The occurrence of various chemical forms of sulfur on the surface might provide for concentrating of microelements including the noble metals (NMs) in their surface-bound forms. The regular behavior of NMs (Au, Pt, Pd, and Ru) depending on the grain sizes (specific surfaces) of pyrite ...
A relation is presented from which the approximate constant Φ can be derived for arbitrary combinations of metals and Van der Waals crystals. Predictions for the heat of adsorption of the noble gases on arbitrary metallic substrates are presented in tabular form.A.R. Miedema and B.E. Nieuwe...
