Perpendicular magnetic anisotropy (PMA)—where magnetic moments in a thin film preferentially point out of the plane of the film—is an emergent phenomenon of both fundamental and technological interest. A combination of x-ray techniques demonstrate how to tune PMA in transition-metal oxide multilayers. Read more »

Dmitriy Voronov Receives Klaus Halbach Award
The 2017 Klaus Halbach Award for Innovative Instrumentation at the ALS was recently awarded to ALS Staff Scientist Dmitriy Voronov “for pioneering work in the area of advanced x-ray gratings.” The research that led up to Voronov’s award began about 10 years ago when he started at the ALS in the Experimental Systems Group with Howard Padmore.

Revealing the Blue Phase and Other Twisted Orders
Resonant soft x-ray scattering revealed liquid crystal structures that cannot be probed using diffraction, including chiral liquid crystal systems such as the “blue phase” and the twist-bend nematic phase. Information on how individual molecules form functional structures in these systems is key to developing new applications. Read more »
Sol Omolayo, Vacuum Systems Engineering Lead
Sol Omolayo joined the ALS about a year ago and has been enjoying the challenge of being part of the design team for the ALS Upgrade project, ALS-U, as well as applying his vacuum engineering expertise to current ALS operations. Read more »
New Catalyst Gives Artificial Photosynthesis a Big Boost
Researchers have created a new catalyst that brings them one step closer to artificial photosynthesis — a system that would use renewable energy to convert carbon dioxide (CO2) into stored chemical energy. Read more »
Watching a Quantum Material Lose Its Stripes
In the world of microscopic physics, periodic stripe patterns can be formed by electrons within so-called quantum materials. Scientists have now disentangled the intriguing dynamics of how such atomic-scale stripes melt and form, providing fundamental insights that could be useful in the development of novel energy materials.

Coral Exoskeleton Growth Begins Inside Living Tissue
Researchers have discovered some good news regarding corals: the mechanism by which their exoskeletons grow may help them resist the effects of ocean acidification. The discovery, made with PEEM studies, has ramifications not only for the health of coral reefs, but for applications such as 3D printing as well. Read more »
X-Rays Reveal the Biting Truth About Parrotfish Teeth
A parrotfish’s hardy teeth allow it to chomp on coral all day long, ultimately grinding it up through digestion into fine sand. Researchers wanting to see how the fine crystal structure of parrotfish teeth contribute to their incredible strength were able to visualize the orientation of individual crystals, which showed their intricately woven structure.

Natalie Larson Awarded Neville Smith Student Poster Prize
Natalie Larson, a current ALS doctoral fellow from UC Santa Barbara, won the first prize Neville B. Smith Student Poster Award at the 2017 ALS User Meeting. Larson’s winning poster featured the first two big in situ experiments she performed at Beamline 8.3.2. Read more »
Fuel Cell X-Ray Study Details Effects of Temperature and Moisture on Performance
A specialized type of hydrogen fuel cell requires precise temperature and moisture controls to be at its best. But seeing inside a working fuel cell at the tiny scales relevant to a fuel cell’s chemistry and physics is challenging, so scientists used x-ray-based imaging techniques to study their inner workings.
