Patent Number Title Of Patent Date Issued
8225641 Nanofibers and methods of making same and using same in humidity sensors July 24, 2012
A self-cleaning humidity sensor based on Mg.sup.2+/Na.sup.+-doped TiO.sub.2 nanofiber mats is provided. Examples show the response and recovery characteristic curves for ten circles with the RH changing from 11% to 95%. The nanofibers are manufactured by mixing together a metal salt
8133637 Fuel cells and fuel cell catalysts incorporating a nanoring support March 13, 2012
The fuel cells include electrode membrane assemblies having a nanoparticle catalyst supported on carbon nanorings. The carbon nanorings are formed from one or more carbon layers that form a wall that defines a generally annular nanostructure having a hole. The length of the nanoring
8097229 Methods for manufacturing functionalized inorganic oxides and polymers incorporating same January 17, 2012
Inorganic oxide substrates are functionalized with silicon-free organic functionalizing agents. The organic functionalizing agent has a bonding functional group for bonding to the substrate and a functionalizing moiety that is not bonded to the substrate for imparting a desired funct
7887771 Carbon nanorings manufactured from templating nanoparticles February 15, 2011
Methods for manufacturing carbon nanostructures include 1) forming intermediate carbon nanostructures by polymerizing a carbon precursor in the presence of templating nanoparticles, 2) carbonizing the intermediate carbon nanostructures to form an intermediate composite nanostructure,
7772154 Methods for making immobilized aryl-containing ligands August 10, 2010
Organic ligands that contain at least one aryl group are immobilized on a solid support. The organic ligands are of the type used to form a catalyst complex suitable for carrying out a catalytic reaction, preferably an asymmetric reaction. To immobilize the organic ligands, a tetheri
