Reaction between YBa2Cu3O7−x and water
(The American Institute of Physics, 1989-02-01)
Reaction between water at 80 °C and YBa2Cu3O7−x (0.8<x<0.0) is studied using x‐ray absorption fine structure (EXAFS) and x‐ray diffraction (XRD). Oxygen deficient YBa2Cu3O7−x reacts with water and decomposes into BaCO3, ...
Laser cavity mirror imperfections and reflectivity: A time‐dependent numerical approach
(The American Institute of Physics, 1995-01-16)
While the cleaving process used for semiconductor Fabry–Pérot lasers produces atomically abrupt mirrors, there is considerable interest in mirrors defined by etching. Depending on the etching process employed, disorder of ...
An integral method for mixing, chemical reactions, and extinction in unsteady strained diffusion layers
(Elsevier, 1991-02)
An integral method is presented for determining the evolution of molecular mixing, finite rate chemical reactions, and local extinction in diffusion layers under the effect of an unsteady strain rate. The partial differential ...
Two fluid acoustic modes and inhomogeneous cosmologies
(IOP Publishing Ltd, 1993-12-01)
The weak discontinuities that can propagate in a relativistic two fluid system are examined and expressions obtained for their speed of propagation. The acoustic speeds and discontinuity amplitudes are described by their ...
Non-existence of renormalizable self-interaction in N = 2 supersymmetry for scalar hypermultiplets
(Elsevier, 1984-07-23)
We prove that the assumption of invariance under "isospin rotations", i.e. automorphisms of N = 2 supersymmetric charges, implies that there is no local renormalizable interaction among scalar hypermultiplets.
Existence of infinitely-many smooth, static, global solutions of the Einstein/Yang-Mills equations
(Springer-Verlag, 1993-01)
We prove the existence of infinitely-many globally defined singularity-free solutions, to the EYM equations with SU (2) gauge group. The solutions are indexed by a coupling constant, have distinct winding numbers, and their ...
Three‐Dimensional Motion of a Liquid Film Induced by Surface‐Tension Variation or Gravity
(The American Institute of Physics, 1969-10)
Steady flows of a thin layer of viscous liquid on a horizontal plane induced by the nonuniformity of surface tension at its free surface are treated. If the film is very thin, surface‐tension effects dominate gravity ...
The microwave spectrum, ab initio analysis, and structure of the fluorobenzene–hydrogen chloride complex
(The American Institute of Physics, 2003-05-22)
The fluorobenzene–hydrogen chloride π-hydrogen-bonded complex has been studied by high resolution microwave spectroscopy and ab initio calculations. Rotational spectra of the C6H5F–H35Cl,C6H5F–H35Cl, C6H5F–H37Cl,C6H5F–H37Cl, ...
Fractal chemical kinetics: Reacting random walkers
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-09)
Computer simulations on binary reactions of random walkers ( A + A → A ) on fractal spaces bear out a recent conjecture: ( ρ −1 − ρ 0 −1 ) ∞ t f , where ρ is the instantaneous walker density and ρ 0 the initial one, and f ...
