    Notes: This article reports on a technique for patterning diamond nanogrit which utilizes commercial ink-jet printer technology. Diamond nanogrit as small as 50 nm has been successfully printed onto substrates of glass, silicon, copper, and fused quartz. The technique has been used to demonstrate a quick and simple means to seed patterned. nanocrystalline diamond films onto candidate substrates of potentially any conceivable size or shape. © 2000 American Institute of Physics.

    Field emission properties of diode devices based on amorphic diamond-Si heterojunctions (1997)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 81 (1997), S. 1505-1508

    Notes: Microscopic and macroscopic field emission properties of amorphic diamond films on n- and p-type silicon substrates were studied by combined scanning tunneling microscopy/spectroscopy and integral field emission I–V measurements. Microscopic scanning tunneling spectroscopy showed that amorphic diamond films on n-Si have lower threshold voltage and higher emission current than amorphic diamond films on p-Si. The observed rectification characteristics suggest that amorphic diamond on n-Si is an ideal forward-biased p-n junction cold cathode emitter; however, there is no significant difference between these two structures by integral field emission I–V measurements. Conversion of the smooth amorphic diamond film into porous sp3/sp2 composites with sharp features under electric fields higher than 50 V/μm, followed by preferred electron emission from the porous composite sites of high transconductance, was believed to be the cause. © 1997 American Institute of Physics.

    Negative electron affinity observed in boron-doped p-type diamond films by scanning field emission spectroscopy (1996)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 80 (1996), S. 6809-6812

    Notes: Field emission properties of boron-doped diamond films were studied by combined scanning tunneling microscopy/spectroscopy and scanning field emission spectroscopy. A detailed spatial correlation between field emission sites and diamond morphology, surface work function, and diamond quality can be established by this technique. A possible indication of negative electron affinity of the (111) faces near the (111)/(111) and (111)/(100) grain boundaries and high defect sites of boron doped p-type diamond films were observed by field emission I–V (current–voltage) measurement. © 1996 American Institute of Physics.

    Field emission properties of diamond films of different qualities (1997)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 71 (1997), S. 2337-2339

    ISSN: 1077-3118

    Topics: Physics
    Notes: Field emission properties of diamond films were studied by macroscopic I–V measurement. A lower turn-on field and a higher emission current were observed for diamond films produced by higher methane concentration, or with higher density of defects, introduced by ion implantation. However, diamond films of poorer quality experience a severe reliability problem. Cold implantation followed by rapid thermal or laser annealing produced diamond emitters with a turn-on field as low as 5 V/μm and the desired reliability. © 1997 American Institute of Physics.

    Growth and field emission properties of multiply twinned diamond films with quintuplet wedges (1996)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 69 (1996), S. 2825-2827

    ISSN: 1077-3118

    Topics: Physics
    Notes: A unique microwave plasma chemical vapor deposition (MPCVD) technique was employed to produce multiply twinned diamond films with quintuplet wedges. Biased nucleation, nonbiased growth, and high methane/hydrogen ratio ((approximately-greater-than)5%) were used to prepare the multiply twinned diamond films. The growth parameter α was carefully controlled to be close but larger than 3/2 to allow the multiply twinned particles with quintuplets to outgrow the parent face to form the secondary crystals with uniformly distributed particle sizes and smooth surface. Since there is no need to suppress the natural growth of twins in vapor-grown diamond, higher growth rate was achieved. Excellent field emission properties of such films compared to the normal MPCVD diamond films were also obtained. © 1996 American Institute of Physics.

    Compression testing of granular NPK fertilizers (1997)

    Nutrient cycling in agroecosystems 48 (1997), S. 231-234

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract The crush strength of granular NPK fertilizer has been accurately determined using Instron compression testing equipment. Stress-strain analysis shows a distinctive break point followed by break up of granule fragments. The force required to crush the granules is a function of the granule diameter but the calculated pressure required to crush each granule remained relatively constant. Factors such as moisture ingress and coating oils have been shown to affect granule strength. A direct link between caking of granular fertilizers and crush strength has been established.

    Description / Table of Contents: Zusammenfassung Es werden einige Einschränkungen für die Randbedingungen in der Kontinuumsmechanik behandelt, die von der Forderung herrühren, dass für die Materie ausserhalb der Grenzfläche die fundamentalen Bilanzgleichungen, die Invarianzbedingungen und die Entropieungleichung gelten sollen. Diese Behauptungen werden für polare Materialien erläutert, jedoch sind die hier eingeführten Begriffe auf Kontinuumstheorien aller Art anwendbar.
    Notes: Summary We discuss some restrictions on boundary conditions in continuum mechanics arising from the requirement that the basic balance laws, invariance conditions and entropy inequality must hold for the material outside of the bounding surface. We illustrate our assertions for polar materials, but the ideas we use are applicable to all continuum theories.
