An efficient flamelet progress-variable method for modeling non-premixed flames in weak electric fields

open access: yes, 2017
Combustion stabilization and enhancement of the flammability limits are mandatory objectives to improve nowadays combustion chambers. At this purpose, the use of an electric field in the flame region provides a solution which is, at the same time, easy ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

open access: yesAdvanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Polar Lattice‐Distorted Motifs Enable Synergy of Local Polarization/Dipole Fields for Concurrent Glyphosate Wastewater Remediation and CO Evolution

open access: yesAdvanced Science, EarlyView.
Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Stability of a premixed flame in stagnation-point flow against general disturbances [PDF]

open access: yes
Previously, the stability of a premixed flame in a stagnation flow was discussed for a restricted class of disturbances that are self-similar to the basic undisturbed flow; thus, flame fronts with corrugations only in the cross stream direction were ...

The BnTFL1‐BnJAM3‐BnSWEETs Module Orchestrates Seed Storage Reserve Accumulation in Brassica napus

open access: yesAdvanced Science, EarlyView.
BnaC03.TFL1 and BnaA01.JAM3 form a complex that facilitates the transport of soluble sugars from the seed coat to the embryo by directly activating the expression of BnSWEETs. Furthermore, BnaC03.TFL1 and BnaA01.JAM3 work cooperatively to promote soluble sugar and oil production while suppressing protein deposition.

Non-premixed Flame-Turbulence Interaction in Compressible Turbulent Flow [PDF]

open access: yes, 2002
Nonpremixed turbulent reacting flows are intrinsically difficult to model due to the strong coupling between turbulent motions and reaction. The large amount of heat released by a typical hydrocarbon flame leads to significant modifications of the ...

In Situ Electrochemical Activation of Pseudo‐Layered NbS3 via Interlayer Expansion and Dual Redox for High Mg‐Ion Storage

open access: yesAdvanced Science, EarlyView.
A quasi‐1D pseudo‐layered NbS3 cathode for magnesium‐ion batteries can be created through electrochemically induced interlayer expansion. The widened ion‐transport channels enable fast magnesium ion diffusion and unlock coupled cationic‐anionic redox chemistry.
