    The interaction between H and CO coadsorbed on Ni{110} (1992)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 97 (1992), S. 8789-8797

    Notes: CO adsorption on Ni{110} and on hydrogen precovered Ni{110} surfaces at 180 K has been studied by FT-RAIRS. On a clean Ni{110} surface CO adsorbs at on-top sites upto a coverage of 0.7 ML. At higher coverages the on-top CO band at 2060 cm−1 decreases in intensity with a concomitant increase in a band at 1960 cm−1 which shifts up in frequency. The (2×1)p2mg structure at 1.0 ML CO coverage shows a single band at 1998 cm−1 attributed to CO tilted at bridged sites. FT-RAIRS of CO adsorption on H precovered Ni{110} surfaces shows complex CO site switching within different CO and H coverage regimes. A model is presented involving compression of H into islands of high coverage and both mixed H and CO and unmixed CO islands are formed. CO adsorbs in the unmixed CO islands the same as that on clean Ni{110}. Within the mixed H/CO islands the first layer nickel atoms reconstruct and a new hydrogen desorption state is observed. The CO site switching observed by FT-RAIRS within the various H and CO coverage regimes is discussed in terms of a dominant indirect interaction.

    UNCONVENTIONAL NANOFABRICATION (2004)
    Palo Alto, Calif. : Annual Reviews
    Annual Review of Materials Research 34 (2004), S. 339-372 
    Details
    ISSN: 1531-7331
    Source: Annual Reviews Electronic Back Volume Collection 1932-2001ff
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Nanostructures are fabricated using either conventional or unconventional tools-that is, by techniques that are highly developed and widely used or by techniques that are relatively new and still being developed. This chapter reviews techniques of unconventional nanofabrication, and focuses on experimentally simple and inexpensive approaches to pattern features with dimensions 〈100 nm. The techniques discussed include soft lithography, scanning probe lithography, and edge lithography. The chapter includes recent advances in fabricating nanostructures using each set of techniques, together with demonstrated advantages, limitations, and applications for each.

    Fabrication of palladium-based microelectronic devices by microcontact printing (2002)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 80 (2002), S. 2222-2224 
    Details
    ISSN: 1077-3118

    Topics: Physics
    Notes: This letter demonstrates the patterning of thin films of metallic palladium by microcontact printing (μCP) of octadecanethiol, and the use of the patterned films in the fabrication of a functional sensor. This technique was also used to prepare templates of palladium for the electroless deposition of copper. The resistivity of the palladium and copper microstructures was 13.8 and 2.8 μΩ cm, respectively; these values are approximately 40% larger than the values for the pure bulk metals. Palladium patterned into serpentine wires using μCP functioned as a hydrogen sensor with sensitivity of 0.03 vol % H2 in N2, and a response time of ∼10 s (at room temperature). © 2002 American Institute of Physics.

    Effect of Antioxidants on Consumer Acceptance of Irradiated Turkey Meat (2003)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 68 (2003), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Antioxidants had no effect on the production of sulfur compounds, color change, and off-odor intensity of irradiated turkey breast meat, but addition of sesamol + tocopherol or gallate + tocopherol was effective in reducing thiobarbituric acid-reactive substance values and aldehydes, especially under aerobic conditions. Consumers preferred the color of irradiated raw and cooked meat to nonirradiated meat because the pink color of irradiated meat looked fresher. The packaging method was more important than the antioxidant treatment in reducing irradiation off-odor because S-compounds produced by irradiation easily volatilized under aerobic packaging conditions. Therefore, the combined use of aerobic packaging and antioxidants is recommended to improve consumer acceptance of irradiated poultry meat.

    Splice loss in single- and twin-core buried channel waveguide devices (1994)
    Springer
    Optical and quantum electronics 26 (1994), S. 45-62 
    Details
    ISSN: 1572-817X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract We quantify the magnitude of the power loss incurred when a square-core buried channel waveguide (BCW) is spliced to a standard circular-core telecommunications fibre. With a view to minimizing the dissipated power, we show that a simple equal-core-area criterion provides an elegant means of determining the optimum core dimensions. This result is found to hold for more general BCW cross-sections that possess a reasonable degree of symmetry. The fundamental problems of waveguide misalignment and angular tilt are also investigated and their effect on splice loss is quantified. Our theoretical model is applied to both single- and twin-core waveguides.

    Efficient coupling of a laser to a waveguide using a taper designed by conformal mapping (2000)
    Springer
    Optical and quantum electronics 32 (2000), S. 197-208 
    Details
    ISSN: 1572-817X
    Keywords: lasers ; pigtailing ; waveguides

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract Maximising the optical power collected in a waveguide from the diffracting field of a semiconductor laser is desirable in optical fibre communication systems. However, the spot size and phase front curvature of the laser field usually makes a poor overlap with the mode of the receiving waveguide. Various proposals have been made to improve this coupling. This paper presents the design of a tapered waveguide section, having the correct geometry and refractive index profile, to efficiently capture and transform the rapidly diffracting light from a semiconductor laser to a planar wavefront in a straight waveguide. Experimentally, such an approach requires the refining of available techniques (UV exposure, ion implantation or diffusion) to obtain the required grading of the refractive index profile within the tapered input section of the receiving waveguide.
