Delaina Amos

Assoc Professor

Delaina Amos received a BS in Chemical Engineering from the University of Virginia in 1989. She later obtained a MS and PhD in Chemical Engineering from the University of California Berkley in 1992 and 1996 where she was both a GEM MS fellow and among the first class of GEM Engineering PhD Fellows. After completing a one-year industrial post-doctoral assignment at Eastman Kodak, Dr. Amos joined the research staff at Eastman Kodak in 1997. Dr. Amos held a variety of roles at Kodak including research scientist, R&D team leader, technical liaison, and intellectual property co-leader. While at Kodak, work that she was involved in went into creating the new platform of pigment-based inks for the Kodak consumer printer lines. Dr. Amos joined the faculty of the Department of Chemical Engineering at the University of Louisville in June 2010 as an Associate Professor. Dr. Amos' research interests involve novel uses of colloidal materials, quantum dots, polyelectrolytes, inkjet materials and thin film deposition for renewable energy and display applications such as solid-state lighting, solar cells, nanofermentation and color writable electronic displays. Her work sits at the interface of novel applications of these materials to create energy, color and light.

Solution Phase Synthesis and Intense Pulsed Light Sintering and Reduction of a Copper Oxide Ink with an Encapsulating Nickel Oxide Barrier- 2015

Copper nanoparticle inks sintered by intense pulsed light are an inexpensive means to produce conductive patterns on a number of substrates; however, oxidation and diffusion characteristics of copper are issues to be resolved. Nickel can provide a degree of oxidation protection and act as a barrier diffusion layer. In this study we produce nanoparticles of copper with a nickel sheel using a solution phase synthesis run at room temperatures. These dispersions are then directly deposited onto a substrate and sintered using an intense pulsed light source. The core-shell nanoparticles and resulting films are characterized using electron microscopy and x-ray spectroscopy and the conductivity measured using a four point probe resistivity. The synthesis results in a simple technique with highly controllable shell thickness on a 20 nm copper nanoparticle. The sintering technique produces a highly conductive film with very short processing times.
