Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals
Advanced Functional Materials, EarlyView.Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

Advanced Functional Materials, EarlyView.Multifunctional solid polymer electrolyte (SPE) films integrating intrinsic self‐healing, mechanical stretchability, and dual photo‐ and pH‐responsive ionic conductivity are developed. Constructed from thermoplastic polyurethane (TPU) and hydrogen‐bonded poly(thiourea triethylene glycol) (PTUEG3), these films form a dynamic supramolecular network ...

A New X-Ray and Radio Burst Activity from the Magnetar SGR 1935+2154
The Astrophysical Journal Supplement SeriesSGR 1935+2154 has emerged as the most active magnetar in recent years, exhibiting X-ray burst activity nearly annually and emitting a fast radio burst (FRB 200428 (FRB1)) in its 2020 April activity, for the first time from a Milky Way source, accompanied

Advanced Functional Materials, EarlyView.An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...

The Redshift Distribution of Einstein Probe Transients Supports Their Relation to Gamma-Ray Bursts
The Astrophysical Journal LettersThe 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 ...

Advanced Healthcare Materials, EarlyView.We introduce a new fabrication method that overcomes the current limitation of tubular gap electrospinning. We successfully fabricated a seamless hollow tube with fibers aligned along the longitudinal axis in diameters as small as 300 µm, and then reinforced it using 4‐axis 3D printing.

Fast X-Ray Transients in NuSTAR Data
The Astrophysical JournalFast X-ray transients (FXTs) are flashes of X-rays that last for a few hundreds of seconds to a few hours. An enigmatic population of these transients that did not have a clear origin has been known for several decades, mostly found serendipitously in ...
