Quantum Dot Array Formation through Biomolecular Nanopatterning

Not Available Microwave NDE methods show promise in detecting corrosion under coatings, but have failed to demonstrate the senstivity to detect onset levels of corrosion, a requirement for aircraft inspection. To improve microwave NDE senstivity SMRC proposes to modify aircraft coatings, both paint and appliques, to reduce microwave return energy in the bands containng aluminum corrosion products. This coating-microwave interaction (C/MI) NDE innovation should improve microwave senstitivy to onset corrosion levels in aluminum, as demonstrated in similar tests at Sandia Labs using millimeter waves. Phase I paint modifications will include pigment re-blending using low microwave return constituents identified through materials characterization. Appliques provided by 3M Corporation will be tested in a variety of thickness and colors, and guidance for modifications will be developed via microwave characterization of applique base materials and pigments. Boeing's Electromagnetic Properties Laboratory will characterize coating materials and constituents, and conduct sensitivity testing of Phase I coated aluminum panels. Focused microwave NDE methods used at Boeing for aircraft windshield NDE will be explored for enhancing C/MI corrosion sensitivity. Coated corroded specimens will be prepared at Southwest Texas State University. Phase I includes a full C/MI NDE Navy cost model and commercialization planning for both DoD and commercial air NDE product introductions.
