  2. Semipermeable membrane - Wikipedia

    en.wikipedia.org/wiki/Semipermeable_membrane

    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 , concentration , and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute.

  3. Membrane transport - Wikipedia

    en.wikipedia.org/wiki/Membrane_transport

    6] A semipermeable membrane separates two compartments of different solute concentrations: over time, the solute will diffuse until equilibrium is reached. As mentioned above, passive diffusion is a spontaneous phenomenon that increases the entropy of a system and decreases the free energy. [ 5 ]

  4. Permeability - Wikipedia

    Semipermeable membrane, a membrane which will allow certain molecules or ions to pass through it by diffusion; Vascular permeability, the movement of fluids and molecules between the vascular and extravascular compartments; Permeation of a gas or vapor through a solid substance

  5. Osmosis - Wikipedia

    en.wikipedia.org/wiki/Osmosis

    The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...

  6. Permeation - Wikipedia

    en.wikipedia.org/wiki/Permeation

    The process of permeation involves the diffusion of molecules, called the permeant, through a membrane or interface. Permeation works through diffusion; the permeant will move from high concentration to low concentration across the interface. A material can be semipermeable, with the presence of a semipermeable membrane. Only molecules or ions ...

  9. Membrane - Wikipedia

    en.wikipedia.org/wiki/Membrane

    A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles.
