    Patent number: 5418214
    Abstract: A new copper oxide superconductor of the formula Ln.sub.1-x M.sub.x Sr.sub.2 Cu.sub.3-y Ti.sub.y O.sub.7+.delta. is disclosed, and exhibits a Tc of 60.degree. K. with deviations from linear metallic behavior as high as 130.degree. K.
    Type: Grant
    Filed: August 23, 1993
    Date of Patent: May 23, 1995
    Assignee: Northwestern University
    Inventors: Robert Toreki, Kenneth Poeppelmeier, Bogdan Dabrowski
  • Homogeneous rhenium catalysts for metathesis of olefins
    Patent number: 5146033
    Abstract: The invention pertains to rhenium (VII) compounds which are catalysts for metathesis of ordinary olefins (hydrocarbons) and functionalized olefins in a homogeneous phase and to methods of synthesizing these compounds. The rhenium compounds comprise a rhenium (VII) atom centrally linked to an alkylidene ligand, an alkylidyne ligand, and two other ligands of which at least one ligand is sufficiently electron withdrawing to render the rhenium atom significantly active for metathesis.
    Type: Grant
    Filed: December 19, 1991
    Date of Patent: September 8, 1992
    Assignee: Massachusetts Institute of Technology
    Inventors: Richard R. Schrock, Robert Toreki
