Beschreibung

Allgemeine Beschreibung

Gold is one of the most popular materials to be used for neutron flux monitoring mainly because it possesses a large thermal cross section for neutron capture (¹⁹⁷Au(η, η) ¹⁹⁸Au. Gold has the half-life of 2.7 days.[1]Reports show that the rate of dissolution of Au is very fast in SnPb solder.[2]

Anwendung

Gold based neutron flux monitors may use gold foils.[1] Au foils may be used to form a AuSn/Au joint system for opto-electronic chips.[2] Modified gold foil electrode may be used to study heterogeneous electron transfer properties of biological electron transfer proteins.3 Electrodeposited polycrystalline palladium-nickel alloy on gold foils may be investigated for the enhanced catalytic behavior of the alloy.[3]
