    Notes:
    Reactions at Ti/Cu interfaces were investigated by ultraviolet and x-ray photoelectron spectroscopy (UPS, XPS). For Ti deposition onto copper substrates at ambient temperature, our measurements strongly suggest that at the interface an amorphous alloy is formed. This idea is supported by the comparison of our UPS data to the ones of bulk glassy CuxTi1−x. The thickness of this amorphous interlayer which is built up onto the polycrystalline Cu substrate corresponds to a nominal Ti coverage of about 10 monolayers. At a substrate temperature of 300 °C, however, the interface reaction is still present at nominal Ti coverages over a hundred monolayers. Presumably the crystalline phase Cu3Ti2 is formed. © 1998 American Institute of Physics.

    Notes:
    The influence of the substrate potential with respect to the plasma on the morphology of reactively sputtered TiN thin films on Si(100) has been investigated. It is well known that the film quality with respect to grain size and distribution can be improved by applying a negative substrate bias to increase energetic ion bombardment. For large-area applications, however, a grounded substrate is very much desirable. Therefore, a technique has been developed to deposit films with comparably improved morphology on grounded substrates by means of a so-called "plasma electrode." Grain size and distribution have been analyzed by top- and side-view scanning electron microscopy. To adjust the parameters for the TiN deposition we have used in situ photoelectron spectroscopy as the process control. © 1999 American Institute of Physics.

    summary  The purpose of this study was to determine the optimal thread form configuration for an experimental stepped screw implant. Two-dimensional finite element analysis was applied to model the experimental stepped screw implant in a standard cross-section of the posterior human mandible digitized from a CT-generated patient data set. Four different thread form configurations: v-thread (V), thin-thread (T), and two square-thread forms of 0·24 mm (S1) and 0·36 mm (S2) thread width were compared under oblique load in normal cortical bone condition. The support-type constraint position changed from middle to the base of the bone segment. In middle support-type constraint position only the thin-thread (T) model demonstrated significantly different stress distribution from the other three models, however, in base support-type constraint position T and S1 models demonstrated significantly different stress distribution from the other two models. The results implies that v-thread (V) or large square-thread (S2) are optimal thread form for the experimental stepped screw implant. While, minimal support constraints allow clearer differentiation of the stress picture between the different stepped screw types at the trabecular bone–implant interface.

    Notes:
    Abstract The motion of dust suspensions accelerated by shock waves has been experimentally investigated in a vertical shock tube, in which a completely developed plane shock wave of moderate strength propagates into a homogeneously distributed dust suspension with a planar interface. Trajectories of the accelerated interfaces as well as transmitted and reflected shock waves are recorded by using a shadowgraph system with a Cranz-Schardin camera. Two kinds of particle samples, i.e. porous lycopodium particles 30 μm in diameter and corn starch particles with a mean diameter of 10 μm, are employed. The effects of shock wave strength and particle loading ratio are also examined. Experimental data are compared with theoretical results, and the agreement is good.

    Notes:
    Abstract The linear relation between the particle concentration and the output voltage of a light extinctiometer used to measure particle concentrations has been derived and calibrated. A time integration method was introduced to determine the characteristic parameter of such a measuring system. This characteristic parameter which is proportional to the extinction coefficient is found to be in good agreement with its theoretical value. As an example, in a vertical tube the increasing particle concentration was measured behind a developing flat interface between a gas and a gas-particle mixture as a function of time.

    Notes:
    Abstract The acceleration by an incident shock of a planar interface between a gas and a particle-gas mixture has been investigated experimentally and numerically. The experiments were conducted in a newly developed vertical shock tube in which the planar interface of the particle-gas mixture was generated and its particle concentration history was measured. Polydisperse corn starch particles with a mean diameter of 10μm were used. We recorded the motion of the interface, as well as of the incident and reflected shock by using a 4 channel spark shadowgraph. The experimental conditions were Mach numberM s=5.15 and initial pressurep 1=50kPa for various particle concentrations in nitrogen. The reflected shock appears with a delay after the incident shock enters the particle-gas mixture. Numerical methods were employed to solve the two-phase governing equations. Experiments and numerical solutions are in good agreement.
