March 2019 Message from the UEC
Fanny Rodolakis, the chair of the Users’ Executive Committee (UEC) for 2019, reports on the most recent UEC meeting and calls for workshop and tutorial suggestions for this year’s User Meeting. Read more »
A New Twist in Soft X-Ray Beams
Visible-light beams with orbital angular momentum (OAM) have been used in applications ranging from communications and imaging to particle manipulation. Now, researchers have generated high-quality OAM beams in the soft x-ray regime, with intriguing possibilities for future use at high-coherence, diffraction-limited light sources. Read more »
Mechanical Competence and Bone Quality Develop During Skeletal Growth
Researchers explored how bone quality and mechanical competence progress during longitudinal bone growth. Deformation at the tissue, fibril, and mineral length scales was investigated with mechanical tensile tests during small and wide-angle x-ray scattering/diffraction (SAXS/WAXD) experiments, revealing dramatic differences in mechanical resistance with age.

Evidence of a Long-Predicted Magnet
Half a century ago, theorists proposed a novel way for materials to produce a magnetic field. Now, scientists have discovered a uranium compound that bears out that long-ago theory—a new type of magnet that holds promise for enhancing the performance of data storage technologies. Read more »
The Best Topological Conductor Yet: Spiraling Crystal Is the Key to Exotic Discovery
Researchers have discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure. The realization of so-called topological materials—which exhibit exotic, defect-resistant properties and are expected to have applications in electronics, optics, quantum computing, and other fields—has opened up a new realm in materials discovery.

Absorber Captures Excess Chemotherapy Drugs
Researchers have designed a biomedical device for absorbing excess chemotherapy drugs during cancer treatment, characterizing the active surface layer using x-ray microtomography. The work opens up a new route to fighting cancer that minimizes drug toxicity and enables personalized, targeted, high-dose chemotherapy. Read more »
Fingerprint Oxygen Redox Reactions in Batteries through High-Efficiency Mapping of Resonant Inelastic X-ray Scattering
We provide a comprehensive analysis and an explicit interpretation of the five evolving components of O-K mRIXS of the typical battery electrode that involves lattice oxygen redox reactions upon cycling. This work is the first benchmark for a complete assignment of all the important mRIXS features collected from battery materials, and thus delivers guidelines for future studies of oxygen redox reactions.

A Nanoscale View of Defect Effects on Band Structure
In the first comprehensive study at the ALS involving nanoARPES, researchers probed the electronic effects of defects in monolayer tungsten disulfide at the nanoscale. The extremely small scale of the measurements makes nanoARPES a great discovery tool that will be particularly useful for understanding new materials as they are invented. Read more »
