ARLINGTON, Virginia. DARPA officials are looking to develop technologies and processes to build nanometer-scale pieces whose dimensions are near the size of atoms—into systems, components, or materials that are at least millimeter-scale in size. The big hurdle to this goal is that many common materials, when fabricated at nanometer-scale, exhibit unique and attractive “atomic-scale” behaviors but lose them when they are built at product scale dimensions such as a few centimeters. So DARPA launched the Atoms to Product (A2P) program and chose ten groups to go and solve this challenge.
