Electronic Structure Modulation in Dopant‐Controlled Single‐Atom Graphene Catalysts for Efficient Hydrogen Evolution: A Machine Learning and First‐Principles Study

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
First‐principles DFT calculations and machine learning analysis show that heteroatom doping of graphene (G) significantly enhances the stabilization of transition‐metal single atoms by strengthening metal–support interactions and increasing charge transfer. N‐doped G exhibits higher adsorption energies, lower d‐band centers, and shorter TM–G bonds than

Glycerol‐Modified Biphasic Silicone Gel for Synergistic Thermal Transport and Dielectric Reliability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surfactant‐free glycerol‐modified biphasic silicone gel establishes metastable liquid interfaces that simultaneously enhance phonon transport and induce deep traps (1.28 eV), enabling synergistic electrothermal performance of enhanced thermal conductivity (+33.3%), thermal diffusivity (+48.3%), and DC breakdown strength (+57.6%) with suppressed space

Left atrial function in uraemic patients: Four‐dimensional automatic left atrial quantitative technology study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1316-1325, April 2025.
Abstract Objective This study aimed to evaluate the utility of left atrial volume and function in uraemic patients using four‐dimensional automatic left atrial quantification (4D auto LAQ) technology. Methods Thirty‐four undialysed uraemic patients (U‐ND group), 60 dialysed uraemic patients (U‐D group), and 32 healthy volunteers (N group) were enrolled

The Synthesis Use of a Difluorinated Amino‐Benzo‐Cinnoline Dyes (ABCDyes) Enables Fine Tuning of Emission Through Double SNAr Late‐Stage Functionalization

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient synthesis of difluorinated amino‐benzo‐cinnoline dyes (ABCDyes) is reported. Their use for the late‐stage introduction of internal dinucleophilic species through a double SNAr reaction enables straightforward access to previously unexplored ABCDye analogs displaying tunable emission ranging from green to red.

Defective CeO2/Copper Phthalocyanine S‐Scheme Heterojunctions With Molecular Copper Centers for Selective CO2‐To‐CO Photoconversion

open access: yesElectron, EarlyView.
Defective CeO2/CuPc S‐scheme heterojunction featuring oxygen‐vacancy‐rich ceria nanorods and atomically dispersed Cu–N4 molecular centers. Built‐in electric field mediates efficient S‐scheme charge separation, accumulating strongly reductive electrons at copper sites for selective CO2‐to‐CO photoconversion (92.2% selectivity) via *COOH stabilization ...
