Influence of Turbulent Scalar Mixing Physics on Premixed Flame Propagation

Journal of Combustion, 2011
The influence of reactive scalar mixing physics on turbulent premixed flame propagation is studied, within the framework of turbulent flame speed modelling, by comparing predictive ability of two algebraic flame speed models: one that ...

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,

Design of a Novel Diamine Biosensor to Guide the Engineering of Escherichia coli for Cadaverine Overproduction

Advanced Science, EarlyView.
A high‐throughput screening platform was established by integrating an in vivo cadaverine biosensor with a fluorescence‐activated cell sorting (FACS) system. Biosensor‐driven specific exporter tuning, pathway optimization and genome‐wide target mining were conducted to maximize cadaverine production in Escherichia coli.

Simulations of combustion roar in turbulent attached and lifted turbulent methane jet flames

Engineering Transactions, 2014
The present work presents sample results of preliminary computations of the turbulent aerothermodynamic flow field and of the noise generated by the flame front, due to turbulent fluctuations in the flame (combustion roar), in lifted and attached jet ...

Timescales Associated with the Evolution of Reactive Scalar Gradient in Premixed Turbulent Combustion: A Direct Numerical Simulation Analysis

Fire
The fractional change in the reaction progress variable gradient depends on the flow normal straining within the flame and also upon the corresponding normal gradients of the reaction rate and its molecular diffusion transport. The statistical behaviours

Atomically Dispersed Fe‐Modified SnS for Sn‐Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation

Advanced Science, EarlyView.
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the

Fire‐Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual‐Functional Microcapsules for Lithium Metal Batteries

Advanced Science, EarlyView.
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

Triple‐Coupling Regulation Enables Dendrite‐Free Subzero Aqueous Zn‐Ion Batteries

Advanced Science, EarlyView.
A formamide‐ethanol deep eutectic electrolyte enables triple‐coupling regulation of solvation structure, interfacial chemistry, and crystallographic Zn deposition. The reconstructed Zn2+ solvation reduces water activity and suppresses side reactions, while a robust hybrid SEI stabilizes the interface.
