Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media

open access: yesAdvanced Materials Technologies, EarlyView.
Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

Biodegradable and Edible Milli‐Fluidic Logic Circuits

open access: yesAdvanced Materials Technologies, EarlyView.
Fully biodegradable and edible fluidic circuits are developed using gelatin‐based valves that operate at low pressure. Logic gates, a one‐bit memory, and a ring oscillator are demonstrated, showing that biodegradable materials can perform computation and control.

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

Near‐Field Nanoimaging of Programmable Phase Transitions in Ga+‐Irradiated VO2

open access: yesAdvanced Optical Materials, EarlyView.
Focused Ga+ ion irradiation locally reprograms the insulator‐to‐metal transition in VO2 thin films. Infrared and terahertz near‐field nanoimaging reveals that low irradiation doses localize the resistive‐switching filament within the defect region, while high doses suppress switching there and redirect the filament into pristine VO2.
