Advanced Energy Materials, Volume 16, Issue 19, 20 May 2026.This review focuses on operando studies of battery materials by X‐ray diffraction (XRD) and total X‐ray scattering (TXS). This work highlights potential pitfalls and identify best‐practices for operando studies and reviews some unusual experiments to illustrate how these methods can be applied beyond the evaluation of the early‐stage cycling mechanisms

Nonlinear Electrodynamics in Magnetars: Systematic Effects on Radius Constraints and Timing Analysis
The Astrophysical JournalMagnetars are among the most extreme laboratories in the Universe, harboring surface magnetic fields reaching 10 ^15 G. At these supercritical scales, Maxwell’s linear electrodynamics is superseded by nonlinear electrodynamics (NLED).

The Astrophysical JournalIt was previously believed that the long-term persistent increase in the spin-down rate of the Crab pulsar following a glitch is direct evidence of a starquake-induced glitch or at least related to a starquake.

Braking index of the frequently glitching PSR J0537−6910★
Astronomy & AstrophysicsContext. The pulsar J0537−6910 undergoes spin-up glitches more frequently than any other known pulsar, at a rate of roughly thrice per year. Its glitches are typically large and accompanied by abrupt changes in the spin-down rate ( ν˙ ν ˙ $ \dot{\nu}

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Long-term Timing Evolution of Four Anomalous X-Ray Pulsars
The Astrophysical JournalAnomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are believed to be manifestations of magnetars. Typically, AXPs exhibit higher X-ray luminosities, whereas SGRs are generally fainter and display significantly high signal-to-noise ratios

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT A short X-ray burst was observed from the radio-loud magnetar 1E 1547.0–5408 in 2022 April. Unusually however, the source stopped showing radio pulsations $\gtrsim 3\,$ weeks prior to the burst. After recovery, radio timing revealed that the object had also undergone a modest glitch.

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.Mg‐based thermoelectrics are among the most promising candidates for power generation applications but their performance is compromised by Mg loss at device operation temperatures due to the higher chemical potential of Mg (μMg${\mu}_{\mathrm{Mg}}$) inside the material compared to the environment.
