“…HAuCl 4 was prepared by dissolving a gold wire (99.9%) in aqua regia following the protocol described elsewhere. 69 An aqueous solution containing 2.54 ϫ 10 Ϫ2 M HAuCl 4 was prepared. In a typical nanoparticle synthesis where the TMA/Au molar ratio of 2.5 was used, 19.7 mL (0.50 mmol) of the HAuCl 4 solution was added to an Erlenmeyer and stirred with 100 mL of methanol.…”

Synthesis and Characterization of Gold@Gold(I)−Thiomalate Core@Shell Nanoparticles

et al. 2010

In this paper, the synthesis of gold at gold(I)-thiolate core at shell nanoparticles is described for the first time. The chemical nature and structure of these nanoparticles were characterized by a multi-technique approach. The prepared particles consist of gold metallic cores, about 1 nm in size, surrounded by stable gold(I)-thiomalate shells (Au at Au(I)-TM). These nanoparticles could be useful in medicine due to the interesting properties that gold(I)-thiomalate has against rheumatoid arthritis. Furthermore, the described results give new insights in the synthesis and characterization of metallic and core at shell nanoparticles.

Au–Pd Alloy Gradients Prepared by Laterally Controlled Template Synthesis

et al. 2006

View full text Add to dashboard Cite

Lateral control of template synthesis in nanoporous alumina membranes (NAMs) was previously shown by us to enable preparation of graded composite materials. Formation of thickness gradients of Cu was demonstrated using electrodeposition (or electrodissolution) of Cu in the NAM template under a lateral voltage drop applied to the working electrode. This approach is extended here to the formation of compositional gradients. The latter are achieved by electrochemical co‐deposition of two metals (Au and Pd) in the membrane pores from a mixed metal‐ion solution under a lateral potential drop, to form an alloy that shows a continuous lateral change of the Au/Pd ratio. Environmental scanning electron microscopy images of cross sections along the line of the applied voltage gradient show that the deposit height changes gradually, while local elemental analysis by energy dispersive spectrometry and X‐ray diffraction measurements confirm a continuous change of the alloy composition along the membrane matrix.
