Cells using water-based electrolytes are usually limited to cell potentials less than about 2. 5 volts, because the very powerful oxidizing and reducing agents which would be required to produce a higher cell potential tend to react with the water.

This is an idealized situation-in practice the particles are usually always influenced by some potential, and there are many-body interactions.

Financial writer Sebastian Mallaby has said that hedge funds tend to be " small enough to fail ", since most are relatively small in terms of the assets they manage, and they usually operate with low leverage, thereby limiting the potential harm to the economic system should one of them fail.
