Crystal Systems and Bravig
The crystal system is divided into seven basic categories according to the macroscopic symmetry of the crystal (such as rotation axis, mirror, inversion center, etc.), which is used to describe the symmetry characteristics of the crystal structure. Bravig is a mathematical model describing the translational symmetry of crystals, proposed by French scientist Auguste Bravie, a total of 14 possible lattice types, divided into seven subclasses under the crystal system. The classification of crystal systems is based on the macroscopic symmetry operation of crystals.
Spiral arranged nanowires (microscopic 3D schematic diagram)
Spiral arranged nanowires are a type of nanomaterial with a helical structure, typically formed by self-assembly or guided growth of one-dimensional nanowires. This structure has important applications in materials science and nanotechnology.
Cubic porous skeleton
A cubic porous skeleton is a structure with a cubic shape and containing a large number of pores. This structure has wide applications in materials science and biotechnology, especially in fields such as bone scaffolds and gas storage.
