Symposium TC02—In Situ Studies of Materials Transformations

In recent years, the in situ (S)TEM and synchrotron X-ray techniques have advanced tremendously by incorporating new environments, probes, and detectors, which provide the unprecedented promise to fulfill the emerging research needs in materials science. Materials discovery has inspired efforts to develop integrated approaches to complementarily probe the materials transformation including dynamical processes of materials synthesis, emergent phenomena and exotic physics of epitaxial heterostructures, and evolution of structures/properties of materials at different environments, for instance at extremely high/low temperatures and high pressures. For example, both in situ (S)TEM and synchrotron X-ray techniques (e.g., imaging, scattering, and spectroscopy) have been employed to study structural and chemical evolution of energy storage materials in real time and operation conditions. These in situ characterizations show spatial resolutions down to sub-nanometer scale. The combinational efforts of different in situ techniques have resulted in a paradigm shift for scientists in deeper understanding of the materials transformation mechanism. As a reward, the big data from the multimodal characterizations will certainly inspire the modeling and simulation which leads to the “materials by design”.

The symposium will cover a broad range of topics related to in situ studies of materials science. In particular, multimodal characterizations for in situ studies of materials transformation will be focused on. This includes the development and application of in situ techniques in the study of (but not limited to) materials phase transformations, crystal growth, electrochemical reactions, structural and chemical evolution in operando. The goal of this symposium is to bring together scientists and engineers to share the successes and the potentials for in situ multimodal observations to correlate with modeling and simulations across materials science disciplines.

Topics will include:

  • In situ imaging of phase transition (temperature, pressure, environmental)
  • High Pressure Materials Science and Chemistry
  • Real-time imaging of materials growth transformation
  • Real-time probing materials in catalysis process
  • Behavior of energy materials in chemical and electrochemical reactions
  • Mechanically, electrically or magnetically driven processes
  • Self-assembly of nanoparticles
  • Characterization of defects in materials (imaging and spectroscopy)
  • Electron beam/x-ray effects during in situ study
  • Novel in situ characterization techniques
  • In situ methods with theoretical modeling
