While significant breakthroughs on nanozymes have been made in recent years, the field still faces several challenges that need to be addressed. (1) Efficient synthesis of nanozymes Although more than thousands of nanozymes have been developed, the current methods for their design and synthesis often...
The hexahedron (cube) has four faces. The octahedron has five faces. The dodecahedron has 12 faces. The icosahedron has 20 faces. All platonic solids are regular, meaning they have equal sides and angles, and each one has an equal amount of sides meeting at every vertex. Each polygonal sid...

consists of a 5-sided pentagon, and is a separate piece. Each face contains magnets which allow the various faces to stick together. Amazingly, when a bunch of these faces are all thrown into a container and jumbled together, they eventually assemble themselves into complete dodecahedrons. ...
