Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

open access: yesAdvanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...

Oxygen Vacancy‐Enriched Platinum Single‐Atom Nanozyme Wrapped in Nanoislands: Unlocking Catalytic Activity and Reprogramming Redox Microenvironment for Osteonecrosis Repair

open access: yesAdvanced Science, EarlyView.
CeO2‐x/Pt single‐atom nano‐island is constructed via low‐temperature reduction, featuring abundant oxygen vacancies and an island–sea structure. It delivers outstanding multi‐enzyme‐mimetic activity and ROS‐scavenging efficiency. Density functional theory reveals optimized electronic structures and reaction pathways.

Automated Extraction of Multicomponent Alloy Data Using Large Language Models for Sustainable Design

open access: yesAdvanced Science, EarlyView.
A large language model (LLM) based pipeline is developed to automatically extract a comprehensive and accurate multicomponent alloy database from literature corpus. The extracted dataset is integrated with sustainability indicators to identify potential alloys that outperform existing industrial benchmark materials in terms of both performance and ...

Image Forgery Detection and Localization [PDF]

open access: yes, 2015
Con la continua diffusione di strumenti software semplici e potenti per editare le immagini, la contraffazione di immagini è diventata sempre più comune; contemporaneamente si è diffuso l'interesse per l'image forensic cioè quelle metodologie e algoritmi capaci di rilevare l'integrità dell'immagine.

In Situ Confinement of 0D Halometallates Within Deep Eutectic Solvents: From Systematic Screening to Metal‐Tunable Luminescence for Anti‐Counterfeiting Eutectogels

open access: yesAdvanced Science, EarlyView.
We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.
