Researchers Create Smallest Transistor Ever

Schematic of a transistor with a molybdenum disulfide channel and 1-nanometer carbon nanotube gate. (Credit: Sujay Desai/UC Berkeley) For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometer-gate transistors now on the market. But some laws are made to be broken, or at least challenged.

T-rays Will “Speed Up” Computer Memory By a Factor of 1,000

The figure shows the spin and lattice structure of thulium orthoferrite (TmFeO₃) on the left and the T-ray-induced transitions between the energy levels of thulium ions (Tm³⁺), which trigger coherent spin dynamics (memory switching), on the right. Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer performance. They propose the use of so-called T-waves – or terahertz radiation – as a means of resetting computer memory cells. This process is several thousand times faster than magnetic-field-induced switching.

Nasa Processing Technologies Enable Advanced Computing Applications

Embedded processing technologies developed at NASA field centers are enabling the use of next-generation computer-controlled instruments and spacecraft, including SpaceCubes, integrated photonics modems, and new ways to manufacture computer components. SpaceCube ProcessorsNext-generation spacecraft instruments are capable of producing data at rates of 108 to 1011 bits per second, and both their instrument designs and mission operations concepts are severely constrained by data rate and volume. SpaceCube™ enables these next-generation missions.

2016 Create the Future Contest: Automotive & Transportation Category Winner

CASTROL REINVENTS THE OIL CHANGE WITH NEXCELKrishan Arora, Mike Baker, Glenn Barber, Peter Brett, Ross Dewhurst, Melvyn Dover, John Gamston, Steven Goodier, Annie Leeson, Vincent Panel, Ben Russell, Alessandra Scotese, Oliver Taylor, Julian Von Thungen-Reichenbach-Evans, Chris Wilks, John Ward-Zinski, and Roy Williamson Castrol, Oxford, UKCastrol’s NEXCEL system is a sealed oil cell that contains both the engine oil and the oil filter, so it can be easily removed and replaced by hand in about 90 seconds versus 20 minutes for a conventional oil change. The sealed cell ensures that used oil is collected and handled safely, facilitating enhanced recycling and reuse of the waste oil into high-quality lubricants through a dedicated re-refining process.
