Winner of the 2015 Journal of Materials Research Paper of the Year Award Announced
Dr. Chong-Min Wang, Chief Scientist at Pacific Northwest National Laboratory and a leading expert in atomic-level characterization/visualization of materials structure using electron microscopy and spectroscopy, is the winner of the Journal of Materials Research (JMR) 2015 Paper of the Year Award for his paper, “In situ transmission electron microscopy and spectroscopy studies of rechargeable batteries under dynamic operating conditions: A retrospective and perspective view” JMR 30 (3) 3 (2015).
Since the advent of the transmission electron microscope (TEM), continuing efforts have been made to image material under native and reaction environments that typically involve liquids, gases, and external stimuli. With the advances of aberration-corrected TEM for improving the imaging resolution, significant methodologies have been developed that allow imaging under dynamic operating conditions, or in situ TEM imaging. The success of in situ TEM imaging is closely associated with advances in microfabrication techniques that enable manipulation of nanoscale objects around the objective lens of the TEM. This study summarizes and highlights recent progress involving in situ TEM studies of energy storage materials, especially rechargeable batteries. The type of tools described in Wang’s paper are ground-breaking as they will enable researchers across the entire spectrum of materials research to probe and understand material behavior and performance based on direct observation during operation.
