Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Enhanced Polariton Interactions in Suspended WS2 Monolayer Microcavity

Advanced Materials, EarlyView.
Monolayers of transition‐metal dichalcogenides exhibit strong exciton resonances for light‐matter interactions at RT, though substrate effects limit performance. This work presents a planar microcavity with a suspended WS2 monolayer, eliminating substrate‐induced losses.

Mechanochromic, Low‐Cost, and Structurally Colored Displays Using Biodegradable Hydroxypropyl Cellulose

Advanced Materials, EarlyView.
Mechanochromic hydroxypropyl cellulose (HPC) integrated with microfluidic devices creates scalable, eco‐friendly reflective color displays. We demonstrate mechanochromic displays with 500 µm pixel size and 5Hz switching rates with room for optimisation. The proposed mechanochromic HPC displays are an initial step toward more environmentally responsible

Scalable Lithium Niobate Nanoimprinting for Nonlinear Metalenses

Advanced Materials, EarlyView.
A broadband polycrystalline lithium niobate platform is developed for highly versatile and scalable fabrication of nonlinear metasurfaces. This work demonstrates simultaneous second harmonic generation and wavefront‐shaping via a metalens on this platform.
