In Situ Infrared Spectroelectrochemistry( Book )

3 editions published in 1986 in English and held by 3 WorldCat member libraries worldwide

In situ infrared (IR) spectroelectrochemistry has become a viable experimental technique only within about the past five years, but it has already proved to be an important addition to the small number of in situ spectroelectrochemical methods currently in use (electron spin resonance spectrometry, ellipsometry, UV-visible spectrometry, resonance Raman, and surface-enhanced Raman spectrometry), . The technique has found two broad areas fo application. Keywords: Spectroelectrochemistry, Infrared radiation
The Behavior of the Infrared Spectrum of Carbon Monoxide Adsorbed at Platinum Electrodes from Non-Aqueous Solvents( Book )

2 editions published in 1988 in English and held by 2 WorldCat member libraries worldwide

The infrared spectrum of Carbon Monoxide adsorbed on a platinum electrode from several solvents was investigated. In N-methylformamide, acetonitrile, and 1,2-dichloroethane, the infrared band attributed to linear bonded CO had experimental Stark tuning rates of 20/cm/V, 22/cm/V, and 19/cm/V, respectively. For each of these solvents, the potential dependence of the band position was found to be linear for the entire potential range investigated. When methanol was the solvent, the plot of the band position versus potential had three distinctly linear portions, each with a different value for the slope. The behavior is explained in terms of the ability of the solvent molecules to closely approach the electrode surface, the polarity of the solvent, and the orientation of solvent molecules with respect to the polarization of the electrode.

The theory of orthogonal collocation as applied to rotating disc systems is presented and its advantages are described. The technique is extremely fast and application of chemical reactions is easily implemented. (Author)
Comparisons between Surface-Enhanced Raman and Surface Infrared Spectroscopies for Strongly Perturbed Adsorbates: Thiocyanate at Gold Electrodes( Book )

2 editions published between 1985 and 1986 in English and held by 2 WorldCat member libraries worldwide

The potential-dependent C-N stretching mode, v sub CN, for thiocyanate adsorbed at the gold-aqueous interface is examined by both surface- enhanced Raman spectroscopy (SERS) and subtractively normalized interfacial Fourier transform infrared spectroscopy (SNIFTIRS). Both SERS and SNIFTIRS exhibit a v sub CN frequencies were very similar (within ca. 5/cm) for the SNIFTIRS at smooth and electrochemically roughened gold, as well as for SNIFTIRS and SERS on the latter surface. This suggests that the SERS-active sites do not differ substantially from the preponderant sites sensed by SNIFTIRS. Some features of the SER spectra suggest that N- as well as S-bound adsorbed thiocyanate exists at far negative potentials
Electrochemical Studies on Minoxidil and Its Determination in Tablets by Differential-Pulse Polarography( Book )

2 editions published in 1984 in English and held by 2 WorldCat member libraries worldwide

A simple differential-pulse polarographic (D.p.p.) method has been developed for the analysis of minoxidil in pharmaceutical dosage forms. The extracting solvent was methanol and the supporting electrolyte was 1.0 N sulphuric acid. An excellent linear relationship was obtained between concentration and current peak height with a correlation coefficient of 0.9999. Good agreement was obtained between results with the d.p.p. method and those by the manufacturer's method of assay. There was no interference by the tablet excipients. In acid solution, a mechanism for reduction at -1.2 V is proposed which involves four electrons transferred as well as dehydration and deamination steps. (Author)
Interfacial Infrared Vibrational Spectroscopy( Book )

2 editions published in 1986 in English and held by 2 WorldCat member libraries worldwide

