The School of Engineering and Applied Science has just published a feature on the links between art and science called "Art Form Function" that can be found here: http://www.princeton.edu/engineering/art/story-01/
It includes a section describing the work of Sonia Naidu on protection of marble by coatings of hydroxyapatite (http://www.princeton.edu/engineering/art/story-06/) and an example of one of her beautiful SEM photos (http://www.princeton.edu/engineering/art/story-14/).
