Influence of base electrolytes on the electrodeposition of iron onto a silicon surface
Article Abstract:
Comparative electrodeposition of iron onto the surface of silicon is investigated at large overpotential in the presence of some base electrolytes and the nanostructure of the iron electrodeposits was analyzed with scanning electron microscopies (SEM) and field emission-SEM (FE-SEM) measurements. The results have highlighted the effects of ion specificity on the rate of hydrogen evolution and of selective ion adsorption on the morphology of the iron electrodeposits.

Au nanoparticles prepared by physical method on Si and sapphire substrates for biosensor applications
Article Abstract:
The preparation of gold nanoparticles directly deposited onto the surface of silicon and sapphire substrates by a physical methodology, consisting in the thermal evaporation of a thin Au film and its successive annealing is reported. The method guarantees the preparation of monodispersed single-crystal Au nanoparticles with a strong surface plasmon resonance peak centered at about 540 nm.

Electron transport dynamics in a room temperature Au nanoparticle molten salt
Article Abstract:
A room-temperature [Au.sub.38] nanoparticle polyether melt is prepared by exchanging poly(ethylene glycol) (PEG) thiolate ligands, HS-C6-[PEG.sub.163], into the organic protecting monolayer of A[u.sub.38][Ph[C.sub.2].sub.24] nanoparticles. The electron hopping dynamics between Au nanoparticles and the mass transport properties of electrolyte ions are studied at room temperature.
