In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

A high‐resolution mechanoluminescence (ML) platform is achieved through chromatic filtration strategy using a conjugated polymer shell (F8BT) on copper‐doped zinc sulfide microparticles. This shell narrows the emission bandwidth, selectively filtering out blue noise, while simultaneously boosting intensity via ML photon recycling process.

Detecting the Six Polytypes of Five‐Layer Graphite
The six possible periodic crystals—so‐called polytypes of Penta layer graphene are identified using Raman, second harmonic, and electric surface potential measurements. The measurements reveal the polytypes’ abundance, relative stability, and annihilation dynamics, crucial for future multiferroic SlideTronic applications.

Pt‐impy and Pt‐Me‐impy exhibit external quantum efficiencies of 24.5% and 27.4% at the 3 wt.% doping concentration, respectively. In particular, Pt‐impy and Pt‐Me‐impy doped blue PhOLEDs optimized for stability demonstrate a device lifetime of up to 95% of the initial luminance of 543 and 228 h at 1000 cd m−2, which has never been achieved in the blue ...
