Flame wrinkling factor in quiescent hydrogen-air mixtures [PDF]

When modelling the combustion of hydrogen in such a large domain as a nuclear reactor containment building, flame wrinkling needs be quantified in the changing conditions of the combustion process.

Decoding α‐MoC1−x Nanoparticle Formation in Continuous Flow via Machine Learning

Small, EarlyView.
Formation pathway of α‐MoC1−x nanoparticles synthesized from oleylamine‐Mo(CO)6 precursor under mild continuous‐flow conditions was investigated. By combining in‐line spectroscopic monitoring with a machine learning (ML) framework capable of deconvoluting complex, overlapping spectral features, we reveal mechanistic details of early‐transition‐metal ...

3D flame surface curvature analysis from reconstructed scanning across spherical expanding flames

Proceedings of the Combustion Institute
We analyze 3D reconstructed surfaces based on previously reported high frequency measurements of flame edge location across expanding flames using Mie scatter. For the first time, principal curvatures of flame surfaces are estimated from eigenvalues of the second fundamental forms of the reconstructed surfaces, allowing the determination of the ...

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

Small, EarlyView.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...

Oxide Scale Morphology of Carbon Steels Under Novel Reheating Conditions

steel research international, EarlyView.
This study focuses on the changes in oxide scale morphology formed under simulated hydrogen and oxy‐fuel reheating gas atmospheres in comparison to natural gas‐air reheating. Several different properties were analyzed, such as pore structure, ratios of iron oxides, adhesion, and distribution of alloying elements.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
