The addition of small atomic radius element Fe, which has large diffusion activation energy and small diffusion coefficient in Cu, could inhibit diffusion for a wide range of composition.
The NST-Ni electrode shows significant glucose sensing performance in terms of unimpeded diffusion pathways, a wide range of concentration detection, and lower limit of detection (0.186 µM) than NiO nanosheet (NS -Ni foam electrode patterNS -Niicating the efoamtivelectrodethe shapatternndent structural archindicatingf NSthei effectiveness
It is shown that the curvature of samples, caused by the diffusion stresses, is proportional to the annealing time and the difference of the intrinsic diffusion coefficients in a wide range of input parameters.
This new approximate model compares very well with the exact (numerical) solution of the general adsorption and diffusion model over a wide range of (Langmuir) isotherm nonlinearity, and pore and surface diffusivities.
In a recent publication (Moggridge, 2012), it was shown that a simple equation could be used to accurately predict the mutual diffusion coefficients in a wide range of non-ideal binary mixtures from their tracer diffusion coefficients and a thermodynamic correction factor.
Quantitative non-intrusive measurements of NO species using the Laser Induced Fluorescence technique are reported in laminar counterflow syngas air diffusion flames for a wide range of strain rates and as a function of fuel composition (i.e. H2/CO ratio).
In this review we compare and discuss macroscopic transport properties, measured using the straightforward, yet highly powerful technique "modified Ussing chambers", also denoted side-by-side diffusion cells, for a wide range of structured polymer films and composites.
Flickering diffusion flames exhibit a wide range of time-dependent, vortex-flame sheet interactions, and thus they serve as an important testing ground for assessing the applicability of chemical models derived from steady flames.
It is found that, for the adsorbing species (CO2), the model is able to well describe the diffusion anomalies over a wide range of permeation pressure, while for the weakly adsorbing species (N2), the model is inadequate to cope with the anomalies at the low end of permeation pressure.
Precipitation of calcium carbonate was carried out in the presence of poly allylamine hydrochloride), [−CH2CH(CH2NH2·HCl)−] n (PAH) (Mw 15 KDa Aldrich) using the ammonium carbonate diffusion method under a wide range of polymer and calcium concentrations.
