    Influence of preparation conditions on magnetic properties and aging behavior of rf diode sputtered GdTbCo films (1987)

    Notes: GdTbCo films were rf diode sputtered from a composite target varying the argon pressure PAr and the substrate bias voltage Vb. Both the uniaxial magnetic anisotropy constant Ku and the aging behavior of the films depend strongly on the preparation parameters. The absolute maximum of Ku was obtained at Vb=−150 V. However, at this bias voltage nearly the highest oxidation rate of unprotected 100-nm-thick films was observed. Films of highest stability are obtained without any bias voltage. The oxidation rate is correlated with the Ar concentration in the films. It was argued recently that the anisotropy of sputtered films could depend on argon incorporation. Our results seem to rule out this mechanism since GdTbCo films prepared at zero bias show a relative Ku maximum in dependence on PAr where the argon concentration is near its absolute minimum. The magneto-optic Kerr rotation θK of the films can only be correlated with the Co concentration for zero bias films. Some additional variation depending on the bias voltage has been observed.

    Notes: Synthesis and Polymerization of Unsaturated BenzaldazinesThe preparation of methacrylic and acrylic acid derivatives of isomeric hydroxybenzaldazines and their characterization by u.v.-, i.r.-, 1H and 13C n.m.r. spectroscopy are described. By radical polymerization and copolymerisation with styrene and methyl methacrylate, respectively, crosslinked polymers showing ultraviolet-absorbing properties are obtained.

    Specific binding of basic fibroblast growth factor to basement membrane-like structures and to purified heparan sulfate proteoglycan of the EHS tumor (1988)

    Notes: The binding of iodinated basic fibroblast growth factor (bFGF) to low-density heparan sulfate proteoglycan purified from the Engelbreth Holm Swarm (EHS) sarcoma was investigated using different techniques. The tumor clearly contained bFGF, the level being comparable to that found in other tissues such as human or bovine brain. 125I bFGF strongly bound to the basement membrane-like matrix of EHS frozen sections as revealed by autoradiography. Iodinated bFGF bound to purified heparan sulfate proteoglycan but not to laminin or collagen type IV, three components isolated from the same tumor. In contrast, acidic fibroblast growth factor (aFGF) displayed negligible binding to heparan sulfate proteoglycan. Binding of bFGF to frozen sections and to purified proteoglycan could be strongly inhibited by heparin and was displaced by an excess of unlabeled factor and completely suppressed after heparitinase and heparinase treatments. Binding was a function of the salt concentration and was abolished at 0.6 M NaCl. Scatchard analysis indicated the affinity site had a Kd of about 30 nM, a value 10-15 higher than that recently reported by Moscatelli (J. Cell. Physiol., 131:123-130, 1987) in the case of the low-affinity binding sites present on the surface of baby hamster kidney (BHK) cells.

    Description / Table of Contents: Grafting of styrene or methyl methacrylate on chlorine containing polyesters of 2,2-bis(4-hydroxyphenyl)-1,1,1-trichloroethane is initiated by titanium(III) chloride and chromium(II) acetate/morpholinocyclohexene or vanadium(III) chloride. Analogous, chlorine containing polcarbonates can be grafted. By using styrene, crosslinked graft copolymers are formed. Their formation is influenced by the gel effect. The influences of structure of the backbone chain and grafting conditions have been investigated.
    Notes: Die Pfropfung von Styren oder Methylmethacrylat auf chlorhaltige Polyester des 2,2-Bis(4-hydroxyphenyl)-1,1,1-trichlorethans läßt sich durch Titanium(III)-chlorid und Chromium(II)-acetat/Morpholinocyclohexen oder durch Vanadium(III)-chlorid initiieren. Analog lassen sich chlorhaltige Polycarbonate pfropfen. Mit Styren entstehen vernetste Pfropfcopolymere, deren Bildung durch den Geleffekt geprägt wird. Der Einfluß der Struktur der Rückgratkette und der Pfropfbedingungen wurde untersucht.
