One‐Step Synthesis of Size‐Controlled Copper Oxide Nanoparticles on Laser‐Induced Graphene Sensor for L‐Cysteine Detection

Advanced Electronic Materials, EarlyView.
Oxygen plasma treatment enhances polyimide hydrophilicity and promotes uniform anchoring of copper ion precursors. A one‐step laser process then generates CuO‐decorated nanoparticles on laser‐induced graphene (LIG) electrodes, enabling controlled nanoparticle growth via precursor concentration tuning.

A Compact Resistively Loaded Metamaterial Absorber for 2.4 GHz RF Energy Harvesting With Impedance‐Matched Rectifier Analysis

Advanced Electronic Materials, EarlyView.
A compact resistively loaded metamaterial absorber captures RF energy at 2.4 GHz and directs most of the accepted power to modeled loads. The resonant response is confirmed experimentally for the fabricated absorber, while an impedance‐matched rectifier is evaluated through simulation. The stage‐wise results distinguish absorber, rectifier, and cascade
