Advance could turn wastewater treatment into viable electricity producer

By - August 14, 2012 1 Picture
In the latest green energy – or perhaps that should be brown energy – news, a team of engineers from Oregon State University (OSU) has developed new technology they claim significantly improves the performance of microbial fuel cells (MFCs) that can be used to produce electricity directly from wastewater. With the promise of producing 10 to 50 times the electricity, per volume, than comparable approaches, the researchers say the technology could see waste treatment plants not only powering themselves, but also feeding excess electricity back to the grid.

"Cool blue" pigment could boost energy efficient building

Researchers at Oregon State University have discovered a new type of blue pigment that could help boost the energy efficiency of buildings. Discovered unexpectedly three years ago, the "cool blue" pigment has unusually high infrared heat reflectivity which it is hoped can be channeled into commercial products in the near future.

Researchers cut waste and lower cost of 'CIGS' solar cells using inkjet printing technology

By - June 28, 2011 1 Picture
Traditional solar cell production techniques are usually time consuming and require expensive vacuum systems or toxic chemicals. Depositing chemical compounds such as CIGS on a substrate using vapor phase deposition also wastes most of the expensive material in the process. For the first time, engineers at Oregon State University (OSU) have now developed a process to create "CIGS" solar cells with inkjet printing technology that allows for precise patterning to reduce raw material waste by 90 percent and significantly lower the cost of producing solar cells with promising, yet expensive compounds.

'Thermally activated cooling system' puts waste heat to use

By - June 13, 2011 1 Picture
Automobiles, appliances, power plants, factories and electrical utilities all waste one thing: heat. More specifically, they produce heat as a by-product of their normal operations, but that heat is just dispersed into the air instead of being put to use. Researchers from Oregon State University, however, have created a prototype system that harnesses waste heat to (rather ironically) cool the device that’s creating the heat in the first place. While it isn’t the first system to do so, it is claimed to be unusually efficient ... and, it can generate electricity. Read More

Magnetic nanobead technology could result in better biosensors

By - April 29, 2011 1 Picture
Handheld biosensors and diagnostic devices could be taking a huge step forward, thanks to recent advances made in the use of ferromagnetic iron oxide nanoparticles – also known as magnetic nanobeads. According to scientists from Oregon State University (OSU), the use of such particles in chemical detection systems could make those systems much smaller, faster, cheaper to produce, and more accurate than they are presently.

New spectrometer developed for faster cleanup of nuclear-contaminated sites

By - January 2, 2011 1 Picture
The cleanup of sites contaminated by radioactivity, primarily from the historic production of nuclear weapons during and after World War II, continues to cost hundreds of millions of dollars. Researchers have now invented a new type of radiation detection and measurement device that they say will be particularly useful for such cleanup efforts by making the process faster, more accurate and less expensive.

Revolutionary diode design cracks 50 year-old electronics speed barrier

By - November 8, 2010 0 Pictures
Metal-insulator-metal (MIM) diodes might just be the technology that allows electronics achieve the next big leap in processing speed. Research into diode design conducted at the Oregon State University (OSU) has revealed this week cheaper and easier to manufacture MIM diodes that will also eliminate speed restrictions of electronic circuits that have baffled materials researchers since the 1960's.

Nanotech coatings offer possibility of ‘brown’ electricity from sewage

By - July 22, 2010 3 Pictures
While much of the focus on renewable electricity production focuses on green alternatives, a team of engineers at Oregon State University is looking at ways to improve electricity production from a “brown” source – namely sewage. The engineers found that using new coatings on the anodes of microbial electrochemical cells they were able to increase the electricity production from sewage about 20 times. Read More

‘Terahertz’ speed signal processor an important step for optical computing

By - July 20, 2010 1 Picture
It’s a sign of the times when the speed of electrons moving through wires is seen as pedestrian, but that’s increasingly the case as technology moves towards the new world of optical communication and computing. Optical communication systems that use the speed of light as the signal are still controlled and limited by electrical signaling at the end. But physicists have now discovered a way to use a gallium arsenide nanodevice as a signal processor at “terahertz” speeds that could help end the bottleneck. Read More
