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 ...

Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

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.

An Experimental Investigation on the Combustion and Heat Release Characteristics of an Opposed-Piston Folded-Cranktrain Diesel Engine

Energies, 2015
In opposed-piston folded-cranktrain diesel engines, the relative movement rules of opposed-pistons, combustion chamber components and injector position are different from those of conventional diesel engines.

Multi‐Phase Heterostructured NiMoN Nanoflower as Bifunctional Separator Coatings for High‐Performance Lithium–Sulfur Batteries

Battery Energy, Volume 5, Issue 5, September 2026.
NiMoN nanoflowers are introduced as multifunctional separator coatings for Li–S batteries. The dual‐metal nitride structure offers strong polysulfide adsorption, accelerated redox kinetics, and enhanced Li+ transport. Compared to NiN and Celgard, NiMoN achieves superior cycling stability, lower capacity fading, and excellent rate performance ...

Thermal Degradation of PFAS in Different Scales: Measurement of Hydrogen Fluoride (HF)

Chemie Ingenieur Technik, Volume 98, Issue 9, Page 600-606, September 2026.
The communication article is about the challenges to balance a combustor in the case of fluorine when incinerating PFAS containing materials. Several analytical methods are compared: for continuous measurement, FTIR with TDLS. The detected fluorine species are further compared with results upon IC and pyrohydrolysis for discontinuous measurements in ...
