Influence of Annular Flow Area and a 30-Degree Impingement Angle on Methane/Oxygen Diffusion Flame Stability

Methane
This work examined the effects of secondary annular flow area on flame stability in an experimental diffusion flame burner. The burner was composed of a horizontally mounted, rectangular chamber that utilized a retractable spark plug for ignition and an ...

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

Advanced 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

Numerical investigation of the Soret effect on burning velocity of lean hydrogen flame

Journal of Thermal Science and Technology
2D numerical simulations of a wrinkled lean hydrogen (H2)-air premixed flame are performed with and without considering the Soret effect to investigate the Soret effect on flame propagation.

Measurement of PAH and soot of diffusion flames in a triple port burner [PDF]

, 2013
In this study, we measured PAH and soot in a triple port burner. The coannular burner consists of three concentric tubes, where air flows in both inner (central) and outer tubes, and fuel flows in the annulus between these air tubes. Two diffusion flames

Highly Flexible and Conformable ZnO/FeGa Magnetoelectric Heterostructures for Skin wound Healing

Advanced Science, EarlyView.
The magnetic field‐induced electric field generated by a highly flexile ZnO(piezoelectric)/FeGa(magnetostrictive) magnetoelectric heterostructure embedded in the low Young's modulus elastomer PDMS has been used to stimulate the wound healing processes.

Blending effect between the natural gas and the liquefied petroleum gas using multiple co- and cross-flow jets on NOx emissions

Ain Shams Engineering Journal, 2019
A burner comprising multiple co- and cross-flow jets was developed to address the effect of blending the natural gas (NG) with the liquefied petroleum gas (LPG) on the NOx emissions from laminar/turbulent diffusion and triple flames in the normal and ...

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide

Advanced Science, EarlyView.
Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.
