A research team lead by Professor Martin Wegener at the Karlsruhe Institute of Technology has succeeded in realizing a new material class through the manufacturing of a stable crystalline metafluid, a pentamode metamaterial. Using new nanostructuring methods, these materials can now be realized for the first time with any conceivable mechanical properties. The researchers will present their results in the cover story of the May issue of Applied Physics Letters.
