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.  Read More

Researchers say their new spectrometer will help speed the cleanup of nuclear waste sites ...

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.  Read More

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.  Read More

Sewage plants like this could soon be soon be self-sufficient in terms of energy usage (Im...

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

Experimental setup for THz-pump and optical-probe measurements used by the researchers

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

In the search for a hot-melt composite adhesive Professor Kaichang Li noticed a sticky res...

It happens often in research. While looking for one thing, scientists stumble across another. In this case, researchers at Oregon State University's College of Forestry were looking for an elusive wood-based adhesive that would be solid at room temperature but melt when the heat was turned up. What they stumbled upon was an easily produced, environmentally benign, pressure sensitive adhesive which holds the potential to be cheaply produced from a wide range of vegetable oils.  Read More

Zinc oxide coatings on copper or aluminum substrates has proven the best heat dissipation ...

In a finding that could well revolutionize cooling technology as we know it, researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a way to achieve near-optimal heat dissipation by applying a nanostructured coating. Because of performance, versatility and economy of materials used, their method could soon lead to better electronics, heating and air conditioning.  Read More

Nanostructure films, resembling millions of tiny pyramids, reduce the reflectance of any l...

Nanotechnology applications are increasingly diverse - ranging from being used to acquire fingerprints, to their use in the field of spintronics or even to help in the fight against cancer. Now a team of chemical engineers at Oregon State University has invented new technology that allows them to coat various surfaces with “nanostructure films”, which could be used to make cheaper, more effective eyeglasses and eventually, more efficient solar cells.  Read More
