    AIChE Journal 22 (1976), S. 794-798

    Notes: A potentially simple and effective technique is proposed for separating enantiomorphic crystal pairs from each other, or separating individual enantiomorphs from optically active impurities.This method consists essentially of settling under conditions controlling orientation of the asymmetric particles and taking advantage of the tensorial nature of their friction factors.

    Mass transfer to falling films: Part I. Application of the surface-stretch model to uniform wave motion (1968)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 14 (1968), S. 458-467

    Notes: A method is developed for predicting rates of gas absorption into laminar rippling films in terms of the surface velocities. The description is an extension of the surface-stretch model of mass transfer (1) and is therefore useful for cases of high Peclet number. The description can be used with any of the presently known hydrodynamic models of rippling films and with any future models which may be developed, provided they satisfy two relatively nonrestrictive conditions: (1) the ripples are of a two dimensional nature, being of constant thickness in the direction normal to their direction of propagation, and having no velocity components in this transverse direction; and (2) the ripples propagate at constant celerity and with constant shape. It can be used for both traveling and standing waves and can be extended to describe the effects of high net-mass transfer rates and combined diffusion and chemical reaction.

    Electrochemistry of hexacoordinate silicon(IV) porphyrin complexes (1997)
    Weinheim : Wiley-Blackwell
    Electroanalysis 9 (1997), S. 1273-1277

    ISSN: 1040-0397
    Keywords: Cyclic voltammetry ; Porphyrins ; Silicon ; Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: Cyclic voltammetry was used to characterize the oxidation-reduction behavior of a series of novel hexacoordinate silicon(IV) porphyrin complexes. Each (Por)SiX2 [Por = the dianions of the porphyrins: tetrakis(p-tolyl)porphyrin (TTP), tetraphenylporphyrin (TPP), tetrakis(p-trifluoromethylphenyl)porphyrin (TTFP), octaethylporphyrin (OEP), × = F, Cl, O3SCF3] complex undergoes one to two oxidations and one to two reductions, all occurring at the porphyrin ring. No silicon(IV) reduction is observed for any of the porphyrin complexes. The effects of solvent, supporting electrolyte, substituents on the porphyrin ring, axial ligands, certral metal, and ruffling of the porphyrin ring are described.

    Voltammetry and LCEC of isoflavones (1997)

    Notes: This study provides electrochemical and LCEC determination for three of the most abundant and most important isoflavones, Biochanin A, formononetin, and genistein. Cyclic voltammetry and pH-potential diagrams show that the isoflavones undergo pH-dependent irreversible oxidations. The LCEC determination of the isoflavones has been optimized for mobile phase composition and detection potential. Sub-nanogram detection limits have been achieved.

    A reticulated vitreous carbon spectroelectrochemical detector for flow injection analysis and liquid chromatography (1992)
    Weinheim : Wiley-Blackwell
    Electroanalysis 4 (1992), S. 487-493

    ISSN: 1040-0397
    Keywords: Spectroelectrochemistry ; reticulated vitreous carbon ; detector ; Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A spectroelectrochemical detector for flow injection and liquid chromatography is described. The detector design has dimensions of a standard 1 cm sample cuvette with a replaceable reticulated vitreous carbon working electrode. No special cell holder or modifications to the spectrophotometer are required to use the detector. Chronocoulometry is used to indicate a trend from thin-layer behavior toward semi-infinite diffusion behavior as the electrode pore size increases. Ferro-/ferricyanide solutions were used to evaluate the flow injection characteristics of the detector. A sampling rate of 180 injections per hour was used. Linear calibration curves in the micromolar range were achieved with a reproducibility of 2-7%. A mixture of phenol, chlorophenols, and nitrophenols was used to investigated the simultaneous electrochemical and optical response for liquid chromatography.
