A coordination-assisted synthetic approach is reported here for the synthesis of highly active and stable gold nanoparticle catalysts in ordered mesoporous carbon materials using triblock copolymer F127 as a structure-directing agent, thiol-containing silane as a coordination agent, HAuCl4 as a gold source, and phenolic resin as a carbon source. Upon carbonization, the gold precursor becomes re...

This article describes the generation of the Human Combinatorial Antibody Library HuCAL GOLD. HuCAL GOLD is a synthetic human Fab library based on the HuCAL concept with all six complementarity-determining regions (CDRs) diversified according to the sequence and length variability of naturally rearranged human antibodies. The human antibody repertoire was analyzed in-depth, and individual CDR l...

Nanogap devices have applications in single molecule sensing and single molecule transistors. Nanogap devices comprised of a gold nanowire with a nanoscale gap containing C60 were fabricated using electromigration on a silicon substrate. Raman spectra were obtained for various features of this device in order to detect the presence of C6o and study its electronic properties. The 532 nm laser so...

This article describes the characteristics of gold–sulfide–quartz and gold–sulfide (gold–arsenic) ore occurrences in Manitanyrd region Polar Urals. Ore are confined to NE-trending shear zones have common features a geological structure. The host rocks metamorphosed volcanic volcanic–sedimentary rocks. We analyzed mineral chemical composition mineralization all studied occurrences, showing that ...

Abstract Mantle plume rich in gold is considered to be important for the formation of giant epigenetic deposits. The Youjiang basin, SW China, world’s second largest Carlin-type province, but ultimate source its remains enigmatic. In this study, we report that Middle–Late Permian basaltic rocks basin are native grains. These grains scattered interstices pyrite and marcasite amorphous silica cav...

since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. after gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, one of these methods is activated carbon.the loading of gold from industrial thiosulfate solut...
