Kinetic Regimes of Hydrogen Absorption in Thin Films
Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials
Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...
