Magnetic Moment Distribution in Dilute Alloys of Nickel in ...

The magnetic cross sections, measured with scattering vectors ranging from 0.17 to 1.1 Å-1, are all strongly peaked towards the forward direction. The range of polarization of the palladium matrix around a nickel atom deduced from the measurements is independent of nickel concentration up to 4.7 at.%

Nickel in Drinking-water - whot

Nickel is used mainly in the production of stainless steels, non-ferrous alloys, and super alloys. Other uses of nickel and nickel salts are in electroplating, as catalysts, in nickel–cadmium batteries, in coins, in welding products, and in certain pigments and electronic products (IARC, 1990). It is estimated that 8% of nickel is used for
