Abstract Measurements of permeability and diffusivity have been undertaken for the gases helium and oxygen in a range of highly oriented polyethylene films. The solubilities deduced for both gases are proportional to the amorphous volume fraction, showing that the noncrystalline regions are the transport medium in all…

The effect of surface layer reinforcement with glass fibres of unidirectional jute-rein forced epoxy composite on the flexural properties has been investigated. Substantial increase in flexural modulus and strength with small amounts of reinforcement (for reinforcement ratio (t/d) < 0.3, where "t" and "d" are the r…

First we demonstrate that the extended mean-field model suggested by Huang and Viner is necessary and sufficient to describe the nature of the smectic-A--smectic-C (or --chiral-smectic-C) transition. The rest of the expansion terms in the mean-field free energy can be treated as higher-order correction terms. Then a g…

Abstract. A new method is described for determining the boundary layer resistance over wet filter paper exposed within a leaf cuvette, based on the energy balance of the filler paper. The boundary layer resistance is calculated by an iterative procedure from measurements of the relative humidity and temperature of the…

Abstract A recent development in homogeneous catalysis is the discovery of catalysts that are active for the lithiation of 1‐alkenes to alkenyllithium compounds and lithium hydride as well as for the hydrogenation of lithium and magnesium under mild conditions. The catalytically prepared magnesium hydride is highly re…

We have succeeded for the first time in artificially tuning the conduction and valence-band barrier heights at an abrupt intrinsic semiconductor-semiconductor heterojunction via a doping interface dipole (DID). This is achieved by means of ultrathin ionized donor and acceptor sheets in situ grown within ≲100 Å from th…
Two analyses are presented for the sintering kinetics of a porous glass layer on a rigid substrate. The first treatment uses a continuum model, with constitutive equations and the free strain rate derived from an appropriate microstructural model. Predictions are obtained for the sintering kinetics and the magnitude o…

Abstract The sorption and the permeation of iodine in water‐swollen poly(vinyl alcohol) (PVA) membranes and the formation of PVA–iodine complexes were studied. The logarithms of the permeability and the diffusion coefficient decreased approximately linearly with the increase in polymer volume fraction. When the membra…
Recent observations with both magnesia‐ and yttria‐partially‐stabilized zirconia (Mg‐ and Y‐PSZ) indicate an apparent anomaly between strength and toughness relations in these materials. The present communication attempts to rationalize these observations and suggests that the stress to initiate the tetragonal‐to‐mono…
This paper reports the results of an investigation into the effects of various environmental factors on CO2 corrosion of 9 to 25% Cr steel, with emphasis on the finding that each alloy has application criteria based on critical temperatures and CO2 partial pressures in a CO2-Cl− environment. It is also shown that each…
