STEM images of LTO-RT-600: (a, b) HAADF and (c) corresponding ABF images

                           of LTO-RT-600 NSs. The simulated HAADF images of (d) LTO projected from [110]

                           direction and (e) rutile-TiO2 projected from [100] direction. The insets show the

                            arrangements of atoms. (J. Am. Chem. Soc., 2012, 134, 7874-7879)
