    Mass-transport problems and some design concepts of electrochemical reactors (1974)
    Springer
    Journal of applied electrochemistry 4 (1974), S. 173-190 
    Details
    ISSN: 1572-8838

    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Electrochemical cells, designed to operate with reactants at low concentrations, require special provisions to be made for enhancement of mass transport of the reactants to the electrode surface. The different concepts for doing this in industrial or large-scale cells are reviewed. Examples are given of cells and processes in which these ideas have been used. A comprehensive literature survey of the quantitative relationships pertaining to the different configurations is given. The various cell designs are compared on a quantitative basis, usingi lim, and some advantages and disadvantages are discussed.

    A multi-purpose microprocessor-based electrochemical apparatus (1978)
    Springer
    Journal of applied electrochemistry 8 (1978), S. 437-443 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract A microprocessor-linked programmable calculator instrument is described. Current-voltage readings taken at predetermined intervals of time can be read, stored and passed to the calculator where they may be processed to yield Tafel slope data, ohmic drops, areas under curves (for cyclic voltammetry) or used in open-circuit decay calculations. The results may also be fed to a paper-tape punch for storage or graphplotting using a larger computer.

    The role of electrode structure and surface texture in the performance of gas evolving electrodes (1979)
    Springer
    Journal of applied electrochemistry 9 (1979), S. 765-775 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The literature on gas-evolving electrodes is reviewed. Cell voltage measurements are reported for an undivided cell in NaOH at 70° C in which the cathode was mild steel plate, mild steel mesh or composites of both these materials. The anode was Ni-plated mild steel sheet or mesh. Variation in the structure of one electrode, leaving the other unchanged allowed changes in overvoltage to be measured. It is shown that substantial voltage reductions can be obtained using multiplex electrode structures and that these are mainly explicable in terms of specific surface areas. Sheet electrodes are seen to be more efficient than mesh ones on this basis however. It is shown that sheet electrodes with very high specific surface areas show significantly higher overvoltages than electrodes of low specific area and this surprising result is interpreted in terms of bubble entrapment.

    Current efficiency losses in indirect electrochemical processing (1979)
    Springer
    Journal of applied electrochemistry 9 (1979), S. 777-782 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The various reasons for current efficiency losses in indirect electrochemical processing are considered. Using the Cr(VI) oxidation ofo-toluene sulphonamide as a model, it is shown that accretion of organic residues is an important factor contributing to current efficiency losses. Other evidence is provided to suggest that film formation on the electrode surface acts selectively to promote oxygen evolution rather than Cr(III) re-oxidation.

    Dislocation etching of GaSe single crystals (1971)
    Springer
    Journal of materials science 6 (1971), S. 305-308 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Dislocation etching of GaSe single crystals was investigated by using a dilute chromic-sulphuric acid mixture, when conical etch pits were revealed on the (0001) surfaces. At the apices of spiral growth hills, bunches of spiral dislocations were revealed, proving that it is not a single screw dislocation of large Burgers vector, but a bunch of co-operating screw dislocations that were responsible for the spiral growth formations of large step-height. In the case of GaSe crystals, grown by vapour transport methods, dislocation densities of 102 to 106 cm−2 were found. The Bridgman crystals investigated were completely free from non-basal dislocations.
