Advanced Science, EarlyView.Transmission electron microscopy reveals that the formation of planar defects in Au–Pd–Pt–Ru CCSS thin films depends on Ru content, which in turn influences hydrogen evolution reaction electrocatalytic activity. As the Ru content increases, the density of nanotwins initially rises; with further Ru addition, stacking faults form.

Advanced Science, EarlyView.This study investigates the effects of thermal deposition rate on next‐generation p‐type amorphous oxide semiconductor SeTe–TeOx films. Deposition rate governs the chemical states, microstructure, and electrical characteristics of the films, resulting in tunable device properties.

Advanced Science, EarlyView.Existing machine learning potentials remain limited in their ability to generalize across the broad chemical and structural variability of C–S–H. Here, a representative DFT‐labeled dataset is constructed through large‐scale model generation, redundancy‐controlled screening, first‐principles optimization, and targeted sampling of non‐equilibrium ...

Micromechanics Modeling Of Strength For Nanocrystalline Copper
, 2008 We present a model in this paper for predicting the inverse Hall-Petch phenomenon in nanocrystalline (NC) materials which are assumed to consist of two phases: grain phase of spherical or spheroidal shapes and grain boundary phase. The deformation of the

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing
Advanced Electronic Materials, EarlyView.By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Drift Reduction in 2D PtSe2 Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge
Advanced Electronic Materials, EarlyView.Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common‐mode drift. We apply the WSB concept to highly sensitive piezoresistive pressure sensors made with two‐dimensional layered platinum diselenide transducers.
