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.

The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
