    Development of a compact FE-SEM and X-ray microscope with a carbon nanotube electron source (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-01-26
    Description: A carbon nanotube (CNT) possesses various benefits as a field electron emitter. Multi-walled CNT (MWNT) have exhibited high brightness and the field emission (FE) current is stable even under poor high-vacuum condition of 10 −6 – 10 −7 Pa without ion pumping. In this study, we have experimentally manufactured a compact composite field emission scanning electron microscope (FE-SEM) and X-ray microscope (XRM) with a single isolated MWNT electron source. An electron beam from a MWNT was focussed and accelerated by a Butler electrostatic lens. Stable SEM images were observed at a Butler voltage V but = 1.5 kV and accelerating voltage V acc ≃ 15 kV with a focussed probe current I foc = 61 pA. The spatial resolution of the SEM, which was estimated from 80 – 20 % edge profile of polystyrene latex spheres, was about 9 nm. XRM images were acquired by 30-min exposure at V but = 1.5 kV and V ...

    Film growth mechanism of photo-chemical vapor deposition (1988)

    Notes: Abstract The photo-chemical vapor deposition (CVD) of SiO2 and SiN x were investigated using 185 nm light of a low pressure mercury lamp. The film thickness deposited on the substrate was the function of the distance from the substrate to the light source and its relation was investigated by changing the reaction pressure. From these investigations, the space migration length of the active species was estimated, which was, at the processing pressure of 400 Pa, 10–20 mm. This migration length was confirmed by a model calculation. The step coverage of the film was investigated by the use of a two-dimensional capillary cavity. It was shown that the thickness decayed exponentially with the depth in the cavity. The decay constant did not show temperature dependence. From this result, the surface migration of the active species produced by photo-CVD was reported. To confirm this migration we presented a substrate-size effect of photo-CVD, which became obvious when the substrate size became smaller than the space migration length of the active species. From these results, the film growth mechanism of photo-CVD was discussed.

    Notes: Summary The enzymic activity of Mg2+-or Ca2+-stimulated ATPase fromEscherichia coli was inhibited by one of the troponin components, TN-I, and by mitochondrial ATPase inhibitor (F1-inhibitor). The inhibitory ability of component TN-I against Mg2+-stimulated ATPase activity was lost after digestion of component TN-I with trypsin. The Mg2+-stimulated ATPase activity inhibited by component TN-I was completely restored by the addition of another troponin component, TN-C.

    Effect of season on peripheral resistance to localised cold stress (1984)
    Springer
    International journal of biometeorology 28 (1984), S. 39-45 
    Details
    ISSN: 1432-1254

    Topics: Geography , Physics
    Notes: Abstract This study was carried out to determine the effect that seasonal changes have on the effect of localised cold stress on peripheral temperatures using the foot immersion method with a cold water bath. The subjects were six males and four females. The data were obtained in April, July, October and January. Skin temperature of the right index finger, the forehead, the arm, the cheek, the second toe and the instep were measured before, during and after the immersion of the feet in water at 15°C for 10 mins, as well as oxygen consumption before immersion of the feet. The average finger temperature was highest during foot immersion in the summer, next highest in the winter, then spring, and the lowest during foot immersion in the autumn. The finger temperatures during the pre-immersion period in the autumn tended to be lower than in other seasons. The finger temperatures during the pre-immersion period affected the temperature change of the finger during the immersion period. The rate of increase of the toe temperature and the foot temperature during post-immersion in the summer and the spring were greater than those in the autumn and winter. Oxygen consumption during the pre-immersion period in the autumn was significantly lower than in the other seasons (p〈0.001 or 0.010). Cooling the feet caused no significant changes in the temperatures the cheek, forehead or forearm. The cheek temperature in the summer and autumn was cooler than corresponding temperatures taken in the winter and spring.

    Preparation of a transparent alumina film doped with CdS and its nonlinear optical properties (1992)

    Notes: Abstract We have examined the preparation of transparent alumina film and CdS-doped alumina film prepared by the sol-gel process using aqueous sol starting from AlCl3. The resulting alumina films obtained by sol-gel transformation are transparent in the visible and near infrared up to 1000 °C. Homogeneous solution of alumina sol and Cd(CH3COO)2 was converted into gel film by dehydration. Then, on exposure to H2S stream at 250–600 °C, a CdS-doped film was obtained. It shows relatively sharp blue-shifted visible absorption that is attributed to size quantization effect. Large nonlinear absorption and refractive index have been obtained, because high concentration of CdS particles can be achieved by using this method.

    Sol-Gel Preparation of Silica Films with Controlled Surface Morphology and Their Application to a Low Reflective Glass (1999)
    Springer
    Journal of sol gel science and technology 14 (1999), S. 175-186

    Topics: Chemistry and Pharmacology
    Notes: Abstract Silica coating films with various surface morphologies, such as flat, porous (with deep pores), concave-convex (with hills and valleys), and convex (with hills on flat plane) structure were prepared from a mixture of two kinds of sols derived from polymerized tetraethoxy-silane (TEOS) and methyltriethoxysilane (MTES). Different surface morphologies were obtained by varying the molar ratio r = MTES/TEOS of the coating solution. The surface was flat for r less than 2.5, porous for 2.5 ≤ r 〈 5, concave-convex for 5 ≤ r 〈 7.5, convex for 7.5 ≤ r 〈 13, and again flat for r larger than 13. For 2.5 ≤ r 〈 5, the apparent refractive index of the silica film with porous morphology was decreased to 1.23 by selecting the solvent and by controlling the relative humidity of the coating atmosphere and the heat treatment temperature. Coating of glass with silica films of low refractive index of 1.23 led to the low reflective glasses with visible light reflectance Rvis of less than 0.2%.

    Notes: Summary The effects of the addition of sulfurous acid into culture solution and of cold treatment of the solution were examined to simplify the culture of detached wheat ears. In the simplified method, detached ears could be cultured at room temperature on the liquid medium containing 100 g/l sucrose and 0.075% sulfurous acid without any sterilization. The immature seeds in detached ears cultured by this method were treated with low temperature or with chemicals known to have vernalizing effect. The chemical treatment did not affect the chilling requirement of immature embryos, although photoperiodic response and narrow-sense earliness were reduced by kinetin and trypsin. The low temperature treatment drastically affected the chilling requirement, and fully vernalized mature seeds having normal germinability were obtained by treating the detached ears in culture with low temperature from 10 days after anthesis.

    Dynamic Motion of Superfluid Bubble in Solid 4He (1998)
    Springer
    Journal of low temperature physics 113 (1998), S. 775-780 
    Details

    Topics: Physics
    Notes: Abstract We have observed an interesting motion of a superfluid bubble in solid 4 He with the solid/liquid interface through the video camera. The host hcp crystal was formed at around 0.8 K with c-axis oriented approximately 45 degrees from the horizontal solid/liquid interface. When a fairly strong power of 10 MHz pulsed sound was applied to a transducer in the solid, a small rounded liquid droplet was nucleated at one spot on the transducer. The droplet became larger as the sound pulse continued to be applied, developing over the entire transducer, and finally began to grow upwards. As it increased in size, the c-facet was observed in the bubble. At this time the shape of the bubble became something like a pyramid. When a top of the pyramidal shape of the bubble touched the interface, it changed its shape drastically, rapidly merged into the superfluid phase. The detailed motion was determined by careful observation of the video records. When the bubble size became pretty large, the horizontal interface moved upward to compensate the lower density of the bubble in order that total number of atoms in the cell should be retained.
