The localised corrosion behaviour of 17–4 PH (precipitation hardenable) stainless steel, in the solution annealed, aged, and overaged conditions, was studied in acidic chloride and sulphuric acid media using the potentiodynamic anodic polarisation method. Electrochemical potentiokinetic reactivation (EPR) studies and…
Abstract The use of XPS data for accurate elemental quantitation requires that the transmission function of the electron spectrometer be known. Often, the dependence on electron kinetic energy ( E k ) and spectrometer pass energy ( E a ) are treated as separable functions. This is inadequate for the comparison of data…
Abstract Epoxidation of cyclooctene with molecular oxygen was achieved using electrochemically reduced metalloporphyrins in N,N-dimethylformamide (DMF) containing acetic anhydride as an electrophile. Turnover numbers 5–7 based on moles of cyclooctene oxide produced per moles of porphyrin were obtained by the use of [5…
Proper roll cooling has been identified as a critical factor in the problems of excessive roll spalling and poor thermal crowning in modern, high-speed rolling mills. In this paper, an analytical model has been developed to determine the temperature profiles of the roll and the strip. This model uses basic heat transf…

For pt.I see ibid., vol.6, no.2, p.16-22 (1990). In the first part it was shown that the virtually universally observed relaxation behavior of solid dielectrics is radically incompatible with the classical Debye behavior. It was also pointed out that the widely accepted interpretation in terms of distributions of rela…
The compounds YTi(Fe1−xCox)11 form complete solid solutions (0≤X≤1) all of which crystallize in the ThMn12-type tetragonal structure. The substitution effects of Fe with Co on saturation magnetization and Curie temperature have been investigated. A neutron-diffraction study has been carried out on YTiCo11 and YTi(Co0.…
The rates of densification and the mechanical properties of pure Al 2 O 3 and ZrO 2 ‐toughened Al 2 O 3 (ZTA) have been investigated as a function of the temperatures and time schedules used for hot isostatic pressing (HIP) as a postsintering heat treatment for samples which had already been pressureless sintered in a…
Ultrafine and nearly spherical particles of zinc ferrite were synthesized under mild hydrothermal conditions by precipitating from metal nitrates. These particles exhibited antiferromagnetic ordering below 13 K. Mössbauer spectroscopic measurements revealed the subdomain superparamagnetic nature of the particles havin…
The magnetic and crystallographic properties have been investigated for NdCo4M (M=B, Al, and Ga). The temperature dependencies of lattice parameters have been determined between 80 and 730 K by x-ray diffraction. NdCo4B crystallizes in the CeCo4B-type structure, whereas NdCo4M (M=Al and Ga) exhibits a CaCu5-type struc…
A study has been made to investigate the effect of propargyl alcohol (PA) on corrosion and hydrogenation of mild steel exposed in hydrochloric acid solution at different temperatures, concentrations, and exposure times. Different ions have been added to the inhibited acid solution to study their roles on the inhibitiv…
Sm-Co-based sputtered films have been deposited that exhibit a remanence ratio for hysteresis loops measured out of the plane to in the plane of 0.04. These results have been obtained by thermalized sputtering this system in Ar, Ar+Xe mixtures, and in Xe. The use of Xe has allowed a more efficient thermalization of th…
The surface-enhanced Raman spectrum of 2,2’-bipyrimidine adsorbed on silver sol has been obtained and analyzed by using a vibrational assignment previously determined for this azoaromatic molecule. Evidence was found for Ag-N bond formation with the silver substrate and a model is proposed for the adsorption on the ba…
Orbital angular momentum is necessary in order to have magnetic anisotropy. In a magnetic system, orbital angular momentum is caused by spin-orbit coupling as well as by many-body correlation effects. Standard band-structure calculations only include the first of these two contributions. In this paper it is argued tha…

Rosette‐shaped clusters of barite crystals were found on the depositional surface and in the inner, complex crossed‐lamellar shell layer of Corbicula fluminea collected from the Maurice River, New Jersey. Morphological analyses revealed that barite crystallized directly from the extrapallial fluid onto the inner shell…
Magnetic and structural characteristics of RCo5−xAlx have been established for R=Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Er, and Tm. All systems have the CaCu5 structure. Al and Co are randomly distributed over the Co-sublattice sites. Al-substitution decreases μCo and Tc and significantly alters magnetic anisotropy. Analysis…
