Your next colored bracelet can detect environmental pollution

Posted on 21/04/2016 by Timothy J. Seppala

Turns out your collection of neon-colored silicone bracelets have a use beyond showing support for a fallen-from-grace cyclist's non-profit after all. The material can actually trap pollutants you might be exposed to during the course of your day, ac...

Researchers claim ‘almost instantaneous’ quantum computing breakthrough

Posted on 05/09/2013 by Timothy J. Seppala

Silicon is great, but we're tickling the edges of its speed limit. As a result, researchers at Oregon State University have been plugging away at a low-cost, faster alternative for the past three years: tiny quantum devices called metal-insulator-metal diodes, or MIM diodes for short. Silicon chips involve electrons traveling through a transistor, but MIM diodes send electrons "tunneling" through the insulator in a quantum manner, such that they appear "almost instantaneously" on the other side. The tech's latest development doubles the insulator fun -- transforming the MIM into a MIIM (pictured above) -- giving the scientists another method for engineering quantum mechanical tunneling. With MIIMs, super fast transistor-less computers could be around the corner. The Oregon researchers aren't bold enough to put a date on making any of this happen outside of the lab, but they promise entire new industries may "ultimately emerge" from their work, and we're far too under-qualified to doubt them.

Researchers create super-efficient microbial fuel cell, dream of selling excess electricity

EDIT Researchers create superefficient microbial fuel cell, dream of selling excess electricity

Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons -- rather than the hydrogen or methane that other methods rely upon -- are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn't just for processing what comes out of the porcelain throne -- it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.
