Publication number: 20120227545Abstract: This invention relates to a process for the recovery of precious metal/s from a precious metal-containing material in an aqueous leach slurry or solution. The process includes the step of contacting the precious metal/s in the leach slurry or solution with a ligand selected from dithiooxamide (rubeanic acid), or a substituted dithiooxamide. The leaching of PGMs, gold and silver from their ores using the ligand of the present invention may take place under aqueous alkaline conditions, avoiding both corrosive acidic conditions and the use of cyanide.Type: ApplicationFiled: July 21, 2010Publication date: September 13, 2012Applicant: ANGLO OPERATIONS LIMITEDInventors: Diandree Padayachee, Makhosazane Chucky Kunene, Marga Retha Burger, Noko Simon Phala

Patent number: 8206692Abstract: The present invention relates to a method for screening compounds having the ability to prevent, treat or reduce malodor development on body surfaces. In particular, the method allows to efficiently screen for compound having the ability of preventing sweat malodor development caused by volatile sulfur compounds (VSCs). The present invention is based on the finding of the direct precursor of naturally VSCs, which is present in human sweat and which will be metabolized by Staphylococci to VSCs.Type: GrantFiled: July 18, 2007Date of Patent: June 26, 2012Assignee: Firmenich SAInventors: Christian Starkenmann, Anthony Clark, Myriam Troccaz, Yvan Niclass

Publication number: 20120107835Abstract: A method for detecting ?-amyloid using an amino acid dimer instead of a secondary antibody binding to the ?-amyloid primary antibody in an immunoassay based on an antigen-antibody reaction, and a kit for detecting ?-amyloid including the dimer. The method is advantageous in that the dimer has good properties in stability, availability, and storage compared to antibodies and that it can detect various ?-amyloids by using one kind of antibody, and thus may be effectively used in early diagnosis and research of Alzheimer's disease.Type: ApplicationFiled: October 7, 2011Publication date: May 3, 2012Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventor: Hyo Bong Hong
