    Quantitative analysis of the retrograde reaction of motoneurons with an image analyser (1990)

    Anatomy and embryology 181 (1990), S. 373-379

    Notes: Summary The neuronal profiles of cell bodies in the facial nerve nucleus of adult rats were measured after partial peripheral nerve transsection. An image analyser was used for automatic recognition and morphometry. Based on classification of the neuronal profiles described in a previous paper, a morphometrical study was performed in order to analyse structural aspects of the retrograde reaction in quantitative terms. Beside the quantification of classical features of retrograde reaction (chromatolysis; nuclear eccentricity; increased basophilia; perikaryal, nuclear and nucleolar swelling), several reactive changes so far not recognized (karyoplasmic basophilia and granulation) were detected. These changes were interpreted as morphological correlates of regeneration in retrogradely reacting cells.

    Determination of hydrogen depth profiles in polymer films by the 15N nuclear reaction technique (1993)
    Springer
    Fresenius' Zeitschrift für analytische Chemie 346 (1993), S. 151-154 
    Details

    Notes: Summary It has been shown that the 15N nuclear reaction technique for hydrogen profiling can be used for the characterization of polymer films. With an optimized sample geometry, a depth resolution of 5 nm near the sample surface is achieved. A special γ-ray detector allows radiation damage in the sample to be minimized. Since the 15N technique discriminates between the hydrogen isotopes H and D, a suitable contrast between the different components of a polymer film is achieved by deuterating one component of the polymer. This has been utilized in the study of the surface-induced lamellar ordering within diblock copolymer films.

    Development of a measuring set-up for high-sensitivity analysis of hydrogen by the 15N nuclear reaction technique (1993)
    Springer
    Fresenius' Zeitschrift für analytische Chemie 346 (1993), S. 205-207 
    Details
    ISSN: 1618-2650

    Topics: Chemistry and Pharmacology
    Notes: Summary A newly developed measuring set-up for analysis of hydrogen in solids at a concentration level of 10 at.ppm is described. Main features are a special λ ray detector and provisions for reduction of different kinds of background. Various factors determining the sensitivity are discussed and the capability of the measuring set-up is illustrated by several examples.

    Correlation of hydrogen content with properties of oxidic thin films (1992)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 19 (1992), S. 435-438

    Notes: Hydrogen and hydrogen-containing species (H2O, OH etc.) play a dominant role in the various properties of glass surfaces and technical oxidic thin films deposited on glass. The amount of hydrogen and its distribution with depth are influenced by preparation and production processes, film materials, density and voids, etc. The 15N nuclear reaction technique, which works quantitatively and non-destructively, was used to investigate glass surfaces and thin films of TiO2, Ta2O5 and SiO2 produced by sol-gel processes, reactive evaporation, sputtering and ion plating on glass substrates. An increase or decrease in hydrogen content influences optical and mechanical properties such as the refractive index and adhesion of the films.

    In-depth profiling of hydrogen in oxidic multilayer systems (1990)
    Chichester [u.a.] : Wiley-Blackwell

    Topics: Physics
    Notes: The hydrogen concentration profiles of electrochromic multilayer systems produced by evaporation have been determined by means of nuclear reaction analysis. The H content of individual oxidic materials was found to be larger than for single films, especially for SiO2. The time-dependent H uptake under various ambient conditions was investigated. Systems produced by ion plating were also profiled for hydrogen.
