Established in 2019, our research group is a relatively new group in the ICME, to fulfill the missions of the institute, especially “promoting research related to the basic science and application of the structure and functions of materials” by taking advantage of multi-scale & multi-dimensional materials characterization techniques. In particular, we focus on developing and utilizing advanced transmission electron microscopy, so-called “in-situ nanoimaging” to visualize＆investigate how materials response to external stimuli, i.e., heat, light, stress; such findings provide direct proof of underlying-mechanisms behind complex phenomena, and enhance understanding of macro-scale properties. Real-time nanoimaging demands hundreds or thousands of times faster data acquisition methods than conventional TEM imaging, which motivates us to strive novel methodology developments such as machine-learning-assisted image denoising for ultrafast 3D nanoimaging. Our unique imaging capabilities/expertise will unveil various physical/chemical phenomena at the nanoscale.
