Dr. Xiaofeng Guo received his Ph.D. in Chemistry from the University of California, Davis in 2014 under the supervision of Professor Alexandra Navrotsky, and completed his B.S. in Physics from Sun Yat-sen University in 2010. Later he continued the postdoctoral research with Dr. Hongwu Xu at the Los Alamos National Laboratory as a Seaborg Postdoctoral Fellow.

The focus of his research is studying solid state chemistry and thermodynamics of lanthanides and actinides containing materials and minerals by probing their structural changes and energetic landscapes under (extreme) conditions, via synchrotron, neutron-based techniques, and advanced calorimetric instruments.

We are interested in the following research areas:

  • Thermochemistry of nano-materials, ceramics, minerals, metals/alloys, and molten salts
  • Structure and thermochemistry of lanthanide, actinide(transuranium)-containing materials and minerals
  • Nano-materials, composites related to nuclear applications and environmental concerns
  • In situ measurements of phase alterations and physical properties at combined temperature-pressure conditions
  • In situ probing the synthesis and speciation under hydrothermal conditions
  • Calorimetric instrumentation developments

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) and thermal analysis techniques (DSC, TGA, high-T calorimetry).
