Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor
Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

An ultrathin nanocomposite MXene‐based multilayer effectively blocks hydrogen permeation by presenting a tortuous, layered structure. When the MXene is layered with reduced graphene oxide modified with a polycation, the resulting nanocomposite retains its hydrogen gas barrier properties at temperatures as high as 400°C (permeability of 7.13 ± 0.09 × 10−

Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Single‐crystalline LaOCl and GdOCl form atomically abrupt, Cl‐terminated interfaces with MoS2, enabling near‐ideal switching and suppressed flicker noise. Carrier‐number‐fluctuation analysis yields effective noise‐derived interface trap densities of 1.15–1.94 × 1010 cm−2 eV−1, approaching hexagonal boron nitride levels with high‐κ coupling.

This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Ultra‐Thin Tow‐Based Discontinuous Composites—Material Overview and Aspirations
Tow‐based discontinuous composites made from ultra‐thin tapes offer outstanding in‐plane mechanical properties. This material, inspired by Nacre, has high volume fraction of tapes exceeding 90 % and allows for quasi‐isotropic material plates less than 100 micrometer in thickness.

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts
The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...
