Bayesian‐Optimized Dual‐Mode Luminescence‐Based Optical Thermometry Enabled by Negative Thermal Expansion in Lu2(MoO4)3:Yb–Er–Tm Phosphor

Advanced Optical Materials, EarlyView.
A Bayesian optimization framework identifies the ideal composition for Lu2(MoO4)3:Yb–Er–Tm phosphors with minimal experimental trials. By leveraging the host's negative thermal expansion, the material achieves remarkable thermal quenching compensation.

Efficient multicolor X-ray excited persistent luminescence enabled by Gd-mediated trap clusters

Nature Communications
Persistent luminescence materials are promising for night-vision displays, background-free medical diagnostics, and high-resolution radiography, yet achieving efficient violet, yellow, and red emission within a single robust and scalable host remains a ...

X–ray–sensitive drug delivery model based on citrate–modified Tb–doped hydroxyapatite nanoparticles for photopharmacology and photodynamic therapy

Hybrid Advances
This study develops and investigates a novel model for targeted drug delivery using X–ray–induced luminescence. Hydroxyapatite doped with terbium and modified with citrate groups (HA:Tb/Citr) was synthesized by co–precipitating Ca2+ and Tb3+ ions with ...

Circularly Polarized Red‐NIR Emission With High Dissymmetry Factor From Achiral [Mo6I8(OCOC2F5)6]2− Cluster Anion Embedded in a Bent‐Core Liquid Crystal Host

Advanced Optical Materials, EarlyView.
Associating a chiral bent core liquid crystal molecule, that self‐assembles into helical nanofilaments, with an achiral red‐NIR phosphorescent octahedral molybdenum cluster produces a hybrid material exhibiting efficient red‐NIR circularly polarized emission under UV excitation.

Natural Products Inspired Scaffold Diversification Leads to Unnatural Molecular Warhead and Covalent Strategy to Modulating Protein Function through Electrophilic Bromine Transfer

Advanced Science, EarlyView.
We report a new thiolate‐reactive α,α‐gem‐dibromo lactam warhead that activates transcription factor Nrf2 and demonstrates anti‐inflammatory activities, which have implications in cancer, neurodegeneration, and cardiovascular diseases. RNA‐seq illuminated detailed transcriptional profiles, and chemical reactions with cysteine‐containing compounds ...
