The effect of the adsorbate mass on an Eley-Rideal (ER) reaction is examined for the reactive ion scattering (RIS) of Cs+ from physisorbed adsorbates (Ar, Kr, Xe and N2) on a Ru(0001) surface at hyperthermal energy (10-60 eV). The measurement of the RIS cross-section, or the efficiency for ER-type abstraction of surface adsorbates, reveals an inverse proportionality between the square root of the cross-section and the mass of the noble gases. This relationship is explained by the inertia effect which can determine the probability of successful abstraction events of the adsorbates.

Hydroxyl, epoxide, carboxyl, and some alkyl functional groups are present in the GO, as identified by solid-state 13C NMR, Fourier-transform infrared spectroscopy, and X-ray photoemission spectroscopy. Starting with pyrolytic graphite (interlayer separation 3.
