Long-chain alkanethiols I R(CH,),SH] and substituted phenylthioureas (RPhNHCSNH,) adsorb from solutions on the surface of gold. Analysis by XPS indicates that the binding energies of the S 2p and Au 4d, peaks in alkanethiol monolayers are 162.3 and 335.4 eV, which are 1.4 and 0.4 eV higher than thos

Galvanic gold is an important protective Γnal layer in most low-level electrical contacts for high-reliability applications. Despite the chemical inertia of gold, it is widely admitted that adding an organic layer (polyphenyl esters, perΓuorinated polyethers) to such surfaces minimizes friction and
**Surface diffusion coefficients (****__D__****)** have been measured for gold nanorods suspended in water on planar gold substrates. The Figure shows the composite image of sequential optical micrographs at 15 s intervals. The variation of __D__ is more dependent on rod length than predicted by the
Figure 4 shows a nanotube array grown under similar conditions as for cylinders, except that the nucleation was with 5 nm diamond particles along the pore walls of alumina membranes. The tubes are well ordered but somewhat tilted due to their relatively low mechanical strength compared with cylinder
