December 2017: User Proposals Accepted for Beamlines at SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory

User proposals were submitted and accepted for beamlines at both the Stanford Synchrotron Radiation Lightsource (SSRL) at SLAC National Accelerator Laboratory and the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory. The hard X-rays at SSRL permit the analysis of potential storage materials in situ under high hydrogen pressures using techniques such as X-ray Raman scattering (XRS) and transmission X-ray microscopy (TXM). The soft X-rays allotted at BL 11.0.2 for Ambient Pressure X-ray Photoelectron Spectroscopy (AP-XPS) can be employed in the study of the chemical states of desorbing hydrides in operando.

December 2017: HyMARC Investigating Hydrogen Interaction with Materials

Hydrogen gas (white) interacts with the hydrogen storage material magnesium diboride (green and blue) at exposed edges to produce BxHy intermediate species. HyMARC is investigating mechanisms of hydrogen interaction with materials by combining modeling and simulation with spectroscopy and other experimental probes.

December 2017: Nanoconfinement Offers Advantages for Solid-State Hydrogen Storage Media

Schematic of the core-shell microstructure of lithium nitride nanoparticles confined in a carbon matrix during hydrogenation. The outer shell (white and red) is lithium amide, whereas the inner shell (yellow and red) is lithium nitride. Nanoconfinement offers potential thermodynamic and kinetic advantages for solid-state hydrogen storage media based on complex metal hydrides.

May 2016: “Approved Program” granted for Advanced Light Source (ALS).

Dedicated beam time for three years was granted for HyMARC-related experiments at the ALS, located at Lawrence Berkeley National Laboratory. The end stations accessed are and 7.3.1 for Scanning Transmission X-ray Microscopy, and 6.3.1 for X-ray Absorption Spectroscopy. The soft X-rays produced at the ALS are ideal for probing metal hydrides and sorbents composed of light elements (B – Al), as well as first-row transition metals. These resources will be employed by HyMARC researchers to probe the bonding environment surrounding these atoms and to image nanoscale buried interfaces that form when metal hydrides decompose.
