Sentence examples for difficult diffusion from inspiring English sources

The difficult diffusion of HDL into tissues from blood suggests the stable presence of LE at the administration site, while ED might be deactivated by its relatively rapid chemical hydrolysis and hydrolase activity of HSA, in the interstitial fluid of the administration tissue.

The two-stage increase in Ge concentration can be explained by the more difficult diffusion of Ge atoms into the Si substrate than that of Si atoms into the Ge layer.

In such cases the viscosity of the medium is relevant; the more viscous, or "thick," the medium, the more difficult the diffusion and the slower the reaction.

The shrinking results in a decrease of the average pores size that makes more difficult the diffusion of Orange II.

The presence of vigorous, anti-parallel flow streams along the longest dimension of the animal suggests a fairly well organized flow circuit across distances that are prohibitively difficult for diffusion to traverse.

In ethylene-based copolymers, large comonomers/branches make the sliding diffusion difficult in the crystalline regions constituted by small monomers.

Unsuccessful catalysts were found to have either nearly zero carbon solubility, or to form numerous intermediate carbides, making it difficult for the diffusion required for graphite precipitation to occur.

Therefore, denser beads would be less porous, and it would be more difficult for substrate diffusion to go through the beads.

Following the same ideas, and in order to avoid that the transition length between the maximum and minimum coefficient values varies with the gradient threshold, which makes controlling diffusion difficult, we proposed in [44] the local variance controlled forward-and-backward diffusion (LVCFABD) coefficient: (11).

The likely explanation for this fact is that the long exposure time associated with the reduced irradiance in the first period of the activation increased the conversion at the superior layers and turned difficult the light diffusion within this 2 mm layer, reducing the conversion/KHN at 3 mm.

Concluding, we find that domain fusion is a tool to superannuate the random diffusive interaction of a domain pair by embedding them in an architecture which ensures their interactions that would be difficult by random diffusion in a cell alone.
