The thickness of the diffusion barrier in some applications like CC are usually between 150 and 300 nm [37]; so {001}<100> STO films obtained in this work with a thickness of 800 nm are expected to be excellent diffusion barrier.
Metabolic rate can be expected to be low as diffusion is slowed down and enzymes are unable to make the conformational changes that are characteristic of their activity.
As noted above, reactive oxygen species generated by electron hole recombination mechanisms at the titania surface were expected to be capable of diffusion through the gas-phase, and an AFM probe represents an even less well-confined excitation source than an aperture.
Nevertheless, the discharge capacities of Li1.4Mn4/6Ni1/6Co1/6O2.45 and Li1.5Mn4/6Ni1/6Co1/6O2.5 electrode in the first three cycles gradually rise as cycles continuing, which is expected to be that Li ions diffusion paths are not fully opened.
Considering the results of the fDTI experiment the signal contrast between stimulus and rest conditions was expected to be maximal when the diffusion gradient direction is perpendicular to the tract.
Altogether this may suggest an increase in interstitial K+, but serum K+ levels may not correlate with interstitial K+ levels (Clausen, 2013a) and increased interstitial K+ would be expected to be rapidly removed by diffusion and through the capillary network of blood vessels.
This might limit their ability to reach the bacteria since the diffusion constant of a 0.5-µm droplet is expected to be much lower than the diffusion constant of a free histone.
Therefore, Ir is expected to be applicable for the oxygen diffusion barrier (ODB), which is the most important part of ultrahigh-temperature coatings.
Since the general mechanism of Ag- and Au-catalyzed MACE of Si is similar [11, 33, 35], the findings of this study may also apply to porous SiNWs fabricated with Au metal catalyst, except that metal ion-induced etching is expected to be greatly suppressed and hole diffusion acts as the main mechanism of porosification and tip etching.
As mentioned earlier, when using liquid phantoms with Intralipid particles to provide Brownian motion, the effective Brownian diffusion coefficient (flow index) measured by DCS is expected to be equivalent to the conventional Brownian diffusion coefficient predicted by Einstein [ 52].
However, as a simple cdr2p concentration gradient in the cytoplasm is expected to be very shallow (due to rapid diffusion), it is likely that additional layers of regulation such as through phosphorylation states or diffusion barriers would be needed to generate suitably steep gradients.
