A Korean research team has developed a new proton exchange membrane (PEM) that significantly enhances the performance of ...

To understand the process, we need to know some terms. A semi-permeable membrane is a barrier between two areas through which some things can pass, but others cannot. A solution is a mixture ...

This is a passive process, which means it does not need energy. The oxygen diffuses across the partially permeable membrane of the alveoli cells and the capillary wall, into the red blood cells to ...

The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...
