The art of packing elongated pentagonal bipyramids

Researchers have synthesized crystals of elongated gold bipyramids and have described their optimal packing in three-dimensional assemblies. This result, at the crossroads of chemistry and geometry, offers prospects for the …

Singular currents in graphene

Amongst the many extraordinary properties of graphene, its giant diamagnetic response at zero doping, predicted in the 1950s, had to this day not been measured directly. By controlling the doping …
