Real-space tilting method for atomic resolution STEM imaging of nanocrystalline materials
Jiake Wei, Zhangze Xu, Wenjie Shen +5
Atomic-resolution scanning transmission electron microscopy (STEM) characterization requires precise tilting of the specimen to high symmetric zone axis, which is usually processed…
Surface step induced bending in two-dimensional oxide nanosheet
Jiake Wei, Masato Yoshiya, Feng Bin +2
The surface steps play dramatic roles in surface dominated processes and the related properties, in which these roles would be significantly enhanced for the low-dimensional nano o…
The Lightest 2D Nanomaterial: Freestanding Ultrathin Li Nanosheets by in-situ Electron Microscopy
Muhua Sun, Nore Stolte, Jianlin Wang +7
Lithium (Li) is the simplest metal and the lightest solid element. Here we report the first demonstration of controlled growth of two-dimensional (2D) ultrathin Li nanosheets with…
Electrochemical solid-state amorphization in the immiscible Cu-Li system: Size matters
Muhua Sun, Jiake Wei, Zhi Xu +4
As a typical immiscible binary system, copper (Cu) and lithium (Li) show no alloying and chemical intermixing under normal circumstances. A notable example that takes advantages of…
