An in-situ FTIR spectroscopic study of the electrochemical oxidation of ethanol at a Pb-modified polycrystalline Pt electrode immersed in aqueous KOH.

11-09-2013 | Paul Christensen; Steven Jones; Andrew Hamnett, Physical Chemistry Chemical Physics, 2013

A study of the mechanism of ethanol oxidation in alkaline solution on a platinum electrode modified with a upd layer of lead has been carried out using in situ FTIR spectroscopy. This study provides support for the suggestion that the adsorption mechanism of ethanol is substantially modified in ...

Phase Transitions of Polystyrene-b-poly(dimethylsiloxane) in Solvents of Varying Selectivity

06-09-2013 | Ting-Ya Lo; Chia-Cheng Chao; Rong-Ming Ho; Prokopios Georgopanos; Apostolos Avgeropoulos; Edwin L. Thomas, Macromolecules, 2013

A simple method to create a variety of nanostructures via the self-assembly of a single composition silicon-containing block copolymer (BCP) is developed. By using selective solvents for the self-assembly of polystyrene-block-poly(dimethylsiloxane) (PS–PDMS), the phase behavior of intrinsic BCP ...

Oscillations in the Permanganate Oxidation of Glycine in a Stirred Flow Reactor

05-09-2013 | Eszter Poros; Krisztina Kurin-Csörgei; István Szalai; Miklós Orbán, Journal of Physical Chemistry A, 2013

Oscillatory behavior is reported in the permanganate oxidation of glycine in the presence of Na2HPO4 in a stirred flow reactor. In near-neutral solutions, long-period sustained oscillations were recorded in the potential of a Pt electrode and in the light absorbance measured at λ = 418 and 545 ...

Unsymmetrically Substituted 1,1′-Biferrocenylenes Maintain Class III Mixed-Valence Character

05-09-2013 | Rochus Breuer; Michael Schmittel, Organometallics, 2013

UV–vis–near-IR electronic absorption spectra of unsymmetrically substituted derivatives of 1,1′-biferrocenylene (bis(fulvalene)diiron = BFD) have been systematically evaluated upon oxidation using spectroelectrochemical techniques. Upon reversible electrochemical oxidation to the BFD+ monocation ...

Iodine-sensitized oxidation of ferrous ions under UV and visible light: The influencing factors and reaction mechanism

04-09-2013 | Lianghui Wan; Yiming Xu, Photochemical & Photobiological Sciences, 2013

Sensitized oxidation of Fe2+ ions by I2 or I3– in acidic aqueous solution has been examined. The reactions could occur either under UV or visible light, with the stoichiometric formation of Fe3+ and I–. However, the I3–-sensitized reaction was fast and complete only in the presence of Fe2+. ...

Antibiotic Detection in Urine Using Electrochemical Sensors Based on Vertically Aligned Carbon Nanotubes

27-08-2013 | Fernando C. Moraes, Tiago A. Silva, Ivana Cesarino, Marcos R. V. Lanza, Sergio A. S. Machado, Electroanalysis, 2013

Abstract A sensitive way to determine levofloxacin using a sensor based on vertical aligned carbon nanotubes is described. The morphology and the electrochemical performance of the electrodes were characterised by atomic force microscopy, cyclic voltammetry and square wave voltammetry. A ...

Protic Ionic Liquids as p-Dopant for Organic Hole Transporting Materials and Their Application in High Efficiency Hybrid Solar Cells

27-08-2013 | Antonio Abate; Derek J. Hollman; Joël Teuscher; Sandeep Pathak; Roberto Avolio; Gerardino D’Errico; Giuseppe Vitiell ..., Journal of the American Chemical Society, 2013

Chemical doping is a powerful method to improve the charge transport and to control the conductivity in organic semiconductors (OSs) for a wide range of electronic devices. We demonstrate protic ionic liquids (PILs) as effective p-dopant in both polymeric and small molecule OSs. In particular, we ...
