A method is disclosed for curing ink printed images on golf balls by printing an image onto a golf ball and exposing the printed image to infrared radiation, then exposing the printed image to ultraviolet radiation. In a preferred embodiment, the ATM includes means for entering a key component and an ATM processor board, and the apparatus includes a microprocessor and a persistent, non-volatile memory device electrically disposed between the key component entry means and the ATM processor board. The dimensions, geometry, and location of the shielding plate are optimized to generate a desired ion flux in a plasma-assisted material process conducted in a plasma chamber. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation of aerogel structures. The polydentate ligand stabilizes the nanocrystal.
