Professor of Physics Stephen FitzGerald in spring 2017 was awarded a three-year, $310,000 grant from the National Science Foundation to support his project entitled "RUI: Probing adsorbate interactions in metal-organic frameworks using site selective spectroscopy."

This research examines hydrogen storage for fuel-cell applications and isotope separation for chemical labeling, medical tracing, and heavy water moderators. The grant provides funds for on-going student participation and the acquisition of a specialized mass-spectrometer.
