adatom

By investigating adatom triplets of different shapes we demonstrate that the map can serve to tailor the magnetism of larger nanostructures.

"Otherwise, all the calculations show there's too high a barrier, the adatom just cannot jump by itself."

"Suddenly, almost every adatom started to move back and forth along the titanium row," said Lyubinetsky.

Half the time, that adatom is one spot over -- which makes the original appear to have moved.

The water molecule floats off, leaving behind an adatom.

The chemists determined that water can help the adatom jump a row as well: If a water molecule and an adatom are situated on either side of a raised oxygen row, a row oxygen can serve as the middleman, handing over a hydrogen from the water molecule to the adatom.

If a water molecule sits down next to an adatom, one of the water's hydrogen atoms can jump to the adatom, forming two oxygen-hydrogen pairs.

If the incoming water molecule has been stripped, the adatom appears to have hopped over.
