Osmotic pressure is the force water exerts on the semi-permeable membrane (plasma membrane) surrounding the cell. Water moves across the plasma membrane in response to an unequal distribution of ...

Osmotic energy can be generated anywhere salt ... membranes that act as a sort of "salt battery," generating electricity from pressure differences caused by the salt gradient.

272), seems only to require for its solution the relation between density and pressure for the fluid at the temperature of the experiment, when this relation for small densities becomes that of an ...