Vibrational spectra of species on or near metal surfaces are subject to a unique surface selection rule due to the physics of reflection of radiation from a highly conducting surface. As shown in Fig. 1, s-polarized radiation (electric vector perpendicular to the plane of incidence) at all angles of incidence undergoes a phase shift close to 180 C. P-polarized radiation (electronic vector in plane of incidence) has a phase change upon reflection which varies with the angle of incidence as also shown in Fig. 1. Light reflected from a metal surface combines with the incident light to form a standing wave electric field whose intensity is shown in Fig. 2. The mechanism for absorption of infrared radiation requires a coupling of the electric field with a molecular vibration. Since the intensity of the standing wave electric field parallel to the surface is near zero, only those modes of a species near the metal surface which produce a fluctuation in the dipole moment with component normal to the surface can absorb energy
The Behavior of Microdisks and Micoring Electrodes. Prediction of the Amperometric Response of Microdisks and of the Steady State for c.e. and e.c. Catalytic Reactions by Application of Neumann's Integral Theorem( Book )

2 editions published in 1988 in English and held by 2 WorldCat member libraries worldwide

It is shown that the chronoamperometric response at microdisk electrodes can be derived from Neumann's integral theorem of two parameters. The form of the transients can be predicted for a wide range of boundary conditions and this is illustrated by the relaxation behavior of irreversible reactions in addition to that of the widely investigated example of zero surface concentration of the reactant. Corrections to the transients due to the tertiary current distribution are derived for relaxation experiments and it is shown that the methods developed can also be applied to linear sweep voltammetry. The steady state behavior of c.e. and e.c. catalytic reactions is formally similar to the chronoamperometry of irreversible electrode reactions and it is shown that complete descriptions can be obtained for the voltammetry of such systems. Keywords: Mass transport, Electrochemistry. (AW)
Modulated Surface Vibrational Spectroscopies at Electrode/Electrolyte Interfaces by Stanley Pons( Book )

2 editions published in 1984 in English and held by 2 WorldCat member libraries worldwide

In this report, we will discuss the applicability of a new infrared vibrational probe to studies of the structure and orientations of molecular species at or near the electrode-solution interface and the dynamics of adsorption/desorption processes. Such studies have been virtually impossible with available instrumentation in the past due to the extremely large absorbance by the solvent/electrolyte system. Early investigations on electrochemical systems were thus attempted primarily with internal reflectance methods that did not require that the radiation pass through the bulk solvent/electrolyte system. This method is limited, however, due to the few choices of infrared-transport electrode materials (semiconducting materials or very thin metal films on insulating transparent salts and polymers) in addition to more stringent cell designs and electrode geometries

Ultramicroelectrode Sensors and Detectors. Considerations of the Stability, Sensitivity, Reproducibility, and Mechanism of Ion Transport in Gas Phase Chromatography and in High Performance Liquid Phase Chromatography( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

We describe in this paper the use of ultramicroelectrodes as sensitive sensors and detectors in the gas phase and in liquid solutions of high resistance; particularly aspects regarding the sensitivity, stability, and reproducibility of the devices. The advantages of these detectors can be improved notably by appropriate choice of method of pretreatment of the electrode surface. The surface separating the working ultramicroelectrode from the secondary/reference electrode provides the medium for ionic conduction for the cell. The mechanism for ion conduction involves proton migration and diffusion across the surface of the separator. (aw)
Horizon by Deborah Cadbury( Visual )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

In 1989, Professors Martin Fleischmann and Stanley Pons announced that they had discovered the secret of endless, cheap energy by perfecting nuclear fusion in a test tube. Their discovery was dismissed with contempt by the scientific establishment and they fled their academic posts in the USA. The programme suggests that the Japanese are now poised to invest heavily in Fleischmann and Pons' latest work, while advocates of cold fusion warn that the West has missed out on the discovery of the century
A Conducting Polymer Formed from the Anodic Oxidation of Toluene in Acetonitrile( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

