The diamond lattice is face-centered cubic. The simplified packing fraction is 8 x (V atom) / V unit cell. After making substitutions for known volume of spheres and cubes and simplifying, the equation becomes √3 x π/16 with a solution of 0.3401. There are 14 types of lattice systems ...
Packing of atoms in the unit cell. Atoms have a different arrangement in the element which can be a simple cubic cell, body-centered cubic cell or face-centered cubic cell. Each arrangement has a different atomic packing fraction accordi...

Crystal structure determines electrochemical energy storage characteristics; this is the underlying logic of material design. To date, hundreds of electrode materials have been developed to pursue superior performance. However, it remains a great challenge to understand the fundamental structure–performance ...

15.2. Highest possible packing density of spheres, obtained by a face centred cubic array. On the other hand, a carefully selected grain size distribution can contribute to increased packing density. Adding a second fraction of non-melting particles may increase packing density considerably. The maxi...
However, recently, we have found packing in the face-centered cubic (fcc) lattice, which is easily transformed into the bcc lattice upon uniaxial stretching. In the same time, the packing regularity of the spheres in the bcc lattice was found to be enhanced for samples completely recovered ...
Mapping protein primary sequences to their three dimensional folds referred to as the 'second genetic code' remains an unsolved scientific problem. A crucial part of the problem concerns the geometrical specificity in side chain association leading to de
