Automated screening process may eventually reduce additional breast cancer surgeries
A team of researchers at the University of California, San Diego (UCSD) and the Moores UCSD Cancer Center have developed a rapid, automated image screening process to distinguish breast cancer cells from normal cells. view more (2009-02-02)
Photonic Crystals in 3-D - The Physics Congress 2003
Telecoms systems contain an awkward mixture of optics and electronics. A purely optical system would permit the very high data rates needed by the Internet, but at the moment the switching and routing, as well as the "last mile" to the customer, still depend on slower electronic components. Speaking at the Institute of Physics Congress... view more... (2003-03-17)
Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. view more (2008-03-28)
Blacksmith’s secret revealed
In an international study into the fine structure of steel, Technology Foundation STW researchers have revealed how strong steel is formed. By analysing red-hot steel with an x-ray microscope, the researchers discovered how at a temperature of 900 oC, numerous microscopic crystals suddenly developed in the steel. The findings were published in the... view more... (2002-11-15)
New advances in detection and identification technology from Oxford University
Increasingly, industry demands technologies that enable detection and identification of targets, ranging from information for traffic tolling and airspace management to patient supervision in hospitals, security passes and stock control. Researchers at Oxford University's Department of Engineering Science have developed new retroreflectors that... view more... (2002-07-01)
Bird Feathers Produce Color Through Structure Similar to Beer Foam
Some of the brightest colors in nature are created by tiny nanostructures with a structure similar to beer foam or a sponge, according to Yale University researchers. view more (2009-04-06)
A self-orienting colibri
A new optical 3D measuring system was named like the bird ”kolibri-mobil“. While self-calibrating, it does not require any orientation marks. Precise measurement data are taken from complex objects in a single test step and the computer visualizes them in three dimensions. -------------- This ”Kolibri“ has nothing to do... view more...

Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins. Like a line of silent ballet dancers, long-chain... view more... (2004-05-14)
Smart Optics Faraday Partnership announces £1M funding opportunity for flagship projects.
Companies in the aerospace, healthcare, telecoms and optics industries are set to benefit under a £1M call for collaborative project proposals announced by the new Smart Optics Faraday Partnership ("SmartOptics"), sponsored by the DTI, PPARC and EPSRC. Applications for significant "flagship" projects are now sought. These will... view more... (2001-11-16)
Silicon photonic crystals key to optical cloaking, researchers say
In computer simulations, the researchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking. view more (2008-06-26)
NIST math technique opens clearer window on universe
A fast, efficient image enhancement technique developed at the National Institute of Standards and Technology (NIST) and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale- sharpening details on color images of distant galaxies produced by the Hubble Space Telescope. view more (2006-12-11)
Raman Effect Brings Nano up to Size : Raman/Rayleigh Imaging of Nanosized Materials
Materials made with (or from) nanophases received considerable attention in the last few years but their characterisation is not easy. Unique properties (conductivity, diffusion, reactivity, sintering, mechanical strength….) have been reported for nanostructured materials, all of which result from the interfacial characteristics. Raman... view more... (2003-06-08)
Patent Granted For A Chemical Compound That Acts As A Molecular Switch
The University Jaume I (UJI), together with researchers from the CSIC and the Universitat Polite'cnica de Vale'ncia, has patented a new compound whose physico-chemical characteristics open up a wide range of technological applications. The compound is one of the metallodendrimers, which are molecules that undergo reversible changes in their... view more... (2004-06-30)
Opals manufactured by beetles
The gemstone opal could be manufactured synthetically copying a technique employed by a beetle to control the appearance of its outer shell. Researchers from the Department of Zoology at the University of Oxford have discovered the first case of opal in an animal, in this case in the weevil Pachyrhynchus argus, found in forests in north-eastern... view more...

Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
Laser-optical mine detection needle will facilitate mine clearing
The "laser-optical mine detection needle" is intended to facilitate the removal of land mines for humanitarian reasons. The working group of Professor Dr. Wolfgang Schade at the Institute of Physics und Physical Technologies at the Technical University of Clausthal intends to exhibit a "laser-optical mine detection needle" at... view more...

Pressure relief for jet engines - Photon02
The aerodynamics inside jet engines are not completely understood due to the unpredictable nature of the air flowing through the turbine. However, a research team led by Dr Jim Barton from Heriot-Watt University, has developed tiny fibre optic pressure sensors that can for the first time be used inside jet engine test rigs. These sensors should... view more... (2002-08-28)
Nanofabrication method paves way for new optical devices
An innovative and inexpensive way of making nanomaterials on a large scale has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties. view more (2007-10-08)
Magnetism flicks switch on 'dark excitons'
In new experimental research appearing in this week's issue of Physical Review Letters, a Rice University-led team of nanoscientists and electrical engineers has flipped the switch on 'dark excitons' in carbon nanotubes by placing them inside a strong magnetic field. view more (2006-01-11)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
