Advance makes thermoelectrics twice as efficient

By / September 12, 2008

Ohio State University researchers say they have invented a new material that “will make cars even more efficient by converting heat wasted through engine exhaust into electricity” and with “twice the energy efficiency” of any thermoelectric material currently on the market. Lead researcher Joseph Heremans, an OSU professor of mechanical engineering and physics, reports on the new…

Growing smart materials idea comes from trees

By / September 10, 2008

What is the best way to move substances from one place to another – a key consideration when developing complex new “smart” materials? Duke University researchers believe they have found the answer to this question in the canopy of trees. Adrian Bejan, a professor of mechanical engineering at Duke’s Pratt School of Engineering, is the developer…

Brick, stained glass that cleans the air

By / September 5, 2008

We came across two very different stories about passive methods that can produce cleaner air – methods developed centuries apart. First, in a test that may lead to a breakthrough in the reduction of air pollution, the town of Hengelo in the Dutch province of Overijssel is paving one of its roads with concrete brick…

Graphene memory possible?

By / August 26, 2008

Writers at the IEEE Spectrum report that molecule-size memory may be possible using graphene. Electrons flow extremely fast in graphene, much faster than in silicon, and a graphene transistor could really zip. That’s been the good news. The bad news, until now however, is that it’s hard to stop current from flowing in graphene once…

Missouri S&T working on bringing hydrogen to market

By / August 25, 2008

A group of researchers at Missouri University of Science and Technology have received funding from the DOE to develop a real-world overview of the possible uses for hydrogen in the relatively near future. “We need to be realistic about what we can and can’t do with hydrogen right now,” says Dr. Scott Grasman, associate professor…

New “skin” to provide more human touch

By / August 24, 2008

Science Magazine has published research suggesting that Japanese scientists have developed a composite skin that is both stretchable and able to conduct electricity, leading researchers at the University of Tokyo to predict robotic applications covered with the material that can both feel heat and pressure. The problem they have been trying to address is that…

Nanotech market to reach $3.1 trillion by 2015

By / August 18, 2008

A new report from Lux Research claims that nanotechnology, while perhaps overhyped in the past, has now become pervasive in a broad range of sectors. “Nanomaterials State of the Market Q3 2008: Stealth Success, Broad Impact,” predicts that $147 billion worth of nano-enabled products produced in 2007 will grow to $3.1 trillion by 2015.To estimate nanotech’s commercial impact, Lux looked at the technology’s effect in three major industry sectors – manufacturing and materials, electronics and IT, and healthcare. The firm bases its predictions on more than 1,000 interviews conducted with technology developers and a new survey of 31 leading corporations in the nanotechnology field.
