[Chun's Research Group]
Our group works in imaging the way that crystals grow and the way that crystals evolve at the atomic level by using in-situ transmission electron microscopy. If we can image materials that are under the working conditions, we are more likely to understand underlying principle behind the reaction. And if we can understand the reaction principle, we can have a chance to control the materials growth, further their crystal structures/orientations. Therefore, our research involves putting different materials in a transmission electron microscopy, and imaging their changes under the heating, gas and liquid environments. We have focusing on imaging of energy materials for hydrogen storage and catalyst. And one interest area that we are especially excited about is discovery “new metastable phase” by liquid cell TEM.
