Wormlike micelles (WLMs) are nanoscale, self-assembled components of many products from shampoos to fracking fluids due to their viscoelasticity. Their rheological behavior is largely governed by the contour length of the micelles and the concomitant

Wormlike or threadlike structures with local cylindrical geometry are abundantly found in nature and technical products. A thorough structural characterization in the bulk for a whole ensemble, however, is difficult. The inherent semiordered nature o

The voltammetric electrooxidation rates of formic acid, formaldehyde, and methanol in acidic electrolyte on carbon-supported platinum nanoparticle films with varying particle diameters (d) in the range of ca. 2−9 nm are examined with the objective

The electrochemical reduction of nitrous oxide on iridium single-crystal electrodes constitutes a paradigmatic example of sensitivity to the surface structure. Ir(111) and Ir(110) electrodes catalyze the process, while Ir(100) is almost totally inact

A comparison is made between electrochemical infrared reflection−absorption spectra for carbon monoxide adlayers formed on carbon-supported platinum nanoparticle films by direct chemisorption from solution CO and via methanol dissociation. In addit

Some recent applications of surface-enhanced Raman spectroscopy (SERS) to the characterization of adsorbates at metal surfaces in electrochemical and ambient gaseous systems taken from studies in our laboratory are described with the objective of ill

An analysis is outlined that utilizes electrode potential-dependent measurements of the intramolecular vibrational frequency (νc) for chemisorbates, specifically carbon monoxide and nitric oxide, at ordered Pt-group metal−solution interfaces (i.e.

The possibility that adsorbed carbon monoxide may act as a reaction intermediate rather than merely a catalytic poison for formic acid electrooxidation on Pt-group metals in aqueous perchloric acid is explored by monitoring the time-dependent effects

Model electromagnetic (EM) calculations are presented of the surface-enhanced Raman scattering (SERS) intensities expected for gold and silver particles coated with conducting as well as insulating dielectric films, with the objective of assessing th

Infrared spectra are reported for saturated CO adlayers on highly ordered Pt(111) and related stepped surfaces in aqueous 0.1 M HClO4 with the objective of ascertaining the importance of long-range substrate structure to the surface-binding configura
