If you only have plastic wheels on the track, then I would assume you wouldn't get the gunk. Unfortunately, that means you don't have an engine, or other cars with metal wheels, and thus you are stuck on your tracks with no motive power, and gunk wouldn't be produced. I assume that the Ni gives the largest signal with the spectrograph, and thus carbon and othercomponents of the gunk wouldn't show as strong a signal. It is interesting that Ni(III) is the oxidation state since Ni(II) is the most common (and possibly Ni(0) with the carbonyls). talley-ho Rance Velapoldi (Tranby, Norway) if this sounds a little flip, it is because I am almost finished with my second Margarita - maybe I should read emails after 2-3 so that answers might be a little more humorous???
