| 20080213584 | 2-OCTYL (METH)ACRYLATE ADHESIVE COMPOSITION - A pressure sensitive adhesive composition comprising a 2-octyl (meth)acrylate/(meth)acrylic acid copolymer is described.

| 20090011293 | Selective Oxidation of Carbon Monoxide Relative to Hydrogen Using Catalytically Active Gold - The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate, crystalline titania. In some aspects of practice, the surface of nanoparticulate media incorporated into a catalyst system of the present invention is provided with chemical modifications of the surface that dramatically suppress the ability of the resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO. In other words, by selecting and/or altering the nanoparticulate surface via the principles of the present invention, PROX catalysts are readily made from materials including catalytically active gold and nanoparticulate media. Additionally, the nanoparticulate support also may be optionally thermally treated to further enhance selectivity for CO oxidation with respect to hydrogen. Such thermal treatments may occur before or after chemical modification, but desirably occur prior to depositing catalytically active gold onto the support incorporating the nanoparticles. | 01-08-2009 |

The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices. | 03-05-2009 |
| 20090145458 | SOLID CLEANERS FOR HEATED FOOD PREPARATION SURFACES - A solid cleaner for heated surfaces is disclosed. The solid cleaner includes a solidifying agent including wax, and a cleaning agent. The solid cleaner is solid at room temperature and liquid at an elevated temperature.

| 20090326498 | HYDROPHILIC GEL FROM REACTIVE HYDROPHILIC OLIGOMERS - Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing photoinitiator groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices. | 12-31-2009 |
| 20100047142 | FILTER MEDIA INCLUDING FILTERING AGENT EFFECTIVE FOR REMOVAL OF CYANO-CONTAINING CONTAMINANTS HAVING IMPROVED COMPATIBILITY WITH AMINE SENSITIVE IMPREGNANTS AND AMINE SENSITIVE SUBSTRATES - Filter media containing an impregnant obtained by pre-reacting an amine functional material with a transition metal to form an amine-metal coordination complex. The complexed amine is much more compatible with amine sensitive co-impregnants or amine sensitive substrates. Additionally, even though the amine is complexed, the impregnant retains high activity for the removal of cyano-containing vapors and other contaminants for which amines have a filtering efficacy. Advantageously, therefore, the filter media may be used to remove cyano-containing vapors or other amine-targeted contaminants from air and other harmful gases in the presence of metal-based catalysts (such as those catalysts comprising platinum, gold or other active transition metals) without the undesirable effect of unduly inhibiting or poisoning the metal-based catalysts. The amine-containing coordination complex is also more compatible with substrates having electret characteristics as compared to otherwise identical amine material that is not complexed. | 02-25-2010 |
| 20100076169 | AZLACTONE TELECHELIC POLYMER - A curable composition is described comprising a Michael donor component, a polyacryl component, and 1) an ethylenically unsaturated monomer having a reactive azlactone functional group, or 2) an ethylenically unsaturated monomer having a reactive ring-opened azlactone functional group. A telechelic polymer that is the reaction product of these components is also described. | 03-25-2010 |
| 20100240799 | ANTIMICROBIAL FILM-FORMING COMPOSITION, ANTIMICROBIAL FILM, AND METHOD OF VERIFYING THE PRESENCE OF AN ANTIMICROBIAL FILM - An antimicrobial film-forming composition, an antimicrobial film, and a method of verifying the presence of an antimicrobial film. The film-forming composition can include no greater than 10 weight percent of polyvinyl alcohol, from 0.05 to 15 weight percent of polyhexamethylene biguanide, from 0.001 to 10 weight percent of a quaternary ammonium compound, and water or a water-based solvent. The film-forming composition can form a water-soluble, biocidal antimicrobial film that includes no greater than 98 weight percent of polyvinyl alcohol, and from 1 to 15 weight percent of each of polyhexamethylene biguanide and the quaternary ammonium compound. The method can include applying a film-forming composition comprising an indicator dye to a surface, drying the film-forming composition to form an antimicrobial film, and triggering the antimicrobial film to trigger the indicator dye to verify the presence of the film. | 09-23-2010 |
| 20100273091 | Catalytically Active Gold Supported On Thermally Treated Nanoporous Supports - The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate titania. It has been discovered that the nature of the surfaces of the nanoparticles used to support a nano-metal catalyst, such as catalytically active gold, has a profound effect upon the catalytic properties of the supported catalyst. The support surface may be altered as desired to control the activity of the gold. The present invention teaches how thermal treatment of nanoparticulate media incorporated into a nanoporous support prior to deposition of catalytically active gold dramatically suppresses the ability of a resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO. | 10-28-2010 |
