Mechanophores for Mechano‐Imaging in Polymeric Materials

open access: yesHelvetica Chimica Acta, EarlyView.
Mechanophore‐based mechanochromic systems convert mechanical forces in polymers into optical signals, enabling direct imaging of stress localization and molecular damage. This perspective highlights recent advances in mechanophore design and their use to probe local mechanics across diverse polymer matrices, and concludes by outlining opportunities for

Sustainable Isotropic Meta‐Wood‐Materials by Topological Reconstruction of Plant Fibers

open access: yesInterdisciplinary Materials, EarlyView.
Meta‐wood, a novel dense and hard sustainable material, is reconstructed by pure plant fibers without adhesive. It has a 3D network with fibers mechanically interlocked together. This unique structure gives it unique properties that are very different from traditional wood and paper.

Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

MXenes in Next‐Generation Light‐Emitting Diodes: Innovations, Challenges, and Future Prospects

open access: yesLaser &Photonics Reviews, EarlyView.
This review provides a systematic and critical overview of MXene integration in LEDs from their synthesis strategies and electronic characteristics to their roles as electrodes, interlayers, and emissive materials. It also explores the emerging prospects and challenges for MXene‐enabled flexible, transparent, and intelligent display technologies that ...
