Intrinsic conductivity of conducting polymers
Synthetic Metals, 1988Because the charged dopant ions are spatially separated from the quasi-one-dimensional conduction path in conducting polymers, resistive back scattering is suppressed. In the case of high molecular weight and relatively few sp3 defects, even relatively weak interchain coupling is sufficient to avoid one-dimensional localization; this leads to coherent ...

Conductivity and photoconductivity of conducting polymers
Physica Scripta, 1992A review is presented of the state of the art of conducting polymers. Special attention is given to the high electrical conductivity of highly ordered doped polyacetylene, to the attempts to reproduce σ-values above 105 S/cm, and to efforts to correlate the electrical conductivity with other physical parameters (European Brite/Euram Project HICOPOL).

Conducting Polymers: Electrical Conductivity
2007Abstract : While undoped polymers are insulators, doped conducting polymers have conductivities comparable to conventional metals and semiconductors despite their polymer chain structure. Models for the doping induced insulator-metal transition and the metallic conductivity of conducting polymers are introduced.

Neuroid Conduction and the Evolution of Conducting Tissues
The Quarterly Review of Biology, 1970Neuroid conduction, as here defined, refers to the propagation of electrical events in the membranes of non-nervous, nonmuscular cells. Examples from protistants, plants, and animals are described. In the dinoflagellate Noctiluca, propagated membrane depolarizations accompany the spread of the luminescent response, and local electrical changes are ...

Conductance of a Single Conducting Polyaniline Nanowire
Acta Physico-Chimica Sinica, 2005The combination of template synthesis method of nanowire/nanotube and conductive atomic force microscopy (C-AFM) is an efficient way that can be used to probe the conductivity of single one-dimension nanomaterial and its array. This communication reports the conductivity of an electrochemically prepared single polyaniline(PANI) nanowire determined ...

Governing the conduct of conduct: are restraints inevitable?
Journal of Advanced Nursing, 2002Background. The purpose of this article is to provide an interpretation of how restraint use is maintained and legitimized despite negative reports on its efficacy and questions about its ethicality. My research examined the use of restraint on a patient requiring care in an acute teaching hospital in Australia.

Conductive mechanisms in electrical conductive adhesives with isotropical electrical conductivity
2011 IEEE 17th International Symposium for Design and Technology in Electronic Packaging (SIITME), 2011Electrical conductivity of electrically conductive adhesives is controlled with three mechanisms. These mechanisms are described — a phonon-electron interaction, a constriction mechanism and a tunnel mechanism. If the phonon-electron and constriction mechanisms dominate; the temperature dependence of resistivity is positive and linear, and the ...

Conduction modelling of a conductive adhesive with bimodal distribution of conducting element
International Journal of Adhesion and Adhesives, 1999It is shown by the electric network percolation theory, that the isotropic conductive adhesive (ICA) using a bimodal distribution of metal fillers is expected to have a decreased metal loading for better mechanical performance while its electrical and manufacturing processing properties remain unchanged.
