Fast, cheap nanomanufacturing: Tiny conical tips fabricate nanoscale devices cheaply

3 octubre 2014

Scientists have developed dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions. The technology has a range of promising applications: depositing or etching features onto nanoscale mechanical devices; spinning out nanofibers for use in water filters, body armor, and «smart» textiles; or propulsion systems for fist-sized «nanosatellites.»
