Temperature dependence of the ionic conductivity in Li3xLa2/3−xTiO3: Arrhenius versus non-Arrhenius

Non-Arrhenius conductivity in glass: Mobility and conductivity saturation effects.

Extreme non-Arrhenius dependence of the ionic conductivity in optimized fast ion conducting glasses has been observed. When all the chemical factors controlling the ionic conductivity in glass have been optimized, the conductivity fails to reach the values expected, >0.1 (Ωcm)−1 at 298 K. A new series of glasses zAgI+(1−z) [0.525Ag2S+0.475B2S3:SiS2] have been measured for the first time and are...

A Simple Model for the Non-Arrhenius Ionic Conductivity in Superionic Glasses

Strong non-Arrhenius temperature dependence of the resistivity in the regime of traditional band transport

When a strong, though non-Arrhenius temperature dependence of electrical resistivity is observed, one usually concludes that the underlying mechanism is variable-range hopping. Unexpectedly, such observations are also made for many semiconductor systems at elevated temperatures, where a variable-range hopping mechanism seems unlikely. A satisfactory explanation for this observation is still lac...

Motor-substrate interactions in mycoplasma motility explains non-Arrhenius temperature dependence.

Mycoplasmas exhibit a novel, substrate-dependent gliding motility that is driven by approximately 400 "leg" proteins. The legs interact with the substrate and transmit the forces generated by an assembly of ATPase motors. The velocity of the cell increases linearly by nearly 10-fold over a narrow temperature range of 10-40 degrees C. This corresponds to an Arrhenius factor that decreases from a...

Protein folding kinetics exhibit an Arrhenius temperature dependence when corrected for the temperature dependence of protein stability.

The anomalous temperature dependence of protein folding has received considerable attention. Here we show that the temperature dependence of the folding of protein L becomes extremely simple when the effects of temperature on protein stability are corrected for; the logarithm of the folding rate is a linear function of 1/T on constant stability contours in the temperature-denaturant plane. This...
