Congratulations to Jianwei (John) Miao for receiving the 2021 Innovation in Materials Characterization Award from the Materials Research Society for pioneering coherent diffractive imaging for a wide range of material systems and atomic electron tomography for determining atomic positions without assuming crystallinity.

Beyond Crystallography: Coherent Diffractive Imaging and Atomic Electron Tomography

Over the last century, crystallography has been fundamental to the development of many fields of science. However, many samples in materials science, physics, chemistry, nanoscience, geology, and biology are non-crystalline, and thus their 3D structures are not accessible by crystallography. Miao will present two methods that can go beyond crystallography: coherent diffractive imaging and atomic electron tomography. He will illustrate the basic principle and broad application of coherent diffractive imaging. He will also present atomic electron tomography for 3D structure determination of crystal defects and amorphous materials at the single atomic level.
