Visual Periodic Table Chemie vs ODYSSEY Basic Crystal Lattices使用状況と統計

What are the 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 lattice types of elementary crystallography. Generic models are provided for the simple cubic lattice, body-centered cubic lattice, face-centered cubic lattice, hexagonally close-packed lattice, diamond lattice, and graphite lattice. Conventional and primitive unit cells are shown, coordination numbers are highlighted, and tetrahedral and octahedral holes are visualized. In total more than 160 models are available, including a comprehensive set of models for all those elements that crystallize in one of the listed structure types. 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 textbook descriptions of some core crystallographic concepts.
