Symposium CH02-Advances in In Situ TEM Characterization of Dynamic Processes in Materials

In situ transmission electron microscopy (TEM) techniques have emerged as primary tools for characterizing the dynamics of materials formation and transformations. The development of in situ TEM capabilities, such as heating, cooling, biasing, ion irradiation, and mechanical testing, has led to rapid advances in our understanding of crystallization, electrochemical processes, and structure-function relationships in organic, semiconductor, metals, and other systems. The symposium covers a broad range of topics including particle nucleation and growth, phase transformations, and interface dynamics with gases, liquids, and solids. This symposium aims to provide a platform for discussion to understand the physical and chemical processes governing the dynamic process of behavior under different external stimuli using in-situ TEM, as well as computer-aided image analysis and data processing, e.g. artificial intelligence (AI) algorithms.

Topics will include:

  • Nucleation and crystal growth from solutions, melts, and vapors
  • Chemical and electrochemical reactions
  • Particle self-assembly processes
  • Phase transformation and dynamic process using heating, cooling, ion irradiation, mechanical testing
  • Advancement in specialized holders and electron microscopes and practical challenges for in-situ microscopy of phase (trans)formation and chemical reactions (including corrosion)
  • Integration of big data-driven image analysis (machine learning and AI) with in-situ TEM for quantitative studies
  • Interface-driven processes and interface dynamics in gases and liquids
  • Mechanically, electrically, or magnetically driven processes
  • A tutorial complementing this symposium is tentatively planned.
