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 ...

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 ...

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

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 ...
