Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. view more (2007-07-31)

Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes. view more (2008-08-29)
Software-defined radio simplifies mobile phones
Mobile phones are getting more and more complicated. One reason is that a new radio is needed for each standard-GSM, 3G, and WLAN. A simpler solution, a radio that can be programmed to cover all standards, is now being developed at the Stringent Research Center at Linköping University in Sweden. "We have come up with three concepts... view more... (2004-04-19)
MIT: engine on a chip promises to best the battery
MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight can, powering laptops, cell phones, radios and other electronic devices. view more (2006-09-26)
Tough new probe developed for nanotechnologists
Since the invention of the atomic force microscope (AFM) in 1986 by Nobel laureate Gerd Binnig, the tool has been employed to advance the science of materials in many ways, from nanopatterning (dip-pen nanolithography) to the imaging of surfaces and nano-objects such as carbon nanotubes, DNA, proteins and cells. In all these applications, the... view more... (2005-08-11)
Scientists from the UAB and ICMAB achieve unprecedented control of formation of nanostructures
A team of researchers from the Universitat Autònoma de Barcelona, together with researchers from ICMAB (CSIC) and other Russian and Ukrainian scientists, have discovered an unprecedented method for accurately controlling the formation of nanometric structures made of semiconducting material in the form of islands, using promising... view more...

MAXUS 4 is now ready for launch
Following the success of the earlier Maxus flights which have taken place since 1992, the countdown is underway for the launch of ESA’s Maxus 4 sub-orbital microgravity mission on 29 April from ESRANGE, near Kiruna in northern Sweden. During the last two years, scientists from five European countries have been working together with the... view more... (2001-04-26)
Where has all the antimatter gone?
Scientists from the Universities of Liverpool and Glasgow have completed work on the inner heart of an experiment which seeks to find out what has happened to all the antimatter created at the start of the Universe. view more (2007-04-12)
Perfect image without metamaterials ... and a reprieve for silicon chips
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. view more (2009-09-29)
ETH Zurich Develops a Single-chip Microsensor System to Analyse Gases
There are many target application areas envisaged for the gas sensor chip. Air quality in closed rooms can be monitored. The presence of dangerous - even poisonous - substances in the air can be detected, such as benzene from petrol pumps or perchloroethylene from dry-cleaning installations, and warnings can then be issued. Low-cost Mass... view more... (2001-11-14)
Keen Sense Of Smell
A unique device has been designed by the Moscow scientists - specialists of the Institute of General Physics, Russian Academy of Sciences, supported by funding from the Russian Foundation for Basic Research. The device not only helps to discover in a few seconds the minute quantities of narcotics and explosives in the air, but to identify and even... view more... (2003-10-31)
Astronomers detect stellar ashes at dawn of time
Using a powerful instrument on a telescope in Hawaii, UK astronomers have found ashes from a generation of stars that died over 10 billion years ago. This is the first time that the tell-tale cosmic dust has been detected at such an early stage in the evolution of the universe. view more (2002-04-10)
Unusual meteorite unlocks treasure trove of solar system secrets
An unusual meteorite that fell on a frozen lake in Canada five years ago has led a Florida State University geochemist to a breakthrough in understanding the origin of the chemical elements that make up our solar system. view more (2005-09-28)
