Metalens‐Enabled Twisted Chromatic Dispersion

open access: yesAdvanced Physics Research, EarlyView.
We successfully demonstrate visible broadband twisted dispersion metalenses. As a proof of concept, we realized two distinct devices: the conical helical and the spring‐like dispersion‐controlled metalenses. These results rigorously validate the universality of our approach in customizing arbitrary continuous 3D dispersion trajectories, thereby ...

2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

open access: yesBMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Productivity and Emissions in Italian Agriculture: A Farm‐Level Efficiency Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Achieving the European Union climate‐neutrality objectives requires metrics that jointly assess farm productivity and greenhouse gas emissions at a granular level. However, harmonized evidence for benchmarking the productivity–emissions nexus of Italian farms remains limited.

Self‐Assembled Luminescent Au(I)–Adamantylamine Coordination Polymer Needles With Thermoresponsive Optical Properties

open access: yesChemistry – A European Journal, EarlyView.
A self‐assembled hydrophobic and red phosphorescent Au(I) coordination polymer (CP) was synthesized under mild conditions. Single‐crystal X‐ray diffraction (XRD) demonstrated linear Au(I) chains stabilized by aurophilic and hydrogen bonding interactions.

Experimental and numerical analysis of the chromatic dispersion dependence upon the actual profile of small core microstructured fibres

open access: yes, 2006
International audienceThe chromatic dispersion curve of the fundamental mode in small core microstructured fibres (SCMF) is both calculated using a Finite Element Method (FEM) and measured with a low coherence interferometric method.

Amine‐Triggered Azabenz‐Annulation of Cyclic Secondary Amine‐Functionalized Perylene Diimides for Dual‐Mode Sensing

open access: yesChemistry – A European Journal, EarlyView.
Pictet‐Spengler Intermediate of a cyclic secondary amine perylene diimide undergoing amine‐triggered conversion to azabenz‐annulated perylene diimide, inducing a high‐contrast green‐to‐yellow color change along with fluorescence turn‐on, demonstrating intuitive “safe” to “warning” dual‐mode sensing.

The C‐Terminal Regions of TRAK Proteins Contain MIRO‐Independent Mitochondrial Localization Domains

open access: yesCytoskeleton, EarlyView.
ABSTRACT Current models suggest that MIRO GTPases anchor cytoskeletal motors to the mitochondrial outer membrane (MOM). However, our previous findings indicate that the unconventional myosin, MYO19, interacts with MIRO weakly and that a MIRO‐independent MOM‐localizing domain interacts more tightly with the MOM.

Molten Zinc Coordination Polymer Glass as a Host for Stable and Processable Optical Dye Composites

open access: yesEcoEnergy, EarlyView.
Zinc‐based coordination polymer glass is employed to suppress aggregation‐caused quenching (ACQ) and enhance molecular stability, enabling improved luminescence performance in the solid state. The emission color of the hybrid composites can be tuned by varying the incorporated guest molecules, while the glass matrix effectively prevents aggregation and

Highly Efficient Sky‐Blue Perovskite Quantum Dot Light‐Emitting Diodes via Ligand‐Assisted Trap‐State Passivation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,
