The phase separation results from a competition between long-range diffusiophoretic interactions and motility and is observed at moderate activities and a wide range of packing fractions.

WebFCC actually has the most efficient atomic arrangement possible (tied with HCP). This is why we call FCC a “close-packed” structure. If you read a very old textbook, you may even see something called a “cubic close-packed” (CCP), which is another name for FCC.

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… WebThe static coefficient of friction of graphite on graphite is 0.1, (there are no units), and for graphite on graphite in a vacuum it's 0.5- 0.8. When graphite is heated up to high temperatures the coefficient of friction also …
