Add a definition
When the bonds are in series, the selectin bond of loweractivationenergywill fail first at low loading rates (below the crossover point).
From theCambridge English Corpus
Theactivationenergywill be supposed much larger than the thermal energy.
From theCambridge English Corpus
We may consider the partially formed helix as an intermediate that gives anactivationenergyfor the helix-formation process.
From theCambridge English Corpus
The graphite moderates the neutrons belowactivationenergylevels.
From theCambridge English Corpus
A physical reason for this is that as theactivationenergyincreases, the induction time and corresponding induction length increase exponentially.
From theCambridge English Corpus
Our results suggest that as theactivationenergyis increased even further than we have shown, additional highfrequency instabilities appear.
From theCambridge English Corpus
Note that once an unstable mode is present, its growth rate changes with increasingactivationenergy, but its frequency is nearly constant.
From theCambridge English Corpus
The effect of on the rate constant thus is very small compared to the enormous increases in rate that enzymes can achieve by reducing theactivationenergy.
From theCambridge English Corpus
Semiconductor iron sulphide minerals are readily doped and would have provided an adaptable source of holes and electrons for lowactivationenergyredox chemistry.
From theCambridge English Corpus
This means that although two proteins may bind at a similar rate, if they have a differentactivationenergy, there must be two different kinetics barriers that are operative.
From theCambridge English Corpus
In contrast, the ratio of helix formation and break-up rates depends on the free energy difference between the two end configurations, and not on theactivationenergy.
From theCambridge English Corpus
Chilkoti et al. (1995) confirmed experimentally the importance of theactivationenergyin unbinding.
From theCambridge English Corpus
There also exist cases where the ignition factor is not theactivationenergy.
