Symposium CH04-Advances in In Situ/Operando TEM Characterization of Dynamics and Functionalities in Materials

Recently, advanced in situ/operando electron microscopy techniques have extended the capability of investigating the structure, morphology, dynamics, and functionalities of materials across different length scales in their native environment with improved temporal and spatial resolution. For example, the motion of single Pt atoms in liquid could be visualized with a new design of liquid cell from 2D materials. Such real-time information also enriches statistics: Visualizing Brownian motion helps to map 3D lattice strain of a nanoparticle in liquid at single-atom resolution. Meanwhile, with new imaging modes and techniques integrated such as 4D-STEM and advanced detectors, emerging large data call for wise designs of data processing such as artificial intelligence algorithms, which in turn guides experiments and facilitates automatic in situ tools with “on-the-fly” data processing.

This symposium covers topics including crystallization and collective behaviors of nanomaterials, nanoscale heterogeneity and phase transformations, and processes with external stimuli. Additionally, works involving probing charge and heat transfer, lattice structure, and materials design based on insights from in situ strategies are welcomed. The symposium aims to pinpoint emerging directions in in situ/operando research in electron microscopy, X-ray techniques and spectroscopy, bridging mechanistic study, pragmatic synthesis, high output data processing, and above all, engineering of materials across various fields.

Topics will include:

  • Self-assembly pathways with in situ techniques
  • Nucleation and growth of crystals
  • Interfacial processes and dynamics in gases and liquids
  • Chemical and electrochemical reactions
  • Electrically, magnetically, thermally, or mechanically driven processes
  • Probing changes in structural, electronic and phononic properties
  • In situ 4D-STEM, ptychography, differential phase contrast imaging, and correlative imaging
  • Probing 3D information of complex systems
  • Image processing/big data mining (machine learning and AI) for in situ techniques
  • Material synthesis aided by in situ tools
