Thermo‐Responsive Tri‐State Photonic Crystals

open access: yesAdvanced Science, EarlyView.
Tri‐state photonic crystals combine thermochromic structural color, fluorescence, and afterglow via far‐field absorption tuning, bypassing the efficiency‐lifetime trade‐off of TS‐FRET. This enables dynamic, high‐capacity anti‐counterfeiting with tunable optical states.

Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

open access: yesAdvanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

Cellulosic Functional Bioplastic with Tunable Strength and Toughness Through Heat‐Treatment of Dynamic Covalent Networks

open access: yesAdvanced Science, EarlyView.
A fully bio‐based dynamic covalent network is constructed via Diels‐Alder chemistry between furan‐modified cellulose derivatives and bismaleimide‐functionalized lignin. This system enables tunable strength‐ductility balance through heat‐treatment and exhibits excellent recyclability.

Direct Observation of Suppressed Optical–Acoustic Phonon Energy Coupling in Supported SWCNT at Cryogenic Temperatures

open access: yesAdvanced Science, EarlyView.
This study quantifies the temperature‐dependent optical–acoustic phonon coupling factor (GOA) in supported single‐walled carbon nanotubes, revealing significant suppression at low temperatures. At high temperatures, GOA increases monotonically and is attributed to intensified anharmonic phonon interactions. This research offers key insights into phonon
