In a theoretical experiment, the six error sources led to an 37% underestimation of the diffusion coefficient. This highlights that diffusion coefficients cannot be determined accurately with existing experimental methods. At the same time, the need for measuring precise diffusion coefficients as input ...

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 when we establish a material. ...
The diffusion coefficient of Ni in stainless steel (fcc) is 1\times 10^{-22}m^{2}/sec at 500^{\circ}C and 1\times 10^{-15}m^{2}/sec at 1000^{\circ}C. Calculate the energy of activation for diffusion in Ni in this alloy over the temperature ...
Efflux ratio (ER) is defined asthe ratio of flux from the basal to apical compartment to that from apical to basal compartment in the cell monolayer. How do you calculate Papp? The Papp (1×10−5 cm·s−1) was calculated as follows:Papp = (dQ / dt) / (A x C), where dQ /...

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...
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 mobility...
Steenmann, Richter, and Licht made tensile test samples from solder with micro-additives, where the solder was heated in the cavity of the copper substrate. The substrate cavity is ground and coated with TiCN to prevent copper diffusion. The gripping parts of the tensile specimen are approximatel...
diffusion coefficients46for fully-assembled ribosomes. While these models have proven to be effective when describing small-scale/narrowly defined conformational transitions, the vast phase space associated with accommodation makes it computationally intractable to calculate the free energy. In contrast, ...
