    Notes: Seebeck, electrical, and thermal conductivity data are reported on CoSb3, and doped and undoped alloys of Co1−xIrxSb3−yAsy from 20 to 700 K. n-type semiconductors were obtained by doping with Ni, Te, or Pd, and the hole concentration in p-type samples was increased by substitution of Fe, Ru, Os, and Ge. An estimated maximum value for ZT of 0.6 (Z is the figure of merit) was found for a Te-doped (n-type) alloy at 700 K. For p-type alloys, the maximum value of ZT was found to be 0.3 at 550 K. Electrical and thermal transport data also are reported for CoAs3, RhSb3, and IrSb3. Most of the samples investigated were polycrystalline, but a few measurements on CoSb3 single crystals also are discussed. © 1995 American Institute of Physics.

    An automated system for current–voltage characterization of ceramic superconductors (1996)

    Notes: An automated system for determinations of transport current–voltage (I–V) characteristics as a function of temperature (25–125 K), magnetic field (0–1.6 T), and magnetic field orientation (−125 to +145°) is described. Currents of up to 100 A are applied either as a continuous ramp or as pulses of 2–100 ms duration. A closed-cycle helium refrigerator provides a rapid (∼45 min), convenient, cost effective, cooldown from 300 to 25 K. Control of current, temperature, magnetic field, and field orientation is fully automated and requires no user interaction. The characterization of performance of a ceramic superconductor typically involves several temperatures, fields, and orientations and requires 8–30 h to complete. © 1996 American Institute of Physics.

    High critical current density superconducting tapes by epitaxial deposition of YBa2Cu3Ox thick films on biaxially textured metals (1996)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: A method to obtain long lengths of flexible, biaxially oriented substrates with smooth, chemically compatible surfaces for epitaxial growth of high-temperature superconductors is reported. The technique uses well established, industrially scalable, thermomechanical processes to impart a strong biaxial texture to a base metal. This is followed by vapor deposition of epitaxial buffer layers (metal and/or ceramic) to yield chemically compatible surfaces. Epitaxial YBa2Cu3Ox films grown on such substrates have critical current densities exceeding 105 A/cm2 at 77 K in zero field and have field dependencies similar to epitaxial films on single crystal ceramic substrates. Deposited conductors made using this technique offer a potential route for the fabrication of long lengths of high-Jc wire capable of carrying high currents in high magnetic fields and at elevated temperatures. © 1996 American Institute of Physics.

    Widespread occurrence of mycosporine-like amino acid compounds in scleractinians from French Polynesia (1997)

    Notes: Abstract.  A survey of 23 species of scleractinians, belonging to seven families and 8 genera, collected from two different areas in French Polynesia, showed that all specimens possessed between four and seven UV-absorbing compounds, identified as mycosporine-like amino acids (MAAs). In all, 11 different MAAs molecules were found, of which two were previously unknown. Palythine and mycosporine-glycine were the most abundant MAAs in the corals. With few exceptions, most specimens of each species possessed the same pattern of MAAs. Similarly, species from the same genus also had very similar qualitative composition of MAAs, although quantities of individuals MAAs varied from specimen to specimen. This suggests that MAAs are ancient and evolutionarily well conserved.

    High Critical Current Density YBa2Cu3O x Tapes Using the RABiTs Approach (1998)

    Notes: Abstract Progress in the fabrication of epitaxial, high-J c, biaxially aligned YBCO thick films on Rolling-assisted biaxially textured substrates (RABiTs) is reported. RABiT substrates comprise a biaxially textured metal substrate with epitaxial oxide buffer layers suitable for growth of superconductors. Oxide buffer layers have been deposited using three techniques: laser ablation, electron-beam evaporation, and sputtering. Epitaxial YBCO films grown using laser ablation on such substrates have critical current densities approaching 3 × 106 A/cm2 at 77 K in zero field and have field dependences similar to epitaxial films on single crystal ceramic substrates. Critical current densities in excess of 0.2 MA/cm2 have been obtained on stronger, nonmagnetic substrates. In addition, samples with J e of 12.5 kA/cm2 at 77 K have been fabricated. The highest strain tolerence obtained so far is 0.7% in compression and 0.25% in tension. Deposited conductors made using this technique offer a potential route for the fabrication of long lengths of high-J c wire capable of carrying high currents in high magnetic fields and at elevated temperatures.

    In situ and Real-Time Monitoring of Plasma-Induced Etching of PET and Acrylic Films (1999)

    Notes: Abstract Residual gas analysis (RGA) and optical emission spectroscopy have been evaluated as potential in situ techniques for the detection of plasma-induced polymer surface etching. The detection is based on the measurement of CO and CO2 species formed in the gas phase following oxidation of the etching fragments released from the polymer surface. Experiments were performed on poly(ethylene terephthalate) and UV-cured acrylic (tripropylene glycol diacrylate) films exposed to O2 RF (13.56 MHz) plasmas. A linear correlation is obtained between the formation of CO and the polymer etching rate over the entire experimental range, but discrepancies appear for the formation of CO2 at high treatment powers (etching rate 〉 1.0 μg/min.cm2). This behavior is attributed to a deficit of oxidizing agents relative to the generation of etching fragments. The results suggest that both RGA and optical emission spectroscopy can be used to monitor in situ and in real-time the etching of polymer surfaces during plasma treatment.
