occupying the octahedral holes. Notice that the octahedral holes are along the edges (for a net of three cations) and in the center of the cube (one more cation). Thus we have four anions (FCC) and ...

Protein crystallography has had a roller coaster ride since the structure of myoglobin was revealed approaching 40 years ago. One result is that we may already have collected structures for a major ...

Switching the growth mode of inorganic crystals layer-by-layer has been a longstanding goal in materials science, inspired by the extraordinary natural nanocomposites comprising the biominerals found ...

For a photonic crystal (PhC) of finite size, it is important to calculate its transmission and reflection spectra. For two-dimensional (2-D) PhCs composed of a square lattice of circular cylinders, ...

A low-magnification plan-view HAADF images of a two-unit-cell freestanding STO film transferred to a holey carbon TEM grid. (Credit: Nature) Regular readers of Physics World will already be familiar ...

The monoclinic structure has two unit cells. The primative cell (P) has fractional lattice points at the corners of the cell, and the base-centered cell (C) has additional fractional lattice points at ...
