Cardillo-Zallo et al. report on a nanoscale system consisting of endohedral fullerenes encapsulated within single-walled carbon nanotubes, capable of the delivery and release of krypton atoms on-demand, via coalescence of host fullerene cages under the action of the electron beam (in situ) or heat (ex situ).

Square ice between two graphene sheets as seen in a transmission electron microscope (TEM); high-contrast dark spots are oxygen atoms that indicate positions of water molecules; hydrogen atoms yield too little contrast to be resolved even by the TEM. The top right inset shows a magnified image of a small area in the centre of the ice crystal. Image credit: University of Ulm.
