Multispectral Photonic Structural Colors via Enhanced Interfacial Interference of Ultrathin Cellulose Nanofiber/MXene Films

open access: yesAdvanced Science, EarlyView.
Fabrication of CNF‐MXene free‐standing films: Ti3C2Tx MXene flakes integrated into a cellulose nanofiber (CNF) matrix through layered self‐assembly using vacuum‐assisted filtration. The layered structure of 4 µm thickness is displayed on SEM image.

Striking Impact of Solvent Polarity on the Strength of Hydrogen‐Bonded Complexes: A Nexus Between Theory and Experiment

open access: yesAngewandte Chemie, Volume 137, Issue 12, March 17, 2025.
The conventional belief that the stability of H‐bonded complexes decreases in a more polar solvent is being questioned in this study. Our analysis indicates that the stability of neutral H‐bonded complexes increases in a more polar solvent, provided there is substantial charge transfer between the subsystems.

A Sub‐Diffraction‐Limit Dimension All‐Plasmonic Optical Memory Using Non‐Linear Photochromism

open access: yesAdvanced Science, EarlyView.
An all‐plasmonic optical memory is demonstrated by using nonlinear plasmonics on a sub‐diffraction limit plasmonic nanowire waveguide coated with a photochromic diarylethene that supports the complete memory processes, “Write”, “Erase”, and “Readout” the memory ON/OFF states. Abstract The development of compact, high‐speed, and energy‐efficient optical

Near‐Infrared Light‐Induced Spin‐State Switching Based on Fe(II)−Hg(II) Spin‐Crossover Network

open access: yesAngewandte Chemie, Volume 137, Issue 12, March 17, 2025.
The temperature and light‐dependent synergistic switching effects in magnetic, structural, and spectral properties have been discovered for a three‐dimensional spin‐crossover (SCO) material [FeII(4‐acetylpyridine)2][HgII(μ‐SCN)4]. Tunable terahertz absorption through temperature and light stimuli is associated with phonon vibrations around Fe2 centers ...

Machine‐Learning‐Assisted Understanding of Depth‐Dependent Thermal Conductivity in Lithium Niobate Induced by Point Defects

open access: yesAdvanced Electronic Materials, EarlyView.
Thermal conductivity, a fundamental property of lithium niobate, plays a pivotal role in determining its device performance. By integrating experiments with machine‐learning‐assisted simulations, this study demonstrates that oxygen vacancies induced by thermal reduction result in a pronounced suppression of thermal conductivity and a marked depth ...

Blue‐to‐Green Fine‐Tunable Narrowband Delayed Fluorescence in Peripherally Dendritic Modified Bis‐Indolocarbazoles

open access: yesAngewandte Chemie, EarlyView.
An exquisite color tuning of narrowband thermally activated delayed fluorescence from deep‐blue to green was achieved for non‐boron ubiquitous luminophores based on the dendritic modification design concept. The corresponding OLEDs exhibited high‐efficiency, high‐color‐purity blue and green electroluminescence, with high external quantum efficiencies ...

Ru Single Atoms Anchored on Co3O4 Nanorods for Efficient Overall Water Splitting under pH‐Universal Conditions

open access: yesAdvanced Energy Materials, EarlyView.
A Ru8%‐Co3O4 catalyst containing Ru single atoms (SAs) exhibits exceptional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance in acidic, neutral, and alkaline media. When used as the anode and cathode catalysts in an anion exchange membrane water electrolyzer (AEMWE) device, a low cell voltage of just 2.06 V is needed to
