Ionise

In the 2000s, Nasa attempted to develop a new type of rocket using Nuclear-Electric Propulsion (NEP), which uses a nuclear reactor to generate electricity for an engine capable of producing an electromagnetic field to ionise gas to use as thrust.

Greenwood, p. 1168 When bound to a strongly electron-withdrawing metal centre, hydroxide ligands tend to ionise into oxide ligands.

The air in a region around a high-voltage conductor can break down and ionise without a catastrophic increase in current; this is called " corona discharge ".

Theremin recalled that while still in his last year of school, he had built a million-volt Tesla coil and noticed a strong glow associated with his attempts to ionise the air.
