Abstract The spreading rate of a thin film of a liquid on the horizontal surface of an immiscible liquid substrate is calculated by an approximate quasi‐steady analysis. Spreading is assumed to be driven by the combination of gravity and interfacial forces. Dimetryl siloxane fluids of various viscosities were permitte…

Changes in the a -axis and the c -axis thermal resistivity of pyrolytic graphite caused by electron irradiation at 82 K and by subsequent isochronal pulse annealing have been measured. The additive thermal resistivity at 78.5 K increases as 9.6×10 2 N 0.85 f and (7.9±0.6)×10 3 N 0.75 f cm deg/W in the a -axis and the…
In part I it was shown that if the strain energy function was expanded to a sufficient degree and the coefficients Cij were found by regression to pure homogeneous strain data, then stress–strain equations could be derived to give accurate solutions to design problems even at relatively high extensions. The problems o…

Abstract Electron microscope microprobe analysis (EMMA) has been applied to the determination of the elemental compositions of the kaolinite particles (Mg, Al, Si, K, Ti and Fe) contained in the 0·2-0·3 µ m e.s.d., the 0·9-1·0 µ m e.s.d. and the 1·9-2·0 µ m e.s.d. fractions of an English kaolin and an American kaolin.…
Recent progress in the techniques of manufacture of spectroscopic diffraction gratings is described. Three main topics are discussed in detail; (i) the mechanical ruling of gratings, and the way in which the mechanical aspects of the ruling process affect the spectroscopic performance of the grating; (ii) the developm…

Admission as an affiliate requires only membership in a professional society listed here. A…
The magnetic structure of Mn 3 Si (bcc Fe 3 Al type crystal structure) at low temperatures has been determined by neutron diffraction using single crystal samples. It is found that Mn 3 Si has a helical spin structure (Néel temperature 25.8 K) with a wave vector q parallel to one of <111> directions and of magnitude 0…

The dissociation energy of gaseous ZrO, D0° (ZrO), and the heat of atomization of gaseous ZrO2 have been measured using a high temperature mass spectrometer. A number of equilibria were studied and the following results were derived: ΔfH (ZrO,g,298.15 K) =83±12 kJ/mol, D0° (ZrO) =761±15 kJ/mol) (or 7.89±0.15 eV), ΔfH…

An empirical model has been developed to relate molecular weight distribution to the shear dependence of the steady shear viscosity in high-density polyethylene melts. It uses a molecular weight, Mc, which partitions molecular weights into two classes; those below Mc contribute to the viscosity as they do at zero shea…
Sputter-deposited high-purity copper specimens with grain sizes from 8.4 to 0.056 μm were tested in tension to investigate the influence of grain size on yield strength for small grain sizes. The smallest grain size in the sputter-deposited copper was a factor of 40 smaller than the smallest grain size previously avai…
Abstract The Raman scattering is investigated from five phases of AgI that can be reached with moderate pressure and temperature. Particularly noteworthy is the strong negative pressure coefficient of the 17 cm −1 E 2 mode in the wurtzite phase. Its mode gamma is −7.5. The intensity of this mode decreases above 1 kbar…
Values of crystalline-solid Debye temperatures depend both on the method and temperature of measurement. Simple relationships between Debye temperatures and such cohesive properties as compressibility and melting point were derived over 60 years ago by Madelung, by Einstein, and by Lindemann. Debye temperatures ΘXR of…
The crystal structure of YbFe 2 O 4 was determined and refined by the x-ray method. This compound crystallizes trigonal in the space group R [unk] m with the unit-cell dimensions a = 3.455 ± 0.001, c = 25.054 ± 0.010 Å. The unit cell contains three formula units. The structure consists of the alternating layers of YbO…
