Their technique will be to copy how DNA self-assemblies into an intertwined structure.
The second step will be to assemble those micro-scale subassemblies into millimeter-sized products that continue to maintain the quantum effects, as well as the lower melting points and higher specific heats of nanoscale assemblies. That step will take 12 months of the 3-year program. Our first milestone will be to assemble two types of sub-200 nanometer gratings into 210 micron assemblies that maintain their nanoscale properties.” “We assemble layer-upon-layer of spherical diffraction gratings. “We have already shown we can assemble two types of nanoparticles for the control of infrared light,” said Gross. HRl has subcontracted with Intelligent Materials Solutions (Princeton, New Jersey) to extend the nanoscale magic of advanced materials by precisely assembling them atom-per-atom. One of the leading contractors, HRL Laboratories, LLC (Malibu, Calif.), spoke about the program to EE Times last October, before DARPA was ready to go public with some aspects of the program.

The challenge is how to retain the characteristics of materials at the atomic scale in much larger ‘product-scale’ (typically a few centimeters) devices and systems.” “These ‘atomic-scale’ behaviors have potentially important defense applications,” says DARPA’s Atoms to Products website, “including quantized current-voltage behavior, dramatically lower melting points and significantly higher specific heats, for example. The agency has now set that challenge to 10 laboratories nationwide in its Atoms to Products program. The Defense Advanced Research Project Agency (DARPA) is looking for a way to capture the benefits of both worlds: the nanoscale manufacturing while upsizing to a more practical millimeter scale. PORTLAND, Ore.-Materials have uncommon electrical and quantum-level properties at the nanoscale that disappear at the millimeter-scale, where most chips are manufactured.
