membránov

Membránov is a term that can refer to several things, primarily in the context of biology and technology. In biology, a membrane is a thin, flexible sheet that covers, lines, or separates parts of an organism. The most common example is the cell membrane, which encloses the cytoplasm of a cell and regulates the passage of substances into and out of the cell. Cell membranes are composed of a lipid bilayer with embedded proteins. Other biological membranes include nuclear membranes, which surround the nucleus, and organelle membranes, which compartmentalize specific functions within eukaryotic cells.

In a broader technological sense, a membrane is a permeable barrier that allows the separation of certain components from a fluid mixture. This principle is utilized in various separation processes. For instance, in water purification, reverse osmosis membranes are used to remove dissolved salts and other impurities from water. Dialysis membranes are employed in medical treatments to filter waste products from the blood of patients with kidney failure. Membrane filtration encompasses a range of techniques, including microfiltration, ultrafiltration, and nanofiltration, each with different pore sizes and applications in industries such as food and beverage, pharmaceuticals, and chemical processing. The development and optimization of membrane materials and their manufacturing processes are ongoing areas of research and engineering.
