These measurements complement the previously reported results for carbon, oxygen, and iron. Assuming that the ion charge states are established by equilibration in the hot plasma at the origin of the particles, the observed mean charge states are not compatible with a single temperature. The ...
The oxygen 2 p Wannier functions display two distinct types of behavior, one type of which includes conspicuous Ag 4 d tails. Calculation of the Born effective charge tensor shows that the mean effective charges of the Ag ions differ by about a factor of 2, roughly consistent with the ...
Everything in the universe is made ofatoms, the smallest possible form of anelement. Elements include substances like oxygen, nitrogen, and carbon. Atoms are made of anucleus(a core or center) that contains particles calledprotonsand outer shells made ofelectrons. ...

a, Mobile metal ions (purple) hop (arrows) between energetically and crystallographically distinct lattice sites (triangles) with two- and six-fold coordination by oxygen ions (black). The same lattice sites are depicted schematically ind–f.b, If at timet0 = 0 (dark green) there is pe...
lie somewhere between the two extremes. Still, even in the covalent limit, there can be a 'formal charge' on one of the atoms. In the oxygen on carboxylate, for example, the nuclear charge is +6, there are six nonbonding electrons that spend all of their time in the vicinity of the...
Metrics Abstract Materials that efficiently transport and couple ionic and electronic charge are key to advancing a host of technological developments for next-generation bioelectronic, optoelectronic and energy storage devices. Here we highlight key progress in the design and study of organic mixed ionic...
For a good ionic conductor, it is necessary to have possible pathways for the diffusion of ions. With the existence of pathways, the concentration of charge carriers must be sufficient in order to achieve high ionic conductivity. For doped zirconates, it is widely accepted that the oxygen vacan...
