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…
Abstract The interaction of Ni and Fe‐Ni base alloys with the reactive impurities H 2 O, CO, H 2 and CH 4 in simulated cooling gas of the primary circuit of the High Temperature Gas Cooled Reactor (HTGR) causes corrosion effects that can significantly influence the mechanical properties. Apart from the formation of su…
DC and ac electrical conductivities of silicon dioxide thermally grown on p‐ (boron‐doped) and n‐type (phosphorous‐doped) silicon have been measured in the temperature range of 25°–1100°C. Total dc conductivities varied from 10 −9 to 10 −16 Ω −1 cm −1 in the temperature range of 25°–960°C. Arrhenius plots for total dc…

The kinetics of passive film growth on 316 stainless steel in 3% sodium chloride solution have been studied by dc and ac electrochemical measurements. The inverse logarithmic rates of current decay showed two stages of film growth, both controlled by a high field conduction mechanism. Impedance measurements were inter…
The skeletal plates and teeth of the echinoid Paracentrotus lividus contain a heterogeneous assemblage of macromolecules that are not part of the connective tissue, but are presumably intimately associated with the mineral phase. Upon dissolution of the Mg-calcite mineral phase, some of these molecules are insoluble.…
Abstract Finely divided solids can stabilize emulsion droplets provided the solids are partially wetted by both the disperse liquid phase and the continuous liquid phase. The stabilisation of oil/water emulsions by finely divided solids in the presence of suitable organics has been related to the three phase (solid/oi…
