Gas transport across hyperthin membranes.
The use of organic polymeric membranes to separate gaseous mixtures provides an attractive alternative to other methods such as selective adsorption and cryogenic distillation. The primary advantages of membrane-based separations are their relative energy efficiency and lower costs. Because the flux of a gas across a membrane is inversely proportional to the membrane's thickness, this method re...
متن کاملLipid distribution and transport across cellular membranes.
In eukaryotic cells, the membranes of different intracellular organelles have different lipid composition, and various biomembranes show an asymmetric distribution of lipid types across the membrane bilayer. Membrane lipid organization reflects a dynamic equilibrium of lipids moving across the bilayer in both directions. In this review, we summarize data supporting the role of specific membrane...
متن کاملUltrastructure and transport across epithelial membranes.
For epithelia, all too frequently this or that ultrastructure is spoken of as "absorptive" or '(secretory.'' Correlation between structure and function must relate to phenomena, such as the apparent active transport of weak electrolytes or water, that are unique for the epithelium. The macroscopic tubule of the gastric mucosa eannot sequester the active transport of hydrochloric acid from the s...

متن کاملTransport Electrons and Protons Across Membranes
Surface-active properties of ubiquinones and ubiquinols have been investigated by monomolecular-film techniques. Stable monolayers are formed at an air/water interface by the fully oxidized and reduced forms of the coenzyme; collapse pressures and hence stability of the films tend to increase with decreasing length of the isoprenoid side chain and films of the reduced coenzymes are more stable ...
