‘Dancing’ atoms may lead to logic switches, nano-scale detectors

By / November 21, 2008

Two Johns Hopkins researchers believe they have developed a new method to use lasers to manipulate electrons in a crystal array, and if the discovery holds up to testing, it could lead to new forms of computer memory, biohazard alarms and cancer cell detectors. Alexander Kaplan, a professor in the Department of Electrical and Computer…

China tops list of CO2 emitters

By / November 20, 2008

The world’s carbon dioxide emissions have escalated 38 percent since 1992, climbing from 6.1 billion tons in 1992 to 8.5 billion tons last year, according to DOE’s Carbon Dioxide Information Analysis Center, located at Oak Ridge National Labs. In 1992, the United States headed the list of the world’s top five CO2 emitters. The rest of…

CO2 sequestration leaps forward with new basalt study

By / November 18, 2008

Federal scientists working at PNNL today unveiled results of research that appear to show that carbon dioxide can be permanently stored in deep underground basalt formations with little or no threats to safety. A PNNL news release states that facility staff “have discovered key factors that show water-saturated liquid CO2, under conditions mimicking deep geologic…

Nanotube speakers – The next “big” thin thing

By / November 17, 2008

What’s transparent, stretchable, nearly weightless, flexible enough to be sown onto a shirt and plugs into your iPod? Maybe, soon, this may describe one of the best and most durable audio speakers you’ll ever own. A group of Chinese researchers have discovered that, by zapping an audio-frequency current through a carbon nanotube thin film, it…

Video of the week – aerogels

By / November 12, 2008

This week’s video is actually a three-in-one aerogel feature. Aerogel is wispy, translucent, highly insulating material often described as “solid smoke.” It’s worth noting that aerogel is not a new material and may date back to the 1930s. Many new applications and lower-cost production processes, however, are opening up. The first part of the video…
