Forced Electrocodeposition of Silica Particles into Nickel Matrix by Horizontal Impinging Jet Cell

Hubert Girault, Véronique Amstutz, Desire Martial Koutouan Abro

The improvement of silica particle codeposition into a nickel electrodeposited composite coating (ECC) by a double face horizontal impinging jet cell (IJC) has been studied. The microstructure of coatings was examined by means of scanning electron microsco ...

Where Does Energy Go in Electron Energy Loss Spectroscopy of Nanostructures?

Jürgen Brugger, Olivier Martin, Duncan Thomas Lindsay Alexander, Jérémy Butet, Valentin Flauraud, Gabriel David Bernasconi

Electron energy loss spectroscopy is a method of choice for the characterization of both the spatial and spectral properties of localized surface plasmon resonances. The energy lost by the impinging electrons is commonly explained by the Lorentz force acti ...

Indium selenide: an insight into electronic band structure and surface excitations

Davide Campi

We have investigated the electronic response of single crystals of indium selenide by means of angle-resolved photoemission spectroscopy, electron energy loss spectroscopy and density functional theory. The loss spectrum of indium selenide shows the direct ...

Structural, tribo-mechanical, and thermal properties of NbAlN coatings with various Al contents deposited by DC reactive magnetron sputtering

Silviu Cosmin Sandu

DC reactive magnetron sputtered Nb2AlyNx coatings with various Al contents (y/(y + z)) ranging from 0 to 0.75 were deposited using different ratios of the currents applied to the Al and Nb targets in order to systematically control their chemical compositi ...

Negative plasmon dispersion in 2H-NbS2 beyond the charge-density-wave interpretation

Helmuth Berger

We examine the experimental and theoretical electron-energy loss spectra in 2H-Cu0.2NbS2 and find that the 1 eV plasmon in this material does not exhibit the regular positive quadratic plasmon dispersion that would be expected for a normal broad-parabolic- ...

p,t-[Ru(CO)(PR3)(tren)](2+) [R=Ph or p-tol; tren=tris(2-aminoethyl)amine], Ru(II) complexes bearing a simple tripodal tetradentate amine: synthesis, characterization, and antimicrobial activity

Paul Joseph Dyson, Rosario Scopelliti, Francisco Dinis Fagundes

Complexes with general formula p,t-[Ru(CO)(PR3)(tren)]X-2 [R=Ph (1) or p-tol (2); tren=tris(2-aminoethyl)amine; X=Cl- or PF6-] were prepared from [RuCl2(CO)(dmf)(PR3)] by direct reaction with tren. The complexes were fully characterized by NMR (H-1, P-31{H ...

Tetracarboxylatoplatinum(IV) complexes featuring monodentate leaving groups - A rational approach toward exploiting the platinum(IV) prodrug strategy

Hristo Plamenov Varbanov

A series of novel symmetrically and unsymmetrically coordinated platinum(IV) complexes with monodentate carboxylato ligands was synthesized. The compounds exhibit a general coordination sphere of [Pt(en)(OCOR)(2)(OCOR')(OCOR '')1, where the carboxylato lig ...
