Physicists have turned a long-standing imaging workhorse into a kind of nanoscale chisel, using a razor-precise ion beam to ...
In recent decades, the preparation of samples for transmission electron microscopes has transformed, thanks to the introduction of focused ion beam (FIB) instruments. Known as either single-beam or ...
The "tractor beam" approaches depend on precise shaping of the intensities of laser beams US space agency Nasa has funded a study of "tractor beams" to gather samples for analysis in future missions.
