Processing materials on the nanoscale, producing prototypes for microelectronics or analysing biological samples: The range of applications for finely focused ion beams is huge. Experts from the E ...
Caption: Nanosatellite thrusters that emit a stream of pure ions are the first of their kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. A stainless steel version (top) works better overall but is much more expensive to produce. MIT researchers found that a polymer version (bottom) yields comparable performance at a lower cost.
