Sentence examples for diffusion of heavy from inspiring English sources

The test results showed the concentrations of heavy metals which leached from the bottom ash in porous concrete were below the selected criteria, and the characteristics of geopolymer dominantly affect the diffusion of heavy metals from bottom ash.

The transient one-dimensional diffusion of heavy ions in a plastic container filled with the gel was imaged nondestructively by the X-ray CT scanner with an in-plane resolution of 0.31 mm and slice thickness of 2 mm.

It is shown that the validity of this restriction is based upon the combination of an optimistic selection of the parameters governing the surface diffusion of heavy atoms and, more importantly, upon an erroneous application of results from the theory of random walks on regular lattices.

The experimental results showed that the restrictive diffusion of heavy oil molecules is affected by the joint functions of several factors, such as the operating conditions, the size and configuration of the reactant molecules, and the average pore diameter of the catalyst.

So it was very important to understand diffusion mechanism of the heavy gas diluted by water curtain and explore pattern of the effect of water curtain's setting parameter on the diffusion capacity of heavy gas diluted with water curtain.

Medical X-ray computed tomography (CT) was applied to the measurement of the diffusion coefficients of heavy ions in an artificial barrier material for the disposal of nuclear wastes.

An example of the beam-induced diffusion of a heavy Ce atom is shown in Fig. 17.

This new catalyst is composed of matrix and zeolites with stepwise porosity and acidity that allow stepwise diffusion and cracking of heavy molecules while minimizing coke formation.

A variety of export systems that enlist members of three protein families assure ion efflux: The RND (for Resistance, Nodulation, cell Division) family of permeases [74], the CDF (for Cation Diffusion Factor) family of heavy metal transporters [89], [90], and the P-type ATPase family of ion pumps [91].

It is proposed that the low diffusivity of such heavy elements retards these diffusion-controlled phase transformations (feathery and lamellar) so that the massive transformation, which does not require diffusion, but which occurs at a lower temperature can take place.

An intramembrane diffusion model was used to describe kinetics of heavy metal sorption by these hydrogels and the calculated apparent diffusion coefficients were 2 3 times larger than in commercial ion-exchange resins.
