Crystallization-induced formation of rigid amorphous fraction

In crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres. The radius of the spheres is taken to be the maximum value such that the atoms do not overlap. For one-component crystals (those that contain only o… Web6 hours ago · Crystal Palace would have been safe in the Premier League under Patrick Vieira, according to former striker Chris Sutton.
