ODYSSEY Basic Crystal Lattices|教育線上App不用買-HotApp4Game

What are the most basic lattice types encountered in the structures of elements and compounds? Is there more than one way to efficiently pack simple spheres? Why are copper and many other metals so malleable? ODYSSEY Basic Crystal Lattices helps introduce the most important cubic and hexagonal lattice types of elementary crystallography. Generic models and concrete examples are provided for the simple cubic lattice, body-centered cubic lattice, face-centered cubic lattice, hexagonally close-packed lattice, diamond lattice, and graphite lattice. Unit cells, both conventional and primitive, are shown and coordination numbers are highlighted. Custom models are provided to identify the locations of the complete sets of tetrahedral and octahedral holes. In total, one hundred models are available. Models can be inspected at any orientation and zoom level and with a choice of drawing radius for the atoms. For most models, a “clipping sphere” can be defined, highlighting the local surroundings of a selected atom and hiding the remaining structure. The distances between atoms can be measured. A glossary, comments section, and set of multiple choice questions (with randomized options) are also included.In almost no subject is three-dimensional visualization more important than in crystallography. ODYSSEY Basic Crystal Lattices complements and clarifies any textbook description of some core crystallographic concepts.
