The effect of lattice periodicity on the electronic configuration near a metal surface
… The solution is sufficiently general to include surface states. The single electron potentials are reconsidered and some new features are discussed. These include the elimination of the singular zero-order Fourier terms of the ion-electron and Hartree potentials which leads to the surface dipole …

A multiscale study of atomic interactions in the electrochemical double layer applied to electrocatalysis
… of kinetics and reactant coverages on the surface can help to propose new mechanisms when energy prediction and experimental uncertainties still prevail. ORR kinetic limitation is often rationalized in terms of surface poisoning by parallel reactions, namely water oxidation, and/or as a …

Adsorption of phloretin to lipid layers
… which do not contain proteins. Since the dipole potential reducing effect of phloretin on mono- and bilayers has been found, it became clear that its primary effect must be a biophysical one: phloretin adsorbs to lipid layers and changes biophysical parameters of these layers. The aim of …

Study of semiconductor and metal surfaces using a novel scanning Kelvin probe.
… vibrating reference electrode (the tip) and the surface under investigation. It utilises a non-contact, non-destructive measurement mode allowing work function measurements at temperatures in the range from (300 - 1100) K. The work function is a multi-parameter variable highly sensitive to …

X-ray timing of the accreting millisecond pulsar SAX J1808.4-3658
… dims, the X-ray "hot spot" on the pulsar surface drifts longitudinally and a second hot spot may appear. The overall pulse shape variability limits the ability to measure spin frequency evolution within a given X-ray outburst (and calls previous zi measurements of this source into …

Multi-Photon Spectroscopic Studies of Molecule/Metal Interfaces and Graphene
… focus on the role of adsorbates in shifting surface polarization and effecting surface electron confinement. As the coverage of each molecule increases, their photoemission-measured work functions exhibit nearly identical behavior up to 0.4-0.5 ML, at which point their behavior diverges; this …
