Iron 'Veins' Are Secret of Promising New Hydrogen Storage Material

Caption

Particles of pure magnesium (left) can only collect a limited amount of hydrogen on their outer surfaces, and the process is slow. But when the magnesium is doped with iron (right), far more hydrogen is delivered through the iron layers, which also results in much faster charging.
