Anion voidage and anion void lattice formation in electron irradiated (100 keV–1 MeV) fluorite (CaF2) has been investigated by in situ transmission electron microscopy. At low fluences (≲1 dpa) the damage consists of randomly distributed anion voids and large bubble-like defects associated with fluorine gas. At higher…

Nous considérons un solide poreux, ou un gel, saturé par un système fluide à deux composants, A, B, dans le domaine de température où A et B démixent; l’épaisseur 03BE de l’interface est supposée plus petite que la taille des pores. Le solide préfère être en contact avec la phase riche en A. Mais, si l’on fait décroît…

A theoretical and experimental study of potential gradients in crevices between a piece of steel and an insulating coating has revealed that the condition of the steel surface and the potential of the steel at the coating holiday have important effects on the potential gradient. Holiday potentials more negative than t…
Articles by 75 leading authorities cover virtually every aspect of composite materials and provide detailed information on methods of manufacturing properties, uses of composite materials and components. Entries include tables, figures, and extensive references. Alphabetical organization, cross-referencing, and a deta…
Abstract Theoretical investigation shows that a transition in the solid state from form I to form II affects the solubility of a solid in a liquid. Experimental results for the solubility of phenanthrene in pyridine, which has a lambda‐point transition between 331 and 361 K, conform generally to the theoretical predic…
Proteins from the axonemes and disc cytoskeleton of Giardia lamblia have been examined by sodium dodecyl sulphate/polyacrylamide gel electrophoresis. In addition to tubulin and the 30 X 10(3) molecular weight disc protein, at least 18 minor components copurify with the two major proteins in Triton-insoluble structures…
Very hard diamondlike carbon films have been prepared with the aid of an ionized deposition technique. The growth mechanism of films deposited in the presence of methane gas is discussed. The properties of these carbon films are as follows: The concentration of hydrogen atoms contained in the films is almost negligibl…
Abstract
An unusual trimeric CuII species of formula [Cu3(OH)(pz)3(Hpz)2(NO3)2]·H2O (Hpz = pyrazole) has been prepared from air oxidation of [Cu(Hpz)2(NO3)] in the presence of moisture. The X-ray structure of the oxidation product has been determined by single-crystal diffractometer techniques, and has been compared with a few…
An equivalent electrical circuit that describes the electrode processes on different electrolytes, using porous Pt electrodes, is given. Diffusional processes are important and have to be presented by Warburg components in the circuit. The overall electrode process is rate limited by diffusion of atomic oxygen on the…
The mechanism of a field induced transition from helical Sm C∗ to Sm C structure in a DOBAMBC liquid crystal situated between two glass plates has been studied by optical methods. The important role of a regular system of twist disclination lines (dechiralization lines) in unwinding the helical structure by electric f…
The charge-transfer band is determined from reflectance measurements on single crystals of TTF-chloranil from 300 to 45 K, passing through the neutral-ionic phase transition at 84 K. As the temperature is decreased from 300 K toward the transition, hνCT decreases slowly from 0.66 to 0.55 eV, perhaps the lowest energy…

The (Gell–Mann–Low type) renormalization group theory is applied to frictional properties of dilute polymer solutions for the first time. The universal ratios such as Flory’s intrinsic viscosity constant, the Flory–Scheraga–Mandelkern parameter, etc., are estimated from the first order ε-expansion theory (ε=4−d, d bei…
A second ‘premartenaitic’ effect in a Ti50Ni47Fe3 alloy was found to occur approximately 12°C below the onset of the initial ‘normal-to-incommensurate’ transition described in the previous paper. This subsequent phase change involves a structural transition from a ‘distorted’ CsCl parent to a rhombohedral product, dur…
Topics discussed in this book include modelling the effects of fire, ablation, heat flow in porous rock, thermal stress and dissolving coal. Alternative energy sources such as geothermal reservoirs and solar radiation are also discussed. Includes bibliographies at the end of the papers, a cited author index, and a sub…
The electrode behavior of Pt‐sputtered and PT‐gauze electrodes on ZrO 2 ‐ Y 2 O 3 , Bi 2 O 3 ‐ Er 2 O 3 , and CeO 2 ‐ Gd 2 O 3 solid electrolytes was investigated by means of d‐c measurements in the temperature region of 770–1050 K and in the oxygen partial pressure region of 10 − 5 – 1 atm O 2 using N 2 ‐ O 2 mixture…
Five new classes of crystalline, hydrocarbon-soluble group 3A metal (M) aryloxides are reported: [M(OAr)3], (1), [M(L)(OAr)3][L = tetrahydrofuran (thf) or P(O)Ph3], [M(OAr)2(µ-OAr)2Na(thf)2], Li[Yb(Cl)(OAr)3], and [{Y(Cl)(OAr)(µ-OAr)}2](Ar = C6H2Me-4-But2-2,6), ranging for (1) from M3+ being the 3d°, 4d°, to the 4fn(n…
