Dendronized Encapsulation with Hierarchical Rigidification Enabling Robust Solution Room‐Temperature Phosphorescence, Efficient Electroluminescence and Ultralong Afterglow

open access: yesAdvanced Science, EarlyView.
The organic RTP's rigidity‐flexibility conflict via multiscale confinement is resolved. Dendronized donor‐acceptor with alkyl carbazoles enables intramolecular encapsulation and stability of triplet excitons, achieving 9 ms solution RTP. Combined with aggregation/PMMA doping, this suppresses nonradiative decay, achieving 72% film PLQY/17.2% OLED EQE ...

Ultra‐Robust Conductive Hydrogels Enabled by a Gradient Bond‐Breaking Pseudo‐Drying Strategy

open access: yesAdvanced Science, EarlyView.
A bioinspired PVA‐ANFs hydrogel, engineered via novel gradient bond‐breaking, achieves unprecedented mechanical performance: ultrahigh strength (≈18 MPa), modulus (≈12 MPa), toughness (≈74 MJ/m3), and record fracture energy (≈269 kJ m−2). It exhibits cryogenic flexibility (−70°C), high ionic conductivity (936.3 mS m−1), and biocompatibility.

Design Principles for Deployable Fibers Inspired by Hagfish Defense

open access: yesAdvanced Science, EarlyView.
Hagfish slime deploys fibers from coiled skeins to form an ultra‐dilute, water‐trapping network. Inspired by this mechanism, design principles are established for synthetic skeins, fabricated with tightly coiled fibers that unravel under flow. These synthetic skeins demonstrate deployable fibrous networks, highlighting generalizable strategies for ...

Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe

open access: yesAdvanced Science, EarlyView.
We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

Foldable Soft Leg‐Assisted Wheel Robot

open access: yesAdvanced Science, EarlyView.
Recently, soft robots garner attention for designing the robotic legs of mobile robots due to their characteristic lightness, tunability, and simple control. Here, a novel soft foldable leg capable of high stiffness and deformability is identified as an assistant for enhancing the locomotion capabilities of a wheel mobile robot.
