Hence, his claim that the face-centered cubic lattice is the most efficient arrangement became known as the Kepler conjecture.
12.
The cubic lattice is therefore said to be self-dual, having the same symmetry in reciprocal space as in real space.
13.
This face-centered cubic lattice.
14.
Each central sphere can have up to twelve neighbors, and in a face-centered cubic lattice these take the positions of a cuboctahedron's vertices.
15.
However, at pressures in excess of 1 Mbar it is predicted that the structure would shift to a more stable face-centered cubic lattice.
16.
Kepler experimented and could not find any more efficient arrangement than the so-called face-centered cubic lattice, which has a packing efficiency of 74 percent.
17.
Schoen named this surface'primitive'because it has two interwined congruent labyrinths, each with the shape of an inflated tubular version of the simple cubic lattice.
18.
The primitive cubic lattice of iodide ions bridge by I 2 molecules, present in [ Cp * 2 Fe ] 4 [ I 26]
19.
For example, NaCl can be described as close-packed chloride ions ( in a face-centered cubic lattice ) with sodium ions in the octahedral holes.
20.
Kainosite, is part of the orthorhombic crystal class minerals, which is a system that results from stretching a cubic lattice along two of its orthogonal pairs.
