• Conductivity near the percolation threshold — In a mixture between a dielectric and a metallic component, the conductivity σ and the dielectric constant ε of this mixture show a critical behavior if the fraction of the metallic component reaches the percolation threshold.[1] The behavior of… …   Wikipedia

• Conductivity (electrolytic) — The conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and… …   Wikipedia

• Molar conductivity — is defined as the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte, and so measures the efficiency with which a given electrolyte conducts electricity in solution. Its units are siemens per meter per… …   Wikipedia

• Thermal conductivity measurement — Two classes of methods exist to measure the thermal conductivity of a sample: steady state and non steady state methods. Steady state methods (In Geology/Geophysics)The most common method for consolidated rock samples is the Divided Bar. There… …   Wikipedia

• Limiting molar conductivity — See Kohlrausch s Law for details this is the conductivity of an ionic substance which has been extrapolated to an infinite dilution. It is normally the case thatMolar conductivity = Limiting molar conductivity Kc1/2c is the concentration of the… …   Wikipedia

• Meissner effect — Diagram of the Meissner effect. Magnetic field lines, represented as arrows, are excluded from a superconductor when it is below its critical temperature. The Meissner effect is the expulsion of a magnetic field from a superconductor during its… …   Wikipedia

• Color superconductivity — is a phenomenon predicted to occur in quark matter if the baryon density is sufficiently high (well above nuclear density) and the temperature is not too high (well below 1012 kelvin). Color superconducting phases are to be contrasted with the… …   Wikipedia

• Magnetoresistance — is the property of a material to change the value of its electrical resistance when an external magnetic field is applied to it. The effect was first discovered by William Thomson (more commonly known as Lord Kelvin) in 1856, but he was unable to …   Wikipedia
