    Measurements of thermal creep in binary gas mixtures (1999)

    Notes: Thermal creep occurs in all nonisothermal gas–mixture systems. The effect is more pronounced in rarefied gases and can play a significant role in, for example, microgravity crystal growth experiments, where natural convection is suppressed. Experimental measurements of the thermal creep in gas mixtures are, however, simply not available. We report experimental measurements of thermal creep in three binary gas mixtures: He:Ar, He:CO2, and Ar:CO2 at different mole ratios (mixture fractions). A stainless steel two-bulb measurement system employing seven capillaries to connect the bulbs is used to measure the steady-state pressure differences that develop between the bulbs for each mixture at a selection of total system pressures. Values of the total system pressure that were used range from 0.12 to 10.00 Torr. For all of the data reported, the two bulbs were held at temperatures of 397 and 297 K for the hot and cold sides, respectively. From the measured pressure differences, experimental values are obtained for a newly identified creep factor from which the thermal creep is extracted. These experimental values agree well with those obtained from some recently reported theoretical expressions, provided that suitable values for the accommodation coefficients of the gases are chosen. © 1999 American Institute of Physics.

    Enhancement of electron emission efficiency of Mo tips by diamondlike carbon coatings (1996)

    Notes: The effect of diamondlike carbon (DLC) films coated by pulsed laser deposition technique on the electron emission characteristics of Mo tips is examined. Turn-on voltage (V0) was lowered from 40 V for Mo tips to 22 V for DLC coated Mo tips and maximum anode current (IA) was increased from ∼44 μA for Mo tips to ∼2.0 mA for DLC coated Mo tips. Maximum anode current (IA) for the DLC coated Mo tips, however, decreased during operation. Raman spectroscopy and selected area diffraction (SAD) in transmission electron microscopy (TEM) revealed that the degradation of electron emission behavior can be ascribed to the conversion of sp3-bonds, characteristic for diamond, to sp2-bonds, characteristics for graphite. The transformation of the structure is assumed to be induced by the local heat from the DLC coatings. © 1996 American Institute of Physics.

    Advanced CCD imager technology for use from 1 to 10 000 A(ring) : Eighth topical conference on high−temperature plasma diagnostics (1990)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have developed a low-noise, high-sensitivity charge-coupled-device (CCD) technology for imaging applications extending from the soft x-ray (1 A(ring)) to the near-infrared (10 000 A(ring)) regimes. We have also developed a fabrication technology for making back-illuminated versions of these devices with quantum efficiencies as high as 90% from 5000 to 7000 A(ring). Our efforts have focused on two devices, a 64×64 pixel back-illuminated imager with two output ports that operates at 2000 frames per second with 23 electrons read noise, and a larger device, with 420×420 pixel format, designed for lower frame rates with noise as low as 1.5 electrons and used at visible, UV, and x-ray wavelengths. Applications to plasma diagnostics include Thomson scattering and high-frame-rate imaging in the visible, as well as x-ray imaging and bolometry.

    The morphology and conductivity of polypyrrole/polyurethane alloy films (1992)

    Notes: Abstract Polymeric composites with conductivities ranging from 10−4 to 1 S cm−1 were prepared by electrochemically polymerizing pyrrole in a matrix of polyurethane. The polypyrrole/polyurethane alloy films obtained were characterized by element analysis, electron microscopy and electrical conductivity measurements. The morphology of the films depended on the solvent, the electrolyte and the current density. The mechanism of the electrochemical polymerization showed that PPy grew in a treelike structure, with molecular chains extending from the electrode surface into the solution. The transition temperature of the PPy/PU increased with the PPy content.

    Notes: Abstract  A temperate phage was induced by mitomycin C from Leuconostoc oenos strain 1002, a New Zealand isolate. The phage has an isometric head (52±3 nm) with a tail (210±10 nm) and gives a lytic burst size of 25 when grown on a sensitive strain. Three major structural proteins of 43, 30 and 14 kDa are visible by Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). A restriction map of the 36-kb genome was determined. Commercially available L. oenos strains PSU-1, ML34 and Lco23 and 46.6% of New Zealand isolates were sensitive to the phage.

    Notes: Abstract: Gout with systemic lupus erythematosus (SLE) or progressive systemic sclerosis (PSS) has rarely been reported, whereas mixed connective tissue disease (MCTD) with the demonstration of intra-articular monosodium urate crystals has never been reported. We describe an unusual case of MCTD (SLE–PSS) in a 37-year-old woman who developed acute gouty arthritis. Arthrocentesis and synovianalysis may be necessary to differentiate gout from the arthropathy of MCTD.
