    Notes: The magnetic properties of [Fe(20 A(ring))/Pd(x A(ring))]25 multilayers prepared by ultrahigh vacuum electron-beam evaporation are presented. It is found that the crystal structure of Fe layers change from bcc to fcc when the thickness of Pd layers dPd≥36 A(ring). The saturation magnetization per unit Fe volume at 5 K is enhanced and oscillates with the increment of the thickness of Pd layers, due to the polarization of Pd atoms. The magnetic hysteresis loops of samples indicate low coercive forces, and ferromagnetic coupling between the Fe layers for all Pd thicknesses (6–60 A(ring)). The conversion electron Mössbauer spectra measurements proved that the magnetic moment of fcc Fe is the same as that of the bcc Fe. It is also found that the magnetic anisotropy dependence on dPd is similar to that of the saturation magnetization, and relates to the Fe layer structure transition. The Curie temperature of Fe/Pd multilayers decreases monotonously with the increasing of dPd. The low temperature magnetization measurement of Fe/Pd multilayers suggests that the interlayer coupling between Fe layers and polarization of Pd layers influences the temperature dependence of saturation magnetization. No evidence of antiferromagnetic coupling between Fe layers and giant magnetoresistance effect is found. The relationship among structure, polarization of Pd layers, and magnetic coupling is discussed. © 1995 American Institute of Physics.

    Orange-green emission from porous Si coated with Ge films: The role of Ge-related defects (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 86 (1999), S. 707-709

    Notes: Photoluminescence (PL) spectra of porous Si (PS) coated with Ge films were examined using the 514.5 nm line of Ar+ laser. A new orange-green PL band, centered at 2.25 eV, was observed with full-width at half-maximum of ∼0.1 eV, in addition to the reported PL bands at 3.1, 2.0, and 1.72 eV. With increasing the thickness of Ge layer coated, the new PL band remains unchanged in peak energy but drops abruptly in intensity. Spectral analysis and some experimental results from Raman scattering and x-ray diffraction indicate that Ge-related defects at the interfaces between PS and the Ge nanocrystals embedded in the pores are responsible for the orange-green PL band. © 1999 American Institute of Physics.

    Charge-separated state in strain-induced quantum dots (1997)

    Topics: Physics
    Notes: We have measured the time-resolved photoluminescence of strain-induced quantum dots. We show that a long-lived intermediate state is involved in the excitation transfer from the interstitial quantum well to the dot. This intermediate state has the properties expected of the charge separated state predicted by theory. © 1997 American Institute of Physics.

    Notes: The discovery of oscillatory interlayer exchange coupling in a new type of ceramic superlattice system Fe–N/TiN, is reported. The magnitude of the exchange coupling was found to oscillate with the thickness of the TiN spacer layer and Fe–N ferromagnetic layer with periods about 0.8 and 0.6 nm, respectively. © 1996 American Institute of Physics.

    Induction of apoptosis in proliferating lymphocytes by tricyclic antidepressants (1998)

    Notes: Abstract We have previously found that tricyclic antidepressants (TCAs) induce apoptosis in quiescent human lymphocytes. The aim of the present study was to evaluate if TCAs induce apoptosis in proliferating human lymphocytes and in established blastoid lymphocytes also. The development of conA-induced lymphoblast populations was followed by measuring the CD25 membrane expression. Three TCA compounds were run with the following concentrations: imipramine (10, 20, 30, 40, 60μ M), clomipramine (1, 10, 20, 30, 40μ M) and citalopram (40, 60, 80, 100, 180μ M). They all induced a dose-dependent apoptosis both in continuously transformed, as well as in established lymphoblasts. Preincubation of the TCA up to 48 h did not significantly increase induction of apoptosis. The three drugs tested were found to be potent inducers of apoptosis in proliferating lymphocytes. Furthermore, we found that the apoptotic populations in proliferating and in established blastoid lymphocytes were of f airly the same magnitude than in the corresponding population in TCA-incubated resting lymphocytes. In conclusion, we demonstrate that TCAs induce apoptosis in proliferating lymphocytes, as they do in quiescent lymphocytes. Furthermore, the exent of apoptosis was even more pronounced in TCA-incubated lymphoblasts compared to TCA-treated resting lymphocytes.

    Notes: Abstract We have obtained results for converting focused laser radiation to X-ray line emissions in laser-heated NaF and Cu plasmas. These plasmas were used as the pump source for studying the phenomena of inner-shell photoionization of Zn-like ionic states. Soft X-ray emissions from transitions of 3d 94s 2 → 3d 104p in Cu-like Pd and Ag ions were observed.

    Lily cofactor-independent phosphoglycerate mutase: purification, partial sequencing, and immunolocalization (1996)
    Springer

    ISSN: 1432-2048

    Notes: Abstract A cofactor-independent phosphoglycerate mutase (PGAM-i) was isolated to homogeneity from monocotyledonous Lilium longiflorum Thunb. Two-dimensional (2D) polyacrylamide gel electrophoresis resolved three PGAM-i forms. This enzyme was originally identified by cross-reactivity to antibodies affinity-purified from 2D gels using human vitronectin (VN). Antibody produced against a denatured protein spot from a 2D gel did not recognize VN protein, but partial protein and DNA sequencing showed similarity of the former protein to maize PGAM-i. Immunoblots from roots, styles, leaves, and anthers showed the presence of PGAM-i in all tissues examined; it was isolated predominantly from the soluble cell fraction, with some present in the insoluble cell fraction. Immunoelectron microscopy demonstrated its localization in the cytoplasm and plastids in root cells near the apical meristem. In addition, immunogold labeling detected signals from the nucleus. The immunohistochemical localization of the enzyme in the nucleus, as well as in the cytosol and plastids, indicates that lily PGAM-i might have multiple functions in the cell.

    Kinetics of pentachlorophenol degradation by a Flavobacterium species (1995)
    Springer

    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract The kinetics of pentachlorophenol (PCP) degradation by a Flavobacterium sp. ATCC 39723 has been investigated. Sodium glutamate was supplied as an additional carbon source to increase the rate of cell growth and PCP degradation. A kinetic model including PCP toxicity for cell growth and PCP inhibition of its own degradation was developed. This model was also applied to 2,4-dichlorophenol (DCP) degradation by the same organism. Although PCP and DCP are degraded by different pathways, the model describes these two degradation processes very well.
