Enormous hyper-Rayleigh scattering from nanocrystalline gold particle suspensions
Article Abstract:
A study was conducted to analyze aqueous colloidal suspensions of gold particles using hyper-Rayleigh scattering. The effects of NaCl addition on Rayleigh and hyper-Rayleigh scattering signal intensities were also examined. Results indicated that the nanoscale particles supported efficient scatterers. Findings also confirmed the effectiveness of using hyper-Rayleigh scattering in characterizing the symmetry-reducing perturbations of nanoscale interfaces.

EQCM investigations of dye-functionalized nanocrystalline titanium dioxide electrode/solution interfaces: does luminescence report directly on interfacial electron transfer kinetics?
Article Abstract:
It was shown that reversible, potential-induced dye desorption occurs in both aqueous and nonaqueous environments at potentials close to the conduction band edge. Electrochemical quartz crystal microbalance experiments were carried out on dye-functionalized nanocrystalline titanium dioxide electrode/solution interfaces. Findings also showed decreases in the efficiencies of charge injection and increases in dye luminescence yield during potential changes.

Interrogation of nanoscale silicon dioxide/water interfaces via hyper-Rayleigh scattering
Article Abstract:
A study was conducted to analyze the interrogation of nanoscale silicon dioxide/water interfaces using hyper-Rayleigh scattering experiments. The samples were made by diluting sols with water to a final 0.27 M concentration of SiO2. A mode-locked Ti:sapphire laser was utilized to produce the incident radiation. Experimental results indicated the effectiveness of the scattering method in analyzing particles under native solution-phase conditions.
