Metallic superlattices with planar, unalloyed (unmixed) interfacial structures are difficult to fabricate by all conventional vapor deposition methods. Molecular dynamics simulations have been used to explore the ways in which inert gas ions can be used to control the atomic assembly of a model Cu/Co metallic super lattice system. High energy, high atomic weight ions are shown to smooth rough i...

We re-examine the electronic response of the Chevrel phase Mo6S8 upon Mg intercalation. The ground state Mo6S8 is metallic and exhibits strongly localized electronic screening of Mg(2+) ions. This localized screening cloud effectively shields the 2+ charge carried by Mg ions on the length scale of one unit cell and facilitates Mg ion diffusion.

The presence of nanoparticles in many industrial applications and daily products is making it nowadays crucial to assess their impact when exposed to the environment. Metallic nickel nanoparticles (Ni NPs) are of high industrial interest due to their ability to catalyze the reversible hydration of CO2 to carbonic acid at ambient conditions. We characterized metallic Ni NPs by XRD, HRTEM and EDS...

Metallic materials in practical use are normally exposed to corrosion in the atmospheric and aqueous environments. Metallic corrosion is one of the problems we have often encountered in our industrialized society; hence it has been studied comprehensively since the industrial revolution in the late eighteenth century. Modern corrosion science was set off in the early twentieth century with the ...

In this paper, we present the self assembly procedure as well as experimental results of a novel method for constructing well defined arrangements of self assembly metallic nano particles into sophisticated nano structures. The self assembly concept is based on focused ion beam (FIB) technology, where metallic nano particles are self assembled due to implantation of positive gallium ions into t...
