Biography:

Professor Rick Laine is a faculty member in both Materials Science and Eng. and Macromolecular Science and Eng. at the University of Michigan. He received his B. S. in chemistry at Cal. State University Northridge followed by a Ph.D. at the University of Southern California. After several post-docs, he spent 11 years at Stanford Research Institute (SRI International) followed by three years in MSE at the University of Washington before coming to UM. His research interests include novel ceramic processing methods and the development of silicon containing polymers for electronic and photonic applications. He has >300 publications, 45 patents and H factor of 72.

Abstract:

We present here a very simple, low-temperature approach to the syntheses of single, and bime-tallic nitride precursors and thereafter their respective nitrides wherein metal-nitrogen bond for-mation is driven by formation of Si-O bonds. The resulting single and bi-metallic nitride precursors are for the most part fully soluble even as complex mixtures and on mild heating in an inert atmos-phere transform to their respective nitrides at temperatures of ≥400℃. Example syntheses include the single metal nitrides CoNx, FeNx, MgN, MnN, YN, bimetallic magnetic nitride materials in-cluding FeCoNx, FeNiNx and CoNiNx.
