Last night's almost full moon. This is how it might look if you could boost the colour sensitivity of your eyes.
The different colours are present because of the way different minerals on the surface of the moon scatter sunlight to different degrees.
@sciencebase Relate thing: Do you know why wavelength dispersive analysis works with low atomic number elements like C and O, but energy disp doesn't (as in what we get in an SEM)? Grateful for ant ref you have about it.
@sciencebase You can get WDS on the SEM now, I'm told. Helpful for oxide inclusions in the steel as it avoids having to dissolve the lot and use XRD on what's left.
@sciencebase Using cation analysis and assuming the usual oxide types are there is limited cos their melting point is often important.
@SteelFolk WDS is higher resolution
@SteelFolk Is it to do with their energies being less widely spaced than heavier elements? So harder to distinguish with the resolution of current technology?
