300 MHz NMR Mazama (Solids)
Highlighted Research Applications
- Characterization of natural and soil organic matter (NOM and SOM)
- CO2 sequestration investigations via high-pressure MAS
- Amorphous material characterization (e.g. glass).
Researchers may operate the system independently and can be trained to manage fully self-directed operations. Collaborative work with staff scientists is encouraged.
