ESR studies of metallocene intercalated Cd2P2S6
(Elsevier, 1988-11-15)
Cd2P2S6 exhibits a layered crystal structure that may be intercalated with metallocenes. The ESR spectra of Cd2P2S6 single crystals intercalated with cobaltocene, nickelocene and chromocene have been examined over the ...
Nonlinear stability of rarefaction waves for compressible Navier Stokes equations
(Springer-Verlag, 1988-09)
It is shown that expansion waves for the compressible Navier-Stokes equations are nonlinearly stable. The expansion waves are constructed for the compressible Euler equations based on the inviscid Burgers equation. Our ...
The anomalous thermal conductivity of La2-xSrxCuO4-y at very low temperatures
(IOP Publishing Ltd, 1988-09-20)
The authors report measurements of thermal conductivity ( kappa ) extending to 100 mK on a series of La2-xSrxCuO4-y specimens with 0.10<or=x<or=0.25. For two superconducting samples (x=0.20, x=0.25) the temperature dependence ...
Flow singularity and slip velocity in plane extrudate swell computations
(Elsevier, 1988)
It is common knowledge that flows of viscoelastic liquids with stress singularities, like the extrudate swell flow, pose formidable obstacles to numerical computations at relatively low Weissenberg number. This paper ...
Combustion of HAN-based liquid monopropellants near the thermodynamic critical point
(Elsevier, 1988-11)
The high-pressure combustion properties of liquid monopropellants involving mixtures of hydroxyl ammonium nitrate (HAN), triethanol ammonium nitrate (TEAN), and water are considered theoretically. Liquid surface properties ...
Amplitudes and cross sections for and heavy lepton production in the effective W approximation
(Elsevier, 1988-11-28)
We give the helicity amplitudes for the process , and examine the validity of the equivalence theorem by comparing longitudinal W scattering with the corresponding unphysical Higgs scattering. We also study the production ...
The dynamics of mesoscopic normal tunnel junctions
(Elsevier, 1988-08-02)
We first review the dynamics of mesoscopic tunnel junctions within the semiclassical approach, outlining the method and its assumptions. We examine the case of a single junction driven by a constant current source, and its ...
Measurement of various terms in the turbulent kinetic energy balance within a flame and comparison with theory
(Elsevier, 1988-05)
Direct measurements have been made of four of the six terms in the exact form of the turbulent kinetic energy (TKE) equation within a premixed turbulent flame, in order to understand how the combustion interacts with the ...
Multiphase extraction: Rapid phase-transfer of [18F]fluoride ion for nucleophilic radiolabeling reactions
(Elsevier, 1988)
In multiphase extraction [18F]fluoride ion for radiolabeling is recovered from target water by passage through a small column of microporous polymer impregnated with a lipophilic cryptand or quaternary ammonium salt. The ...
COMMENT: Glass-like dielectric behaviour of K2CrO4
(IOP Publishing Ltd, 1988-12-30)
It is shown that results on K2CrO4 reported in 1987 by Dissado and Haidar do not invalidate the earlier proposal by Russell and Merlin (1986) of the existence of a high-temperature dipole-glass phase.
