Many methods and software tools have been developed to compare crystal structures. These tend to rely on structure standardization, space group and Wyckoff position identification and comparisons of crystal invariants.
When an imaginary line passing through a crystal divides the crystal into two equal portions, that crystal has a center of symmetry. Hexoctahedral crystals exhibit this feature, as do the cubic and tetrahedral classes.
Laser engraving is a permanent method of marking, etching or carving into the surface of a material such as plastic or glass. It is a popular option for logos, awards, gifts, or personal items. This technique produces a high-quality finish that is durable and easy to read.
The most common materials used for laser engraving are acrylic and metal. Both of these materials are strong and resistant to scratches, stable concerning tolerance and shrinkage, and able to withstand laser operations.
Unlike 3D printing, which requires special equipment and software, laser engraving can be performed using a standard graphics program like Adobe Illustrator or Inkscape. The software allows users to create files for the laser engraver, which is then used to etch or carve into the material being engraved. The resulting product is often quite stunning. These attention-grabbing pieces make excellent souvenirs, trophies, or recognition awards. They can also be customized to include an image or a logo.
