Extended Data Fig. 5: Beam flux effect on surface species.
From: Operando probing of the surface chemistry during the Haber–Bosch process
a, The trend of N1s intensity over Ru at 500 mbar, 423 K, 1:3 N2:H2 gas ratio as beam flux increased, with a line of best fit in grey (intercept set to zero) showing that the beam does not have an appreciable effect on total coverage. b, The same experiment showing that the N1s spectra gathered sequentially from lowest flux to full flux, showing no change in speciation with beam flux.
