Transient nucleation and bubble growth in immiscible liquid composites induced by counterdiffusion of gases
(Elsevier, 1981)
Supersaturation, homogeneous nucleation, and subsequent bubble growth and motion in immiscible liquid layers induced by counterdiffusion of gases at different temperatures are studied analytically. The range of the critical ...
Electrochemical reduction off 4-aminopyrimidine in aqueous media
(Elsevier, 1981-12)
The redox and associated chemical behavior of 4-aminopyrimidine (4-AP) and its reduction products in buffered aqueous media have been examined by a variety of electrochemical techniques. In acidic medium (pH 0-2), 4-AP ...
Electron–nuclear double resonance on copper (II) tetraimidazole
(The American Institute of Physics, 1981-09-01)
We have investigated the electron–nuclear double resonance (ENDOR) from frozen aqueous solutions of 65Cu++(imidazole)4, 65Cu++ (imidazole–15N)4, and 65Cu++(imidazole–Dn)4, where n = 1, 2, 3, and 4 for selectively deuterated ...
Some nonlinear optical phenomena
(The American Institute of Physics, 1981-09)
Some nonlinear optical phenomena are investigated, especially stimulated scattering, from the point of view of the kinetic theory of radiation (i.e., photon transport theory). Kinetic theory provides a perspective, different ...
Pressure enhancement of the electrical conductivity of graphite intercalation compounds
(IOP Publishing Ltd, 1981-10-30)
A novel approach to achieve high electrical conductivity in graphite intercalation compounds is suggested. It is based on a recently observed pressure-induced staging transition in GICs which leads to a higher areal density ...
MHD stability of toroidal plasma with modulated curvature planar magnetic axis
(IOP Publishing Ltd, 1981-05-01)
The authors study the equilibrium and analyze Mercier's criterion of stability (Mercier, 1964) near an arbitrary modulated curvature planar magnetic axis (with zero torsion and variable curvature) of non-circular (elliptically ...
Coverage‐dependent surface enhanced Raman spectra of halide ions on colloidal silver
(The American Institute of Physics, 1981-10-15)
Surface enhanced Raman spectra of halide ions on colloidal silver as a function of coverage is obtained. (AIP)
Electromagnetic effects in the surface enhanced Raman scattering from a molecule at a liquid Hg surface
(Elsevier, 1981-09-02)
In a previous publication the image enhancement effect and the enhanced radiation due to near field excitation of surface roughness were calculated for a finite-size molecule above a metal described by a nonlocal dielectric ...
On some properties of solutions of Helmholtz equation
(The American Institute of Physics, 1981-02)
We give a new method to prove results of the following type. Let: (∇2 + k2)u=0 in DR={x‖x‖?R}, k2≳0. (1) If u∊L2(DR), then u≡0 in DR. (2) If ‖x‖mu(x)→0 as ‖x‖→∞, x21+⋅⋅⋅+x2N−1?cx−2pN ,p≳0, m=1, 2, 3,..., ‖x‖[(∂u/∂‖x‖)−iku‖x‖→∞]→0, ...
