Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun The ability or power to conduct or transmit heat, electricity, or sound.
- noun The conductance of a material.
- noun Physiology The conductibility of a structure, especially the ability of a nerve to transmit a wave of excitation.
from The Century Dictionary.
- noun In physiology, the power of a nerve to conduct an impulse.
- noun The thermometric conductivity of the atmosphere; the change in temperature of the atmosphere due to its calorimetric conductivity. It is equal to the latter divided by the specific heat of a unit volume, or by the product of the specific heat of a unit mass multiplied by the density of the gas. It is therefore a large quantity in the upper regions of the atmosphere.
- noun In physics, the power of conducting heat, electricity, or sound; the property of being conductive.
from the GNU version of the Collaborative International Dictionary of English.
- noun The quality or power of conducting, or of receiving and transmitting, as heat, electricity, etc..
- noun (Physics) the quantity of heat that passes in unit time through unit area of a plate whose thickness is unity, when its opposite faces differ in temperature by one degree.
- noun (Physics) the thermal conductivity when the unit of heat employed is the heat required to raise a unit volume of the substance one degree.

"Specifically, we've shown that the hybridization of electronic wave functions of alloy constituents in HMAs makes it possible to enhance thermopower without much reduction of electric conductivity, which is not the case for conventional thermoelectric materials," he says.
