title: Atomic mechanism of predictable phase transition in dual-phase H2 Ti3 O7 /TiO2 (B) nanofiber: an in situ heating TEM investigation.
abstract: The phase transition from H(2)Ti(3)O(7) to TiO(2) (B) in a 1D single nanocrystal of H(2)Ti(3)O(7) was observed by in situ heating in a transmission electron microscope experimentally. The results indicate a typical monoclinic-to-monoclinic crystallographic orientation relationship between the two phases. Moreover, the fundamental building blocks and invariant deformation element model were both adopted to reveal the atomic mechanism and predict the crystallographic orientation relationship quantitatively for the phase transition. The prediction was precisely consistent with TEM results.
