Researchers in ACS Energy Letters report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power ...

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.

The traditional film model for particle dissolution assumes that flux behavior depends primarily on particle size relative to ...

Much of this exploration is taking place at the surface of our cells—the protein-packed semi-permeable membranes that act as protectors and as signaling posts to other cells in the surrounding area.

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 ...
