Project type

Large-Scale EMSL Research

Hanford vadose zone sediments (Hanford coarse, Hanford fine, and Ringold silt) have been weathered by reaction with a simulated Hanford tank waste leachate and examined with a wide array of…

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
