Doped Nickelate Enters a New Phase with Spintronics Potential
Rare-earth nickelates are known to undergo a metal-to-insulator phase transition as temperature decreases, the mechanism of which is not well understood. Here, researchers observed a new low-temperature phase that’s both metallic and antiferromagnetic—an unusual combination with potential value in spintronics. Read more »
Dimitri Argyriou Named Next ALS Director
Dimitri Argyriou, an accomplished physicist and Associate Director for In-Kind Management at the European Spallation Source, has been selected to serve as the next director of the Advanced Light Source. His appointment is expected to begin this June. The announcement follows an international search. Read more »
Imaging Topological Magnetic Monopoles in 3D
Researchers created topologically stable magnetic monopoles and imaged them in 3D with unprecedented spatial resolution using a technique developed at the ALS. The work enables the study of magnetic monopole behavior for both fundamental interest and potential use in information storage and transport applications. Read more »
In Situ and Operando Characterizations of Metal Halide Perovskite and Solar Cells: Insights from Lab-Sized Devices to Upscaling Processes
The performance and stability of metal halide perovskite solar cells strongly depend on precursor materials and deposition methods adopted during the perovskite layer preparation. This review presents an update of studies conducted in situ using a wide range of structural, imaging, and spectroscopic techniques, involving the formation/degradation of halide perovskites.

Chatbot-Style AI Designs Novel Functional Protein
Researchers used an artificial intelligence (AI) algorithm, similar to those used in natural-language (“chatbot”) models, to design a functional protein that was then structurally validated at the ALS. The work could speed the development of novel proteins for almost anything from therapeutics to degrading plastic. Read more »
Intrinsically Chiral Twist-Bend Nematogens: Interplay of Molecular and Structural Chirality in the NTB Phase
Cartoon depiction of the formation of the heliconical chiral twist-bend nematic phase (N*TB) from its constituent bent molecules. The presence of a single enantiomer of the chiral, lactate-based liquid crystal dimers biases the formation of helices with only one handedness, unlike in the conventional NTB phase, observed for achiral molecules, for which the left- and right-handed helices are doubly degenerate.

Electric Vehicle Batteries Could Get Big Boost With New Polymer Coating
Scientists have developed a conductive polymer coating—called HOS-PFM—that conducts both electrons and ions at the same time. This ensures battery stability and high charge/discharge rates while enhancing battery life. The coating also shows promise as a battery adhesive that could extend the lifetime of a lithium-ion battery from an average of 10 years to about 15 years. Read more »
Shaping X-Ray Mirrors Using Machine Learning
Researchers used machine learning to predict and control the shape of an x-ray mirror’s surface with exquisite accuracy and precision. The work represents a key step toward mirrors that can fully exploit the x-rays from upgraded, state-of-the-art light sources and could also enable the engineering of x-ray beams with novel characteristics.
