Fraunhofer IAP and TU Berlin create tetrahedral metallic effect pigments that reduce flow lines in injection-moulded plastics ...

Tetrahedral dice, which have four triangular sides, pack more densely than any other shape yet tested, according to new research. Tetrahedral dice, which have four triangular sides, pack more densely ...

The tetrahedron is the simplest of all polyhedra. Any four points in space that are not all on the same plane mark the corners of four triangles. The triangles in turn are the faces of a tetrahedron.

The original version of this story appeared in Quanta Magazine. In 360 BC, Plato envisioned the cosmos as an arrangement of five geometric shapes: flat-sided solids called polyhedra. These immediately ...

In metal-containing supramolecular complexes, organic ligands self-assemble around metal atoms to form molecular cages of various sizes and shapes. Researchers can change a complex’s shape by changing ...

Metallic effects on plastic surfaces have become standard in many industries, from automotive interiors and exteriors to toys and household appliances. However, injection-molded parts with metallic ...
