  • Metalworking lubricant formulations based on supercritical carbon dioxide
    Patent number: 8167092
    Abstract: A method for lubricating a metal workpiece during a metalworking process includes delivering supercritical carbon dioxide to the workpiece during the metalworking process. The supercritical carbon dioxide acts as a lubricant, coolant, chip evacuator, and/or carrier for another lubricant or corrosion inhibitor.
    Type: Grant
    Filed: August 1, 2008
    Date of Patent: May 1, 2012
    Assignee: The Regents of The University of Michigan
    Inventors: Steven J. Skerlos, Kim F. Hayes, Andres F. Clarens
  • SYSTEM AND METHOD FOR SIMULTANEOUS BIOLOGICALLY MEDIATED REMOVAL OF CONTAMINANTS FROM CONTAMINATED WATER
    Publication number: 20110017663
    Abstract: A system and method for simultaneous biologically mediated removal of contaminants (including at least arsenic or nitrate) from water are disclosed herein. The system includes i) a bioreactor having a length suitable for housing at least three different microbial populations, or ii) two bioreactors coupled together, the two bioreactors each having a length and an empty bed contact time that together are suitable for housing at least three different microbial populations. The system also includes a biofilm attachment medium positioned in i) the bioreactor, or ii) the two bioreactors; and the at least three different microbial populations formed on the biofilm attachment medium. The microbial populations are selected from oxygen reducing microbes, nitrate reducing microbes, arsenate reducing microbes, sulfate reducing microbes, and uranium reducing microbes.
