Biomimetic Multiscale‐Structured Biomass Graphene/Polyurethane Sponge Composite for Flexible Pressure Sensors and Intelligent Cushioning Materials

open access: yesAdvanced Science, EarlyView.
In this study, a multifunctional conductive sponge composite (MAPU) is developed using a biomimetic, hierarchical construction strategy emulating the growth process of natural wood. This approach involved integrating biomass‐derived graphitic nanoflakes, synthesized from luffa vine (LVGN), into a polyurethane (PU) sponge matrix.

Scalable Photoactive NO2‐Sensing Framework for Plant Health Monitoring

open access: yesAdvanced Science, EarlyView.
A highly sensitive and selective NO2 gas sensor operates at room temperature using only ambient light, eliminating the need for external heating. Based on a scalable, 3D TiO2 nanoarchitecture, the device is integrated into a wireless platform and deployed on a plant. It successfully demonstrates real‐time monitoring of gas‐induced physiological stress,

Giant Isotope Effect in Metal–Organic Frameworks Boosts Unprecedented Photo‐ and Radio‐Luminescence Enhancement

open access: yesAdvanced Science, EarlyView.
Deuterated MOFs in this work exhibited unprecedented giant luminescence isotope effect via O─H oscillator suppression, achieving maximal solid‐state materials emission enhancement. This yields significantly improved X‐ray detection sensitivity and imaging resolution, marking the first integration of MOFs with isotopic luminescence and opening new ...
