* In the Au/ADA spectra, no peaks were seen in the λ500nm range, instead, a slight peak was seen around λ250-325. What this peak represents, we are not sure. | * In the Au/ADA spectra, no peaks were seen in the λ500nm range, instead, a slight peak was seen around λ250-325.

* For the newly made Au/ADA solutions at mole ratios 10-45, some of the samples produces a slight purple tinge prior to its placement in the oven. As a result, a UV-Vis spectrum of these samples ( mole ratios 10, 15, 40, 45) was taken. For full details on the makings of these samples, please see Michaels Notebook | * For the newly made Au/ADA solutions at mole ratios 10-45, some of the samples produces a slight purple tinge prior to its placement in the oven.

Nagle/Notebook/Chem 571/2012/11/29| Michaels Notebook]]. His results showed that in the 25-33 mole ratio range, purple solutions were present without fibers. Further zeroing in on this range needs to be done in the fugure in order to more specifically determine the mole ratio of Au to ADA that leads to the formation of nanoparticles in solution. | ||
