    Notes:
    Both current-voltage and photoemission measurements of the conduction-band discontinuity of the same InGaP/GaAs p-n heterojunction have been carried out. Interpretation of the current-voltage results using thermionic emission theory applied to a heterojunction bipolar transistor have resulted in a conduction-band offset value of 0.21 eV in the case of a compositionally abrupt junction. This figure has been confirmed by performing independent photoemission measurements on the same junction.

    Notes:
    Wetting and adhesion should be treated as inherently irreversible processes, because, in the process of joining and separating two surfaces, available energy is dissipated. In a system that undergoes inherently irreversible processes, the second law of thermodynamics is always satisfied and can offer no information regarding the system's equilibrium state. Therefore, to determine the equilibrium wetting angle, the law of energy conservation should be used. As a result, the advancing contact angle is found to be intrinsically higher than the receding one, regardless of the surface heterogeneity, and the extent of hysteresis is dependent on the amount of energy dissipated in the process of wetting and dewetting. © 1995 American Institute of Physics.

    Notes:
    Photodissociation of the H2S molecule at 157.6 nm was studied experimentally using the Rydberg tagging technique. Translational energy distributions of the H-atom product from the H2S photodissociation were measured, and the SH(X 2Π)+H(2S) channel was found to be the dominant dissociation process. Spin-orbit and rovibrational state distributions were also obtained for the SH product, which was found to be both vibrationally and rotationally excited. An intriguing bimodal rotational distribution in the lowest two vibrational states, v=0 and 1, has been clearly observed for the SH product, indicating that there are two distinctive dissociation mechanisms involved in the photodissociation of H2S at 157 nm excitation. © 1999 American Institute of Physics.

    Notes:
    Photodissociation of H2O, D2O, and HOD on the A˜ 1B1′ surface through 157.6 nm excitation has been studied using the H(D) atom Rydberg tagging time-of-flight technique. Vibrational state distribution has been measured for the OH/OD product from the photodissociation of the H2O, D2O, and HOD molecules. Comparisons of our results with previous theoretical calculations and experimental results obtained using the laser induced fluorescence (LIF) technique have been made. Experimental results in this work indicate that the relative populations for vibrationally excited OH(v≥2) products measured using LIF are significantly underestimated, suggesting that LIF as a technique to quantitatively measure vibrational distributions of reaction product OH is seriously flawed. The experimental results presented here are in rather good agreement with previous theoretical calculations. However, our results indicate that the calculated vibrational populations for the higher vibrational states of OH are still somewhat overestimated. Relative branching ratio of H and D productions from HOD has also been estimated. This complete set of data for the photodissociation of H2O should provide an excellent testing ground for improving the theoretical potential energy surface of the first electronically excited state of the water molecule. © 2000 American Institute of Physics.

    Notes:
    Abstract The static mechanics requirement for liquids to infiltrate spontaneously into orderly packed monosized spheres or fibres is studied. It is found that a wetting angle much lower than 90 ° is required to achieve spontaneous infiltration, and this wetting angle also varies considerably with respect to the infiltration direction, the arrangement of the fibres or spheres, and the packing density.

    Abstract The sintering behaviour of yttria-stabilized-zirconia (YSZ) gels prepared by a sol-gel process has been studied. The YSZ gels in the forms of bulk and film were sintered at various temperatures up to 1300 °C and the crystalline structures and microstructures were examined by X-ray diffraction and scanning electron microscopy (SEM).
