However, for a static sample at 1550 °C and under 15 min, the experimental data appear to be reasonably well explained by pure molecular diffusion; therefore, the presented value of diffusivity D=3⋅10−11m2/s is noteworthy. For the natural convection, a Sherwood correlation for the ...
The diffusion coefficient of the sample KTM3 was found to be higher than KT3. This is most probably the reason for the increase in photovoltaic efficiencies of the DSSCs. This increment can be recognized due to the larger number of the diffusion coefficient of triiodide rendering the dye ...
The intra-particle diffusion (IPD) model was used to determine the adsorption mechanism through three stages. The first stage means the external mass transfer of the metal ions from the solution to the adsorbent surface through the boundary layer (film diffusion). The second stage depends on the...
liquid Pb-rich matrix of near eutectic composition, it was shown that an excellent estimate of the effective interface diffusion coefficient is given by the equation () D~I ¼ 2 D~c0 D~c D~c þ D~c0 ; ½18 where D~c0 is the chemical diffusion coefficient in the c¢ phase...
D is the diffusion coefficient of the drug in the matrix, A is total amount of drug in the unit volume of matrix, Csis the solubility of a drug in a matrix, ε is porosity of matrix, γ is tortuosity of the matrix t is time in hours. ...
diffusion coefficientA new formula has been developed to estimate diffusion coefficients for a binary system for some gases dependent on temperature, pressure, molecular weight, and a Pitzer acentric factor in a different range of temperatures. In this work, an introduction of the available observed ...
The interaction between the diffusing, sorbed, species is taken into account by the introduction of an interchange coefficient ij, which is estimated using a logarithmic interpolation formula. To verify the developed Maxwell–Stefan formulation, we have carried out kinetic Monte Carlo (KMC) simulations...
Compared with pure CaCO3, the energy storage power density or decomposition rate is improved by 120% due to lower activation energy and promotion of Ca2+ diffusion by binary sulfate. The energy release or carbonation rate rises by 10% because of high O2− transport ability of molten binary ...
This maximum value is determined with the formula: M=2N−1 where M is the maximum decimal value and N is the number of bits in the word. For example, what is the largest decimal number that can be represented by 4 bits? M=2N−1=16−1=15 With 4 bits, the maximum possible ...
