Fully Passive Electrochemical Oxygen Sensor Enabled With Organic Electrochemical Transistor

open access: yesAdvanced Materials Technologies, EarlyView.
A wireless oxygen sensor that operates with low power without batteries, using organic electrochemical transistors (OECTs) powered by near‐field communication (NFC) is presented. The sensor combines an oxygen‐permeable membrane and a gel electrolyte to detect oxygen in air and complex liquids, making way for sustainable sensor technologies.

Anti‐Counterfeiting Tags with Camouflaged QR Codes on Nanocavities, Using Polymer‐Dispersed Liquid Crystals

open access: yesAdvanced Materials Technologies, EarlyView.
A QR code, printed through a commercial printer on a thin plastic foil, pre‐coated with a nanocavity is proposed as an anti‐counterfeiting label. Nanocavity imparts distinctive optical properties in terms of light reflection and transmission. A thin layer of polymer‐dispersed liquid crystals (PDLC) is used to camouflage the QR code, that become ...

Enhanced Sensitivity in Low‐Energy Inverse Photoemission Spectroscopy with an Off‐Axis Parabolic Mirror for Efficient Light Collection

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents an enhancement in the sensitivity of inverse photoemission spectroscopy (IPES) by more than 20 times by utilizing a custom‐made off‐axis parabolic mirror for improved light collection. Combined with ultraviolet photoemission spectroscopy (UPS), the enhanced sensitivity of our IPES setup allows for comprehensive mapping of interface ...
