  • Directly observing the continuous development of microstructures in dynamic experiments
  • Choice of thin foil specimens, with diffraction and atomic resolution imaging, in TEM; or larger samples and greater flexibility, but lower resolution, in SEM
  • Temperature range from below-170C to >1000C
  • Controlled gas environments for catalysts, oxidation, reduction, processing and surface effects
  • Specialized facilities for heating, cooling, straining, environment, magnetization, electrical potential and current
  • Influence of the electron beam and how to minimize the impact
  • Practical experimental methods, data recording and analysis, and the design of reliable experiments
  • Future developments

There are many obvious advantages of in situ observations at the microscopic level. Most notably, there is simply no substitute for observing material behavior as it occurs, both directly and continuously. In the proper experiments, speculation on the sequence of events is unnecessary, and important steps in a reaction are not overlooked. The major challenges then are to design the procedure and the hardware to reveal the most important information (preferably in a quantitative manner) and to ensure that the experimental circumstances warrant the conclusions that are drawn (i.e., to avoid artifacts).

This tutorial will emphasize the methodology and procedures which are required to ensure reproducible and interpretable data from dynamic observations. The wide range of applications will be illustrated by focusing on several separate techniques. In transmission electron microscopy, microstructural and crystallographic information is provided by the combination of imaging and diffraction, even at the lattice resolution level. This can be obtained under heating and cooling conditions, specimen straining, application of electrical potential and current, varying magnetic fields, etc. It is essential here to overcome the limitations of the thin-foil specimen and the microscope environment (including possible influence of the imaging beam). Extension of these techniques to varying environments (environmental microscopy) ranging from moderate gas
pressures (e.g., low mbar) to ultra-high vacuum conditions allows insight into catalyst behavior, oxidation and reduction, and surface effects. The scanning electron microscope offers even
greater potential for in situ studies, because of the larger space around the sample combined with the depth of field of the imaging conditions, but at the expense of resolution, crystallographic and often microstructural information. In all cases, efforts to ensure "proper experiments" will be
discussed.
