The oxygen evolution reaction (OER) is a key process in electrochemical energy conversion devices. Understanding the origins of the lattice oxygen oxidation mechanism is crucial because OER catalysts operating via this mechanism could bypass certain limitations associated with those operating by the convent...

In the structure drawn, all of the particles (yellow) are the same. In this particular case, the lattice points defining the unit cell coincide with the centers of the crystal's particles. This need not always be the case. The Ionic Lattice ...
(Elements or compounds that crystallize with the same structure are said to be isomorphous.)Many other metals, such as aluminum, copper, and lead, crystallize in an arrangement that has a cubic unit cell with atoms at all of the corners and at the centers of each face, as illustrated in...
Hydrogen zeolites of different structure and chemical composition have been prepared and their lattice OH vibrations determined by high-resolution infrared spectroscopy. The frequency of all the lattice OH groups in these zeolites has been rationalized in terms of two concepts: (i) the frequency of ...

Molecular structure determination in crystals depends on the presence of the crystal lattice. In liquids, there is no underlying lattice, so phase relationships between scattered X-rays or neutrons are not preserved. Hence, only pair-distance distributions can be obtained from simple diffraction experim...
