FCC vs. HCP

Properties in Nanoscale
Category General
Difficulty Level Normal
Audience Level General
Description Have a good knowledge of material structures leads to recognizing material behavior based on its structure. In this course, material structures and properties are elaborated in bulk and nanoscale.
Overview
It is clear that, every atomic structure has its own specific bulk properties. Therefore, being familiar with atomic arrangements, different atomic bonds and different kinds of cubic structures provide a general understanding for recognizing materials and components’ properties. On the other hand, in nanoscales, atomic structures are changed which generates novel properties.
Hence, being familiar with mentioned different parameters in atomic structure makes what happens in nanoscale understandable.

Booklet
Description
 It compares FCC and HCP lattices, the relation between coordination number and packing factor, and the independency of atomic packing factor from the number of existing atoms in the structure and unit cell.
Mental Challenge
 If FCC and HCP are both close packed, what is the difference between them?
Quizzes and Activities

Activity: Research the differences between macroscopic properties of HCP vs FCC.
