Transmission electron microscope (TEM). View of a laboratory with a TEM (right) and its control panel (left). This particular TEM is used to micro-engrave an aluminium fluoride target. The electron beam of the microscope may be focused to make holes just 2 nanometres (billionths of a metre) in diameter. This would allow all 29 volumes of the Encyclopaedia Britannica to be engraved on a target a couple of millimetres wide. More important uses of the technology could include ultra-fast nanometre-scale electronic circuits,micro-robotics and tailor-made molecular sieves.
