- Beyond batteries: Storing power in a sheet of paper
08-13-2007 · EurekAlert!
Rensselaer Polytechnic Institute researchers have developed a new energy storage device that could be mistaken for a simple sheet of paper. The nanoengineered battery is lightweight, flexible and geared toward meeting the design requirements of tomorrow's electronics and implantable medical equipment. The device withstands extreme temperatures, is completely integrated, can be printed like paper, and can function as both a battery and a supercapacitor. It can also be partly powered by human blood or sweat.

- Graphene oxide paper could spawn a new class of materials
07-25-2007 · EurekAlert!
Researchers at Northwestern University have fabricated graphene oxide "paper" -- a remarkably stiff and strong yet lightweight material that should find use in a wide variety of applications. This new type of paper is more than five inches in diameter and with thicknesses from about one to 100 microns, in which the individual micron-sized graphene oxide sheets are stacked on top of each other.

- Scientists observe drumlin beneath ice sheet
01-23-2007 · EurekAlert!
Scientists have discovered a warehouse-sized drumlin -- a mound of sediment and rock -- actively forming and growing under the ice sheet in Antarctica. Its discovery, and the rate at which it was formed, sheds new light on ice-sheet behavior. This could have implications for predicting how ice sheets contribute to sea-level rise. The results are published this week in the journal Geology.

- Ceramic Microreactors Developed For On-site Hydrogen Production
10-02-2006 · ScienceDaily
Scientists at the University of Illinois at Urbana-Champaign have designed and built ceramic microreactors for the on-site reforming of hydrocarbon fuels, such as propane, into hydrogen for use in fuel cells and other portable power sources.
Applications include power supplies for small appliances and laptop computers, and on-site rechargers for battery packs used by the military.

- Researchers create new super-thin laser mirror
02-13-2007 · EurekAlert!
Engineers at UC Berkeley have created a new high-performance mirror that packs the same 99.9 percent reflective punch as current high-grade mirrors, but in a package that is 20 times thinner and easier to manufacture. The new mirror could dramatically improve the design and efficiency of next generation laser optics for such devices as high-definition DVD players, computer circuits and laser printers.

- Nanoscale imaging reveals unexpected behaviors in high-temperature superconductors
05-30-2007 · EurekAlert!
Recent discoveries regarding the physics of ceramic superconductors may help improve scientists' understanding of resistance-free electrical power. Tiny, isolated patches of superconductivity exist within these substances at higher temperatures than previously were known, according to a paper by Princeton scientists, who have developed new techniques to image superconducting behavior at the nanoscale.

- Minuscule molecules pack a powerful punch
04-26-2007 · EurekAlert!
A role for a microRNA in the immune system has been shown by study of one of the world's first microRNA knockout mouse, reported Friday, April 27, in Science. The microRNA acts as a lynchpin to balance the response of immune defences and the researchers suggest the corresponding human gene will have a similar vital role.
