    Notes: Fibrinogen and albumin are two of the most important plasma proteins that relate toblood coagulation caused by engineered surfaces. In this paper, the adsorption behavior of albuminand fibrinogen on single-walled carbon nanotubes nonwoven (SWNT nonwoven) was investigatedthrough scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), near edgeX-ray adsorption fine structure spectroscopy (NEXAFS) and direct enzyme-linked immunosorbentassay (ELISA) respectively. It was concluded that SWNT nonwoven displayed strong adsorptionpreference of fibrinogen to albumin. In addition, the immune activity of fibrinogen adhered to theSWNT nonwoven surface was found remained and showed a linear response to the concentration ina certain range

    Suppression of silicide formation in Fe films grown on Si(001) (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 88 (2000), S. 5289-5292

    Notes: Thin ferromagnetic Fe films were grown at both room and low temperatures (150 K) on (2×1) and on Au-passivated Si(001). In the case of Fe grown on (2×1) Si(001), the magnetization sets in at an Fe coverage of 3.6 monolayers (ML) at room temperature and of 2.3 ML at 150 K, indicating a reduced magnetization due to silicide formation. To suppress Fe–Si reactions we used a 2 ML thick Au buffer layer deposited in two steps. We performed a reconstruction by the deposition of about 0.5 ML of Au at ∼1000 K followed by the growth of another 1.5 ML at room temperature or at 150 K. Room temperature growth results in rough Au films and no earlier onset of magnetization in comparison to the case of unbuffered Fe films. However, a strong out-of-plane magnetization is measured at the onset coverage. By contrast, at 150 K, smooth Au buffer films are observed, acting as protective layers against Fe and Si intermixing. Growth on these buffer layers results in an early onset of the out-of-plane magnetization at 1.4 ML of Fe and a larger Kerr signal. Both these findings point at a significant reduction of silicide formation. A 2.3 ML thick Fe film grown on Au passivated Si(001) shows a reversible magnetic behavior upon annealing to 280 K and cooling back to 150 K, indicating a thermally stable system. © 2000 American Institute of Physics.

    Notes: With the carbon nanotube nets being chosen as a substrate, the nanoscale nickel balls have been fabricated by using electroless plating method. In this article, a sample with well dispersed nanoscale nickel balls was prepared by ultrasonically dispersing them in PVK polymer solution and spraying them on a new cleavage of mica. Their images of topography and micromagnetic structure were obtained by transmission electron microscopy, and magnetic force microscopy with the magnetic tips coated with cobalt film. The balls with the diameter ranging from 200 to 400 nm present the same type of magnetic force image pattern, indicating that they are all single crystals with a single domain. Computer simulation was carried out by integrating the interactions between the tip and the balls. The simulated images are consistent with the real patterns. © 1999 American Institute of Physics.

    La–Zn substituted hexagonal Sr ferrite thin films for high density magnetic recording (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 87 (2000), S. 2503-2506 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: La–Zn substituted M type Sr-ferrite thin films were prepared by conventional rf diode sputtering. The crystallography, surface morphology, magnetic properties, and their temperature dependence were investigated by x-ray diffractometry, atomic force microscopy, and vibrating sample magnetometry. La–Zn substitution reduces the grain growth rate, so that it was possible to obtain fine grains with mean grain size about 12 nm×12 nm. Suitable amount of La–Zn substitution increases the saturation magnetization Ms of the films without changing the magnetocrystalline anisotropy of the material. As a result, the coercivity Hc increases with the increase of the La–Zn substitution. La–Zn substitution also reduces the values of dHc/dT of the films in the vicinity of room temperature. © 2000 American Institute of Physics.

    Notes: Nd:Gd2O3-HfO2 powder has been prepared with a co-precipitation method. The size ofNd:Gd2O3-HfO2 powder is near 50nm. Transparent Nd:Gd2O3-HfO2 ceramics were successfully fabricatedby sintering the powder compact at 1800°C under H2 atmosphere. The synthesis process and opticalproperties were investigated in detail. By measuring the optical properties of transparent Nd:Gd2O3-HfO2ceramics, we found that the absorption bond of Nd ions near 808nm is enlarged, and the FWHM of theemission bond near 1060nm is near 25nm. It was believed that Nd:Gd2O3-HfO2 transparent ceramic ispotential laser material for the usage in solid-state heat-capacity laser(SSHCL) application

    Notes: Summary Ion conducting polyurethane electrolyte with redox active ferrocene groups which are fixed to the polymer backbone by covalent bonds was prepared. It has been found that the resulting polyurethane electrolyte has high conductivity even at lower temperature. And the temperature dependence of conductivity follows well the Arrhenius equation. Solid state electrochemical property was measured by cyclic voltammetric method with microdisk electrodes at different temperature. The results indicated that the polyurethane electrolyte has good redox stability, as well as reiteration, and show electrochemical activity in the solid state.

    Improvement of para-selectivity in methylation of toluene on various MFI-type metallosilicate catalysts (1996)
    Springer

    Notes: Abstract MFI-type metallosilicates incorporating various transition metal elements were synthesized by the rapid crystallization method. Compared with H-ZSM-5, these metallosilicates possess fewer acid sites and weaker acidic strength. In the methylation of toluene with methanol, protonated metallosilicates exhibited lower conversion of toluene, higher para-selectivity and higher yield of paraxylene than H-ZSM-5. Distributions of trimethylbenzene and tetramethylbenzene isomers produced in toluene methylation indicate that the effective pore size (openings and/or channels) of metallosilicates may be smaller than that of ZSM-5, which is more advantageous for formation of the smallest isomers in trimethylbenzenes and tetramethylbenzenes. The relation between the paraselectivity in toluene methylation and the isomerization activity in para-xylene conversion suggests that the para-selectivity could occur exclusively, when isomerization of para-xylene to other isomers could be completely prevented. Therefore, the improvement in para-selectivity on MFI-type metallosilicates should be attributed to both the reduction in effective pore size and the decrease of strong acid sites, on which produced para-xylene would be isomerized to ortho- and meta-xylenes.
