High-Field Aluminum-27 NMR of Simulated Tank Waste Precipitates

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Karl Mueller
Project type
Capability Research
Our proposal is to use high-field NMR spectroscopy to resolve and quantify aluminum phases in simulated tank waste precipitate samples. It is known that clay minerals weather into zeolite-type phases…

High-Field MAS NMR of
Strontium-87 in Environmental Samples

Lead Institution
St. Mary's College of Maryland
Principal Investigator
Geoffrey Bowers
Project type
Capability Research
Our proposal is to use ultra-high-field MAS NMR spectroscopy to study strontium nuclei in solid samples. Strontium is a quadrupolar nucleus (I = 9/2) with a very low gyromagnetic ratio, large…

High-field Solid-State NMR Studies of Weathered Specimen Kaolinite Clays

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Karl Mueller
Project type
Capability Research
The dissolution or weathering of specimen kaolinite clay samples has been studied in our laboratory under geochemical conditions characteristic of those found in the vadose zone beneath leaking…
