Program seeks ability to assemble atom-sized pieces into practical products
Washington DC (SPX) Dec 30, 2015
DARPA recently launched its Atoms to Product (A2P) program, with the goal of developing technologies and processes to assemble nanometer-scale pieces-whose dimensions are near the size of atoms-into systems, components, or materials that are at least millimeter-scale in size. At the heart of that goal was a frustrating reality: Many common materials, when fabricated at nanometer-scale, exhibit unique and attractive "atomic-scale" behaviors including quantized current-voltage behavior, dramatically ... read more

				Heat radiates 10,000 times faster at the nanoscale When heat travels between two objects that aren't touching, it flows differently at the smallest scales - distances on the order of the diameter of DNA, or 1/50,000 of a human hair. While rese ... more		Shaking the nanomaterials out Purifying water and greening nanotechnology could be as simple as shaking a vial of water and oil. At least that's the case for a new method to clean contaminated water full of unwanted nanomaterial ... more
