An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is a membrane protein with an aqueous pore, meaning it allows soluble materials to travel across the ...

Very unusual atomic states are being produced: Ions are created by removing not just one but 20 to 40 electrons from each atom. These 'highly charged ions' play an important role in current research.

Solid-state batteries could be safer and more energy-dense than today’s lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult.
