Polydisperse Mixture of Gold Nano-Particles

Vicuña E., Viera O., Briano J.G., Castro M., Irizarry R., University of Puerto Rico, US

Colloids synthesized in water media, usually from direct reduction of a salt, always exhibit a size distribution, which may be characterized by TEM or SEM measurements. These are in essence polydisperse systems with a dispersion [...]

Raman Spectroscopy Study of SOx Species Adsorbed on Au Nanocluster Surfaces

Posada B., Mercado L., Hernandez S., Castro M., Castro W., Murillo L., Briano J., Irizarry R., Ishikawa Y., Castro M., Castro W., The University of Puerto Rico at Mayaguez, US

The reduction of Au3+ with SO3-2 is known to lead to the formation of gold nanoculsters and SO4-2 : n Au3+ + SO3-2 à + Aun + SO4-2 equation 1 This reaction is fundamental in [...]
