A method, based on Monte Carlo constrained optimization, has been devised for designing superalloys. The Larson-Miller parameter at 100 MPa is maximized subject to Md (total) 4.32, Mo/(Mo + W) < 0.27. The maximum density of the alloy can be specified

The oxidation of FeF 2 -4H 2 O surface layers in an atmosphere saturated with water vapour was studied by means of Mossbauer spectroscopy as well as gravimetry. The major rust product is identified as β-FeOOH, and the reaction is shown to proceed as

Electron energy loss spectroscopy (EELS) has been used to study the room temperature chemisorption of oxygen on tin. EELS spectra are presented that show a continuous shift in surface plasmon energy loss from 10 to 6.5 eV during oxidation. The energy
