Nanotech's Contribution to the CES 2010 Show

Nanotech's representation at Consumer Electronics Show still takes the form of materials rather than devices enabled by it

Nanotech's Contribution to the CES 2010 Show

I have to hand it to IEEE Spectrum. Its new website format has allowed me to easily follow all the coverage from the CES 2010 show this year by just clicking on the subchannel “Consumer Electronics” and finding everything in one place.

But to find how nanotechnology might be enabling any of these gizmos one has to dig a little deeper, so it wasn’t clear what kind of role nanotech was playing at the CES show this year.

And then I found this article in which Nanosys, once touted as the IP king of nanotech with its 500 patents, was sending its CEO to CES show to demonstrate how their nanomaterials can give LED lights a more vivid color with the same amount of energy.

Unfortunately from the article it didn’t appear as though Nanosys was demonstrating any LED device enabled by the nanomaterial; instead they just demonstrated the nanomaterial. It would seem Nanosys plans to sell the material to companies that make LED devices following the business model of being a material supplier rather than a device manufacturer.

With this in mind, the article goes on to predict that we should see some devices equipped with nano-enabled LEDs some time this year. Question is, will the nanomaterials actually be from Nanosys?

YOU'VE PROBABLY PLAYED hundreds, maybe thousands, of videos on your smartphone. But have you ever thought about what happens when you press “play”?

The instant you touch that little triangle, many things happen at once. In microseconds, idle compute cores on your phone's processor spring to life. As they do so, their voltages and clock frequencies shoot up to ensure that the video decompresses and displays without delay. Meanwhile, other cores, running tasks in the background, throttle down. Charge surges into the active cores' millions of transistors and slows to a trickle in the newly idled ones.
