Binding energies of carbonaceous overlayers on ruthenium were measured using angle-resolved XPS data and curve fitting procedures. A carbonaceous overlayer prepared by dehydrogenation of adsorbed ethylene at 750 K was disordered and had a binding energy of 285.0 eV. After annealing to 1300 K islands of azimuthally ord…
The degradation of fracture resistance of ferritic steels subjected to neutron irradiation can be qualitatively evaluated by examining the shift in the ductile-to-brittle transition temperature and the drop in the upper-shelf energy as determined in the Charpy impact test. That is an empirical test, however, and its u…
The secondary alcohol oxidase from Pseudomonas sp. catalyzed the oxidation of various vinyl alcohol oligomers with the molecular weight of 220 to 1500 and of β-ketols such as 5-hydroxy-3-heptanone, 4-hydroxy-2-nonanone, 3-hydroxy-5-nonanone, 6-hydroxy-4-nonanone, 7-hydroxy-5-dodecanone, and 8-hydroxy-6-tridecanone. β-…

The complexes [FeIIL(CN)2]·xH2O of the macrocyclic Schiff-base ligands L1–L3 derived from the condensation of 2,6-diacetylpyridine with 3,6-diazaoctane- 1,8-diamine (L1), 3,7-diazanonane1,9-diamine (L2), and 3,6-dioxaoctane-1,8-diamine (L3) have been prepared and their magnetic susceptibilities and Mössbauer spectra s…
Experimental evidence for the formation of Ti 3 B 4 with an orthorhombic Ta 3 B 4 ‐type structure is presented. This phase forms by a peritectic reaction between TiB 2 and liquid at ∼2200°C and is stable to temperatures at least as low as 1690°C, the lowest temperature at which samples were annealed. No evidence was f…
Abstract
In an invariant formulation of pth-grade continuum mechanics, forces are defined as elements of the cotangent bundle of the Banach manifold of Cp embeddings of the body in space. It is shown that forces can be represented by measures which generalize the stresses of continuum mechanics. The mathematical representation…

Abstract Phosphorus transformations that occur after anoxic soils are drained have been associated with acute P deficiencies in rotation crops following rice. Flooded rice may not respond to P fertilization while rotation crops respond markedly to P fertilization on similar soils. The changes that occur among the inor…
The S= 9/2 ground state of a linear MnIICuIIMnII trinuclear complex arises from the parallel alignment of the local spins (5/2) of the two terminal MnII ions through antiferromagnetic interactions with the local spin (1/2) of the central CuII ion.
[Au6(PPh3)6][NO3]2 has been synthesised in low yield from [Au8(PPh3)8][NO3]2 and K[Ag(CN)2] and characterised by a single-crystal X-ray diffraction study. The compound crystallises as [Au6(PPh3)6][NO3]2·3CH2Cl2 in the monoclinic space group P21/a with four formula units in a cell of dimensions a= 25.674(5), b= 15.843(…

Aqueous solutions containing sodium phosphate and sodium molybdate ([P]= 0.01–0.07 mol l–1[Mo] : [P]= 1.25–15) were acidified with concentrated HCl and the formation of molybdophosphate anions was followed by 31P n.m.r. spectroscopy with a view to establishing this technique as an easily applicable method for the iden…
High strength low alloy (HSLA) steels, both commercially available and experimentally prepared, were immersed at 45 and 90 m depths in the North Sea for periods ranging from 1·6 to 7·2 years. General corrosion, pitting corrosion, and crevice corrosion behaviour were evaluated after immersion. The influence of alloying…
Abstract This article presents the experimental and theoretical aspects of small-angle scattering, and discusses specific applications used in the characterization of metals, glasses, polymers, and ceramics. The basic methods of collimating x-rays, the cause of smearing from a line source, desmearing parameters, and t…
Amorphous (noncrystalline) cellulose was prepared by dissolving cotton hydrocellulose in the dimethylsulfoxlde-paraformalde-hyde solvent system and regenerating the cellulose by slow addition of the resultant raethylol cellulose solution to stirred 0.2M sodium alkoxide in methanol :2-propanol (1:1 vol.). The regenerat…
As part of research to develop a highly durable concrete container for radioactive waste disposal in chloride and sulfate bearing granite groundwaters, a variety of cement pastes were studied. A sulfate resisting portland cement was used with various replacement levels of Class F fly ash and pelletized blast furnace s…
