Archaeology Digs Photonics
Even by the standards of his day, the fictional archaeologist “Indiana” Jones lacked the proper tools. It is hard, after all, to carefully dig up a shard of pottery and gently brush away dirt from it using a bullwhip. Nonetheless, a more accurately portrayed — albeit less swashbuckling — archaeologist might have performed his job a century ago not much differently than modern investigators, according to Thomas E. Levy, professor of anthropology and Judaic studies at the University of...

Better OLEDs, Perhaps, Thanks to a Holey Electrode
The makers of organic LEDs face a challenge. The devices are constructed from a series of organic semiconductor layers sandwiched between a cathode and anode, which must be conductive and transparent. Unfortunately, the best and least expensive...

Getting Juiced
Sugar is sweet, but sometimes its use can lead to bitter results. Such is the case with fruit juice when unscrupulous suppliers use sugar solutions as a replacement for high-cost ingredients in juice drinks to cut costs. Similarly, substituting...

Managing Light to Increase Efficiency in LCDs
Consumers plan to purchase 72 million LCD TVs in 2007 and 98 million in 2008, when sales will surpass cathode-ray tube TV unit sales for the first time, according to the research firm DisplaySearch of Austin, Texas. The industry is racing to build...

Manufacturing Large LCDs while Maintaining Yields
As thin-film transistor LCD panel makers produce increasingly larger televisions, fewer displays fit onto the glass substrate during the production process. Whereas fifteen 32-in.-wide displays fit onto an eighth-generation substrate, only six...

Measuring Life’s Limits in the Ocean
Sea life may not lack water for survival, but marine organisms do need nutrients such as nitrate, phosphate, silicate and iron. Researchers, therefore, want an accurate, high-resolution profile of nutrient concentrations in the open ocean, which is...

Nanoscale Light Detectors Provide Mega-Performance
On the surface, nanowires would seem to make poor light detectors, but it is a nanowire’s surface that produces just the opposite outcome. Those are the findings of a team of scientists from the University of California, San Diego, that investigated...
