| 20100010261 | PRODUCTION OF AMINES - A process for the hydrogenation of carboxylic acids and/or derivatives, particularly amides, is described. The process includes reacting an acid or derivative such as an amide with a source of hydrogen in the presence of a catalyst system. The catalyst system obtainable by combining: (a) a source of ruthenium, and (b) a phosphine compound of general Formula I: (Formula I). The hydrogenation reaction is carried out in the presence of a low concentration of water or at low pressure or in the presence of a source of ammonia or the hydrogenation reaction is carried out in the absence of water or a combination of these factors is utilised. The invention also relates to the use of ammonia in the production of primary amines by hydrogenation of carboxylic acids and/or derivatives thereof or a process for the production of primary amines generally. | 01-14-2010 |

| 20090318734 | IONIC ADDITIVE FOR CATALYSIS IN BIPHASIC REACTION SYSTEMS - An additive for improving the rate of catalysis in biphasic reaction systems is disclosed. The additive is an ionic molecule comprising an organic cation such as a heterocyclic compound or a quaternary ammonium or phosphonium cation, and an anion which may be organic or inorganic. A process for improved catalysis in an aqueous biphasic system wherein the catalyst is substantially dissolved in the aqueous phase and the substrate is substantially contained in the non-aqueous phase is also described. A suitable additive is 1-octyl-3-methylimidazolium halide. Examples of suitable catalytic reactions include the hydrogenation, hydrosilation, hydroboration, hydrovinylation, hydroformylation, oxidation and hydroxycarbonylation of alkenes, and Heck, Suzuki, Stille, and Sonigashira coupling. | 12-24-2009 |

| 20110104815 | CONJUGATED NANOPARTICLES AND THEIR USE IN DETECTION OF LATENT FINGERPRINTS - Novel conjugates of nanoparticles are provided and have particular utility in the detection of latent fingerprints by their ability to bind to a fingerprint residue. The conjugate comprises a nanoparticle attached to a linker group having a terminal reactive moiety, wherein said nanoparticle comprises a core of a first semiconductor material having a first luminescence and a shell of a second material which at least partially surrounds the core. The conjugated nanoparticle can bind to the fingerprint residue and can be detected using fluorescence. | 05-05-2011 |
