Engineering of Multi‐Dynamic Bonds Toward Room‐Temperature Self‐Healing Epoxy/MXene Adaptable Network with Record‐High Toughness

open access: yesAdvanced Science, EarlyView.
Inspired by mussel nacre and byssus, a multi‐type dynamic chemically bonded epoxy/MXene adaptable network is fabricated through a hierarchical assembly strategy, establishing the toughest (210.75 MJ m−3) room‐temperature self‐healing (90.04% recovery within 2 h at 25 °C) epoxy resin to date, challenging the limitations of conventional thermosetting ...

Achieving Highly Roust Polymeric Microspheres with Efficient and Full‐Color Organic Afterglow for 3D Printing and Anti‐Counterfeiting

open access: yesAdvanced Science, EarlyView.
Highly robust polymeric microspheres with efficient ultralong organic phosphorescence, dual‐mode organic afterglow, and persistent fluorescence are developed by embedding different organic luminogens into melamine‐formaldehyde polymer matrices. Their organic afterglow quantum yields and lifetimes are up to 18.0% and 1.39 s under ambient conditions ...

Circular Polarimetric Imaging with a Metamaterial Integrated Long‐Wavelength Infrared Focal Plane Array

open access: yesAdvanced Science, EarlyView.
A quantum well infrared photodetector based long‐wavelength infrared division‐of‐focal‐plane‐array circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta‐mirror structure array is established. The device achieves a circular polarization extinction ratio of 5.67, a 9.13‐fold enhancement in responsivity, a noise equivalent ...
