Electric-field-enhanced conductivity in solids

D. M. Pai1975-12-01Journal of Applied Physics

The Onsager theory of dissociation, based upon the solution of Brownian equations of motion of charge carriers interacting through a Coulomb potential in an applied electric field, is shown to account for the electric-field-enhanced conductivity in solids. In contradistinction to often quoted one-dimensional macroscop…

Molecular photoelectron spectroscopy at 132.3 eV. The second-row hydrides

M. S. Banna、D. A. Shirley1975-12-01The Journal of Chemical Physics

Photoemission spectra of the second-row hydrides CH4, NH3, H2O, and HF, as well as Ne, obtained with ultrasoft (132.3 eV) x rays from the yttrium Mζ line and with soft x rays are compared and discussed. The 2s-derived 2a1 or 2σ orbitals show large relaxation energies, as do the 2s orbitals in the free atoms. The high…

Electric field dependence of the magnetic anisotropy energy in magnetite (Fe3O4)

George T. Rado、J. M. Ferrari1975-12-01Physical review. B, Solid state

The application of a static magnetic field to a single crystal of synthetic magnetite (${\mathrm{Fe}}_{3}$${\mathrm{O}}_{4}$) at 4.2\ifmmode^\circ\else\textdegree\fi{}K is found to induce a static electric polarization which is a nonlinear function of the components of the magnetic field and exists even in the absence…

The mechanism of corona and ultraviolet light‐induced self‐adhesion of poly(ethylene terephthalate) film

D.K. Owens1975-12-01Journal of Applied Polymer Science

Abstract The ability of corona treatment to render polyethylene film self‐adherent has been previously reported and the mechanism explained. A similar effect has now been found with corona‐treated poly(ethylene terephthalate) film which adheres strongly to itself when joined under conditions of heat and pressure that…

Differential thermal analysis under high pressure IV: Low‐temperature DTA of solid‐solid and solid‐liquid transitions of several hydrocarbons up to 3 kbar

A. Würflinger1975-12-01Berichte der Bunsengesellschaft für physikalische Chemie

Abstract A DTA apparatus for the temperature range −200°C to +150°C and up to 3000 bar is described. The apparatus is applied to the calorimetric investigation of the phase behaviour of pentane, hexane, heptane, octane, nonane, decane, isopentane, 2,2‐dimethylbutane, 2,3‐dimethylbutane, cyclopentane, cyclohexane, and…

Theory of dielectric relaxation

Daniel Kivelson、Paul A. Madden1975-12-01Molecular Physics

A theory of dielectric relaxation is presented which relates the frequency-dependent dielectric constant to a truly single-particle correlation function. For a sample of suitable geometry, linear response theory is used to relate the polarization to a many-particle correlation function. This correlation function is sh…

Cavitation dynamics: II. Free pulsations and models for cavitation bubbles

H. G. Flynn1975-12-01The Journal of the Acoustical Society of America

A mathematical formalism developed for investigating the dynamics of cavitation bubbles has been used to obtain numerical solutions describing the behavior of bubbles of different initial radii that are damped by heat conduction, viscosity, and compressibility. Calculations have been made to determine two measures of…

Folding in Sepiolite Crystals

Carlos J. Serna、J. L. Ahlrichs、José M. Serratosa1975-12-01Clays and Clay Minerals

Abstract Fibrous sepiolite crystals derive much of their commercial value from their molecular size channels and grooves. The crystals fold upon drying and these channels and grooves are lost. A model for the folding and unfolding of the crystals is presented. Extensive i.r., X-ray and thermogravimetric evidence shows…

Ligand-polarization contributions to the intensity of hypersensitive trivalent lanthanide transitions

S. F. Mason、Robert D. Peacock、Brian Stewart1975-12-01Molecular Physics

The oscillator strengths of the hypersensitive f-electron transitions in lanthanide(III) complexes, the quasi-quadrupolar transitions with intensities sensitive to the ligand environment, are found to arise principally from the coulombic correlation between transient induced electric dipoles in the ligands and the f-e…

Mortar cohesión. The effect of additives

P. Kittll、J. H. Castro1975-12-01Materiales de Construccion

This study was concerned with the hydration of clinker compounds in the presence of different additives; it appeared that accelerating additives, such as calcium chloride and silicic acid, produce longer fibers of tobermorite, whereas inhibitors, such as sugar, produce shorter fibers of tobermorite. This same effect w…

46—THE GEOMETRY, DIMENSIONAL PROPERTIES, AND STABILIZATION OF THE COTTON PLAIN-JERSEY STRUCTURE

J. J. F. Knapton、E. V. Truter、Abdul Karim Aziz1975-12-01Journal of the Textile Institute

Dimensional stability in cotton plain-jersey fabrics can be attained by either mechanical-relaxation techniques (consecutive laundering and tumble-drying cycles) or chemical treatments (fabric mercerization without tension). Both treatments cause large linear-dimensional changes (shrinkage) leading to the same final s…

Pyran copolymer as an effective adjuvant to chemotherapy against a murine leukemia and solid tumor.

Stephen J. Mohr、Michael A. Chirigos、Frederick S. Fuhrman 等 4 位作者1975-12-01PubMed

Pyran (divinyl ether-maleic anhydride) copolymer (NSC 46015) is a polyanion with interferon-inducing and macrophage-stimulating properties, and therefore it has been studied as a possible antitumor agent. Extensive studies using pyran as an adjuvant to chemotherapy against the LSTRA murine leukemia and the Lewis lung…
