To mitigate the impact of surface exchange reactions, two feasible approaches can be applied: increasing the membrane thickness and improving the kinetics of surface exchange reactions with some catalytic-active agents. It is noteworthy that according to the models that are limited by the bulk ...
the position of the real source can be used directly. Because this model ignores the heat exchange between the air mass and the environment. The calculation result must deviate from the actual situation. Generally speaking, adiabatic diffusion mode can be used for the instantaneous (within 10s) ...
19 integrated a data-driven model with a physics-based (equation-based) model for the gas exchange process of a diesel engine. The authors modelled the steady-state turbocharger using a neural network. Further, the authors integrated the data-driven model with an equation-based model. Recently...

When the hydrogenation reaction is carried out in an aqueous solvent, the H2O involved H-exchange could serve as a significant pathway, and coexists with the direct H2 dissociative hydrogenation pathway (Supplemen- tary Fig. 17)43,44. Here, the H2O solvent was replaced with D2O for ...
Magnetostatic or exchange interactions cause spin waves which are eigen disturbances in magnetic moments to propagate within magnetic materials, including ferrimagnets, ferromagnets, and antiferromagnets. It is well known that magnetostatic spin waves propagate in three distinctly different directions, depend...
