    Notes: A modification of van der Waals and Platteeuw's (1959) hydrate equilibrium model which incorporates the effect of spherical asymmetry is developed. A corresponding states correlation is used to predict the deviation of Langmuir constants from ideal values. In this model the Kihara parameters obtained from hydrate equilibrium data agree well with those obtained from virial coefficient data.

    Theory on colloidal double-layer interactions (1984)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The potential energy between two interacting colloidal particles is derived by a knowledge of the energy of interaction of two parallel flat plates. The proposed method maps pairs of infinitesimal surface elements from the two interacting bodies to parallel plate-like elements. The results obtained from this theory are compared with the Derjaquin approximation for large kR and the Levine and Dube approximation for small kR.

    Notes: Asymmetric Michael addition of lithiated methyl ketone SAMP hydrazones (S)-3 to a variety of alkenylphosphonates (E)-2 followed by oxidative cleavage of the 1,4-adducts (S,S)-4 by ozonolysis afforded 2-substituted 4-oxophosphonates (S)-5 in usually moderate to very good overall yields (14-77%) and with mostly high enantiomeric excesses (ee = 20-〉95%). In addition, asymmetric Michael Michael tandem additions were carried out in good overall yields by trapping the intermediate lithio phosphonate anions with alkenylphosphonate or enoate Michael acceptors.

    A method for measuring bacterial chemotaxis parameters in a microcapillary (1996)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 51 (1996), S. 120-125 
    Details
    ISSN: 0006-3592
    Keywords: chemotaxis ; single cell ; capillary ; Escherichia coli ; Chemistry ; Biochemistry and Biotechnology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A new method was developed which enables chemotaxis parameters to be measured at a single-cell level inside a capillary for the first time. The chemotaxis chamber consists of two reservoirs communicating through a capillary tube 50 μm in diameter. Chemotaxis parameters are measured inside the capillary using image analysis, after a nearly linear attractant concentration gradient has been generated along the capillary by diffusion. Compared to previously published techniques, this method provides a well-characterized chemoattractant concentration profile in addition to allowing single-cell parameters to be measured inside a fine capillary. This procedure was used to measure the single-cell chemotaxis parameters for Escherichia coli K12, and the results are compared to published data on single E. coli cells chemotaxing in bulk. © 1996 John Wiley & Sons, Inc.

    Bacterial motility, collisions, and aggregation in a 3-μm-diameter capillary (1997)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Motility of Escherichia coli K-12 cells was studied in a capillary tube with an inside diameter of 3 μm, which is comparable to the size of the cells' body. The extreme restriction, imposed by the capillary on the bacterial motility, caused a series of phenomena such as cell aggregation, swimming as a cluster, and break-up of aggregates, which were observable for the first time, and which are reported here. © 1997 John Wiley & Sons, Inc.

    Description / Table of Contents: Rearrangements of 2,3-Diazabicyclo[2.2.2]octane DerivativesThe ketones 4a - e have been synthesized and their reactions with methylmagnesium iodide were studied. A mechanism is given for the rearrangement of some magnesium alkoxides to 6,7-diazabicyclo[3.2.1]octane derivatives. - Dehydration of the alcohols 12d, 14a; 17a, b, g, and h with trichlorophosphane oxide is accompanied by migration of the group antiperiplanar to the hydroxy function, and thus 6,7-diazabicyclo[3.2.1]octane derivatives are formed. - Ketones 4a, c and e give on sensitized irradiation the tricyclooctane derivatives 40a, b and d, respectively, while direct irradiation leads to the bicycloheptane derivatives 42a, b and d, respectively.
    Notes: Die Darstellung der Ketone 4a - e sowie deren Umsetzung mit Methylmagnesiumiodid werden beschrieben. Für die bei einigen dieser Grignard-Additionen auftretende Umlagerung zum 6,7-Diazabicyclo[3.2.1]octan-System wird ein Mechanismus aufgestellt. - Die Dehydratisierung der Alkohole 12d, 14a, 17a, b, g und h mit Trichlorphosphanoxid erfolgt unter stereokontrollierter Umlagerung zum Bicyclo[3.2.1]octan-System mit Wanderung der zur Hydroxyfunktion antiperiplanaren Gruppierung. - Je nach Belichtungsbedingungen erhält man bei der Photoisomerisierung von 4a, c und e die Tricyclooctan-Derivate 40a, b bzw. d oder die Bicycloheptan-Derivate 42a, b bzw. d.

    Static and frequency dependent polarizabilities and hyperpolarizabilities of H2Sn (1998)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Computational Chemistry 19 (1998), S. 1698-1715

    Notes: The structure-polarization relationship was investigated in a series of polysulfanes, H2Sn. The reported results demonstrate that the forms of change of the polarizability components, αii, and the second hyperpolarizability components, γiiii, as well as the average values α and γ, respectively, of H2Sn with n are similar. This shows that polarizability components can be easily used to determine corresponding hyperpolarizability data. A remarkable change of the hyperpolarizabilities with the molecular geometry of H2Sn was found. This result can be used for the design of nonlinear optical materials with optimum properties. The present study uses the flexible σ bonded H2Sn and is complementary to the works that considered the effect of conformational changes of π-conjugated systems on their hyperpolarizabities. The present computations were performed using the semiempirical approaches MNDO and MNDO/d, as well as ab initio methods with STO-3G, extended with polarization and diffuse functions, and [3s2p/7s5p2d] sets for H2Sn. At the ab initio level, the electronic and the vibrational contributions to polarizabilities and hyperpolarizabilities were both computed for several members of H2Sn. The frequency dependence of the above contributions and the static limit were discussed. Electron correlation was taken into account for several test cases using MP2 theory. The selected methods and the variety of the approximations on which they rely allow the systematic consideration of the effect of changes of the geometry of H2Sn on their polarizabilities and second hyperpolarizabilities.   © 1998 John Wiley & Sons, Inc.   J Comput Chem 19: 1698-1715, 1998
