Scientists with the Ernest Orlando Lawrence Berkeley National Laboratory have confirmed the existence of atom-sized electronic devices on nanotubes, hollow cylinders of pure carbon about 50,000 times more narrow than a human hair in diameter. Nanotube devices have been predicted by theorists but this is the first demonstration that such devices actually exist. Alex Zettl, a physicist with Berkeley Lab's Materials Sciences Division (MSD) and a professor of physics on the University of California's Berkeley campus, led a study in which nanotubes of pure carbon were shown to function as a two-terminal electronic device known as a diode. "What we are seeing is the world's smallest room-temperature rectifier, one that is only a handful of atoms in size," says Zettl. "When we grow nanotubes, electronic devices naturally form on them." Carbon nanotubes are created by heating ordinary carbon until it vaporizes, then allowing it to condense in a vacuum or an inert gas. Depending upon its diameter, a pure carbon nanotube can conduct an electrical current as if it were a metal, or it can act as a semiconductor. Zettl does not expect nanotubes to replace silicon overnight in the electronics industry but can see this as a possibility down the road.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
