Web1 day ago · The permeation time for the SH-LTA (250 ns) was much shorter than that for intact-LTA (400 ns) as depicted in Fig. 10 b, which was entirely due to the dramatic difference in pressure as shown in Fig. 10 c. During the first cycle (0–150 ns), the local pressure in the inlet area decreased sharply for SH-LTA due to the vacuum space created …

WebPermeation is the process of molecular penetration of gases, vapours or fluids through the material membrane of a solid. Permeation rates are inversely proportional to the subsurface concentration. These are, in turn, affected by the thickness of the membrane, the intrinsic permeability and mass diffusivity of the material.
