Determination of the Surface Charge Density of Colloidal Gold Nanoparticles Using Second Harmonic Generation
TL;DR: In this article, the surface charge density of 50 nm colloidal gold nanoparticles in water was investigated using the χ(3) technique and the experimental results were fit to the Gouy-Chapman model and numerical solutions to the spherical Poisson-Boltzmann equation that account for the nanoparticle surface curvature, the different salt valences, and ion adsorption to the Stern layer interface.

Mechanism of revert spacing in a PbCrO4 Liesegang system.
TL;DR: It is shown that this correlation in opposite directions decisively reveals the role of adsorption in the mechanism and increases as the band number increases in revert spacing systems, while it decreases as n increases in direct spacing systems.

Enhanced Photothermal Effects and Excited-State Dynamics of Plasmonic Size-Controlled Gold–Silver–Gold Core–Shell–Shell Nanoparticles
TL;DR: In this article, the synthesis, characterization, and excited-state dynamics of colloidal gold-silver-gold core-shell-shell nanoparticles are reported, and the ratio of the gold shell thickness to the overall particle size shows a linear dependence with the position of the plasmon extinction peak wavelength.

TL;DR: In this article, the second harmonic generation was used to investigate the adsorption properties of malachite green, brilliant green, and methyl green to the surface of 80 nm colloidal gold nanoparticles capped with mercaptosuccinic acid in water.
