Impurity bands in superconductors with magnetic impurities

Solid State Communications, 1972
Abstract We discuss and calculate impurity bands in superconductors with magnetic impurities. It is shown how their existence is related to the Kondo effect.

Impurities and impurity transport in the spheromak SPHEX [PDF]

open access: possiblePlasma Physics and Controlled Fusion, 1997
Absolute spectroscopic measurements are made of all significant ionization states of the dominant impurities in SPHEX during sustained operation, and these are compared with a diffusive transport model to derive average plasma parameters. Statistical tests are used to establish the reliability of these results.

THE ART OF IMPURITY

Ethics & the Environment, 2003
I was taken aback when I received a request from the West Australian government to write a response to the question, "What Is The Ethical Foundation For Planning A More Sustainable Future?" My first reaction was: Does not every one want a future? And doesn't this necessarily mean a commitment to sustainability ? Would not everyone earnestly want a more

Impurity levels induced by a C impurity in GaAs

Physical Review B, 1986
We have used the Watson-sphere-terminated molecular-cluster model within the framework of the multiple-scattering X\ensuremath{\alpha} theory to carry out electronic-structure calculations of a carbon substitutional impurity in GaAs. The activation energy of the ${\mathrm{C}}_{\mathrm{As}}$ impurity level is calculated as a function of inward ...

Impurities in snowpacks

Environmental Monitoring and Assessment, 1989
Snow can be involved in the acquisition, transport, storage and release of atmospheric impurities. Because it can store impurities for periods of time ranging from hours to millenia, it provides a medium for monitoring atmospheric impurities for a wide range of time scales.In most climates, snow is involved in the precipitation process.

Impurities in ether

The American Journal of Surgery, 1939
T HERE is a great Iack of information both on the occurrence and on the effects of impurities which may occur in ether. Only since 1925 have cases of so-called ether convuIsions been reported in the literature. The EngIish have emphasized two factors which have been present in the majority of cases reported: (I) the patients have been young and (2 ...

Impurity in Halothane Anesthetic

Science, 1963
A halogenated butene has been isolated from commercially available halothane (Fluothane). Its concentration increases under the conditions in which halothane is commonly used in clinical work.

Impurity-impurity interactions in dilute alloys

Hyperfine Interactions, 1990
The interaction between impurities of two solute elements in metal hosts leads to a non-random distribution of impurity atoms among the lattice sites. Experimental studies of this distribution provide quantitative information on the energy involved in the formation of an individual impurity-impurity pair.

Calculation of impurity-vacancy and impurity-impurity interactions from enhancement of solvent and solute diffusion

Physical Review B, 1986
The enhancement of solvent as well as solute diffusion is discussed for substitutional alloys with impurities of positive excess charge as a function of composition and temperature. The enhancement factors of solvent diffusion up to third order in the impurity concentration and the corresponding enhancement factors of solute diffusion up to second ...
