The effect of hydrogen addition to lean counterflow CH4/air premixed flames on the extinction limits and the characteristics of NOx emission was investigated by numerical simulation. The detailed chemistry and complex thermal and transport properties were employed. The results show that the addition of hydrogen can significantly enlarge the flammable region and extend the flammability limit to ...

The formation of hydrogen bonds was investigated on the P-rich InP 001 surface employing attenuated total-reflection Fourier-transform infrared spectroscopy, low-energy electron diffraction, and total-energy density-functional theory calculations. Strong evidence was found for a c 2 2 -2P-3H reconstruction with a higher hydrogen coverage than is characteristic for the metal-organic chemical-vap...
