Equiatomic (Au,Cu) solid solution orders below 658 K to form a tetragonal AuCu (I) phase with significant changes in physical properties and the crystal structure. The effect of ordering on the dielectric function of the material is controversial however, with inconsistent results reported in the literature. Since the nature of any localized surface plasmon resonance (LSPR) in the nanostructures is very sensitive to the dielectric function, this uncertainty hinders the use of AuCu in plasmonic devices or structures. Therefore, we re-examine the question using a combination of measurements and computations. We find that no significant change in the dielectric function occurs when this material becomes ordered, at least over the range of photon energies relevant to LSPRs. The likely properties of LSPRs in plasmonic devices made of AuCu are analyzed. Use of the alloy offers some advantages over pure Cu, however pure Au would still be the superior option in most situations.

Time-dependent density functional theory (TDDFT) was used to calculate the optical absorption spectra of gold clusters of 20-171 atoms. The spectra for the smallest clusters agree with previous results, and the spectra for the largest clusters show features consistent with classical Mie theory. The systematic exploration of particles of sizes within these two extremes has allowed the trends linking optical absorption spectra and particle size and symmetry to be identified. A transition from molecular-like spectra to a more classical response is observed. © 2014 American Chemical Society.

the sp3 (diamond like bonding) fraction and surface properties are the important determining factors among all structural and compositional characteristics which control the biocompatibility of diamond-like carbon (DLC) coating. Previous reports in this area have not adequately correlated these factors with coating optimization for specific biomedical applications. The present work is aimed at studying the effect of the structural and compositional properties on the biocompatibity of both hydrogenated and unhydrogenated tetrahedral DLC films produced by commercial deposition methods. Electron energy loss spectroscopy (EELS) and X-Ray photoelectron spectroscopy (XPS) were used for structural and compositional characterization. The human bone derived cells (HBDC) 3 day cell-culture showed good attachment to the DLC surfaces but no significant difference in morphology on different types of DLC. Blood protein adsorption study showed an increased albumin to fibrinogen ratio as the sp 3 fraction increases. © 2006 IEEE.

Electron energy-loss spectroscopy (EELS) is widely used to study the composition and electronic structure of materials at the nanometre scale. The low-loss region of the EEL spectrum (< ~50 eV) is of particular interest for the study of optical properties. Examples of the applications of EELS to measure the optical properties, and, in particular, of individual nanoparticles will be presented. Comparison to calculations of optical properties and EEL spectra using density functional theory will be given.

Electron energy loss spectroscopy and density functional theory have been used to show that there is a covalent component to the bonding in NiAl, CoAl and FeAl, between the transition metal atom and Al. There is no charge transfer and no ionic component to the bonding in NiAl and probably not in CoAl and FeAl. The bonding in non-stoichiometric NiAl is studied. Preliminary results are given for a £3 boundary in NiAl. © 1999 Materials Research Society.
