Correlation of flame speed with stretch in turbulent premixed methane/air flames [PDF]

Symposium (International) on Combustion, 1998
Direct numerical simulations of two-dimensional unsteady premixed methane/air flames are performed to determine the correlation of flame speed with stretch over a wide range of curvatures and strain rates generated by intense two-dimensional turbulence.

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain
