The dissociation of O2 on Ni(100) has been studied using a cluster model approach. The three principally different reaction pathways, over an on-top position, over a bridge position, and over a fourfold hollow position, were considered. The dissociation mechanisms were found to be very similar for these pathways. In t…

The orientational freezing of a system of hard ellipses, as a first approximation for a nematogen adsorbed on a smooth substrate, is studied with the aid of an approximate density-functional theory used previously for the study of hard ellipsoids. The isotropic-nematic transition, which was first order for the ellipso…

Modulated phases that occur in tilted chiral smectic liquid crystals are discussed within mean-field theory in thin films and in bulk. A chiral term in the free energy containing three order parameters and one gradient can make the free energy of certain defects negative or the bend elastic constant negative. Assuming…

A review is presented of the research and development effort that has been aimed at providing new stainless steels for use in seawater and seawater-cooled systems. Three new categories of highly corrosion-resistant stainless steels are described, namely the superaustenitics (i.e., austenitic nitrogen-containing 6% mol…

The hydrothermal reaction of Na2MoO4, Mo, H3PO4, Et4NOH, and H2O yields the title complex, the structure of which is characterized by tetramers of [Mo6P4O24(OH)7]5⊖ units 1 (Mo = hatched, P = dotted, O = empty circle). The complex structure of the reduced molybdenum phosphate can be rationalized by the differing hydro…

We have re-analyzed the dynamics of the ring spinning process as a coupled set of subproblems and have obtained the solutions numerically. The analyses in Parts I and II of this series deal with the case of an uncontrolled balloon. In Part I we ignore the effects of air drag as well as gravitational and Coriolis accel…

Phase matched second harmonic generation was observed in a ferroelectric liquid crystal mixture. An electric field was applied parallel to glass plates of a homeotropically aligned cell in order to introduce a uniform alignment of the directors and the permanent dipoles. The phase matching was performed with an extrao…

Substitution of a lysyl residue for Arg-386 of Escherichia coli aspartate aminotransferase resulted in an extensive decrease in Vmax values (0.8% with the aspartate-2-oxoglutarate pair and 0.2% with the glutamate-oxalacetate pair, compared with the corresponding values for the wild-type enzyme).

Phase‐transformation‐induced compressive surface stresses were introduced into ceria‐doped tetragonal zirconia polycrystals by reduction of CeO 2 . Four‐point‐bending strength of sintered ZrO 2 containing 12 mol% CeO 2 increased from 240 to 545 MPa after it was annealed at 1400°C for 2 h in nitrogen. The strength of t…

Lead titanate ceramics modified with 24, 30, 35 and 40 mole% of calcium have been obtained. The thermal behaviour of permittivity as well as that of pyroelectric coefficient present a larger broadening the larger the Ca content, which could be adscribed to an increasing disorder on the Ca and Pb arrangement. On the ot…

Diamond films doped with boron were fabricated by the thermal filament CVD method. Powdered B 2 O 3 was used as the doping source. The films were identified as diamond by means of several methods including Raman spectroscopy. The resistivity of the films was inversely proportional to the B / C ratio over four orders.…
