We study a variety of physical and chemical processes of materials with a focus on materials transformations and dynamic phenomena at solid-liquid and solid-liquid-gas interfaces. Besides in-situ liquid and gas transmission electron microscopy (TEM), we use an array of complimentary approaches including X-ray, theoretical modelling, nanofabrication, data processing through machine learning and other TEM techniques (Cryo-EM, diffraction imaging, EELS, EDS, etc.) to tackle research challenges. By revealing of atomic-level materials transformations and nanoscale heterogeneity and fluctuations at solid-liquid interfaces, we unravel the atomistic mechanisms of growth, structural transformations and other dynamic phenomena of materials. A deeper understanding of these physical and chemical processes enables us to advance the design and fabrication of functional materials and address a broad range of materials problems, from materials synthesis to catalysis, batteries and corrosion protection.
Our lab is located at MSD LBNL (Building 62, Room 248 & 250; Building 66 Room 230 & 233), which houses the capability of materials synthesis, laser-solution synthesis, air-sensitive materials handling, electrochemical property measurements, TEM sample preparation and in-situ TEM. We also have access to the state-of-art facilities at LBNL and UC Berkeley.
