The behavior of a cavitation bubble adjacent to a rigid wall is studied numerically with the boundary integral method described in Zhang, Duncan, and Chahine [J. Fluid Mech. 257, 147 (1993)]. In the previous work, the pressure inside the bubble was held constant (this is referred to herein as the empty bubble case). I…
Abstract Depth composition and chemical states of elements constituting the overlayers of Ni x Cr alloys ( x = 0–30 at.%) passivated in borate buffer solutions (pH = 9.2) were determined as a function of the chromium bulk content of the alloy. Depth sputter profiling was performed using both Auger electron spectrosco…
The effect of yttria additions up to 10 wt% on the thermal conductivity of pressureless‐sintered aluminum nitride was investigated. Additions of up to 3 wt% increased the thermal conductivity to values around 160 W/(m·K). Additions higher than 5 wt% slowly decreased the thermal conductivity because of the increasing v…

The evolution of individual He bubbles in thin Al foils during 200-keV Xe irradiation at room-temperature has been followed with in situ transmission electron microscopy. He bubbles were produced by room-temperature implantation of 3-keV He ions into prethinned aluminum samples. During subsequent xenon irradiation, se…
A hierarchically structured hybrid vascular tissue was prepared from vascular cells and collagen. First a hybrid medial tissue was prepared by pouring a cold mixed solution of bovine aortic smooth muscle cells (SMCs) and Type I collagen into a tubular glass mold composed of a mandrel and a sheath (inner diameter, 1.5…
We report x-ray photoemission spectra (XPS) of hydrated nickelic oxide (Ni2O3⋅6H2O). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromatized Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We…

We report x-ray photoemission spectra (XPS) of slightly hydrated Ni(OH)2. XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromatized Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV. We present the…
It is important to systematically assess the severity of a sour environment for susceptibility to sulfide stress cracking (SSC). A prediction system was established based upon SSC as a phenomenon of hydrogen embrittlement (HE). The content of H entering into steel (HFe) could be predicted from the hydrogen sulfide (H2…

Highly uniform, smooth nanocrystalline diamond films have been fabricated with a magnetoactive microwave chemical vapor deposition system. The top and bottom magnet currents were 145 and 60 A, respectively, while the microwave power and substrate temperature were controlled at 1500 W and 850 °C, respectively during de…
Evolution of viscoelasticity in an end-linking gel system has been investigated. Storage and loss dynamic shear moduli, G′(ω) and G″(ω), are determined for angular frequencies ω over more than 2.5 decades near the sol-gel transition. Gelation conditions are varied widely to obtain critical exponents which are independ…
The complex dielectric response of strontium barium niobate relaxor ferroelectrics has been studied as a function of orientation and composition. The dielectric response was found to be strongly dependent on orientation, in distinct comparison to the nearly orientation-independent response found for Pb-based perovskit…
