Our Visions:

  • In-depth understanding of matter and energy at the nano/atomic level
  • Manipulating and creating materials atom(s) by atom(s)
  • Carbon builds the future technology

Research Interests

  • In situ electron microscopy and its applications to nanotechnology and methodology
  1. Developing new in situ TEM/SEM techniques to explore and tailor the electrical, mechanical, optical, thermal, and electrochemical properties of individual nanostructures.
  2. TEM-based additive, subtractive and equal material nano-manufacturing; Atomic Manufacturing.
  3. "Simulative" TEM characterization based on artifical strcutral models to reveal the evolution of battery materials in confined spaces.

 

 

 

 

 

 

 

We have two cutting-edge in situ characterization platforms based on TEM and SEM respectively, which allow for a comprehensive study of materials from structural visualization/analysis to property measurement/tailoring, and even nanoarchitecture creation.

 

 

  • Advanced energy storage materials and devices
  1. Design and fabrication of novel micro-nano materials for electrochemical energy storage
  2. Electrochemical energy storage devices (such as Li, Na, K-ion batteries, metal batteries, solid-state batteries, supercapacitors)
  3. Micro-device fabrication and test based on in-situ TEM/SEM techniques.
