Peng Wang
My research has been focused primarily on two areas:
- developing novel computational diffractive imaging techniques (ptychography, 4D STEM) for cryogenic electron microscopy (Cryo-EM), light atomic detecting (O, Li elements), low dose imaging (beam sensitive materials), 3D reconstruction and EM field mapping, which can then tackle characterization challenges across the physical and life sciences, ranging from battery materials to biological macromolecules;
- in situ examining atomic structures of advanced materials and their functional properties with an emphasis on complex oxides and two-dimensional materials.
To date, I have published over 100 refereed journal articles, including Nature, Science, PNAS, Nature Nanotechnology, Nature Electronics, Nature Catalysis, Nature Communications, Physical Review Letters, Advanced Materials and Ultramicroscopy.
Cryogenic electron ptychography (Cryo-EPty) is an emerging technique used for imaging the structure of biomacromolecules as demonstrated in our previous study (Nature Communications, 11, 2773 (2020)). Building upon that, recently, we have made it one step further by developing 3D single-particle analysis (SPA) based on cryo-EPty. It enables high-contrast with a wide spatial frequency band, potentially enhancing our ability to visualize biomacromolecular structures in 3D.
