The Guo Lab Alexandra Navrotsky Institute for Experimental Thermodynamics

The research in Guo Group integrates advanced structural and thermodynamic techniques to study synthetic and natural material systems with special focuses on actinides and transuranium-containing systems.

Our group has expertise in various thermal analysis and calorimetric techniques, high-pressure static compression techniques, and various material synthesis and characterization techniques, including neutron and synchrotron X-ray spectroscopies.


The currently available research topics are:

  • Molten salt chemistry and thermodynamics (Calvet calorimetry on heat capacity and ΔH_mix)
  • Nuclear fuel research (nanosized oxides, MOX, U-Si, U-C, U-N fuels)
  • Nuclear ceramic-based wastes (silicates and phosphates)
  • Thermochemistry and geochemistry of REE systems 
  • Thermodynamics of lanthanides, actinides-containing minerals 
  • Behaviors of materials under extremes (high-temperature, high-pressure, and hydrothermal conditions).




We are partnered with Wu Research Group in the Gene and Linda Voiland School of Chemical Engineering and Bioengineering, and Nuclear Science Center.
