    Notes: Isolated diamond particles grown by chemical vapor deposition on a mirror-polished Si substrate have been studied by cross-sectional transmission electron microscopy. Focused ion beam micromachining enabled the cross-sectional specimen to be carved out precisely at the center of the particle. Atomic scale observation of the diamond/Si interface revealed the presence of an ∼3 nm thick amorphous intermediate layer including a few pits around the nucleation site of the particle. Growth mechanism and relationship between growth orientation and internal defect structure of the diamond particle are discussed. © 1995 American Institute of Physics.

    Transmission electron microscopy study of interface and internal defect structures of homoepitaxial diamond (1996)

    Notes: Defect structures in a homoepitaxial diamond film grown by chemical vapor deposition have been studied by cross-sectional transmission electron microscopy. Many interstitial dislocation loops are discerned in the (001) interface. The internal region grown on the (11¯1) facet comprises stacking faults and twins, while that on the (001) face contains mainly interstitial dislocation loops aligned in rows along ∼〈112〉 directions. Fe and Si impurities were detected only at the interface by analytical electron microscopy. The origin of the defects is briefly discussed. © 1996 American Institute of Physics.

    Surface morphology and growth mechanism of YBa2Cu3O7−y films by metalorganic chemical vapor deposition using liquid sources (1996)

    Notes: We have investigated surface morphology of YBa2Cu3O7−y thin films prepared by chemical vapor deposition (CVD) using liquid metalorganic (MO) sources on MgO(100) single crystalline substrates by atomic force microscopy (AFM). An abrupt change in the terrace width was observed at the deposition temperature of around 750 °C. An anomalous decrease in the efficiency of incorporation of the yttrium component into the film was also found above the same temperature. It suggests that the appearance of liquid phase on the growing surface and the growth mode change from the conventional vapor growth to the VLS (vapor–liquid–solid) growth mode at this temperature. © 1996 American Institute of Physics.

    Notes: Abstract. Synapses are central stages for neurotransmission. Neurotransmitters are released from the presynaptic membrane of one neuron, and bind to the receptors accumulated at the postsynaptic membrane, followed by the activation of the other neuron. The strength of a synapse is modified depending on the history of the previous neurotransmissions. This property is called synaptic plasticity and is implicated in learning and memory. Synapses contain not only the components essential for neurotransmission but also the signalling molecules involved in synaptic plasticity. The elucidation of the molecular structures of synapses is one of the key steps to understand the mechanism of learning and memory. Recent studies have revealed postsynaptic density (PSD)-95/synapse-associated protein (SAP) 90 as a core component in the architecture of synapses. In this review, we summarize up-to-date information about PSD-95/SAP90 and its interacting proteins, and the organization of synapses orchestrated by PSD-95/SAP90.

    Simultaneous thermogravimetry - mass spectrometry for a solid oxide fuel cell cathode: (La0.7Sr0.3)0.9MnO3 (1996)

    Notes: Abstract A SOFC cathode related perovskite material, (La0.7Sr0.3)0.9MnO3, has been investigated by simultaneous thermogravimetry - mass spectrometry from room temperature to 1770 K. Water, carbon dioxide and oxygen were detected by mass spectrometry. Water and carbon dioxide evolution can be interpreted by assuming that prior to the thermogravimetry-mass spectrometry measurement about 0.5 % of the lanthanum component had reacted with carbon dioxide and water to form La2(CO3)3*8H2O, which dehydrated and decomposed via La2O2CO3 into La2O3 and evolving H2O and CO2 during the present experiment. The observation that the lanthanum strontium manganite emitted oxygen in two stages can be ascribed to the two different oxygen sites in the perovskite lattice, that is, the oxygen excess and deficient regions.
