MIT researchers have run ionic thruster experiments and found they may be a far more efficient source of propulsion than conventional jet engines. In their experiments, they found that ionic wind ...

Scientists fill 'historical gap in textbooks' to resolve the crystal structure of this simple yet elusive mineral ...

Listen to the full series on BBC Sounds. Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. See the study guide on the three states of matter to ...
