In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

open access: yesSmall, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

Multi-output DC–DC converters based on diode-clamped converters configuration: topology and control strategy

open access: yesIET Power Electronics, 2010
This study presents a new DC DC multi-output boost (MOB) converter which can share its total output between different series of output voltages for low- and high-power applications. This configuration can be utilised instead of several single output power supplies. This is a compatible topology for a diode-clamed inverter in the grid connection systems,

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.
