Microstructural characteristics in the BaSrNb0:3Ti0:7O3 thin film, grown on SrTiO3 substrate by computercontrolled laser molecular beam epitaxy, were characterized by means of transmission electron microscopy (TEM). It is found that the film is single-crystallized and epitaxially grown on the SrTiO3...

First-principles study of diffusion of Li, Na, K and Ag in ZnO

Journal of Physics-Condensed Matter

Based on ab initio total energy calculations, Li, Na and Ag interstitials are found to be stable with at least a 1.56 eV energy barrier to transform to a zinc substitutional site in ZnO, whereas K interstitial has a relatively small energ...

A Comparative Study of the Corrosion Behavior of Three Stainless Steels in an Eutectic (Li,Na,K)(2)CO(3) Melt with and without (Na,K)Cl Additives at 973K in Air

High Temperature Materials and Processes

The ternary carbonate eutectic mixture of Li(2)CO(3), K(2)CO(3) and Na(2)CO(3) as a heat transfer and storage medium has excellent thermophysical properties, but with high viscidity as compared with some other inorganic salts such as chlo...
