The Cover schematically illustrates the effects of the catalytic gaseous environment on image formation during in situ environmental scanning transmission electron microscopy (ESTEM).In their Full Paper, Y. Zhu and N. D. Browning present the first evaluation of the sensitivity and resolution of STEM imaging mode with the presence of gases. It was found that ESTEM offers superior signal‐to‐noise ratio and predictable resolution in imaging solid catalysts under realistic reaction conditions. This work would serve as a basis for an advanced environmental imaging method that opens up new opportunities for in situ investigation of catalytic dynamics at the atomic scale. More information can be found in the Full Paper by Y. Zhu and N. D. Browning on page 3478 in Issue18, 2017 (DOI: 10.1002/cctc.201700474).
