Chromaticity Control in Light‐Emitting Electrochemical Cells via Thermally Activated Emission in Assemblies of a BN‐Doped Pyrenyl Hydrocarbon

Advanced Functional Materials, EarlyView.
The successful color control in light‐emitting electrochemical cells based on highly emissive green‐emitting BN‐doped polyaromatic hydrocarbon with thermally activated NIR emitting assemblies. Abstract This work outlines the synthesis and photo‐/electro‐luminescent behavior of a new C‐shaped BN‐doped benzenoid hydrocarbon using N‐directed borylation in

Enhancing Metal‐Support Interactions of Ru Catalysts via Relaxation of Oxygen Vacancies for Hydrogen Production

Advanced Functional Materials, EarlyView.
Designing stable Ru nanoparticle catalyst remains a critical challenge in electrochemical applications. Here, a strategy is presented to stabilize Ru catalysts by leveraging Ce‐doped ZrO2 supports (ZrCeO2‐x), which enhance catalyst durability and activity through electronic metal‐support interactions and stabilized oxygen vacancies.

Near‐Field Optical Detection of Defect‐Stabilized Metallic Islands at the Verwey Transition in Fe3O4

Advanced Functional Materials, EarlyView.
Nanoscale metallic islands emerging across the Verwey transition in thin films of Fe3O4 are imaged using near‐field optical microscopy from mid‐infrared to terahertz frequencies. Recurring across thermal cycles, these disorder‐stabilized islands exhibit distinct transition temperatures.

Wavelength‐Dependent Differential Amplification of Raman Scattering by Chiral Gold Nanorods for Multiplexed Encoding

Advanced Functional Materials, EarlyView.
The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Ultraviolet–Visible Spin‐Resolved Chip‐Scale Spectroscopy

Advanced Functional Materials, EarlyView.
By harnessing phase, wavelength, and spin multiplexing, the proposed meta‐spectrometer enables spin‐resolved spectral analysis within a compact footprint. The presented dual‐band (320–450 nm) spin‐resolved meta‐spectrometer features enhance optical functionality, allowing for the simultaneous discrimination of spectral content and spin states of light ...
