Single-energy wash-in photoacoustic blood flow measurements using shape transitions of gold nanorods
SPIE Proceedings, 2006A time-intensity based method for photoacoustic blood flow measurements was proposed in last year's meeting. The method made use of the strong photoacoustic response of gold nanospheres and the "wash-out" characteristics of the nanospheres were analyzed. In this paper, we develop a new quantitative technique for measuring blood flows based on the "wash-

Effect on the Chromatographic Behavior of Gold of the Process Used to Acid-Wash Polyurethane Foam
Chromatographia, 2007The effect on polyurethane foam (PUF) of washing with different concentrations of HCl (1, 3, 6, or 11.8 M) has been studied. After washing, PUF was characterized by use of different techniques. The adsorption properties of PUF and its chromatographic behavior in the separation and preconcentration of gold from thiocyanate solution were investigated by ...

Effects of Quebracho Tannin on Recovery of Colloidal Gold from Bioleached Wash Liquor
2015Gold occurs in some concessions as submicron particles in pyrite and arsenopyrite, which is processed in a flotation concentration to obtain gold enriched sulphide concentrate. The concentrate is then treated in a biological oxidation step to oxidize the sulphides, liberate the occluded gold and make them amenable for cyanidation. The oxidized sulphide
