Study on water and oxygen transfer characteristics of HT-PEM fuel cells
Heliyon, 2023 In this study, a steady-state model is developed by combining mechanical, Navier–Stokes, Maxwell–Stefan, and Butler–Volmer equations. This model is then used to investigate the influences of diffusion layer thickness deformation under a specific assembly

Apparent Permeability Model for Shale Gas Reservoirs Considering Multiple Transport Mechanisms
Geofluids, 2018 Shale formation is featured in nanopores and much gas adsorptions. Gas flow in the shale matrix is not a singular viscous flow, but a combination of multiple mechanisms. Much work has been carried out to analyze apparent permeability of shale, but little

Effect of seasoning-layer stress on fluorine diffusion
AIP Advances, 2020 In semiconductor thin-film deposition equipment in which a fluorine- or chlorine-based gas is used as a cleaning gas, reducing residual fluorine or chlorine inside the equipment is important for increasing production efficiency and reducing production ...

The role of fluorine-containing ultra-thin layer in controlling boron thermal diffusion into silicon
Journal of Telecommunications and Information Technology, 2023 We have investigated the influence of silicon dioxide reactive ion etching (RIE) parameters on the composition of the polymer layer that is formed during this process on top of the etched layer, and finally, the role of this layer in high- temperature ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
