Electrochemical‐Doping of Tungsten on Nickel‐Boron‐Phosphide Microspheres for Accelerated Industrial‐Scale Water Electrolysis at High Current Density

open access: yesAdvanced Materials Technologies, EarlyView.
The bifunctional W/NiBP (+) || W/NiBP (−) demonstrates superior overall water splitting (OWS) performance as compared to the benchmark of Pt/C (+) || RuO2 (−). Notably, the W/NiBP (+, −) exhibits an ultra‐low cell voltage of 2.68 V at 2000 mA cm−2 high current density as compared to the benchmark value of 3.29 V.

Progress in Surface Plasmon and Other Resonance Biosensors for Biomedical Applications

open access: yesAdvanced Materials Technologies, EarlyView.
This is the shortened version: Recent advancements in surface plasmon resonance and other optical resonance biosensors for biomedical applications are presented. Advanced sensing strategies are examined for the detection of diverse analytes, integration of nanomaterials and machine learning, and emerging nonplasmonic modes like guided mode resonance ...

All‐Optically Driven Optofluidic Light Modulator

open access: yesAdvanced Optical Materials, EarlyView.
In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within
