IBM Creates a New Way to Make Faster and Smaller Transistors

IBM Creates a New Way to Make Faster and Smaller Transistors | TechWatch | Scoop.it

Researchers at IBM have assembled 10,000 carbon nanotube transistors on a silicon chip. With silicon transistors approaching fundamental limits to continued miniaturization, theIBM work points toward a possible new way of continuing to produce smaller, faster, more efficient computers.

 

Earlier work by IBM showed that nanotube transistors could run chips three times faster than silicon transistors while using only a third as much power. And at just two nanometers in diameter, the nanotubes—carbon molecules resembling rolled-up chicken wire—are so small that chip makers could theoretically cram far more transistors on a chip than is possible with silicon technology. But controlling the nanotubes’ placement in arrays numerous enough to be useful—ultimately, billions of transistors—is a major research challenge.

Nanoparticles Make Steam without Bringing Water to a Boil

Nanoparticles Make Steam without Bringing Water to a Boil | TechWatch | Scoop.it

A new trick could reduce the energy needed for many industrial processes and make solar thermal energy much cheaper.

 

Steam is a key ingredient in a wide range of industrial and commercial processes—including electricity generation, water purification, alcohol distillation, and medical equipment sterilization.

 

Generating that steam, however, typically requires vast amounts of energy to heat and eventually boil water or another fluid. Now researchers at Rice University have found a shortcut. Using light-absorbing nanoparticles suspended in water, the group was able to turn the water molecules surrounding the nanoparticles into steam while scarcely raising the temperature of the remaining water. The trick could dramatically reduce the cost of many steam-reliant processes.

IBM's 3 big chip breakthroughs explained

IBM's 3 big chip breakthroughs explained | TechWatch | Scoop.it

IBM has made three breakthroughs that could help chips continue following Moore’s Law. Monday at the IEEE International Electron Devices Meeting, IBM showed off the first racetrack memory device that delivers an entirely new means to get electrons to hold data, as well as two materials breakthroughs that could lead to faster chips and even open up new spectrum bands that would be useful for delivering mobile
