Prof. Paul Voyles and researchers at the University of Wisconsin Madison in the USA have published the first results acquired using a Celeritas XS detector in Ultramicroscopy.
They took advantage of the detector’s rapid acquisition speed and sensitivity to use 4D STEM to map large areas of metallic glasses at nanometer-scale spatial resolution based on local rotational symmetry in diffraction patterns.

Abstract submissions are now open for the 2027 MRS Spring Meeting & Exhibit, including Symposium CH02: Advanced Electron Imaging, Diffraction and Spectroscopy Applied to Structurally Complex Materials. Direct Electron Applications Scientist Dr. Barnaby Levin is co-organizing Symposium CH02 at the 2027 MRS Spring Meeting & Exhibit, taking place April 5–9, 2027, in Seattle, Washington. The symposium will bring together researchers using advanced electron imaging, diffraction, and spectroscopy to investigate the relationships between structure and properties in complex materials. The program will span applications in electronic technologies, biomedicine, quantum materials, and other areas where understanding material structure across multiple length scales is critical. Particular emphasis will be placed on materials and structures that present challenging characterization problems, including disordered and amorphous materials, biomaterials, defective and strained crystals, grain boundaries and heterostructures, electric and magnetic structures, and materials with complex three-dimensional morphology. The symposium will also explore dynamic structural transformations, including changes driven by temperature, irradiation, electrochemical cycling, mechanical stress, and liquid or gas environments. Symposium Topics Topics of interest include: Disordered and amorphous materials Defective and strained materials Biomaterials Electric and magnetic structures in materials Characterization of 3D material structure Structural transformations with temperature change Structural transformations under irradiation Structural transformations in liquid and gas environments Grain boundaries and heterostructures Quantum materials Symposium Organizers Dr. Levin is organizing the symposium alongside Quentin Ramasse, SuperSTEM; Kayla Nguyen, University of Oregon; and Raymond Unocic, North Carolina State University. Share Your Research at MRS 2027 Researchers working with advanced electron microscopy techniques for structurally complex materials are encouraged to submit their work and join the discussion in Seattle.
