Researchers from the National Institute of Standards and Technology (NIST) and the National Renewable Energy Laboratory (NREL) have reported a way to measure the amount of laser light needed to shift the electrons in a type of quantum dot between two discrete states—a low energy, ground state and a higher energy, excited state. Quantum dots may be able to serve as the ones and zeros in a quantum computer, once physicists have the ability to turn them "on" and "off". NIST's and NREL's new technique measures the dipole moment directly by enclosing the dots in a cavity, a dimming laser light pulse passing over them repeatedly. This in turn helps measure the dipole moment, indicating how easy the dots are to excite. For details, go to http://nist.gov.
Imagine being able to illegally download a physical product the same way you can with music and videos. That’s basically what’s happening with 3D printing and digital manufacturing, with huge repercussions in the intellectual property domain.
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
