Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This is an enabling product and can be used as a precursor for thin layer deposition, which is an efficient technique for finding high-performance materials. Click here for more information.

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.Reports show that the rate of dissolution of Au is very fast in SnPb solder.

Application

Gold based neutron flux monitors may use gold foils. Au foils may be used to form a AuSn/Au joint system for opto-electronic chips. 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.
