Underpotential deposition of lithium on aluminum in ultrahigh-vacuum environments

Article Abstract:

Research was conducted to examine the electrochemical characteristics of clean aluminum in LiClO4(PEO) solutions in ultrahigh vacuum using as electrodes both foils and thin films vapor deposited on boron-doped diamond layers supported on Si substrates. The study was motivated by a theory predicting that Li and Na underpotential deposition (UPD) shifts on low-inded Al single-crystal surfaces. Results revealed a clearly defined peak in the scan in the positive direction centered at ca. 0.90 V which is attribute to the stripping of UPD Li on Al.

Structure, energetics, and dynamics of water adsorbed on the muscovite (001) surface: A molecular dynamics simulation

Article Abstract:

Molecular dynamics simulations at constant temperature and volume were performed for a series of model systems consisting of a two-layer muscovite slab, and 0 to 319 adsorbed H2O molecules, probing the atomistic structure and dynamics of surface aqueous films up to 3 nm in thickness. The simulations predict that a full molecular monolayer surface water coverage represents a relatively stable surface structure in terms of the lowest diffusional mobility of H2O molecules along the surface.

Surface dynamics of coadsorbed CO and D(sub 2)O on Pt(100) in ultrahigh vacuum as studied by time-resolved infrared reflection absorption spectroscopy

Article Abstract:

The vibrational features of CO adsorbed on Pt(100) surfaces at saturation coverages exposed subsequently to various amounts of water at 105 K in ultrahigh vacuum were monitored by time-resolved infrared reflection absorption spectroscopy. The findings indicated that under the conditions of the experiments, the interfacial dynamics are relatively slow, involving a gradual rearrangement of adsorbed Co and D(sub 2)O on the surface to yield surface solvated CO.
