Controlling Structure and Stability in Ultrathin Ti3C2Tx MXene Multilayers for Hydrogen Gas Barrier Applications

Advanced Functional Materials, EarlyView.
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−

Low‐Flicker‐Noise MoS2 Transistors Enabled by High‐κ Rare‐Earth Oxychlorides for Mixed‐Signal Electronics

Advanced Functional Materials, EarlyView.
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.

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

Advanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.
