A Monte Carlo simulation was carried out to determine the theoretical precision of each method, considering the uncertainty of various experimental parameters. A model鈥恇ased simulation of a diffusion experiment was used to determine the theoretical accuracy as a result of six sources of error: ...
I've a question about how to define the diffusion coefficient of a certain material in CFX please? Because I want to simulate the diffusion between two liquids in a domain. I haven't found any option that we can plug into the value of diffusion coefficient ...
Nucleation the nucleation rate is relative with concentration, solubility and saturation; nuclei growth rate is relative with the diffusion coefficient of the particle, the particle surface area and particle diffusion layer thickness. For example, by reducing the temperature and increasing reactant ...
Although diffusion-weighted imaging (DWI) is useful for differential diagnosis between lung cancers and benign pulmonary nodules and masses (BPNMs), it is difficult to differentiate pulmonary abscesses from lung cancers because pulmonary abscesses show restricted diffusion. With this research we will pr...
Money can be tainted when it is associated with direct or indirect harm to others. Deciding whether to accept “dirty money” poses a dilemma because money can be used to help others, but accepting dirty money has moral costs. How people resolve the dile
Finally, we also predict the spin diffusion length (ls) of pristine CsPbBr3in the low-density limit, which sets the upper bound oflsat differentT. We use the relation\({l}_{s}=\sqrt{D{\tau }_{s}}\), whereDis diffusion coefficient obtained using the Einstein relation, with carrier mo...
The difference in the observed mobility of chloride and hydroxyl ions compared to sodium ions is related to the difference in their intrinsic or ion-specific diffusion coefficient [51] as well as charged-surface effects [52,53]. The slightly higher total chloride content and deeper ingress ...
The x-direction velocity u is calculated at the faces that are normal to the x-direction. The calculation of the diffusion coefficient and the mass flow rate at the faces of the u control volume would require an appropriate interpolation. The resulting discretization equation...
whereρis the reaction coordinateRelbow(the distance between U60 in aa-tRNA and U8 in the P-site tRNA) andDis the diffusion coefficient (estimated from explicit-solvent simulations46). While interatomic distances can provide intuitive descriptions of elbow movement, the full dynamics are multi-dimen...
(32) Remarks. The developed porous electrode model uses effective medium theory to describe the transport of ions and dissolved gas. In the simplest variant, Bruggeman's equation could be used to determine the effective ion conductivity and the diffusion coefficient, κleff = κlbulk ετ, ...
