Sentence examples for gas diffusion rate from inspiring English sources

The ammonia gas diffusion rate is a function of the water content in the sediment.

In addition, the unique structure of DP-Co3O4 with pore-rich and high catalytic activity endows fast gas diffusion rate and high sensitivity at room temperature.

The porosity of the surface of thin films directly influences the gas diffusion rate and chemisorption of oxygen and analyte gas so as to enhance the gas sensing properties [61].

It was found that addition of uncatalyzed carbon black (u-CB) into the cathode catalyst layer enhanced the performance at high current density region, due to an increase in the gas diffusion rate.

By controlling the SDC content, as well as the thickness and porosity of the catalyst layer, the gas diffusion rate and the conduction networks for electrons and oxide ions were optimized, resulting in a marked reduction of the overpotential.

According to Fick's first law of diffusion, if the matrix is assumed as sphere, the gas diffusion rate of shale matrix per unit time and per unit volume can be expressed as follows: frac{partial V}{partial t} = frac{{6Dpi^{2} }}{{R^{2} }}left[ {V_{text{E}} left( {psi_{text{f}} } right) - V} right] (4).

The results are discussed based on calculated gas diffusion rates for different possible reaction pathways.

In the film series investigated, one could observe that the lowest gas permeability and solubility coefficient values and the highest gas diffusion rates were obtained before the Soxhlet extraction step.

A proper operating temperature of the sensors is necessary to achieve a balance between the interaction of test gas molecules on the surface of the oxide and the test gas diffusion rates during the gas-sensing test, and to obtain an optimal gas response.

The difference in gas diffusion rates between these habitats could contribute the presence or absence of genes for nitrogen fixation in the species that we analysed.

We speculate that it might be related with multiple factors, for example, the substrate surface roughness, nucleation density, and gas molecular diffusion rate.
