The Guo Lab
Alexandra Navrotsky Institute for Experimental Thermodynamics
IN BRIEF
We are interested in the Structures and Thermodynamics of Nano, Bulk-Size Lanthanide and Actinide (Transuranium Actinide) Materials, for applications in nuclear fuel, nuclear waste form, and critical metal mineralization.
Our group has expertise in advanced structural and thermodynamic techniques:
- Thermal analysis and calorimetric techniques;
- X-ray/neutron scattering and X-ray absorption spectroscopy;
- High-pressure static compression techniques.
CURRENT RESEARCH TOPIC
- Actinide thermochemistry (transuranium labs for U, Th, Pu, etc.)
- Rare Earth Elements (REE) and actinide ceramics
- Geochemistry of REE and actinide (nano)minerals
- Molten salt thermochemistry (Calvet calorimetry on heat of mixing and heat capacity)
- Nuclear fuel research (U-N, U-Si, U-C, nanosized oxides, MOX)
- Nuclear ceramic-based wastes (silicates and phosphates)
- Materials under extremes (high-temperature, high-pressure, and hydrothermal conditions)
