Laser Speeds Up Microfluidics by 20 Times
Jul 1, 2007 — Microfluidic systems can enable multiple rapid reactions between chemicals in fluid form. But because forces resistant to fluid flow dominate on a microscopic scale, chemicals may mix together slowly and incompletely. To increase the speed of fluid flow, researchers have used a laser to generate bubbles that burst in microseconds, driving fluid flow. Reprinted with permission of Physical Review Letters. The scientists, from the University of Twente in Enschede, the Netherlands, and from...
A Laser Cavity Close to the Size of the Diffraction Limit
Jul 1, 2007 — Researchers in Japan have developed a laser that operates at room temperature and measures only about 9 × 15 μm. Toshihiko Baba and his colleagues Kengo Nozaki and Shota Kita at Yokohama National University constructed the device by drilling...
Pushing for Change in Magnifying Lenses
Jul 1, 2007 — As scientists have realized for many years, the fluid nature and natural magnification of water could make it perfect for use in liquid lenses with an adjustable focal length. Yet prototypes developed using water and other liquids have enjoyed few...
Paper-Thin Displays Created
Jul 1, 2007 — A group at The Hong Kong University of Science and Technology has created flexible displays as thin as paper by embedding conductive wiring patterns into thermochromic composite films. The paperlike display fabricated with...
Studying a Splat in the Making
Jul 1, 2007 — The splat that droplets of plasma make when they strike a substrate is similar to the shape that pancake batter forms when it hits a hot griddle. In the past, scientists investigating plasmas have had only the splat to work with — a situation that...
Laser pulses enable rapid, localized mixing in microfluidic channels
Jul 1, 2007 — Rapid mixing of two fluids has remained a challenge within the microfluidics community. Current techniques that rely on diffusion as a mixing mechanism require mixing times up to several minutes and mixing lengths on the order of meters — making it...
A Tale of Fish and Stones
Jul 1, 2007 — For Vincent P. Palace, head of the Environmental Center for Research on Pesticides at Freshwater Institute in Winnipeg, Manitoba, Canada, success is not a fish tale. Instead, it is a fish otolith — a stonelike structure in the ear composed of...
Infrared Camera Helps Spot Perimeter Intruders
Jul 1, 2007 — Airports and harbors face a common security challenge: Their large areas translate into long perimeters — often many miles long. Traditional perimeter control has involved a fence, guards and surveillance cameras. However, fences cannot be used...
Eight Grants Awarded to Develop LED Technology
Jul 1, 2007 — Eight grants totaling more than $13 million have been awarded to develop solid-state lighting, with the goal of making it competitive with other lighting sources by 2025. The National Energy Technology Laboratory, on behalf of the US Department...
Experts Clash on Value of National Ignition Facility
Jul 1, 2007 — The National Ignition Facility (NIF) is the huge laser being built at Lawrence Livermore National Laboratory in Livermore, Calif. (see “World’s Largest Laser,” Photonics Spectra, June 2006, page 50). Its goal of “ignition” will be achieved when its...
Universal Laser Systems Secures New Plant
Jul 1, 2007 — A manufacturer of CO2 lasers and computer-controlled CO2 laser engraving, cutting and marking systems, Universal Laser Systems Inc. of Scottsdale, Ariz., has doubled the size of its headquarters by expanding into a second local operating facility....
