NMR Study of Effects and Mechanisms of Mechanical Activation on Hydrogen Sorption/Desorption of Nanoscale Lithium Nitrides
EMSL Project ID
13499b
Abstract
Recently our proposal on "Effects and Mechanisms of Mechanical Activation on Hydrogen Sorption/Desorption of Nanoscale Lithium Nitrides" has won DOE-EE?s "Grand Challenge" Award for Basic and Applied Research in Hydrogen Storage. The funded proposal was a collaborated effort between the University of Connecticut and PNNL. While focusing on developing novel nanostructured hydrogen storage materials, PNNL is also responsible for studying the mechanically activated, nanostructural lithium nitride base materials using NMR spectroscopy that is available at PNNL. Preliminary work carried out under previous user proposal proved that the NMR techniques is a suitable, sensitive tool to gain insight into the material structure and local chemistry, providing vital information for sustained materials development and optimization. This User Proposal is, therefore, a direct support to a funded DOE project.
