Their findings, "First-Principles Determination of the Structure of Magnesium Borohydride," have been published in the Dec. 13 edition of Physical Review Letters. "Experimental crystal structure ...

A material's crystalline structure consists of a repeating arrangement of atoms, which can be different from material to material. That arrangement is called the crystal's "lattice type." ...

These include substrates of strontium titanate, aluminium oxide and magnesium aluminate, which have perovskite, corundum and spinel crystal structures, respectively.
