Pyrrolo sulfonamide compounds for modulation of orphan nuclear receptor RAR-related orphan receptor-gamma (RORgamma, NR1F3) activity and for the treatment of chronic inflammatory and autoimmune diseases
The decay of NH2 radicals, from 193 nm photolysis of NH3, was monitored by 597.7 nm laser-induced fluorescence. Room-temperature rate constants of (1.21 ± 0.14) × 10−10, (1.81 ± 0.12) × 10−11, and (2.11 ± 0.18) × 10−11 cm3 molecule−1 s−1 were obtained for the reactions of NH2 with N, NO and NO2, respectively. The production of NH in the reaction of NH2 with N was observed by laser-induced fluorescence

The Significance of Lewis Acid Sites for the Selective Catalytic Reduction of Nitric Oxide on Vanadium‐Based Catalysts
mechanisms of the selectivecatalyticreduction (SCR) of nitricoxide with ammonia (NH3) on vanadium‐based catalysts rely on the involvement of Brønsted or Lewis acid sites. This issue has been clearly elucidated using a combination of transient perturbations of the catalyst environment with operando time‐resolved spectroscopy to obtain unique molecular level insights. Nitricoxide reacts predominantly
