Sentence examples for sharp diffusion from inspiring English sources

The profiles of the plasticizer in the glassy polymer in all samples had sharp diffusion fronts with constant volume fraction behind the front.

In this case the temporal evolution of the ellipsometric spectra is adequately described by an optical model that divides the polystyrene into a swollen layer and a non-swollen layer, separated by a sharp diffusion front, i.e. mimicking the essential characteristics of the Case II diffusion process.

The mixed region and the low-temperature phase matrix are found to have a rather sharp boundary (diffusion front), and the interdiffusion rate is estimated quantitatively from the advance of the diffusion front.

It is a glowing and flickering palette, full of deep shadow and sharp reflection, diffusion through frosted glass and submergence in menacing subterranean darkness — and Soderbergh enjoys opposing it to the cold and steady light of science.

Several numerical results on 1D and 2D test-cases of interest for flow simulation in porous media are presented, some of them exhibiting sharp contrasts in diffusion coefficients.

It permits to carry out simultaneously intensive ultrasonic, mechanical and cavitation treatments of powder materials that in turn leads to sharp acceleration of diffusion, mass-transfer processes and solid phase reactions due to crystallite size and structure changing.

But, with the use of sharp microneedles, the diffusion of the fluorescent molecule through the conduits over time seemed to deeply penetrate the epidermis and the dermis.

Non-porous beads completely eliminate intraparticle diffusion, providing sharp elution peaks with the shortest retention times.

It is shown that a very large undercooling at the interface, required for glass formation, is obtained due to the combined effects of the sharp decrease in the diffusion coefficient, or the sharp increase in viscosity of the liquid, with undercooling in this system and the large undercooling required for the attachment kinetics at the compound liquid interface in the eutectic structure.

There were some transverse grains at the layer interface and the interface between the CrN and W2N layers was not so sharp owing to atom diffusion through the interface.

We start from an energy functional accounting for bulk and surface contributions coming from both constituents of the material; the relaxed energy densities, obtained via a blow-up method, are determined by a delicate interplay between the optimization of sharp interfaces and the diffusion of microcracks.
