Mechanics of transport phenomena in multi-component sessile drops with solidification
(Elsevier, 1990)
An experimental study is performed to determine the mechanics of transport phenomena in multicomponent sessile drops with internal solidification. These drops are cooled at the center of the drop base or over the enter ...
Bimolecular reaction A + B --> 0 at steady state on fractals: Anomalous rate law and reactant self-organization
(Elsevier, 1990-10-01)
This paper is a theoretical investigation of the diffusion limited reaction A + B --> 0 at steady state and on fractal structures. We propose an extension of a scheme previously applied to Euclidean spaces, using the ...
Asymptotic analysis of the shock wave ignition of dust particles
(Elsevier, 1990-09)
The critical energy required to initiate dust detonations in tubes of finite diameter depends on the structure of the reaction zone, and especially upon the length of the induction zone, which, in turn, is determined by ...
Possible mechanisms for nonlinear de Haas-van Alphen oscillations in heavy fermion compounds
(Elsevier, 1990-04)
Three possible many-body mechanisms giving rise to de Haas-van Alphen oscillations with frequencies that correspond to linear combinations of ordinary closed orbits of the Fermi surface are discussed in the context of ...
A test particle approach in the stochastic stability analysis of charged particle beams
(Elsevier, 1990-01-15)
The stochastic stability of a charged particle beam propagating in a randomly unhomogeneous medium is analyzed using an internal test particle approach. The effect of the random medium is included by adding a stochastic ...
The ne plus ultra of tree graph inequalities
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-05)
With nary mention of a tree graph, we obtain a cluster expansion bound that includes and vastly generalizes bounds as obtained by extant tree graph inequalities. This includes applications to both two-body and many-body ...
Wavelength selective detection using excitonic resonances in GaAs/AlGaAs P-I-(MQW)-N structures
(Elsevier, 1990)
The quantum confined Stark effect causes a strong wavelength and voltage dependence of photocurrent near excitonic resonances which is used to study the wavelength selectivity of p-i(MQW)-n photodiode. For a parallel input ...
ESR studies of inter- and intra-lamellar cation exchange processes in Cd2P2S6
(Elsevier, 1990)
The transition metal chalcogenides, M2P2S6 (M = divalent transition metal cation), are lamellar materials that undergo an unusual cation exchange process when their crystals are placed in contact with a solution of a ...
The construction of the L3 experiment
(Elsevier, 1990-04-01)
The L3 experiment is one of the six large detectors designed for the new generation of electron-positron accelerators. It is the only detector that concentrates its efforts on limited goals of measuring electrons, muons ...
An automatic focus/hold system for optical microscopes
(The American Institute of Physics, 1990-12)
A system for maintaining long‐term focus of samples under high‐magnification quantitative observation in an epi‐illumination optical microscope is described. A negative feedback signal is generated from focus‐dependent ...
