Secondly, devaluation would not in itself re-adjust the maldistribution of gold. Creditor countries would continue to attract the world s gold and if they persisted in high tariff policies, it would still be difficult for debtor countries to make payments, or for the volume of world trade to ...
The Fermi Surfaces of Copper, Silver and Gold I. The de Haas-van Alphen Effect Following the discovery of the effect in copper, silver and gold by the impulsive high-field method, a study of the variation of the oscillatory frequency (which is proportional to the extremal area of cross-sec...
The catalytic activity of copper, silver and gold foils, of a silver-lead (0.69 atom %) alloy foil and of several granular silver catalysts has been studied in the hydrogen-deuterium-exchange reaction. Observed activation energies and temperature ranges of activity of the catalysts have been measu...
Silver-gold (Ag-Au) alloys (2.2 at% to 60 at% Au) were found susceptible to stress corrosion cracking (SCC) in 1 M potassium chloride (KCl), 1 M potassium bromide (KBr), and 1 M potassium iodide (KI) aqueous solutions. Cracks were mainly intergranular, and there was no evidence of...
Silver films(Ag) and silver-gold films(Ag-Au) with thickness ~15nm are coated on Bk7 glasses through thermal evaporation.After doping gold of 5.2%,the grain size of the Ag film reduces from 13.6nm to 9.1nm,also the surface roughness decreases from 1.45 nm to 0.94 nm.A UV lamp is used...
Background The type of antibody-conjugated polystyrene (PS) latex beads for use as light scatter shift agents for targeted lymphocyte populations in whole blood has been expanded to include gold and silver nanoparticle-aminodextran-PS latex bead conjugates with antibodies. The linkers between antibody...

If Ag2S nanocrystals were transported to the bulk, a peak would appear in the EDS spectrum around 3 keV. Absence of this signal in the un-spiked supernatant indicates nano-Ag2S is not transported by the soft corona. Sulphur sources and Ag/S ratio influence nano-Ag2S formation Sulphur-...
