9. It was observed that hydrophobic substrates gave better monolayer transfer ratios, and therefore, quartz substrates were rendered hydrophobic by transfer of 1 ML of lead arachidate. The gold-coated quartz crystals for QCM were hydrophobic and used without further treatment.

13. 3]/16 ≈ 11225. From a similar calculation, the number of gold atoms in a 130 Å size cluster is ca. 71897. Therefore, the gold:silver molar ratio in a film containing equal numbers of silver and gold clusters is 71897/11225 ≈ 6.5. Since the Au:Ag molar ratio from XRF measurements for the 1:1 film is 4.5, this implies a Au:Ag cluster density ratio of 4.5/6.5 ≈ 0.7.
