Sentence examples for percolation level from inspiring English sources

With GNPs adding to the composite, its conductivity increases and reaches the value of σ = 10−6 Sm/m (this value is considered as percolation level) at GNPs content с in composite of φ с = 2 wt% for the composites with random filler distribution.
There are two main ingredients of this model: trap model of continuous time random walk through the meta-basins (MB) and a percolation energy level as the transition state that determines the average escape rate out of a MB.
Near-fractal clusters below or above the percolation point do not lead to anomalous diffusion.
Above a threshold, the magnitudes of storage modulus (G′) and conductivity are related to the level of percolation network as well as the intrinsic properties of the matrix and filler.

At low frequencies, complex viscosities become almost independent of the frequency as nanotubes loading being more than 1.5 wt%, suggesting an onset of solid-like behavior and hence a rheological percolation threshold at the loading level.
One of the more indisputable popular statements on crema claims that "any error in grinding or in percolation, in temperature or extraction level, is immediately denounced by the color, the texture and the persistence of the foam".
In this framework statements such as "any error in grinding or in percolation, in temperature or extraction level, has an immediate effect on denounced by the color, the texture and the persistence of the foam" or "the foam is the signature of a well-prepared espresso" can be well justified.
