2. Geomembrane - Wikipedia

   en.wikipedia.org/wiki/Geomembrane

   Geomembrane. A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid (liquid or gas) migration in a human-made project, structure, or system. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the ...

3. Semipermeable membrane - Wikipedia

   en.wikipedia.org/wiki/Semipermeable_membrane

   Semipermeable membrane. Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Semipermeable membrane is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure ...

4. Peritrophic matrix - Wikipedia

   en.wikipedia.org/wiki/Peritrophic_matrix

   Peritrophic matrix. The peritrophic matrix (from the prefix peri-, meaning around, and -trophic, referring to nutrition (food)) or peritrophic membrane is a semi-permeable, non-cellular structure which surrounds the food bolus in an organism's midgut. Although they are often found in insects, [1] peritrophic matrixes are found in seven ...

5. Biological membrane - Wikipedia

   en.wikipedia.org/wiki/Biological_membrane

   A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another. Biological membranes, in the form of eukaryotic cell membranes, consist of a ...

6. Cell membrane - Wikipedia

   en.wikipedia.org/wiki/Cell_membrane

   Illustration of a eukaryotic cell membrane Comparison of a eukaryotic vs. a prokaryotic cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).

7. Peripheral membrane protein - Wikipedia

   en.wikipedia.org/wiki/Peripheral_membrane_protein

   Peripheral membrane proteins, or extrinsic membrane proteins, [1] are membrane proteins that adhere only temporarily to the biological membrane with which they are associated. These proteins attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and ...
