I'm Prof. Chia-Che Chang. My research focuses on the synthesis and functional design of nanomaterials for catalytic applications, with in-situ characterization. I have conducted synchrotron-based experiments at the National Synchrotron Radiation Research Center (NSRRC), utilizing advanced in situ X-ray techniques to probe dynamic structural and electronic changes in nanomaterials under working conditions.

Our laboratory focuses on the rational design of nanomaterials for catalytic antibacterial applications with an emphasis on reactive oxygen species (ROS) generation. By engineering nanomaterials catalysts with optimized surface chemistry and electronic structures, forward to enhance the efficient production of ROS, such as •OH, O₂⁻, and ¹O₂, which induce oxidative damage to bacterial membranes, proteins, and nucleic acids.
