Researchers tracked the movement of the platinum nanoparticles that catalyze reactions in polymer electrolyte fuel cells (PEFCs) and correlated this movement with nanoparticle degradation. The results yielded solutions that can immediately reduce platinum waste in emission-free heavy-duty fuel-cell vehicles. Read more »

Computer-Aided Protein Design for New Biomaterials
Using a computer-based approach, researchers designed porous protein crystals that were revealed to be stable, tunable, and atomically accurate using x-ray scattering and diffraction at the ALS. The work provides a powerful new platform for biological materials engineering and opens up wide applications in biotechnology and medicine. Read more »
“Computer Vision” Review of X-Ray Movies Leads to New Insights
Using a type of machine learning called “computer vision” to mine data from x-ray movies, researchers made new discoveries about the reactivity of a material in rechargeable batteries. The results suggest that optimizing the carbon layer thickness on the electrode surface could help researchers to design more efficient batteries. Read more »

Building a Two-Dimensional Magnet One Atom at a Time
Researchers synthesized a new two-dimensional ferromagnet and measured how its electronic and magnetic properties evolve with increasing thickness and temperature. Such atomically thin magnetic materials with tunable magnetic properties would be very useful in next-generation microelectronic and spintronic applications. Read more »
Optical Properties of Individual Tar Balls in the Free Troposphere
Tar balls are found in biomass-burning smoke, and their sunlight-absorption properties are highly uncertain. This study investigates the optical properties of individual tar balls in the free troposphere to better understand their influence on climate. Read more »
Why Do Batteries Sometimes Catch Fire and Explode?
In order to better understand how a resting battery might undergo thermal runaway after fast charging, scientists are using a technique called “operando x-ray microtomography” to measure changes in the state of charge at the particle level inside a lithium-ion battery after it’s been charged.
