EDX line profiles across one particle along the arrow shown in the HAADF image shown in (c).
