Chaoying Ni

Chaoying Ni is a Professor and Director of the W. M. Keck Center for Advanced Microscopy and Microanalysis at the University of Delaware's Department of Materials Science and Engineering. His research focuses on advanced microscopy techniques (e.g., TEM, SEM) and their applications in analyzing novel structures and composites. Key areas include in-situ & low-dose electron microscopy, nanomaterials for environmental/energy applications, multifunctional composites, and pharmaceutical materials' crystal polymorphism.

Dr. Ni’s work explores process-structure-property relationships in advanced materials, such as mesoporous crystals, nanostructures, and thin films. He leads efforts in developing cutting-edge equipment for in-situ mechanical/electrochemical testing and cryo-microscopy. His group investigates phenomena like phase transformations in responsive materials and catalytic systems (e.g., Pd/Si-thiol for Suzuki coupling reactions).

Recent articles span nanomaterials for drug delivery, photocatalytic systems, and magnetic alloys, reflecting his interdisciplinary approach to materials science. His research bridges fundamental microscopy advancements with practical applications in energy, environment, and health.

Labs/Teams: Directs the Keck Center and collaborates with the Harker ISE Laboratory. Research group focuses on microscopy, nanotechnology, and composite materials.
