    Notes: High-quality single-crystal molybdenum (Mo) fabricated by a secondary recrystallization method has been polished with a new polishing technique. The superpolished surface of the Mo single crystal has a surface roughness of 3.5 A(ring) rms. This superpolished single-crystal Mo has been used for a high-power electron beam pumped argon excimer laser (λ=126 nm) as a cavity mirror. Peak output power of more than 3 MW has been achieved without any damage to the mirror surface.

    Aluminum selective area deposition on Si using diethylaluminumchloride (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 55 (1989), S. 741-743

    Notes: Aluminum deposition on Si was studied using diethylaluminumchloride (DEAlCl) as a new Al chemical vapor deposition source. Selective area deposition was successfully achieved at substrate temperatures of 313–380 °C. The deposition rate was higher than 370 A(ring)/min. Reflectance and resistivity of the deposited films were comparable to those of the evaporated ones. Decomposition experiments suggest that DEAlCl catalytically decomposes on the Al surface, which would explain the high selectivity observed.

    Notes: Summary A new potent antiauxin, α-(5,7-dichloroindole-3-)isobutyric acid has been synthesized and shown to inhibit auxin-mediated elongation ofAvena coleoptiles and to stimulate root growth of rice seedlings. Its activity is stronger than α-(p-chlorophenoxy)isobutyric acid and is comparable to that of 2,3,5-triiodobenzoic acid, which are typical antiauxins.

    The applications of the stark effect to the stabilization of the CO2 laser and the submillimeter laser (1987)

    Keywords: optically pumped submm laser ; stabilization ; Stark effect

    Topics: Physics
    Notes: Abstract Methods based on the Stark effect are described for dither-free frequency stabilization of the optically pumped submm laser. The CO2 pump laser was stabilized using a Stark Lamb dip signal of the submm lasant in an external Stark cell. An estimated frequency stability (Δf/f) better than ±1.4×10−8, for one hour recording, was obtained by this method. The frequency of the submm laser was stabilized using the d.c. and a.c. Stark effects for a metal-dielectric rectangular waveguide laser. An estimated frequency stability of ±6×10−8 was obtained for 119 μm line of CH3OH laser for one hour recording.

    Measurement of thermophysical properties of molten salts: Mixtures of alkaline carbonate salts (1988)
    Springer
    International journal of thermophysics 9 (1988), S. 1071-1080 
    Details
    ISSN: 1572-9567
    Keywords: alkaline carbonate salts ; density ; high temperatures ; molten salts ; specific heat capacity ; stepwise heating method ; thermal conductivity ; thermal diffusivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The purpose of this study is to develop measuring methods for the thermal diffusivity, the specific heat capacity, and the density of molten salts, as well as to measure these properties of mixtures of alkaline carbonate salts. The thermal diffusivity is measured by the stepwise heating method. The sample salt is poured into a thin container, and as a result, a three-layered cell is formed. The thermal diffusivity is obtained from the ratio of temperature rises at different times measured at the rear surface of the cell when the front surface is heated by the stepwise energy from an iodine lamp. The specific heat capacity is measured using an adiabatic scanning calorimeter. The density is measured by Archimedes' principle. Thermal conductivity is determined from the above properties. Measured samples are Li2CO3-K2CO3 (42.7–57.3, 50.0-50.0, and 62.0-38.0 mol%).

    Electrofusion for the pronuclear transplantation of mouse eggs (1987)
    New York, NY : Wiley-Blackwell
    Gamete Research 17 (1987), S. 15-20 
    Details
    ISSN: 0148-7280
    Keywords: nuclear transplantation ; electrofusion ; Life and Medical Sciences ; Cell & Developmental Biology
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology
    Notes: The present study was undertaken to determine the efficiency of HVJ treatment and electrofusion for pronuclear transplantation in the mouse. The output voltage and duration of the pulses were fixed to 200 μsec at 10 V or to 150 μsec at 15 V for electrofusion, because the maximum rates of blastomere fusion of 2-cell embryos and development of fused embryos in vitro were obtained under these conditions. Although the proportion of eggs with fused karyoplast (78%) and the fused eggs developed to morulae or blastocysts (67%) was significantly lower than those obtained after HVJ treatment (94% and 94%), the proportion of pregnant recipients and young obtained after treatment of fused eggs was not significantly different between these two procedures.It is advised that electrofusion can be used as a fusogenic procedure for pronuclear transplantation in the mouse in some cases where HVJ cannot be applied.

    Application of high-performance liquid chromatography/atmospheric pressure ionization mass spectrometry for the analysis of non-volatile compounds (1988)

    Notes: The combination of a high-performance liquid chromatograph and a magnetic type mass spectrometer with an atmospheric ionization source has been applied for analyses of thermolabile compounds, i.e. antibiotics, amino acids and glycosphingolipids.Chromatography was performed on a 4 mm i.d. x 150 mm column packed with 5 μm ODS at a flow rate of 1 ml min-1. The liquid chromatography/atmospheric pressure ionization (LC/API) magnetic-type mass spectrometer provides not only an abundant pseudo-molecular ion but also fragment ions which give a structural information resulting from collision-induced dissociation at the differential pumping region of the liquid chromatograph/mass spectrometer interface. The isomers of kanamycins could be differentiated from each other on the basis of their mass spectra obtained at the relatively higher drift voltage applied. LC/API mass spectra of leucine and isoleucine were very similar, but it was easy to differentiate one from another by checking the existence of the ions at m/z 43 or m/z 57 in their mass spectra. The LC/API mass spectra of glucosylceramides showed [MH]+ ions of good abundance and significant fragment ions useful for chemical characterization at a proper drift voltage setting in a controlled and reproducible manner.
