Electron tomography analysis of Ni@SiXNS-EtOH. a A screenshot image depicting the volume rendering of the 3D reconstruction and b–e images of slices obtained at different z depths of the 3D reconstruction of a particulate of Ni@SiXNS-EtOH. Slices shown in b and e reveal almost no Ni-containing nanoparticles on the top and bottom of the composite particulate, whereas those shown in c, d reveal the presence of Ni-containing nanoparticles in the interlayer spaces between SiXNS. Tiny, scattered white dots in the background of a are the added gold nanoparticles as track markers
