    Air oxidation of S(IV) in cloud-water samples (1995)
    Springer
    Water, air & soil pollution 85 (1995), S. 1985-1990 
    Details
    ISSN: 1573-2932
    Keywords: cloud-water ; sulphur dioxide ; oxidation ; catalysis ; trace metals ; iron ; acidity ; pH
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Aerobic oxidation of S(IV) was investigated in cloud-water samples collected at Great Dun Fell,U.K., as part of a wider project into cloud-water chemistry. The rate was found to be first-order in S(IV) concentration, and the reaction rate constant. kS(IV), was found to vary from 10−5 to 10−3 s−1. The rate constant was highly correlated with H+ concentration (pH 3.5 to 6.5) and Fe concentration (〈0.02 to 3×10−6 mol dm−3). The aerobic oxidation of S(IV) does not contribute significantly to SO2 oxidation in clouds at Great Dun Fell, however, the reaction may be of consequence in clouds and fogs at polluted or urban sites with elevated trace metal concentrations. Also, this reaction may be responsible for the oxidation of S(IV) in cloud-water samples during storage.

    Variations between Biomer™ lots. I. Significant differences in the surface chemistry of two lots of a commercial poly(ether urethane) (1992)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 26 (1992), S. 273-289 
    Details
    ISSN: 0021-9304
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Medicine , Technology
    Notes: We have studied the surface chemistry of two lots of Biomer™ (BSP067 and BSUAOOl), and widely used commercial poly(ether urethane) (PEU). Although transmission infrared adsorption studies revealed no differences in the bulk chemistry of the two lots, the surface chemistry, as seen by x-ray photoelectron spectroscopy (XPS) and static secondary ion mass spectrometry (SIMS), was different. Lot BSP067 showed softsegment enrichment at the surface, which is typical of PEU. Lot BSUAOOl showed no evidence of either hard- or soft-segment PEU components at the surface. The surface of this lot was completely covered with a nonextractable additive identified as poly(diisopropy1 amino ethyl methacrylate). Small amounts of a low-molecular-weight antioxidant were observed at the surface of both samples. Because the biological response to polymers is dependent on surface structure, these results are of considerable importance to biomaterials research.

    Regularization: A stable and accurate method for generating depth profiles from angle-dependent XPS data (1989)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 14 (1989), S. 443-450 
    Details
    ISSN: 0142-2421
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Physics
    Notes: An algorithm for generating depth profiles from angle-dependent XPS data has been developed. The algorithm uses the regularization method with non-negativity constraints. Four criteria for determining the optimal amount of solution smoothing have been investigated. A criterion that uses the least-squared error in the regenerated data set proved most effective for selecting the optimal smoothing. Simulated data for a two-layer sample were used to investigate the effects of the number of data points, where each data point consisted of the spectra acquired at a take-off angle. Simulated data were also used to investigate the effect of random error on the calculated depth profiles. Increasing the number of data points improved the resolution at the interface. Greater than 10% error could be added to the data without affecting the stability of the algorithm. The algorithm has also been tested on actual angle-dependent XPS data sets from a thin polyurethane film on gold, a thin silicon oxide film on silicon, and a thick polyetherurethane film on glass. Performance of the regularization algorithm has been compared to an algorithm that uses a singular value decomposition of angle-dependent XPS data to generate depth profiles. The regularization algorithm demonstrates significantly improved stability and accuracy with roughly equal computational difficulty. Using the regularization algorithm, a quantitative estimate of the depth profile in the upper 100 Å region of a sample can be calculated using data with 〉 10% error and using as few as three data points.

    Hazard assessment techniques used in the chemical industry and their possible uses elsewhere (1984)
    New York, NY [u.a.] : Wiley-Blackwell
    Fire and Materials 8 (1984), S. 199-205 
    Details
    ISSN: 0308-0501
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Architecture, Civil Engineering, Surveying , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The traditional methods used for the identification and assessment of hazards in the chemical industry are based on experience, but increased economic and environmental restrictions on its operations have required the development of other methods to ensure that an acceptable level of safety is maintained. The present paper briefly reviews the traditional methods, describes in mire detail the basis of the newer methods, namely hazard and operability studies and hazard analysis, and considers how they might be more widely used in assessing fire hazards.

    The correction of rate data for the effects of internal temperature change (1974)
    New York, NY : Wiley-Blackwell
    International Journal of Chemical Kinetics 6 (1974), S. 531-543 
    Details
    ISSN: 0538-8066
    Keywords: Chemistry ; Physical Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The effect of reactant self-heating or cooling upon rate data is considered, and three approaches to the problem of obtaining valid kinetic parameters are described in detail. A comparison of these approaches emphasises the need to assess and allow for thermal effects during the initial planning of kinetic experiments if satisfactory results are to be acquired. An integrated rate expression is given for use with nonisothermal data, and is used to provide correction factors for rate constants which have been derived without allowance for thermal effects.
