A simple expression for the mean-spherical-approximation (MSA) solution of the Ornstein-Zernike (OZ) equation in the Baxter formalism is presented for the case with n components and a single Yukawa term with factorizable prefactor: all coefficients of the MSA solution are given in terms of simple rational functions of…
The ${\mathrm{BaSn}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Sb}}_{\mathit{x}}$${\mathrm{O}}_{3}$ perovskite solid solution exists for 0.0 \ensuremath{\le}x\ensuremath{\le}0.2. The best electrical conductivity occurs for x near 0.15, and is essentially temperature independent from 300 to 5 K. The materials, alt…
The principle of equilibrium potential‐ p H diagrams (Pourbaix diagrams) is extended to the case of two‐dimensional species adsorbed on metals. Up to now, the only solid compounds taken into account in these diagrams have been three‐dimensional compounds. However, species may be adsorbed in E‐p H domains where three‐d…

In the first part of the paper it is shown that the impulse and virial theorems of inviscid incompressible fluid mechanics are special cases of a more general theorem from which an infinity of relations can be obtained. Depending on the problem, only a finite number of these relations may be independent. An applicatio…

We investigated the structural stabilities of eight arid zone soils using percent optical transmittance as a measure of flocculation-dispersion behavior. The soils were sodium saturated and their stabilities determined in sodium chloride solutions of varying concentrations. We treated the soils with hypochlorite for o…

Electrical steels are the most important magnetic materials produced in Europe where the total sales market is around £400 million per annum. Its main use is as the magnetic core material of rotating machines and transformers. When magnetised in such equipment, it dissipates iron losses (as heat) which use up around 5…
Abstract We report high‐resolution XPS data on three forms of the electrochemically synthesized polyaniline films: the highly conducting emeraldine salt form and the films obtained after KOH treatment and electrochemical reduction in HCI. The deconvoluted N 1s peaks in these films show clear evidence of the existence…

We calculate the osmotic pressure in a semi-dilute solution of stretched polymers in a good solvent. The results are applied to polymer brushes where polymers are stretched either directly or by application of shear. It is shown that when a brush is sheared against the solvent, the stretching proceeds always within th…

The p,T-dependence of the self-diffusion coefficient D for methanol, methan(2H)ol and ethanol has been studied between 150 and 450 K at pressures up to 250 MPa. The experiments were performed in strengthened high-pressure glass cells by the application of the nuclear magnetic resonance (NMR) spin-echo technique with p…

X‐ray photoelectron spectroscopy was employed to study surface films generated by anodic electrochemical oxidation of copper in Na 2 SO 4 solutions at p H = 12 . A simple and efficient, low‐cost transfer system is described which allows electrochemical manipulation and transfer of specimens into the vacuum analysis ch…
We have characterized cDNA and genomic clones coding for a sponge collagen. The partial cDNA has an open reading frame encoding 547 amino acid residues. The conceptual translation product contains a probably incomplete triple-helical domain (307 amino acids) with one Gly-Xaa-Yaa-Zaa imperfection in the otherwise perfe…
Escherichia coli, as most Gram-negative bacteria, is insensitive to the photosensitizing action of both lipid-soluble Zinc-phthalocyanine (Zn-Pc) and water-soluble Zinc-mono/disulfonated phthalocyanine (Zn-PcS). Photosensitivity can be induced by alteration of the outer membrane, as obtained by either induction of com…
