We report x-ray photoemission spectra (XPS) of potassium nickel (IV) hexaoxidoiodate (VII). XPS spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer using unmonochromated Mg Kα x rays at two pass energy settings corresponding to analyzer energy resolutions of 1.34 and 0.54 eV…

Infrared spectra of free molecules of 4-nitroaniline, 2-chloro- and 2,6-dichloro-4-nitroanilines and their H-bonded complexes (1:1) with acetonitrile, dimethylformamide, dimethyl-sulphoxide and hexamethylphosphortriamide have been investigated in spectral region of aminogroup stretching vibrations in CCl 4 medium. Spe…
To suppress the reactivity of ALN powder with water, chemical surface modification with carboxylic acids has been investigated. It was found that the chemical stability of ALN powder increased as the number of carbon atoms in carboxylic acids used for the surface treatment increased. Among the carboxylic acids tested,…
In gas production wells, carbon (C) steel tubulars subject to carbon dioxide (CO2) corrosion have been replaced gradually with corrosion-resistant 13% chromium (Cr) steel of the martensitic type (AISI type 420 [UNS S42000]), eliminating the need for inhibition and possibly extending tubular lifetime. The effect of mat…
The surface precipitation process of epitaxially grown graphite (0001) layers on the C-doped Ni(111) surface has been investigated by in situ x-ray photoemission spectroscopy measurements. Peak intensity measurements at various temperatures clarified the change of the carbon chemical state from the segregated carbon t…
The Optical Fibre Diameter Analyser (OFDA) instrument is based on automatic image analysis technology and was recently introduced to provide a rapid, accurate measurement of average fiber diameter (AFD) and diameter distribution (SD) of textile fibers. Experiments were conducted with wool and mohair in various physica…
Nickel by Mg Kα XPS Nickel spectra were measured with the Physical Electronics Model 5400 x-ray photoelectron spectrometer (XPS) using unmonochromatized Mg Kα x rays and four pass energy settings corresponding to analyzer energy resolutions of 1.34, 0.54, 0.27, and 0.13 eV. The specimen is a high purity (99.95%) 4 μm…

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…
