Estuaries — where freshwater rivers meet the salty sea — are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of ...

As blood in the peritoneal capillaries comes into contact with dialysate in the peritoneal cavity, solutes in the blood diffuse into the dialysate. The osmotic gradient created by glucose in the ...

Osmotic energy, derived from salt gradients, has significant potential as a renewable energy source, although the technologies for harnessing it are still developing. One approach involves reverse ...

When a reservoir of salt water is brought into contact with a reservoir of fresh water through a special kind of semipermeable membrane, the resulting osmotic phenomena make it possible to produce ...

Ocean makes up 71% of the Earth's surface, and they also harbor one of the world's greatest yet almost untouched energy source: osmotic power. The salinity gradient where seawater and freshwater meet ...

A new membrane system turns the natural mix of seawater and freshwater into enough electricity to produce hydrogen, showing how simple salt differences could power clean fuel generation. (Nanowerk ...
