Coupled thermoacoustic interactions in hydrogen-enriched lean combustion

Experiments in Fluids
In this paper, we present a framework to study the synchronization of flow velocity with acoustic pressure and heat-release rate in technically-premixed swirl flames. The framework uses the extended proper orthogonal decomposition to identify regions of the velocity field where velocity and heat release fluctuations are highly correlated. We apply this

Powder‐to‐Film Conversion of Nickel Single‐Atom Catalysts into Binder‐Free and Resistant Electrodes

Advanced Materials Interfaces, EarlyView.
A reproducible strategy is reported for fabricating standalone thin‐film electrodes composed of CNx‐supported Ni single‐atom catalysts. The resulting binder‐free electrodes exhibit robust stability, enhanced charge transfer, and superior electrochemical performance, offering scalable opportunities for applications in electrochemistry. ABSTRACT Although

Spin‐Crossover Confinement in Mesoporous Matrices Enables Tunable Porosity for Molecular Sensing

Advanced Materials Interfaces, EarlyView.
The integration of hierarchically organized porous frameworks with spin‐crossover nanodomains enables cooperative interactions across multiple length scales. This hybrid design merges dynamic molecular switching with tunable porosity, yielding materials whose structural and functional responses are actively modulated by confinement and guest uptake ...
