Scientists close in on a single-molecule diode

Scientists close in on a single-molecule diode

Researchers at Columbia University School of Engineering have developed a technique creating working diodes that consist of only a single molecule. These molecular diodes are capable of performing 50 times better than previous incarnations of nanoscale diodes. The research group, led by associate professor of applied physics, Latha Venkataraman, could be the first single-molecule diode that is efficient enough to have real-world applications, like incorporation into other nanoscale devices. The new discovery is detailed in the article published in the journal Nature Nanotechnology.

Targeted nano-particles can now prevent heart attacks

Targeted nano-particles can now prevent heart attacks

Soon it may be possible to prevent heart attacks by an injection of nano-particles into the bloodstream, according to the newest research paper from the scientists at Columbia University Medical Hospital and Brigham and Women's Hospital. Heart disease is the leading cause of death in America. A large part of that is atherosclerosis, or hardening of the arteries. This occurs as plaques build up along the inside of the arterial wall. The research team created targeted nano-particles designed to heal atherosclerosis. This is the latest discovery in a growing field of pint-sized medical discoveries. We've seen robots that can swim inside your eyeball and smart pills, but nothing as small as this nano-treatment.

Lasers and carbon-nanotubes pave way to live brain scanning

Lasers and carbon-nanotubes pave way to live brain scanning

Lasers and carbon nanotubes peering into the brain might sound like the stuff of science fiction, but tests that could one day mean precise non-invasive diagnosis of Alzheimer's, Parkinson's, and other diseases are already underway. The technology, developed by chemists at Stanford University, has so far been tested on mice, but opens the door to an alternative to physically removing sections of the skull to track cellular-level changes.

This self-cleaning car tech could change everything

This self-cleaning car tech could change everything

Rich chocolate syrup on a pure white car would usually be the trigger for a trip to the detailing shop, but this time around there's something different: like the black oil from the X-Files, the syrup beads up and oozes off the edge of the hood, leaving no trace that it was ever there. Nissan's calling it "the World's Cleanest Car," but there's more to this special Leaf EV than a fetching matte paint-job.

One day these nanowires will make your whole dashboard touch

One day these nanowires will make your whole dashboard touch

If "wearable" is the big buzzword of CES this year then "flexible" can't be far behind. Cambrios Technologies isn't a company you might associate with it - LG's G Flex and Samsung's transforming curved TV are certainly more eye-catching - but the company's ClearOhm silver nanowires are likely to enable the next generation of flexibly flexible touch panels, including turning your whole car dashboard into one vast finger-responsive surface.

Carbon nanotube headphones create sound using thermoacoustic effect

Carbon nanotube headphones create sound using thermoacoustic effect

Over the years, headphones have become very ubiquitous. You can buy them for a few dollars in the checkout lane at your local Walmart and many smartphones ship with a cheap generic pair of headphones right and the box. It also spend hundreds of dollars on audiophile grade headphones. One thing that all these headphones have in common is that they utilize speaker drivers on the inside that rely on moving parts to create sound. Scientists have created a new type of headphone that uses carbon nanotubes and features no moving parts.
