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.

In an osmotic process, water flows from a solution with a lower solute concentration (for example, fresh water) through a semipermeable membrane into a solution with a higher solute concentration ...

The new approach involves the use of two semipermeable membranes, one hydrophilic, the other hydrophobic, with a channel between them whose size can vary from 4 to 125 millimeters. An oil and ...

Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times ...

In either case, processing cost is magnified. One promising solution is the semipermeable membrane (SPM), a thin, flexible film or fabric typically made from polytetrafluoroethylene (PTFE) or ...

It involves using a very large semipermeable membrane to allow a solvent, such as fresh river water, to flow into a more concentrated and pressurized solution, such as sea water. Salt molecules ...

This semi-permeable membrane has a pore size of around 0.0001 microns, effectively only allowing the small water molecules through and catching any larger molecules of contaminants, organic ...

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 density ...
