A new technique for printing extraordinarily thin lines quickly over
wide areas could lead to larger, less expensive and more versatile
electronic displays as well new medical devices, sensors and other
technologies.


Solving a fundamental and long-standing quandary, chemical
engineers at Princeton developed a method for shooting stable jets of
electrically charged liquids from a wide nozzle. The technique, which
produced lines just 100 nanometers wide (about one ten-thousandth of a
millimeter), offers at least 10 times better resolution than ink-jet
printing and far more speed and ease than conventional nanotechnology.
