Near-IR Technique Sheds Light on Kinetic Reactions
Aug 1, 1999 — Chemists at Marquette University in Milwaukee have used a multispectral imaging spectrometer constructed with an acousto-optic filter and an InGaAs focal plane array to study the kinetics of curing an epoxy resin. The researchers’ results obtained using their device corresponded closely with conventional Fourier transform infrared (FTIR) analysis. Their customized spectrometer also offers more capabilities than conventional FTIR spectrometers, such as providing kinetic information...
New Findings on Single-Shot Laser Pulse Damage
Aug 1, 1999 — Laser damage on short time scales is an area of active research. Because short pulses produce damage with a smaller statistical uncertainty than long pulses, femtosecond lasers for submicron-precision material removal have become attractive....
Nitrogen Splits GaInAs Conduction Band
Aug 1, 1999 — Researchers at the Lawrence Berkeley National Laboratory reported that the presence of a nitrogen band formed a few tenths of an electron volt above the lowest energy conduction band in a gallium indium arsenide alloy material. Although the addition...
Optical Coherence Tomography Expands Its Scope
Aug 1, 1999 — Optical coherence tomography, recognized in biomedical circles as an excellent imaging method, is expanding its field of view into materials applications, most recently the nondestructive imaging of composites. Optical coherence tomography...
Optical Sensor Catches Drug Abusers
CAMBRIDGE, UK -- CAMBRIDGE, UK -- Optical sensors that detect biochemical reactions at the molecular level could be used to spot drug abuse by athletes within minutes. The technology promises to be a great improvement over traditional chemical analysis of blood or...
Organic LEDs May Improve Microdisplays
Aug 1, 1999 — Organic light-emitting diodes (LED) offer several key advantages over conventional LEDs. Their high efficiency and resolution make them well-suited for integration on silicon integrated circuits and high-performance microdisplay systems. Fed Corp....
Researchers Achieve Higher Bandwidth over Single-Mode Fiber
Aug 1, 1999 — A technology that would improve the transmission capacity of wavelength division multiplexing (WDM) systems on standard single-mode fiber may affect the majority of installed fiber networks. Researchers from Pirelli Cables and Systems of Milan,...
Sapphire Probe Offers Wide Dynamic Range
Aug 1, 1999 — Fiber optic temperature sensors offer wide dynamic range, immunity to electromagnetic interference and high sensitivity. They are typically used for measuring temperatures in applications such as plasma deposition. A sapphire-fiber thermometer with...
Sensor Cultivates Agricultural Markets
DÜLMEN, Germany -- DÜLMEN, Germany -- Each spring, a crop is planted down on the farm operated by Hydro Agri. And each fall, along with the produce, researchers reap data on the effectiveness of various fertilizer materials. While these materials optimize the...
Solvents Polish Porous Silicon’s Efficiency
MALVERN, UK -- MALVERN, UK -- With regard to porous silicon, efficiency applies both to the material’s light-emissive qualities and to its cost-performance ratio. But until recently, stability has not been among the material’s strong points (Photonics...
Telescope Puts the Universe in Focus
Aug 1, 1999 — In June, astronomers gave the public a glimpse of some of the sharpest IR images ever obtained by a ground-based telescope. The images from the Gemini North Observatory on the island of Hawaii show the power of the new telescope, which minimizes the...
US, Japan Track Ghostly Neutrinos
Aug 1, 1999 — Since the first neutrinos were detected more than four decades ago, researchers have sought better ways of detecting these elusive, high-energy particles that originate from nuclear reactors and outer space. Japan and the US have teamed up to...
X-rays Monitor Electron Density
SAN DIEGO — A team at the University of California used picosecond x-ray diffraction to measure the response of GaAs crystal to sudden heating. This could advance efforts to monitor changes in electron density during biological and chemical reactions with...
’Laser Hatching’ Proves Successful
Jul 1, 1999 — The first births resulting from pregnancies initiated by laser-assisted hatching could signal the emergence of photonics in in vitro fertilization. The births -- a boy in the US and twins in Australia -- were part of ongoing clinical trials of the...
Afterglow Gives Clues to Gamma Ray Bursts
Jul 1, 1999 — Since their discovery in 1967, intense gamma ray bursts in the universe have mystified scientists. Now a group of scientists led by Alberto J. Castro-Tirado of the Instituto de Astrofisica de Andalucia in Spain has presented findings that may...
Air Force Opens Imaging and Radar Test Facility
Jul 1, 1999 — The US Air Force has improved its ability to measure stealth characteristics of enemy planes with the operation of an upgraded test facility able to conduct wide-bandwidth bistatic imaging and radar cross-section measurements of full-size planes....
Cleaved Gallium Nitride Proposed for Blue Laser Diodes
Jul 1, 1999 — Researchers from Technische Universitat Berlin have reported observing optically excited stimulated emission of cleaved c-GaN samples grown by molecular beam epitaxy. They report that the threshold intensity for excitation from c-GaN layers is lower...
Fiber Optic Unit Promises More Crash Data
SUDBURY, Mass. -- SUDBURY, Mass. -- Airplane crash investigations have been hindered by limited flight data, prompting the National Transportation Safety Board and the Federal Aviation Administration (FAA) to push for more recorded information so they can determine...
Largest Laser Shocks Diamond into Metal
LIVERMORE, Calif. -- LIVERMORE, Calif. -- Though physicists may be jumping for joy, those who consider diamonds their best friends won’t be. Scientists at Lawrence Livermore National Laboratory have turned diamond into metal. Using the Nova laser, whose 10 beams...
Laser System Spots Dirty Laundry
Jul 1, 1999 — Spectra Science Corp. in Providence, R.I., has demonstrated a laser-based system that identifies, counts and classifies soiled flat linens. The demonstration took place at Tartan Textile Services in Houston. The system uses a laser to scan linens...
Lasers Burst Across a Frontier
LIVERMORE, Calif. — At Lawrence Livermore National Laboratory, researchers have crossed a threshold. They've constructed a laser that creates conditions until now found only in massive particle accelerators or in the centers of stars. At Lawrence Livermore National...
Los Alamos Lab to Improve Images
LOS ALAMOS, N.M. -- LOS ALAMOS, N.M. -- Imaging the Earth’s surface through the atmo-sphere presents many challenges. But the launch Oct. 31 of a satellite carrying an advanced multispectral thermal imager could overcome them. The instrument’s 15-band...
New Method Looks Inside Living Cells
STANFORD, Calif. -- STANFORD, Calif. -- Many chemical reactions occurring in living organisms are both fast (in the microsecond to millisecond range) and spatially confined. Viewing biochemical processes in volumes from zeptoliters to femtoliters (1021 to 1015 liters)...
Novel LEDs Could Eliminate Bacteria
LONDON — A new resonant cavity light-emitting diode (LED) could help to eradicate antibiotic-resistant bacteria, emitting the necessary light (670 to 680 nm) to activate special bug-killing chemicals. Conventional LEDs are already used in photodynamic...
Optical Fiber Senses Spills
MANCHESTER, UK — The rapid, pinpoint accuracy of optical time domain reflectometry could find new use in detecting pipeline leaks and spills. Energy and chemical companies now visually examine pipelines from a vehicle or helicopter, but finding leaks can be...
