    Notes: [Auszug] IN view of the recent correspondence in NATURE1 bearing on the question of reproductive periodicity in organisms, I should like to direct attention to some observations made by Miss S. M. Marshall and myself in Australia in 1928–29, which appear to indicate a type of such ...

    Notes: [Auszug] I AM preparing a monograph on British Actiniaria which the Council of the Ray Society has undertaken to publish shortly. Certain little-known species of vague systematic position have never reappeared since their first discovery, this usually dating prior to 1860. In such a case it is very ...

    Formation of silicides by rapid thermal annealing over polycrystalline silicon (1986)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 60 (1986), S. 631-634 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: We have investigated the formation of titanium silicide by rapid thermal annealing in nitrogen and argon ambients over polycrystalline silicon. A sheet resistance of about 3 Ω per square for a 300-A(ring) Ti layer was achieved after 900 °C/10-s annealing treatment, which decreased to about 2 Ω per square after 1100 °C/10-s treatment. The silicides were found to be stable during rapid thermal annealing up to 1100 °C/10 s with no or negligible migration of titanium along the grain boundaries in polycrystalline silicon. An external layer (titanium rich, mixture of titanium oxide and nitride) was observed to form during rapid thermal annealing treatment in the nitrogen ambient, but the surface remained clean in the argon ambient.

    Notes: [Auszug] SINCE 1932, an ecological survey of the South ^ African coast has been in progress, carried out from the Departments of Botany and Zoology of the University of Cape Town. The survey is necessarily expensive, since it extends from Durban in the east to Port Nolloth in the west, covering a coastline ...

    Notes: [Auszug] THE letter published in Nature of July 29 from Prof. F. E. Fritsch opens an important subject which has been in the minds of a number of zoologists during the past few years, and it is one in connexion with which some of us would be extremely glad to see action taken on the lines which Prof. ...
