Gold composites

FIGURE 4-29 Cottrell plot of the chronoamperometric response for 1 x 1(T3M Ru(NH3)63 + at a Kel-F/gold composite electrode. Points are experimental data, the solid line is the least-squares fit to theory. Dashed lines are theoretical Cottrell plots for a macroelectrode with active area equal to the active area of the composite (curve a) and to the geometric area of the composite (curve b).

To study the biodistribution of gold composite nanodevices we have developed methods that permit post-synthetic activation of gold in the nanocomposites into Au by a brief neutron bombardment without damaging the host macromolecules. In principle, this permits us to construct and characterize Au composite nanoparticles, and then activate the gold to the specific activity of Au desired for the experiment, while using the cold version as a control. Studies similar to those above with...

The synthesized Au-Ag alloys were fully characterized before and after acetylation. It was demonstrated that both Au atom/Ag atom/dendrimer molar ratio and the acetylation modification influence the size of binary nanoparticles. With constant total metal atom/dendrimer molar ratio, the size of alloy nanoparticles decreases with gold composition. For particles with similar metal composition, the size of the particles becomes slightly larger after acetylation [47]. 

Transmission electron microscopy was also performed on PMMA/gold composite samples using a Phillips EM 300 instrument. The samples were prepared by microtoming to a thickness of 80 X. 

A new method for the chemical deposition of carbon/gold composite nanotubes in alumina templates has been proposed recently (79). It is based on the impregnation of the template pores with diluted hydrogen tetrachloroaurate (HAuCy/acetone solutions and subsequent thermolysis. Gold(lll) is reduced, whereas the solvent acetone is oxidized. The results are nanotubes whose walls consist of gold nanocrystals supported by amorphous carbon. The authors report that when the template pores have a diameter smaller than 180 nm, single crystal gold nanowires are obtained.

The ionic polymer-metal composite (IPMC, which is also known as ICPF in the robotics field) [10, 11] is one of the electroactive polymers that have shown potential for practical applications. The IPMC is an chemically plated electroactive polymer (EAP) material that bends when subjected to a voltage across its thickness (Figure 8.1). A Nafion-gold composite type IPMC [12], which contained the sodium ion, has a relatively good...

The water gas shift reaction (CO+HgO Hg+COg) is one of the critical processes for providing hydrogen for industrial applications. Ceria-noble metal composite catalysts have proved to be a competitive alternative for traditional catalysts in low-temperature water gas shift (LTS) reactions. Flytzani-Stephanopoulos and co-workers made a series of studies on nanostructured ceria-gold composite catalysts for The composite was made of ceria or La-doped ceria...
