Pyrolyzed Walnut Shell‐Based Flexible Electrodes for Magnetically Triggered ON/OFF DNA Release

open access: yesAdvanced NanoBiomed Research, EarlyView.
A magnetically actuated DNA release system using walnut shell‐derived electrodes enables ON/OFF switching of electron transfer by controlling DNA hybridization with magnetic beads. A magnetically gated, enzymatically driven DNA release platform based on sustainable pyrolyzed walnut shell‐derived carbon electrodes is reported.

Unveiling the Influence of Annealing Temperature on Properties of CZTSSe Nanocrystals

open access: yesAdvanced Physics Research, EarlyView.
This study investigates the synthesis and annealing temperature effects on CZTSSe nanopowders for photoelectrochemical water splitting. Using solution‐based methods, the research explores how temperatures from 100 to 350 °C influence morphology, structure, and optical properties. Findings reveal temperature‐dependent grain growth and structural changes,

Metasurface Doppler Cloak for Broadband Radar Stealth

open access: yesAdvanced Physics Research, EarlyView.
Suppressing the motion‐induced Doppler shift passes the target as part of the static clutter which is ignored by radars. Using a simple time‐modulation, frequency conversion is obtained from a metasurface‐based solution over a wide range. Referred to as a Doppler cloak, this work expands and validates such a varactor‐loaded prototype for broadband ...
