| 20100206134 | METHOD FOR RECOVERY - A method is provided for recovering metals from a spent catalyst composition containing an organic contaminant and catalytically active metals on a catalyst support. The metals are leached from the spent catalyst composition by adding under stirring an ionic liquid. The ionic liquid containing the leached metals is separated from the organic contaminant and the catalyst support by adding under stirring an anti-solvent. After removing the organic contaminant and the catalyst support, the leached metals are separated from the ionic liquid for example by selective precipitation, ion exchange, solvent extraction, electrodeposition, chromatographic, or pyrometallurgical methods. | 08-19-2010 |

| 20100171065 | MAGNETORHEOLOGICAL MATERIALS, METHOD FOR MAKING, AND APPLICATIONS THEREOF - A magnetorheological material comprises a magnetic particle and a ceramic material, wherein the magnetorheological material is in a dried form and further wherein a portion of the ceramic material is in the form of a nanocrystalline coating over the entire exterior surface of the magnetic particle and another portion of the ceramic material is in the form of a free nanocrystal. A magnetorheological material comprises a magnetic particle having a ceramic material coating over an external surface thereof as a result of a coating process, and a free nanocrystal of the ceramic material in the form of a residual by-product of the coating process. A sol-gel process for making a magnetorheological product comprises providing a sol of a desired ceramic coating material; combining a desired quantity of carbonyl iron (CI) particles with the sol to coat the CI particles with the ceramic coating material; creating a resulting quantity of nanocrystalline ceramic material-coated CI particles and a quantity of free nanocrystals of the ceramic material; and, drying the resulting quantity of coated CI particles and free nanocrystals to a moisture content equal to or less than 2 wt %. | 07-08-2010 |
