College of Science
University of Idaho
Professor

With UI Since 1969


  • Research/Focus Areas
    • Supercritical fluid extraction of metals and radionuclides, green techniques for nuclear waste management, nanomaterials synthesis and catalysis, supercritical fluid reactions and nanoparticles deposition
  • Biography
    Chien Wai received his Ph.D. degree in Chemistry from the University of California, Irvine, in 1967 under the guidance of Professor F. Sherwood Rowland.  After two years of post-doctoral study at UCLA, he joined the chemistry faculty at the University of Idaho in 1969.  He has been teaching and doing research at the University of Idaho for 40 years.  In the past four decades, Wai has mentored 40 Ph.D. students and 30 M.S. students in chemistry at the University of Idaho.  He has also published 270 research papers and received 15 U.S. patents.

  • Research Projects
    • Developing green extraction techniques for nuclear waste management with the nuclear industry
    • British Nuclear Fuel plc. 1995-1998; Areva 2004-2010
    • Areva has licensed Wai's supercritical fluid extraction technology from the University of Idaho for industrial recovery of enriched uranium from wasted generated by a nuclear fuel fabrication process.  This is the first industrial demonstration of UI's supercritical fluid technology for nuclear waste management.
