    Electrical leakage currents in bipolar cell stacks (1980)
    Springer
    Journal of applied electrochemistry 10 (1980), S. 233-237 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract A brief review of the origins of bipolar leakage currents, the means used for its measurement and calculation and the importance of minimizing the phenomenon, is followed by a novel means of computing leakage currents more accurately than hitherto possible, using a commercially available simulation program. This has the further advantage that the reali-V characteristics of an electrochemical cell can be used, there being no need to represent the cell itself as a zener diode which is a poor representation of reali-V cell characteristics.

    The role of surface texture and anode-cathode size ratios on mass transfer in undivided electrochemical reactors (1980)
    Springer

    ISSN: 1572-8838

    Notes: Abstract The performance of undivided cells with disparate anode-cathode ratios was studied using cerium (IV) reduction as a test reaction. The effects of electrode material and surface texture are reported. Results have been fitted to a computer-based model, and the role of bubble evolution and electrode coverage by bubbles is considered. Results are contrasted with those of a similar study using hypochlorite formation, which can give qualitatively different results.

    Formation of sorbitol by cathodic reduction of glucose (1981)
    Springer
    Journal of applied electrochemistry 11 (1981), S. 261-267 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The steady-state formation of sorbitol by cathodic reduction of glucose was studied in a parallel-plate reactor of 200 cm2 electrode area. Earlier work was extended to explore the effect of flow rate, pH and current density. The effect of temperature between 20° and 47° C and the use of amalgamated lead as compared with chemical lead and other metals is discussed. It is shown that addition of Zn2+ ions accelerates the reaction and the reasons for this are discussed. The implications for industrial application are considered.

    Notes: Abstract Experimental data relating to the performance of a fast flow parallel plate electrochemical reactor are reported, using very dilute reactant solutions. The results are shown to conform to the Chilton-Colburn analogy. The significance of such reactors, in terms of both electrochemical processing and treatment of dilute aqueous effluents, is discussed.

    Notes: Abstract The efficiency of chlorine evolution from dilute brines (0.5–0.1m) was studied on RuO2 and IrO2 coated Ti anodes at 20°C and 70°C. Efficiencies are generally much higher than on graphite electrodes. However at low current densities at 70°C the efficiency on RuO2 is considerably lower than on IrO2.

    pH changes at near-electrode surfaces (1983)
    Springer
    Journal of applied electrochemistry 13 (1983), S. 189-207 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Anodic or cathodic processes in which protons are released or consumed, respectively, lead to local pH changes at the electrode surface. The phenomenon is important in several branches of metal finishing, in corrosion, electro-organic synthesis and other branches of applied electrochemistry, as well as being a factor which can invalidate mechanistic investigations. The concept of ‘pHs’ (near-surface pH) is examined, as are the experimental techniques which have been used to measure it. Many of these are inherently weak. Published results are shown to be largely discrepant, both in respect of the magnitude of the effect and even its incidence. Attempts to treat the phenomenon theoretically are briefly summarized.

    The electrodeposition of copper-silver and copper-nickel alloy powders from aqueous ammoniacal solutions (1984)
    Springer

    Details
    ISSN: 1572-8838

    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The electrodeposition of copper-silver and copper-nickel powders from aqueous ammoniacal solutions at a continuously scraped rotating cylinder cathode is described. Ag-Cu powders can be prepared under these conditions, but the individual particles are inhomogeneous and the extent of this inhomogeneity is examined. Surface areas (from BET) and particle size distributions are reported, and the morphology is considered. Cu-Ni powders deposited under these conditions are heavily contaminated with oxide/ hydroxides and this is attributed to an increase in near-cathode pH.

    Topics: Medicine
    Notes: Summary The action of the non-steroidal antiinflammatory drugs indomethacin, tiaprofenic acid, diclofenac and meclofenamate on vascular and plateletcyclooxygenases was studied by measuring the arachidonic acid-induced thromboxane A2 (TXA2)-formation of washed human platelets and prostacyclin (PGI2)-formation of bovine coronary artery rings. TXA2 was bioassayed as RCS on rabbit aorta strips, PGI2 in terms of its antiaggregatory activity on ADP-induced aggregation of human platelet-rich plasma. All of the substances studied produced concentration-dependent inhibition of PGI2- and RCS-release. The IC50 [μM] in inhibition of RCS-formation was 0.019 for indomethacin, 0.070 for tiaprofenic acid but 44.9 for meclofenamate and 63.2 for diclofenac. The IC50 [μM] in inhibition of PGI2-release was 0.42 for diclofenac, 0.63 for indomethacin and 0.99 for tiaprofenic acid. The data suggest (1) high sensitivity of human platelet-cyclooxygenase against indomethacin and tiaprofenic acid, (2) different sequence of the substances studied in inhibiting arachidonic acid-induced TXA2- and PGI2-formation. The possible therapeutic value of selective inhibition of platelets and vascular cyclooxygenases in discussed.
