A technique for coating small three-dimensional objects with zeolite molecular sieves using pulsed laser deposition (PLD) has been developed. Oriented zeolite UTD-1 films have been deposited on the surface of ∼0.5 mm galvanized steel spheres by vibrating the beads in the plume followed by a hydrothermal treatment. The resulting UTD-1 film is well-adhered and composed of planklike crystals oriented so that the one-dimensional channels are normal to the substrate surface.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
