Research

Dr. Xiaofeng Guo received his Ph.D. in Chemistry from the University of California, Davis in 2014 under the supervision of Professor Alexandra Navrotsky. He continued the postdoctoral research with Dr. Hongwu Xu at the Los Alamos National Laboratory as a Seaborg Postdoctoral Fellow.
He joined WSU in 2018, received the NSF CAREER award in 2022, and Early-Career and Emerging Researchers in Physical Chemistry (JPCC) in 2023.

The focus of his research is studying the structures and thermodynamics of f-block condensed matter.
In Guo’s lab, we study lanthanides and actinides containing materials and minerals by probing their structural changes and energetic landscapes under (extreme) conditions, via synchrotron X-ray and neutron scattering, X-ray spectroscopy, ultrasonic spectroscopy, data-driven analysis, and advanced calorimetry.

We are interested in the following research areas:

• Actinide thermochemistry (transuranium labs for U, Th, Pu, etc.)
• Rare Earth Elements (REE) and actinide ceramics
• Geochemistry of REE and actinide (nano)minerals
• Materials under extremes (high-temperature, high-pressure, and hydrothermal conditions)
• Molten salt thermochemistry (Calvet calorimetry on heat of mixing and heat capacity)
• Nuclear fuel research (nanosized oxides, MOX, U-Si, U-C, U-N fuels)
• Nuclear ceramic-based wastes (silicates and phosphates)

Students in the group will be trained in inorganic synthesis; X-ray and neutron-based characterizations (X-ray and neutron scattering, PDF, XAS, XRF); high pressure (diamond anvil cell); ultrasonic resonant spectroscopy, and thermal analysis techniques (DSC, TGA, high temperature calorimetry).
