A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

It’s then heated until it melts and electric current is passed through the molten salt, ripping the magnesium and chlorine ions apart. I think we need to pause a moment here to consider how *ahe ...

The cell was built with an interlayer between a tin(IV) oxide (SnO 2) electron-transporting layer and a layer made of a halide perovskite layer by coupling chlorine-bonded SnO 2 with a perovskite ...
