Coming Soon: Proton-Beam Chiseling
High-tech manufacturers may soon be able to use proton beams to chisel out minuscule components and circuits due to pioneering research from a Singapore institute. The proton beam is a stream of sped-up sub-atomic particles that scientists have been trying to narrow down for practical use over the last 25 years. The National University of Singapore Research Center for Nuclear Microscopy, currently holds the record for the narrowest proton beam -- which measures just 1,000th of the diameter of a human hair.
