Investigations of Electric Field Gradients and NMR Chemical Shifts of 87Sr in Mixed Calcium/Strontium Systems Using High Field NMR and Computational Chemistry

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Karl Mueller

Project type

Large-Scale EMSL Research

Calcium (Ca) and strontium (Sr) both form divalent ions that share rich and important chemistries. In light of the importance of Sr for the DOE mission, we are studying the substitution of Sr into…

The Chemistry of Hanford Sediments Reacted with Simulated Tank Waste Leachates: High-Resolution 27Al MAS and MQMAS NMR Studies

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Karl Mueller

Project type

Large-Scale EMSL Research

At sites such as Hanford, a former US Department of Energy (DOE) plutonium production facility, caustic nuclear waste (containing Cs-137 and Sr-90) has leaked from underground waste storage tanks…

Quantifying the Reactive Surface Area of Environmental Materials

Lead Institution

University of California, Merced

Principal Investigator

Peggy O'Day

Project type

Large-Scale EMSL Research

A large number of natural and anthropogenic processes in our environment are dominated by chemical reactions at the interface between solid and aqueous phases. These reactions include the adsorption…
