The unit cell of the layered perovskite structure of strontium ruthenate. Ruthenium ions are red, strontium ions are blue, and oxygen ions are green. ... SRO displays ...
Single-room occupancy (SRO) is a type of low-cost housing typically aimed at residents with low or minimal incomes, or single adults who like a minimalist lifestyle, who rent small, furnished single rooms with a bed, chair, and sometimes a small desk. [1]
A primitive cell is a unit cell that contains exactly one lattice point. For unit cells generally, lattice points that are shared by n cells are counted as 1 / n of the lattice points contained in each of those cells; so for example a primitive unit cell in three dimensions which has lattice points only at its eight vertices is considered to contain 1 / 8 of each of them.

The diagram to the right shows edges for an equivalent unit cell with A in the cube corner position, B at the body center, and X at face-centered positions. Four general categories of cation-pairing are possible: A + B 2+ X − 3, or 1:2 perovskites; [8] A 2+ B 4+ X 2− 3, or 2:4 perovskites; A 3+ B 3+ X 2− 3, or 3:3 perovskites; and A + B 5 ...
Strontium titanate's mixed conductivity has attracted attention for use in solid oxide fuel cells (SOFCs). It demonstrates both electronic and ionic conductivity which is useful for SOFC electrodes because there is an exchange of gas and oxygen ions in the material and electrons on both sides of the cell.

Like the conductivity in LaAlO 3 /SrTiO 3, the magnetism only appeared when the LaAlO 3 films were thicker than a few unit cells. [30] However, unlike conductivity, magnetism was seen at SrO-terminated surfaces as well as TiO 2 -terminated surfaces.
The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. [2] The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ). The positions of particles inside the unit cell ...
