Chiral Phonon–Driven Ultrafast Spin Currents in a Non‐Magnetic Ferroelectric
Advanced Materials, EarlyView.Broadband terahertz emission spectroscopy shows signatures of ultrafast spin‐current generation in non‐magnetic ferroelectric β$\beta$’‐In2Se3${\rm In}_2{\rm Se}_3$. Reversal of the emitted field upon sample inversion and substitution of Pt with W indicates spin‐Hall‐mediated charge conversion, while polarization‐resolved measurements reveal ...

EP240414a: A Gamma-Ray Burst Jet Weakened by an Extended Circumstellar Material
The Astrophysical Journal LettersThe recent Einstein Probe (EP) event EP240414a exhibits several unusual observational features. Its prompt and afterglow emissions place it between long gamma-ray bursts (LGRBs) and low-luminosity GRBs (LLGRBs).

Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching
Advanced Materials, EarlyView.By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Modeling the Imprints of Large-scale Magnetized Structures on γ-Rays from Extragalactic Transients
The Astrophysical JournalIn the multimessenger era, the association of high-energy transients with their γ -ray counterparts can be obscured by magnetized large-scale structure surrounding the source.

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials
Advanced Materials Interfaces, EarlyView.Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

Advanced Materials Interfaces, EarlyView.A dual‐modulus silicone release film creates distributed stress concentrations at high‐/low‐modulus boundaries, triggering multi‐site crack initiation and rapid interfacial detachment. The architecture lowers the peak separation force by 97.6%, shortens detachment time, and enables stable continuous projection stereolithography at 720 mm h−1, offering ...