As opposed to the much harsher conditions demanded in homogeneous solutions, a conducting polymer of toluene is readily formed by anodic oxidation of acetonitrile solutions containing the precursor. The fabrication of new conductive polymers is of interest due to the potential practical applications of these materials. We report here the electrochemical polymerization of a conducting polymer from toluene precursor. Anodic oxidation of concentrated solutions (0.5 M) toluene in anhydrous acetonitrile solution containing 0.15 M Bu4N+BF4-leads to the formation of a highly conductive poly(methylphenylene) polymer film on the surface of a platinum mirror electrode (bulk metal). The polymer can also be formed in solutions of lower concentrations (1-10 mM), but only after successive pulsing or sweeping techniques at high positive potentials (>1.8 vs Ag/Ag+) for long periods of time. Keywords: Phenylenes, Methyl radicals, Silver. (MJM)
The Behavior of Disk Electrodes: Optical Imaging of the Concentration Distribution over a Disk Electrode under Galvanostatic Conditions( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

This paper describes the theoretical and experimental determination of the integrated time dependent concentration distribution of an electrogenerated species over a disk electrode embedded in an insulated plane. We have derived this result for case of constant applied flux (chronopotentiometry). The experimental technique used for observing the integrated concentration distribution over the electrode was imaging by a low noise charge coupled device camera with time and spatial resolution of approximately 20 ms and 20 micrometers respectively. The experiment demonstrates the contribution of the tertiary current distribution across the surface of the electrode. Keywords: Charge coupled devices; Electrogeneration; Real time. (JHD)
An Electrochemical and UV-Visible Spectroelectrochemical Investigation of Selectivity of Potentiometric Gas Sensors Based on Polypyrrole( Book )

1 edition published in 1986 in English and held by 1 WorldCat member library worldwide

It has been shown in previously that a suspended gate field transistor (SGFET) can be used as a general device for sensing of gases and dielectric fluids. The principles of operation of this device is based on chemical modification of the electron work function of a chemically selective layer which is electrochemically deposited within the gate structure of the device. Electropolymerized polypyrrole (PP), one such layer, can be used as a general matrix into which other chemical functionalities can be incorporated in order to change its selectivity. It has been shown that other organic compounds can be incorporated electrochemically into the bulk of the PP film or that its surface can be covalently modified. Furthermore, PP forms an ohmic junction at noble metal electrodes which is important for the proper operation of the device. In this paper we shall describe the correlation between the spectroelectrochemical characteristics of various types of layers based on PP with their sensitivity and selectivity to some aromatic and hydrogen bonding compounds that interact with the film by hydrogen bonding oar through aromatic systems
An In Situ Surface Fourier Transform Study of Complexes of Lithium, Magnesium Potassium, and Lanthanum Ferrocyanide at Platinum and Gold Electrodes( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

The working electrode was either a platinum or gold disk (1 cm diameter), which had been polished to a mirror finish using progressively smaller diameters of alumina down to 0.05 micro meters. The disk was mounted on the end of a glass syringe barrel designed to fit the infrared cell. The cell construction was of the thin layer type and has been described previously. A platinum wire quasi-reference electrode was used throughout these experiments. The spectrometer employed was a vacuum bench Brucker-IBM model IR/98 FTIR on which subtractively normalized interfacial Fourier transform infrared spectroscopy (SNIFTIRS9) could be performed. In SNIFTIRS difference spectra, the data are displayed so that bands extending to positive (upwards) values of relative reflectance are due to species at the base reference potential ('reactants' in the unperturbed system), while negative bands denote species formed when the potential is stepped to a new value (the 'products' of the electrochemical reaction).

An Electrochemical and Raman Spectroelectrochemical Investigation of Underpotentially Deposited Silver on a Gold Substrate( Book )

1 edition published in 1986 in English and held by 1 WorldCat member library worldwide

Electrochemical and spectroelectrochemical data indicate that underpotentially deposited silver adatoms on gold substrates are photolyzed to form silver metal clusters. The surface gold-gold stretch and gold-silver stretch bands are observed, as well as the surface chloride complex stretch. The chloride complex interacts with ions in the solution phase giving rise to shifts in the metal-chloride stretching vibrational frequency as a function of the applied electrode potential. However, the metal metal bands are more dependent on the electric field at the electrode surface
