Representative HREM images of selected samples. (a,b) Sample annealed 5 and 10 min. showing an oval nanoparticle (few tens of nm) with lattice fringes spacing of ∼6.6 Å (insets) consistent with the (110) plane of augite. Other nanoparticles, non-suitably oriented for lattice fringe imaging, are visible all around, in particular at the lower side. (a) Moiré fringes (arrow) arising from the superposition of crystalline nanoparticles. (c) The particle at the center-right of the image is augite oriented along [1–1 0] that shows two sets of lattice fringes intersecting at ∼80° with spacing at ∼6.6 and ∼5.1 Å. (d) Magnification of the white box* in (c) showing the augite (110) lattice fringes.
