    Notizen: Atomic force microscopy (AFM) images taken from an Fe-arachidate Langmuir-Blodgett film irradiated with 23 MeV fullerene ions gives clear evidence that craters are formed as a result of the cluster-ion impact. The crater diameter fits into a systematic formula already found for atomic ions. The AFM images indicate that even the largest molecular ions desorbed stem from the crater volume.

    Notizen: On the Telomerization of Isoprene at Low TemperatureThe telomerization of isoprene was carried out by means of a catalyst system of Pd(acac)2/PPh3 and complexes of the type Pd(acac)2 · L (L = PPh3; py; NHEt2) at 298 K. The reaction in methanol gave 8-methoxy-2, 7-dimethyl-octa-1, 6-diene (3a), 8-methoxy-3, 7-dimethyl-octa-1, 6-diene (4a) and oligomer products. 2, 7-Dimethyl-octa-1,3, 7-triene (1), 8-i-propoxy-2, 7-dimethyl-octa-1, 6-diene (3b) and oligomer products were obtained in i-PrOH. During the reaction a formation phase of the catalyst was observed.

    Potentiometric titration curves of oxidized and reduced horse heart cytochrome c (1980)
    New York : Wiley-Blackwell
    Biopolymers 19 (1980), S. 885-898 
    Details

    Thema: Chemie und Pharmazie
    Notizen: Potentiometric titration curves of oxidized and reduced horse heart cytochrome c in 0.15M KCl at 20°C have been obtained by timed titration (0.125-0.500 μmol/sec) from the isoionic points (pH 10.2-10.4) to pH 3 and back to the isoionic point. Computer-assisted (PROPHET) data acquisition and blank corrections give curves with good precision with a maximum standard deviation of 0.3 groups for an average error of 1%. The potentiometric titration curve of reduced cytochrome c is reversible within the precision of the method and for the pH range studied. The potentiometric curves for oxidized cytochrome c titrated upscale (pH 3-10) and downscale (pH 10-3) are not reversible. However, they show the same ionization behavior after the initial downscale titration. This is probably the result of a conformational change. Comparison of the data herein reported with the titration curves of oxidized cytochrome c already published by others indicates good agreement on the basis of a normalization of the concentration of protein or on the basis of 25 titrable groups between the acid end point and the isoionic pH.Titration of the 2 μmol imidazole in the upscale or downscale direction gives the correct analytical concentration and pK′ after correction for the solvent titration. Titration of reduced cytochrome c in the presence and absence of an additional equivalent of imidazole gave a difference titration curve, which indicates that a group on the protein shifts from pK′ 5.8 to pK′ 5.3 in the presence of imidazole. The pK′ of imidazole, in the presence of the protein, remains at a nearly normal value of 7.34.

    Calorimetric determination of the enthalpy of ionization of oxidized and reduced horse heart cytochrome c (1980)

    Notizen: The heats of ionization of protons, ΔHi, of oxidized and reduced horse heart cytochrome c in 0.15M KCl at 20°C were determined using a titration calorimeter which simultaneously afforded the potentiometric titration curve. Reproducibility of the thermal titrations is within 2%, and evaluation of the heats observed after the heat loss corrections is estimated to be within 5%. A single titration of oxidized cytochrome c from pH 11 to 3 is in excellent agreement with the thermal titration of this protein obtained with flow calorimetry. The thermal titration, however, is not reversible, due in part to the loss of titratable group(s) in this pH region and to the heat contribution of the acid and alkaline conformational changes which occur. Although of lesser magnitude, the reduced form also indicates similar thermal transitions. These differences are due solely to conformational contributions to the thermal process, since the potentiometric curves are reversible. The nature of the irreversibility for oxidized cytochrome c appears to involve the loss of a group with pK′ 8.9 and the shift of two groups from pK′ 5.6 to 4.8. Thermal difference curves for this process indicate that heats of -7.8 and -24.1 kcal/mol are liberated which are centered at pH 9.3 and 3.9, respectively.

    Analysis of the ionization constants and heats of ionization of reduced and oxidized horse heart cytochrome c (1981)
    New York : Wiley-Blackwell

    Notizen: Simultaneous curve fitting for the ionization parameters of oxidized and reduced horse heart cytochrome c in 0.15M KCl and 20°C yields values for the ionization constants (as pK′) and the heats of ionization (ΔHi) which can reconstruct either the potentiometric or thermal titration curves. Reduced cytochrome c requires 8 sets of groups, whereas oxidized cytochrome c requires 10 sets of groups. The additional groups in the oxidized preparation appear to involve the ferriheme (pK′, 9.25; ΔHi, 13.7 kcal/mol) and a tyrosine (pK′ ≃ 10.24) that is not present in the reduced form. The potentiometric and thermal difference curves (reduced - oxidized) involve the appearance of 17 kcal/mol centered at pH 9.7 and 5.8 kcal/mol centered at pH 4.9. The carboxyl groups in both species appear to be normal for the hydrogen-bonded form. Only one histidine has normal ionization properties (pK′, 6.7; ΔHi, 7.5 kcal/mol), as do 17 of the lysine residues (pK′, 10.8; ΔHi, 11.5 kcal/mol).

    Free-surface flow over curved surfaces: Part I: Perturbation analysis (1998)

    Notizen: The standard two-dimensional shallow water equation formulation assumes a mild bed slope and no curvature effect. These assumptions limit the applicability of these equations for some important classes of problems. In particular, flow over a spillway is affected by the bed curvature via a decidedly non-hydrostatic pressure distribution. A detailed derivation of a more general equation set is given here in Part I. The method relies upon a perturbation expansion to simplify a bed-fitted co-ordinate configuration of the three-dimensional Euler equations. The resulting equations are essentially the equivalent of the two-dimensional shallow water equations but with curvature included and without the mild slope assumption. A finite element analysis and flume result are given in Part II. © 1998 John Wiley & Sons, Ltd.
