Synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (L-Arginine and L-Aspartic acid) are reported. The gold nanoparticles were reduced by sodium citrate and functionalized with L-Arginine at the pH of 7 and 11 and L-Aspartic acid at the pH of 7. Transmission electron microscopy, UV-Vis spectroscopy, dynamic light scattering, zeta p...
This paper is a continuation of the project we presented at the 2010 Santa Fe Symposium® in which we defined a characterization system and analysis of data on 18K gold alloys. The research carried out since then has enabled us to connect the physical-mechanical characteristics of each alloy with its chemical composition, thereby identifying the best solution possible to produce a specific item....

Ultra-thin gold nanowires (GNWs), with uniform surface crystallinity, appear much more active than gold nanoclusters in benzylic compound oxidation. Ethylbenzene oxidation was used as a model reaction and a radical chain reaction mechanism was revealed by the DFT method.
In the presence of large excesses of borohydride salts, gold monolayer protected-clusters can be grown to larger sizes simply by controlling the amount of reducing agent added to smaller clusters. In addition, gold monolayer clusters can be used as catalysts for reduction reactions by sodium borohydride; results suggest such catalysts have sterically constrained active sites.
