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 ...

There are two dissolved oxygen meters in the engineering laboratories. The Orion VersaStar DO meter uses a polarographic probe to determine DO. As DO passes through the semipermeable membrane, a ...

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 ...
