Electrochemical reactions drive shape change in new nanoarchitected metamaterial. A newly developed type of architected metamaterial has the ability to change shape in a tunable fashion. While most ...

Anisotropic nanoparticles are nanoparticles that possess different properties along different axes. Unlike their isotropic counterparts, which have uniform properties in all directions, anisotropic ...

Researchers have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...
