Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

The dilution of gaseous products obtained at high‐current densities during CO2 electroreduction or water electrolysis enables their accurate quantification via online gas chromatography, which is crucial for reliable catalyst benchmarking. The corresponding Faradaic efficiencies can then be calculated with low deviations using two different instruments,

Influence of the Wall Heat Transfer on Flame Propagation [PDF]
In the internal combustion engines, the flames interact with the walls of the cylinder, which affects the flame propagation characteristics and the engine performance. The flame tends to quench near the wall, which is due to wall heat fluxes.

Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride
Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...
