Will Carden, a graduate student in the McElwee-White lab at the University of Florida, designs gold (I) precursors for focused electron beam induced deposition (FEBID), a technique that uses an electron beam to blast apart gaseous molecules so that resulting nonvolatile fragments deposit on a substrate. One afternoon, he sublimated t-butylisocyanide gold(I) chloride to produce a wealth of white needle-like crystals that predominately collected on a chilled piece of glassware called a cold-finger. But some of the crystals also grew out of the bottom of the flask. The green residue is likely a product of decomposition, Carden says, but it creates a garden-like setting for the crystalline tree in the center.
