Researchers from the University of Southamp- ton, U.K., Italian Institute of Technology, and the University of Magna Graecia, Italy, presents
in Physical Review Letters their work with carbon nanotubes in a photonic metamaterial. Hybridiza- tion of single-walled carbon nanotubes with plas- monic metamaterials leads to photonic media with an exceptionally strong ultrafast nonlinearity. This behavior is underpinned by strong coupling of the nanotube excitonic response to the weakly radiating Fano-type resonant plasmonic modes that can be tailored by metamaterial design. © Physical Review Letters

known, simple methods. The components can also be used for magnetic refrigerators, cleaning exhaust gases and much else besides.
The figure shows examples of the different types of ceramic components that Risø wants to manufacture in one go using well-known, simple methods such as tape casting and extrusion. The component on the left and far right could be an oxygen membrane. The two compo- nents at the centre could be components for magnetic refrigeration. Here, one end must function in the cold while the other end needs to function in the heat to pump the heat out of our refrigerators. © Risø National Laboratory for Sustainable Energy
