Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Role of pocket formation in the extinction of methane flames subject to strong turbulence
Applications in Energy and Combustion ScienceDespite extensive studies of local and global extinction, it remains unclear how local flame dynamics contribute to the global evolution of a turbulent flame at large Karlovitz numbers. Furthermore, the extent to which canonical laminar flame properties,

Simultaneous measurements of flame geometry and flow field by OH-PLIF/Stereo PIV
Nihon Kikai Gakkai ronbunshu, 2016 It is difficult to understand turbulent combustion, because the combustion process is very complex and unsteady. One of the useful parameters for discussion of the unsteady flame behaviors is the flame stretch rate, which is evaluated by local flame ...

Flame-driven deflagration-to-detonation transitions in Type Ia supernovae?
, 2007 Although delayed detonation models of thermonuclear explosions of white dwarfs seem promising for reproducing Type Ia supernovae, the transition of the flame propagation mode from subsonic deflagration to supersonic detonation remains hypothetical.

Variation of turbulent burning rate of methane, methanol, and iso-octane air mixtures with equivalence ratio at elevated pressure [PDF]
, 2005 Turbulent burning velocities for premixed methane, methanol, and iso-octane/air mixtures have been experimentally determined for an rms turbulent velocity of 2 m/s and pressure of 0.5 MPa for a wide range of equivalence ratios. Turbulent burning velocity

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons
Advanced Materials, EarlyView.Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Effect of Stretch on Local Burning Velocity of Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2007 The effect of positive stretch on the local flame properties of turbulent propagating flames in the flamelet regime was investigated experimentally for methane-, hydrogen- and propane-air mixtures with lean and rich having nearly the same laminar burning

Modelling turbulent premixed combustion in the intermediate steady propagation regime [PDF]
, 1999 Numerical simulation and comparison with standard experimental data of turbulent premixed combustion occurring at large Reynolds and moderately large Damkohler numbers (a situation which is typical in industrial burners) have been presented.

Propagation of the First Flames in Type Ia Supernovae [PDF]
, 2006 We consider the competition of the different physical processes that can affect the evolution of a flame bubble in a Type Ia supernovae -- burning, turbulence and buoyancy.
