Our efforts to introduce defects in rutile by conventional mechanical grinding as used for TEM study did not produce any defects or twinning. Experimental SAED patterns of rutile with intercalated
-PbO2-type TiO2 lamellae are consistent with those expected from calculated patterns. The values and precision of lattice parameters of
-PbO2-type TiO2 derived from such SAED patterns are also consistent with crystal data from X-ray diffraction studies.
