A Sustainable Adhesive Paradigm: Reversibly Reinforcing, Heat‐Free Bonding with Universal Substrates

open access: yesAdvanced Science, EarlyView.
A heat‐free adhesive system, delivering superior adhesion strength across metal, plastic, and glass substrates, is developed. Repeatable bonding with reinforcement instead of strength reduction enables error‐tolerant applications. This design paradigm establishes an eco‐friendly alternative to conventional adhesives, particularly suitable for ...

Coordination‐Locked Engineering to Achieve Narrowband Room Temperature Phosphorescence in Non‐Rare Earth Metal–Organic Frameworks

open access: yesAdvanced Science, EarlyView.
In this contribution, the coordination‐locked phosphorescence amplification (CLPA) strategy is developed to successfully construct the first non‐rare‐earth narrowband RTP MOF crystal, Sr–tbc. In addition, Sr–tbc shows potential applications in high‐resolution afterglow display and multilevel information recognition.

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.
