Dr. Xiaofeng Guo received his B.S. in Physics from Sun Yat-sen University in 2010 and completed his Ph.D. in Chemistry from the University of California, Davis in 2014 under the supervision of Professor Alexandra Navrotsky. Later he continued the postdoctoral research with Dr. Hongwu Xu at the Los Alamos National Laboratory from 2015 to 2017 as a Seaborg Postdoctoral Fellow. He joined the Chemistry Department of WSU in 2017 and will permanently relocate to Pullman in 2018.

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. The research topics include:

  • Thermochemistry of nano-materials, ceramics, minerals, metals/alloys, molten salts, and low dimensional materials
  • 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 high pressure
  • 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, electron, and neutron-based characterizations (X-ray and neutron scattering, XAS, XPS, SEM, PDF); high pressure (diamond anvil cell) and thermal analysis techniques (DSC, TG, high-T calorimetry).
