Alloy 800HT is a heat resistance material that is used in high temperature industrial applications such as steam/hydrocarbon reforming and ethylene plant tubes. Long time exposure under these service conditions cause the alloy to undergo microstructural changes. The alloy, in fa…

The structure of molten Au0.81Si0.19, Au0.72Ge0.28 and Ag0.74Ge0.26 alloys with a composition at or near to the eutectic was investigated by using neutron diffraction (ND). The results suggest that the Au-Au distance in the alloys is similar to that of liquid Au, there is a pref…

The application of gold and silver nanoparticles to areas such as medical research is based on unique optical properties exhibited by some metals. These properties are a direct consequence of localised excitations occurring at visible frequencies known as Surface Plasmon Resonan…
