Engineering Phosphorus‐Modified Flame‐Retardant Thermoplastic Polyurethane via Reactive Melt Processing

Journal of Polymer Science, EarlyView.
Phosphorus‐modified TPUs are prepared by one‐step, solvent‐free reactive melt processing using phosphate‐ or phosphonate‐containing diols and PEG or PPG soft segments. Fire behavior and mechanical response depend strongly on both chemistries. Peak heat release rate decreases by up to 54%, but reduced tensile strength and V‐2 dripping behavior reveal a ...

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced

The Importance of Thermodynamic Data for Pyrrole Pyrolysis and Combustion Chemistry

ChemPhysChem, Volume 27, Issue 18, 28 September 2026.
High level ab initio quantum chemical computations with ORCA 6.1.1 are done to derive enthalpy and entropy of formation at 298.15 K for 32 species that include both radicals and stable molecules relevant to the pyrolysis and combustion of pyrrole. The effects of thermochemical data on chemical model performance are assessed.
