Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts

Advanced Science, EarlyView.
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...

Study on Geological Deformation of Supercritical CO₂ Sequestration in Oil Shale after In Situ Pyrolysis

Energies
After the completion of in situ pyrolysis, oil shale can be used as a natural place for CO2 sequestration. However, the effects of chemical action and formation stress-state changes on the deformation of oil shale should be considered when CO2 is ...

Tri‐Functional Electrocatalysis for Zinc–Air Battery Coupled Water Splitting: A Catalyst‐Electrode‐Device‐System Perspective

Advanced Science, EarlyView.
This review establishes a catalyst–electrode–device–system framework for tri‐functional HER/OER/ORR electrocatalysis that couples water splitting with Zn–air batteries. Five catalyst families are covered: noble‐metal, metal‐based, single‐atom, heterostructure, and metal‐free systems.

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Selective Product Enhancement in an Auger Reactor: Pyrolysis of Pine Bark through In Situ Recirculation of Pyrolysis Vapors

Energy & Fuels
In biomass pyrolysis, final product selectivity is governed not only by major reaction conditions like temperature and heating rate but also by complex vapor-solid interactions and secondary reactions. Yet, the influence of internal flow configuration on pyrolysis vapor remains poorly understood in continuous pyrolysis systems.

Interface‐Enhanced Electrochemical Epoxidation Over a Core‐Shell Nanozeolite TS‐1@Mn‐N‐C Catalyst

Advanced Science, EarlyView.
Core–shell interface of TS‐1@Mn‐N‐C enables in situ generation of high‐concentration H2O2 and its spatially confined activation toward epoxidation‐active η‐Ti‐OOH species, leading to highly efficient and continuous electrochemical epoxidation. The work successfully addresses the key challenge of inefficient mass transfer and slow kinetics caused by ...

Controlled Atom Transfer Radical Depolymerization

Advanced Science, EarlyView.
Controlled atom transfer radical depolymerization allows for precise, uniform shortening of polymer chains to yield monomers on demand. By tuning catalyst concentration and temperature, this strategy prioritizes deactivation to maintain molecular weight control throughout depolymerization.
