STM image of Stage V, details and data related to nonlinear growth rate, details regarding growth rate vs nucleation rate calculations, and the effect of hydrogen cleaning; Figures S1 S3.
Nights out enjoying Christmas festivities have been quickly swapped for cleaning sessions, figuring out how to work without a laptop, and reeling out the same "thanks, at least I've got my health" speech to well-wishers on the phone.
Canadians figure cleaning up was included in the price and just leave all their shit there.
This can be therefore considered as the most likely source for the presence of wax in the superficial deposit and as single tiny drops over the stone material, although the presence of residual traces of an intentional waxing treatment cannot be excluded.The morphological characterization by ESEM-EDX of the stone surface before cleaning (sample S02, see Figure 1) is reported in Figure 3.
Several areas corresponding to the skin of some sculpted figures and objects (i.e., the hand and arm of an angel, the back of the donkey, the sack of S. Joseph) show a particularly smooth and reflective surface which has been defined as "polished surface".Optical microscopy and ESEM-EDX documentation of the stone substrate after cleaning (sample S02, see Figure 1) is reported in Figure 11.
Even in areas in which the removal is not complete (the partial residues areas), the sulphur content is significantly reduced to approximately 4 times less respect to the not cleaned reference area.Polished cross-sections observation reveals a good and homogeneous cleaning result (Figure 11C, D).
So under deceptively cheery blue skies, there was not much to do but to mourn, to begin cleaning out and to figure out what, if anything, would come next.
Specifically, it's a big data play that involves identification, matching, ordering and cleaning video data to figure out when, say, videos are buffering badly, or people are switching off streams in specific markets (to potentially begin to explain why), and in cases where there are advertisements, what is resonating and where, and what form that takes.
The size distributions of the crystallites formed are shown in Figure 2. As can be seen from these figures, the gold films formed crystallites with a typical size of 12 nm on substrates with native oxide after cleaning in neutral solution (Figure 2a).
