Auto-Ignition and Flame Stabilization of Hydrogen / Natural Gas / Nitrogen Jets in a Vitiated Cross-Flow at Elevated Pressure [PDF]
, 2013 The influence of natural gas (NG) on the auto-ignition behavior of hydrogen (H2)/nitrogen (N2) fuel jets injected into a vitiated cross-flow was studied at conditions relevant for practical combustion systems (p = 15 bar, Tcross-flow = 1173 K).

Fire-Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual-Functional Microcapsules for Lithium Metal Batteries. [PDF]
Adv Sci (Weinh)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 ...
