Multifunctional Conductive Nanofibers for Self‐Powered Glucose Biosensors

open access: yesAdvanced Science, EarlyView.
This work develops a novel self‐powered glucose biosensor using polycaprolactone/polypyrrole/graphene oxide (PCL/PPy/GO) nanofibers integrated with a triboelectric nanogenerator. The system achieves high glucose detection sensitivity and generates 63 V from motion, combining robust mechanical strength with eco‐friendly energy harvesting.

A Rapid Cortical Learning Process Supporting Students’ Knowledge Construction During Real Classroom Teaching

open access: yesAdvanced Science, EarlyView.
There is growing interest in understanding how classroom teaching works, but previous theories and studies leave a gap in the neurocognitive mechanisms involved in real classroom teaching. Here we show that during real classroom teaching, students' middle frontal cortex serves as a hub of a rapid cortical learning process, supporting their knowledge ...

Ultrasound Cavitation Enables Rapid, Initiator‐Free Fabrication of Tough Anti‐Freezing Hydrogels

open access: yesAdvanced Science, EarlyView.
This work establishes a foundation for high‐performance sonogel fabrication using non‐focused and focused ultrasound, and demonstrates that ultrasound cavitation enables rapid, initiator‐free, and oxygen‐tolerant formation of hydrogels with superior mechanical and physical properties. .

Photo‐Rechargeable Organic Supercapacitor via Light‐Activated Electrolytes

open access: yesAdvanced Science, EarlyView.
A photo‐rechargeable organic supercapacitor device is fabricated comprising activated charcoal electrodes and 2‐nitrobenzaldehyde as the electrolyte. The operation principle of the device relies on the photoinduced transformation of 2‐nitrobenzaldehyde into electrochemically active benzoic acid derivatives.

Perceived safety in community and service settings among young adults experiencing homelessness: Differences by sexual and gender identity

open access: yesAmerican Journal of Community Psychology, Volume 70, Issue 3-4, Page 340-351, December 2022., 2022
Abstract Homelessness poses risks to the health and safety of young adults; particularly among sexual and gender minority (SGM) young adults. The current study sought to better understand service use and perceived safety in community and service settings among SGM and cisgender heterosexual (cis‐hetero) young adults experiencing homelessness. Data come
