    Conformations and time-resolved fluorescence of oligomers of (-)-epicatechin with 4β → 8 interflavan bonds (1991)
    New York : Wiley-Blackwell

    Notes: Oligomers of (-)-epicatechin with 4β → 8 interflavan bonds, and as many as five monomer units, have been studied by conformational analysis and time-resolved fluorescence. The conformational analysis yields 2x-1 conformations for each oligomer with x monomer units. There are two conformations accessible at each interflavan bond. These conformations are denoted by + and -. The dominant conformations for the trimer and higher oligomers have an interaction between the phenolic hydroxyl groups on monomers i and i+2. This interaction involves the hydroxyl group at C(5) on monomer i, and either C(13) or C(8) of monomer i+2, depending on whether the conformation of the two intervening interflavan bonds is + + or + -, respectively. Minor contributions to the ensemble for the tetramer and pentamer are made by conformations that contain the sequence of successive interflavan bonds denoted by -+ or --. In -+ the interaction between monomer units i and i + 2 involves an aliphatic hydroxyl with a phenolic hydroxyl, and there are no hydroxyl-hydroxyl interactions between units iand i + 2 in --. The onset of a different decay law for the fluorescence when x increases from 3 to 4 may be associated with the appearance of the -+ and -- conformations as minor constituents in the ensemble.

    Notes: Thermal and mechanical studies on many linear polyesters have revealed their behavior in crystalline, liquid crystalline, and amorphous phases. Their phase behavior in binary compositions has also been studied by a range of additional techniques and in combinations including the polycarbonate of bisphenol-A. Regions of amorphous compatibility and incompatibility have been identified and measures made of transition temperature changes with composition. The conditions for transreaction have also been determined and the properties measured for the resultant new copolymers.

    Notes: This paper discusses a mathematical model governing the galvanic corrosion phenomenon and surveys the research efforts which have been applied to find a solution to the above problem. The authors classify these techniques into three categories. The first is the finite difference method (FDM), the second is the finite element method (FEM) and the last is the boundary element method (BEM).

    BEM simulation of cathodic protection systems employed in infinite electrolytes (1987)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 24 (1987), S. 605-620

    Notes: This paper describes the proper external potential formulation of a cathodic protection system employed for corrosion prevention of structures in infinite electrolytes. The boundary condition associated with the mathematical formulation is not of the standard type encountered in hydrodynamic, electrostatic or heat transfer applications. The developed mathematical model is discretized by the boundary element technique, which is then solved iteratively by the Newton-Raphson method.

    Notes: Amorphous poly(ethylene terephthalate) has been solid state coextruded to a series of draw ratios up to 4.4 at 50, 60, 70 and 90°C. These uniaxially drawn samples have been examined by optical microscopy and light scattering and for increases in crystallinity and birefringence as a function of draw ratio and draw temperature. The birefringence for PET may be among the highest yet reported - 0.21.

    Evaluation of free and hydrostatic equibiaxial deformation of poly(ethylene terephthalate) by trirefringence measurement (1987)

    Notes: Understanding the deformation behavior of an amorphous thermoplastic, e.g., poly(ethylene terephthalate) (a-PET) and one of semicrystallinity, viz., i-PP, can be is of both fundamental and practical importance. Much has been done to study the influence of temperature and strain, but not the influence of deformation conditions on the three-dimensional orientation of many thermoplastic. In this study we consider the incremental effect of hydrostatic pressure and process geometry on strain-induced deformation. a-PET has been free drawn (i.e., no hydrostatic pressure) isothermally on a tenter frame device. The hydrostatic, equibiaxial deformation was achieved by a forging process involving squeezing between two circular plates. These two processes have been carried out at a series of deformation rates, with the three-dimensional refractive index measurements having been made on the PET and i-PP films using a modified Abbe refractometer, as per Samuels. The reported trirefringence measurement provides a sensitive scale for the planar deformation.

    Melt transcrystallization of polyethylene on high modulus polyethylene fibers (1988)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A polytheylene composite was prepared and tested. It was consisted of a high-density polyethylene (HDPE) matrix and uniaxial gel-spun high-modulus PE fiber. Aided by the similarity between matrix and fiber, transcrystallization of HDPE melt on the PE fiber surface was generated. Nucleating agents were not employed. The transcrystalline growth of HDPE on the PE fiber surface was found to consist of an inner and an outer zone. The inner zone, 2-3 μm thick, is composed of HDPE crystals nucleated on the PE fiber surface. Photomicrographs showed a well-defined region of row-nucleated HDPE on the surface of PE fiber. This means the fibrils of HDPE were found to grow out from the PE fiber axis and HDPE crystallites are oriented in planes perpendicular to the PE fiber axis. The fiber in the composite induced the transcrystalline growth of HDPE on the PE fiber surface at higher temperature than on cooling the melt. For 36 wt% fiber, the increase was 2.5°C, also resulting in ∼ 10% more crystals. Crystallization of a composite with 50 wt% fiber at 124°C involved two steps: The first a fast transcrystallization of HDPE on the PE fiber surface followed by the bulk crystallization of the HDPE.
