Dialysis and concentration of protein solutions.
Andrew SM, Titus JA, Zumstein L. Andrew SM, et al. Curr Protoc Toxicol. 2002 Feb;Appendix 3:A.3H.1-5. doi: 10.1002/0471140856.txa03hs10. Curr Protoc Toxicol. 2002. PMID: 20976673
Conventional dialysis separates small molecules from large molecules by allowing diffusion of only the small molecules through selectively permeable membranes. Dialysis is usually used to change the salt (small-molecule) composition of a macromolecule-containing solution. …

The Permeability of Vacuum and the Revised International System of Units.
Goldfarb RB. Goldfarb RB. IEEE Magn Lett. 2017;8:1110003. doi: 10.1109/LMAG.2017.2777782. Epub 2017 Dec 29. IEEE Magn Lett. 2017. PMID: 29682220 Free PMC article.
The revised SI will include a redefinition of the ampere. One consequence is that the permeability of vacuum will not have a fixed numerical value but will become, in principle, a measurable quantity. ...However, its expression in the centimeter-gram-second system o …

Out-Of-Plane Permeability Evaluation of Carbon Fiber Preforms by Ultrasonic Wave Propagation.
Lionetto F, Montagna F, Maffezzoli A. Lionetto F, et al. Materials (Basel). 2020 Jun 12;13(12):2684. doi: 10.3390/ma13122684. Materials (Basel). 2020. PMID: 32545522 Free PMC article.
The ultrasonic data were used to calculate unsaturated out-of-plane permeability using Darcy's law. The permeability results were compared with saturated out-of-plane permeability, determined by a traditional gravimetric method, and validated by some analytic …
