• Smallest silicon particles light way for new sensors, materials
  Researchers at Purdue University (West Lafayette, IN) have discovered how to harness the light-emitting properties of porous silicon to stabilize the material's surface and direct it to respond to specific chemical environments or cues.
• NIST standard to help satellite correctly see the light
  A small glass disk designed and manufactured by the National Institute of Standards and Technology soon will be orbiting the Earth aboard a satellite that will provide unusually detailed data about the chemical composition and properties of the planet.
• Los Alamos researchers take a new thin-film deposition method for a spin
  The new technique works by spinning the substrate material on a turntable-type apparatus at up to 7000 rpm. Once the substrate is spinning, a technician adds a small portion of a polymer to the center of the substrate. The polymer quickly spreads from the center to the edges of the substrate material, producing a quality coating in only a fraction of a second.
• Nebraska team 1st to observe Kapitza-Dirac effect
  The luminous green lasers in Herman Batelaan's laboratory at the University of Nebraska-Lincoln (Lincoln, Nebraska) are more than just pretty. They are the critical element in Batelaan's team becoming the first to observe the Kapitza-Dirac effect, an accomplishment that could make possible measuring devices that are thousands of times more accurate than those in use today.
• New electronic paper technology promises more colorful, versatile displays
  A man in a cafe slips on his glasses and opens his newspaper, but instead of headlines and halftone pictures, he's treated to animations, web pages, and video. As futuristic as it sounds, researchers at the University of Rochester and elsewhere are racing to develop a technology that would not only make flexible, paper-like video displays a reality, but also make them full color.
• People-counting thermal camera never lies
  Speaking at the Institute of Physics conference on sensors and their applications, which ran this week in London, Steve Hollock from IRISYS described a sensor developed by the firm that could bridge the gap between accurate but expensive thermal imagers with 50,000 pixels and the simple, cheap infrared-beam sensors that are too primitive for many desired applications.
• Laser technique examines movement in nucleus of living cell
  By colliding two laser beams head-on, scientists at the University of Illinois (Champaign, IL) can measure the movement of chromatin (tiny packets of DNA) in the nucleus of a living cell. Understanding how chromatin motility affects reactions, like the transcription of DNA into RNA for the production of proteins, is essential to extending our knowledge in such areas as cell reproduction, embryology and genetic engineering.
• Sandia develops nanotemplates for nanostructures
  The first vision of a peaceable kingdom in which deposited atoms form orderly, controllable 2-D nanopatterns has been observed by researchers at the Department of Energy's Sandia National Laboratories (Albuquerque, NM). Pattern control at this level means that it may be possible to form nanotemplates to fine-tune the device characteristics of self-assembling nanostructures.
• Sandia's Z-Beamlet laser confirms even pellet compression
  In its first try as a diagnostic tool, the third-biggest laser on earth, Z-Beamlet at Sandia National Laboratories, confirmed that the lab's Z machine – the most powerful laboratory producer of X-rays in the world – spherically compressed a simulated fusion pellet during a firing, or shot, of the giant accelerator.
• MEDICAL LASER REPORT:
  Tracking images laser coagulation
  Laser coagulation is a thermal technique that has found use in prostate, GI, and eye surgeries. Ideally the surgeon would have some sort of real-time imaging system that would provide information on how deeply and how intensely the tissue has been heated. Ultrasound may be the solution.
