  • New Class of Ultra-Thin Polymer Films
    News - 15 Jul 2007
    They said it couldn't be done. And that's what really motivated UD polymer chemist Chris Snively and Jochen Lauterbach, professor of chemical engineering at UD. For years, polymer...
  • Sandia Develops New Type of Electrochemical Sensor
    News - 13 Jul 2007
    A Sandia National Laboratories research team is developing a new type of electrochemical sensor that uses a unique surface chemistry to reliably and accurately detects thousands of differing...
  • New Sodium Laser for Astronomers
    News - 13 Jul 2007
    A new sodium laser is giving 50 times more sky coverage to the atmospheric-correcting technology known as adaptive optics on the Keck II telescope at Mauna Kea, Hawaii. The laser lets scientists...
  • New Feat of Optical Technology for Distortion-Free Wide-Angle Images
    News - 8 Jul 2007
    South Korean researchers have designed and built an inexpensive optical lens that collects light from a large area and produces a virtually distortion-free wide-angle image. Standing in contrast to...

  • Artificial Star
    News - 5 Jul 2007
    On 28 January 2006, at 23:07 local time, a laser beam of several watts was launched from Yepun, the fourth 8.2m Unit Telescope of the Very Large Telescope, producing an artificial star, 90 km up in...
  • Wave Optics Theory of Light
    Article - 30 Aug 2007
    The behavior of light is explained by a combination of Ray Theory and Wave Theory. Historically, light was studied as rays; progress in electromagnetic theory led to the understanding of light as an...
  • Adaptive Optics Help Sharpen Night Sky
    News - 5 Jul 2007
    An artificial, laser-fed star now shines regularly over the sky of Paranal, home of ESO's Very Large Telescope, one of the world's most advanced large ground-based telescopes. This system...
  • Electrons Observed in Tunnelling Process
    News - 5 Jul 2007
    We have to climb a mountain in order to conquer it. In quantum physics there is a different way: objects can reach the opposite side of a hill simply by tunnelling through it, instead of laboriously...
