Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

The Redshift Distribution of Einstein Probe Transients Supports Their Relation to Gamma-Ray Bursts

The Astrophysical Journal Letters
The launch of the Einstein Probe unleashed a new era of high-energy transient discovery in the largely unexplored soft X-ray band. The Einstein Probe has detected a significant number of fast X-ray transients that display no gamma-ray emission ...

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

On the Ultralong Gamma-Ray Transient GRB 250702B/EP 250702a

The Astrophysical Journal Letters
GRB 250702B/EP 250702a is an interesting long-duration gamma-ray transient whose nature is in debate. To obtain a full picture in the gamma-ray band, we implement a comprehensive targeted search of burst emission in a wide window of 30 days jointly with ...

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
