A team of researchers led by Margaret Murnane and Henry Kapteyn at the University of Colorado developed a sharply focused, ultraviolet or extreme-ultraviolet (EUV) light source that can be used to measure and manipulate objects at the nano-scale. Size has been a major hurdle to developing, or even seeing, the tiny components because the objects can be smaller than the waves of light illuminating them. EUV light, which has a wavelength of only tens of nanometers, can pulse in shorter bursts than any other system currently available. To create this short-wavelength light, Kapteyn and associates use a laser at visible wavelengths, and then convert the light to much shorter wavelengths using high harmonic generation (HHG)–combining photons to generate much higher-energy photons with a correspondingly shorter wavelength. Kapteyn expects the light source to be used for developing and testing EUV lithography equipment.

Imagine being able to illegally download a physical product the same way you can with music and video. The advent of desktop, home, and prosumer 3D printers is having 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.
