Scalable Fabrication of Electrochemical Sensors Via Inkjet Printing of Functionalized Graphene for Pesticide Detection

open access: yesAdvanced Materials Technologies, EarlyView.
Inkjet printing enables uniform, reproducible, and stable deposition of nitrogen‐doped graphene acid (NGA) on screen‐printed electrodes, outperforming traditional drop‐casting. The resulting electrochemical sensor exhibits enhanced sensitivity, long‐term stability, and efficient imidacloprid detection.

Beam Combining of a Tunable Tilted Quantum Cascade Laser Array

open access: yesAdvanced Photonics Research, EarlyView.
The four‐channel tilted waveguide with varying angles in the quantum cascade laser array, achieving a free tuning range of 100 nm and common‐aperture output simultaneously, is reported. The fabrication eliminates the necessity of electron‐beam lithography and is very promising for mass production in gas sensing industry.
