What Do Membranes Do? Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small ...

Mixtures of oil and water can be efficiently separated by pumping them into thin channels between semipermeable membranes, paving the way to cheaper and cleaner ways to deal with industrial waste.

which is a water separation and decontamination process that uses pressure to force water through a semi-permeable membrane. ...

This fascinating chemical reaction demonstrates acid-base interactions and shows how membranes can be semi-permeable, allowing water to pass through and causing the egg to change size. See this ...

The heart of the bioreactor is the hollow fiber module. It is composed of straw-like semipermeable membranes with a high surface/volume ratio. These semipermeable membranes form a two-compartment ...

Speaker one: Osmosis is the diffusion of water molecules across a semi-permeable membrane, from a higher water concentration, to a lower water concentration. Speaker two: Water uptake in plants ...
