The inherent strength of carbon nanotubes has made them candidate materials for reinforcing composites. It is also possible to put a second material into the core of a nanotube for electronic applications or for use as contrast agents. Sun et al. (p. 1199; see the Perspective by Wang and Zhao) exploit both these properties and use carbon nanotubes as state-of-the-art high-pressure chambers that allow in situ observations of pressure-induced processes at atomic scale. Defects induced on the surface of the nanotubes moved and coalesced, which caused the tubes to contract and squeeze out metal particles that had been trapped inside.
