Physicists at the University of Nottingham have used advanced transmission electron microscopy (TEM) techniques to trap krypton atoms inside carbon nanotubes to form a one-dimensional gas.
Caldillo Zallo other. We report a nanoscale system consisting of endohedral fullerenes encapsulated within single-walled carbon nanotubes, capable of delivering and releasing krypton atoms on demand via coalescence of host fullerene cages under the action of an electron beam (on site) or heat (out of habitat).

Scientists have studied the behavior of atoms ever since it was hypothesized that they are the fundamental units of the universe.
The movement of atoms has a profound effect on fundamental phenomena such as temperature, pressure, fluid flow, and chemical reactions.
Traditional spectroscopy analyzes the motion of large groups of atoms and can use averaged data to describe phenomena at the atomic scale.
