| 20140163248 | Heavy Metal Remediation Via Sulfur-Modified Bio-Oils - We have now discovered a novel process for the removal or extraction of metal species from a variety of solid, liquid or gas phase materials. Metal species may be removed by contacting the material suspected of containing one or more metals with a thiolated fatty acid or ester thereof for a period of time and under conditions effective for the sequestration of the metal species by the thiolated fatty acid or ester thereof. The thiolated fatty acid or ester thereof comprising sequestered metal species may then be separated and recovered from the treated material. Moreover, following the treatment of aqueous liquids or mixtures, or suspensions or dispersions of solids in aqueous liquids, the resultant thiolated fatty acid or ester thereof comprising the sequestered metal species is insoluble in water and forms a separate layer from the aqueous liquid phase, which layer may be readily removed. | 06-12-2014 |
| 20150291501 | METHODS OF METAL OXIDE NANOCRYSTALS PREPARATION - Embodiments relate to methods of metal oxide nanocrystals preparation. In embodiments, a metal-organic precursor may be economically synthesized by reacting a metal with an organic acid. The organic acid may include an aliphatic chain longer than three carbon atoms. The metal may be In, Sn, Al, Ga, Zn, Cd, Sb, Bi, Ge, Mn, Ti, Nb, V, Cr, Mo, Fe, Y, Mg, Co, as well as mixtures thereof. Further processing of the metal-organic precursor (e.g. by pyrolysis, hydrolysis, or alcoholysis) produces metal oxide nanocrystals of desired characteristics. An metal-organic precursor of indium tin oxide (ITO) may be synthesized by reacting indium metal and tin metal with an organic acid having an aliphatic chain longer than three carbon atoms (e.g. stearic acid) at a temperature above 200° C. Further processing of the resulting metal-organic precursor yields ITO nanocrystals of regular shape, uniform size, and average diameter ranging of between about 1-500 nm. | 10-15-2015 |

Metal species may be removed by contacting the material suspected of containing one or more metals with a thiolated fatty acid or ester thereof for a period of time and under conditions effective far the sequestration of the metal species by the thiolated fatty acid or ester thereof. The thiolated fatty acid or ester thereof comprising sequestered metal species may then be separated and recovered from the treated material. Moreover, following the treatment of aqueous liquids or mixtures, or suspensions or dispersions of solids in aqueous liquids, the resultant thiolated fatty acid or ester thereof comprising the sequestered metal species is insoluble in water and forms a separate layer from the aqueous liquid phase, which layer may be readily removed. | 11-26-2015 |

| 20080207934 | METHOD FOR PRODUCING METAL NANOPARTICLES AND METAL NANOPARTICLES PRODUCED THEREBY - The present invention relates to a method for producing metal nanoparticles and metal nanoparticles produced thereby, in particular, to a method for producing metal nanoparticles used for inkjet that comprises, preparing metal nanoparticles capped with a fatty acid; heating a mixture of the capped metal nanoparticles and a linear or branched first amine of C1-C7 so that a part of the fatty acid is substituted to the first amine; and heating after adding a linear or branched second amine of C | 08-28-2008 |
| 20110237813 | CO-PRECIPITATED SALTS OF FATTY ACIDS - A co-salt of a polyunsaturated fatty acid and a non-fatty acid is formed as a precipitate. The co-salt formed is free flowing and does not tend to agglomerate (cake) in storage. The resultant co-salt product will be easy to blend with other products to produce dietary supplements. These novel co-salt products may also tablet very well and may be added to current dietary supplement tablets. | 09-29-2011 |
| 20140179941 | Synthesis and Surface Functionalization of Particles - Provided are methods of controlling the shape and surface chemistry of nanoparticles, particularly ferrite nanoparticles. Methods for preparing non-spherical ferrite nanoparticles, including nanocubes, nanobars, nanoplates, and nanoflowers, are described. Also provided are methods of functionalizing the surface of metal and metal oxide particles. The surface functionalization methods do not require the use of chemical linkers and/or additional reagents, and permit the facile conjugation of a range of molecules, including bioactive agents, to the surface of particles. | 06-26-2014 |
| 20160090345 | FATTY ACID METAL SALT FOR FORMING ULTRAFINE METAL PARTICLES - A method of producing a powder of fatty acid metal salt for forming ultrafine metal particles includes washing the fatty acid metal salt so that the amount of unreacted substance or by-product is 4.0 mol % or less when the fatty acid metal salt is formed; preparing a pressed cake by pressing the fatty acid metal salt; and drying the pressed cake so that the water content is 200 ppm or less. The powder has a property for deodorizing mercaptan smelling components and/or a property for inactivating microproteins. | 03-31-2016 |

| 20150025258 | OIL SOLUBLE HYDROGEN SULFIDE SCAVENGER - The concentration of hydrogen sulfide in a hydrocarbon can be mitigated by intruding therein a zinc carboxylate oxo complex composition prepared by reacting particulate zinc oxide with a mixture of two or more carboxylic acids wherein the zinc carboxylate oxo complex composition is soluble in hydrocarbons. Useful acids useful include acetic acid, oleic acid, isobutyric acid, lineoleic acid, cekanoic acid, and neodecanoic acid. | 01-22-2015 |
