Gradient‐Integrated High‐Strength and High‐Toughness Cellulose Triboelectric Materials for Enhanced Charge Storage and Transport

Advanced Science, EarlyView.
Inspired by the gradient structure of sea urchin spines, a gradient‐integrated cellulose/multi‐walled carbon nanotube (MWCNT) triboelectric material is constructed. A compatible interface and built‐in electric field synergistically suppress charge dissipation, achieving 20.5 nC cm−2 surface charge density, 8044‐cycle stability, 126.33 MPa tensile ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

Advanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐

Direct Electrocaloric Characterization of Polyvinylidene Fluoride‐Based Co‐ and Terpolymers Over a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A systematic study of polyvinylidene fluoride‐based copolymers and terpolymers over a broad temperature range shows that commercially available polymers can compete with the best electrocaloric ceramics, exhibiting a large electrocaloric effect of ∼4.5 K in several compositions.
