    • The use of large gradient pulses in diffusion-ordered 2D NMR spectroscopy (DOSY) results in the induction of eddy currents in the metal structures of the magnet and probe, which causes a distortion in the high-resolution spectra. The LEDbp sequence reduces that problem by using bipolar pulse pairs, since the eddy currents caused by two gradient pulses with identical areas, but different polarities tend to cancel

    • Simulations using a dodecahedron (12 faces) or icosahedron (20 faces) gave essentially identical results (data not shown). This indicates that, at least from a theoretical point of view, the polydispersity of the nanoparticles is less relevant. This originates from the fact that the catalytic site is composed of only 12 units, which is far less than the total number of thiols present in the monolayer. Experimentally, polydispersity may cause a different spacing between two catalytic units, resulting in different efficiency. However, the similarity of the catalytic parameters of the nanoparticles presented here ((1.6±0.2)nm) and those of a previous study ((2.5±0.7)nm, ref.[15]) indicate that polydispersity does not appear to play an important role. For that reason, and also considering the relative narrow size distribution of the nanoparticles here, polydispersity was not taken into account in the analysis
