Measurements of the size and correlations between ions using an electrolytic point contact
The size of an ion affects everything from the structure of water to life itself. Here, a sub-nanometer diameter pore sputtered through a thin silicon nitride membrane is used to systematically test ion permeability by measuring the electrolytic current and current noise and show that the ions move...

The size of an ion affects everything from the structure of water to life itself. Here, a sub-nanometer diameter pore sputtered through a thin silicon nitride membrane is used to systematically test ion permeability by measuring the electrolytic current and current noise and show that the ions move with a grossly distorted hydration shell in a correlated way. |
