WebApr 8, 2024 · In first order adsorption–desorption kinetics, ... (111) surface was prepared by three cycles of Ar+ ion sputtering at 1 keV (pressure 3.6 × 10 −6 Torr) followed by a flash annealing at 1600 K. After last cycle, the surface was exposed to 33 L of ethylene while keeping the sample at 1440 K. WebSep 8, 2003 · The (β + x)‐nitrogen structure was synthesized, so far as can be judged from its flash‐desorption spectrum, by dosing with pure nitrogen activated by electron bombardment. These results strongly suggest that the catalytic decomposition of ammonia on tungsten has as its limiting step the desorption of x‐nitrogen; ... god statue shop in parrys chennai
