Selective Charge Extraction Allows Fast Photomultiplication and Imaging in Rigid and Ultra‐Flexible SWIR Organic Photodiodes

Advanced Energy Materials, EarlyView.
SWIR donor polymer TQ‐3T allows photomultiplication in OPD in 1:1 ratio with NFA Y6, achieving EQEs > 1100% at ‐10 V. Microseconds response times are retained, amongst the lowest for photomultiplication. As proof of concept, we demonstrate ultrathin and flexible PM‐OPDs based on our TQ‐3T:Y6 as a flexible pulse oximeter as well as a conformable image ...

Surface‐State–Regulated Product Distribution in Photothermal CO2 Hydrogenation Over MXene‐Based S‐Scheme Catalyst

Angewandte Chemie, EarlyView.
This work establishes an MXene‐based S‐scheme heterojunction in which the cooperative interplay among metallic Ni, surface NiOx domains, and conductive Ti3C2Clx drives efficient charge separation and photothermal coupling. Progressive evolution of Ni surface states regulates the CH4/CH3OH product distribution by modulating interfacial energetics and ...

Wearable Metamaterials with Embodied Intelligence for Programmable Control of Human Limbs Tremor

Advanced Intelligent Systems, EarlyView.
Resulting from alternating muscle contractions, tremors can severely limit human ability to perform everyday tasks like walking or talking, due to their disruptive nature. Medication and surgery may not always effectively address tremor control. A wearable device embodying programmable smart metamaterials with adaptable intelligence to meet the demand ...

Systematic Study of PDMS Optical Waveguides for Pressure Sensing Using Design of Experiments

Journal of Applied Polymer Science, EarlyView.
A response surface methodology was used to systematically evaluate the impact of mix ratio and cure conditions on PDMS optical waveguide properties for pressure sensing. Mix ratio significantly influenced compression sensitivity, compressive modulus, and propagation loss, while cure temperature primarily affected refractive index.
