    Novel characterization of implant damage in SiO2 by nuclear-deposited energy (1989)

    Notes: Etching enhancement in through-implanted SiO2 has been characterized by nuclear-deposited energy independently of implant conditions. An empirical expression has been proposed to describe the etching rate for any implantation. The enhanced etching has been related to the Si-O vibrational frequency shift. Etching enhancement has been found to reflect the structural change in SiO2, and to be a good measure of degradation. The structural change of SiO2 stops and the etching rate reaches a maximum for an ion dose corresponding to nuclear-deposited energy larger than 3.4×1023 eV/cm3. This energy is equal to the total SiO bonding energy (3.8 eV) in a unit volume of SiO2.

    In situ observation by ultrahigh vacuum reflection electron microscopy of terrace formation processes on (100) silicon surfaces during annealing (1989)

    Notes: Formation processes of terraces on (100) silicon surfaces during annealing at 1000 °C were observed in situ by ultrahigh vacuum reflection electron microscopy. Terraces were formed on staircases made up of monoatomic steps, preferentially at the sites where stairs were larger than average. The sites are formed by surface undulation. It was found that the terrace grew, or extended, in both up-step and down-step directions almost at equal rates. The terrace thus grew not by sublimation, but by adhesion and removal of atoms at respective terrace edges. Thus, the interlayer migration of adatoms plays an important role in the terrace growth.

    Notes: Abstract— —An enzyme catalysing the transfer of sulphate from 3′-phosphoadenylsulphate to serotonin was purified from rabbit brain. The purification procedure involved ammonium sulphate fractionation of the 200,000 g supernatant of rabbit brain homogenate, treatment with alumina Cγ, and chromatography on DEAE-cellulose. The enzyme was purified 67-fold from the 200,000 g supernatant of the brain homogenate. The intracranial distribution of the sulphotransferase was investigated and the cerebellum found to have rather high activity. The sulphotransferase activities of rabbit, dog, rat and bovine brains were compared; rabbit brain had the highest activity, followed by dog, rat and bovine brain.

    LIFE PREDICTION OF 316 STAINLESS STEEL UNDER CREEP-FATIGUE LOADING (1987)

    Notes: Life prediction for creep-fatigue loading conditions should be related to creep damage mechanisms. In order to examine the effect of the creep damage mode on rupture life under creep-fatigue loading, a “combined creep-fatigue loading test” was carried out on 316 stainless steel. In this method, creep loading and fatigue loading are repeated alternately. The fracture criteria under combined loading closely depend on the creep fracture modes of the static creep test. A new life prediction method which uses this new fracture criterion is proposed. The criteria are changed when the creep damage mode varies. In order to verify the adequacy of this method, fatigue tests with a tensile strain-hold wave form were carried out. It is clear that rupture life in such fatigue tests is dependent on the chosen fracture criteria.

    Notes: Reflection electron microscopy (REM) in ultra-high vacuum (UHV) conditions is reviewed. UHV-REM can characterize surface structures of monolayer levels such as steps, domains of reconstructed surface structures and their boundaries and these capabilities are used to observe surface dynamic processes such as phase transitions of reconstructed surface structures and adsorbate structures and adsorption processes, oxidations, sublimations and ion-sputtering and annealing. The method is compared with other surface-imaging techniques.

    Notes: Ordered and disordered states of potassium ions in (111) tunnels in the structure of cubic KSbO3 have been studied by high-resolution electron microscopy. N-beam calculations for the images of both the ordered and disordered states reproduce well the observed images. The disordered state changes into the ordered state under electron irradiation during the observations. Electron diffraction from the specimens and optical diffraction from the images show diffuse spots due to small domains of the long-range-ordered state, but no other diffuse scattering due to short-range order has been observed.

    Notes: The crystal structures of phases, previously designated as 11L, 9L and 16L, which were commonly found in the title systems are suggested from their high-resolution two-dimensional electron-microscope images. Two types of blocks are found which are composed of five and six layers of pentavalent-metal oxide octahedra and are closely related to the pyrochlore structure. The 11L structure is of rhombohedral {\tt ABCABC} stacking of the former type of block, and the 9L structure is of hexagonal {\tt B}_{0}{\tt A}_{0}^{\prime}{\tt B}_{0}{\tt A}_{0}^{\prime} stacking of the latter type of block. The 16L structure is found to be an alternate stacking of the two types of blocks. The method of stacking of the blocks is the same for the three structures and is found to be favorable from the point of view of local charge balance.
