Bending‐Resistant Intimate 3D Graphene–Metal Heterojunctions for Highly Sensitive and Robust Flexible Sensors

Advanced Science, EarlyView.
A reservoir‐guided silver‐nanoparticle soldering strategy is developed for bending‐resistant 3D graphene–metal heterojunctions. Controlled hot‐plate evaporation confines conductive ink within the metal reservoir, suppressing spreading and protecting the LIG interface from deformation‐induced fracture.

Bypassing Pre‐Photoactivation in High‐Barrier Polyamide for Robust and Scalable Organic Persistent Luminescence

Advanced Science, EarlyView.
A universal paradigm resolves the trade‐off between ambient stability and barrier properties in organic persistent luminescent (OPL) polymers. By interlocking chromophores within a high‐barrier MXD6 matrix, we achieved no Pre‐photoactivation OPLs with exceptional long‐term stability in water.
