Toward Two‐Dimensional Metallic Topologies in Atomically Precise Nanoclusters
06/10/2026 - We present that hub‐driven ring fusion enables the synthesis of a Pd11 cluster featuring a fused tri‐pentagonal topology. The resulting Pd11, featuring a centrally driven fused tri‐pentagonal...
Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites
25/09/2026 - Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ...
Photon–Phonon Co‐Driven Ammonia Synthesis Over Ru/BaTiO3 Under Very Mild Conditions
16/09/2026 - Photon‐generated electrons dynamically enrich Ru sites on BaTiO3, suppressing excessive hydrogen coverage while promoting N2 adsorption and dissociation. Coupled photon and phonon...
Development of a sequential digestion workflow for dual-platform microplastic analysis in pasteurized donor human milk using µ-FTIR and Py-GC/MS
- Reliable determination of microplastics in complex biological matrices remains analytically challenging because of high lipid and protein content, low particle abundance, and the risk of polymer...
Ligand‐Dependent Electronic Modulation of Conjugated Metal–Organic Frameworks Enables Efficient Electrocatalytic Nitric Oxide Reduction to Ammonia
08/09/2026 - A p‐type tetraazanaphthotetraphene ligand enables precise control over single‐atom Ni sites in a hollow conductive MOF, accelerating proton transfer and hydrogenation kinetics for...
Single‐Source Polymer‐Derived SiC/HfC Composites: Cross‐Linking Mechanism, Microstructure, and Oxy‐Propane Ablation Resistance
04/09/2026 - A single‐source SiC/HfC precursor is synthesized from polysiloxane and Hf(acac)4, followed by pyrolysis and spark plasma sintering to produce dense composites. With 20 wt% Hf modification, the...
Synergistic Thermal Energy and Charge Carriers in an Fe‐MOF for Solar‐Driven Scalable and Selective Aniline Production
05/09/2026 - We report NM‐101, a scalable Fe‐MOF that efficiently converts nitro compounds to anilines using sunlight. With high photothermal efficiency (58%) and a record TOF of 226.2 h−1, it enables...
