Photoluminescent UV Light Modulation via Anisometric Carbon Nanodots for UV–Visible Shutter and UV Sensor

Advanced Functional Materials, EarlyView.
Anisometric carbon nanodots are synthesized directly from a liquid crystal precursor and embedded into polymer network liquid crystals to create soft, multifunctional photonic films. These hybrid devices exhibit polarized photoluminescence, broad UV absorption, and fast, electrically tunable light modulation.

Ultrabroadband Chiral Emission from Cu Nanocluster Eggshell Membrane/CsPbBr3 QD Composites with a Cholesteric Superstructures

Advanced Functional Materials, EarlyView.
This study presents a novel wide‐bandwidth circularly polarized luminescence (CPL) system combining Cu nanoclusters, perovskite quantum dots, and cholesteric liquid crystals. The design achieves strong CPL emission across 480–750 nm (glum up to 1.31 at 514 nm and 1.46 at 620 nm). Using biomaterials and a simple structure, it offers a promising strategy

Interfacial Control of Degradation Pathways in 2D Heterostructures

Advanced Functional Materials, EarlyView.
The stability of two‐dimensional (2D) heterostructures is governed not only by their intrinsic chemistry but also by interfacial effects. This study reveals how metallic versus insulating substrates impact the oxidation of air‐sensitive 2H‐MoTe2. Metallic layers act as charge reservoirs, mitigating degradation, while insulating ones accelerate it ...

A Holistic Exploration of the Potentially Recoverable Redshift Information of Stage IV Galaxy Surveys

The Astrophysical Journal
Extragalactic science and cosmology with Stage IV galaxy surveys will rely almost exclusively on redshift measurements derived solely from photometry, which are subject to systematic and statistical uncertainties with numerous analysis choices.

Spatially Resolved Click Patterning of Dyes on Graphene for 2D Hybrids with Regiotunable Fluorescence

Advanced Functional Materials, EarlyView.
Well‐structured graphene hybrid architectures featuring spatially resolved fluorescent properties represent a promising but so‐far elusive synthetic target. A robust and straightforward method for fabricating well‐organized graphene‐dye hybrid nanoassemblies through a combination of reductive patterning and conventional click chemistry is presented ...

The Intracluster Light Analysis of the Most Evolved Systems of Galaxies: Fossil Groups

The Astrophysical Journal Letters
We present the analysis of the intracluster light (ICL) in three fossil groups, RX J085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ∼ 0.1. We used two optical broadband filters, F435W and F606W, observed with the Hubble Space Telescope, and ...
