Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Atoms to product: Engineering products at the nanoscale

RATE THIS! +18
Posted in Science on 29th Aug, 2014 01:05 AM by AlexMuller

DARPA has created the Atoms to Product (A2P) program to develop enhanced technologies for assembling atomic-scale components and integrate them into materials and systems from nanoscale up to product scale, in ways that preserve and exploit distinctive nanoscale properties.

 
The new program also seeks to develop revolutionary miniaturization and assembly methods that would work at scales 100,000 times smaller than current state-of-the-art technology. Many common materials exhibit different and potentially useful characteristics when fabricated at extremely small scales, that is, at dimensions near the size of atoms, or a few ten-billionths of a meter, DARPA says.
 
These “atomic scale” or “nanoscale” properties include quantized electrical characteristics, glueless adhesion, rapid temperature changes, and tunable light absorption and scattering that, if available in human-scale products and systems, could offer potentially revolutionary defense and commercial capabilities. Two as-yet-insurmountable technical challenges, however, stand in the way: lack of knowledge of how to retain nanoscale properties in materials at larger scales, and lack of assembly capabilities for items between nanoscale (billionths of a meter) and 100 microns (millionths of a meter), slightly wider than a human hair.
 
“We want to explore new ways of putting incredibly tiny things together, with the goal of developing new miniaturization and assembly methods that would work at scales 100,000 times smaller than current state-of-the-art technology,” said John Main, DARPA program manager. “If successful, A2P could help enable creation of entirely new classes of materials that exhibit nanoscale properties at all scales. It could lead to the ability to miniaturize materials, processes and devices that can’t be miniaturized with current technology, as well as build three-dimensional products and systems at much smaller sizes.”
