A glimpse of the inner workings of thin transistors
A team of physicists at The University of Texas at Austin has had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that an essential function for computing may be possible within a space so small that it's effectively one-dimensional.In a paper published in the Proceedings of the National Academy of Sciences, the researchers describe seeing the detailed inner workings of a type ...
Automated capabilities added to schematic family
The latest addition to the Nlview automatic schematic generation family of products has been launched by Concept Engineering. NlviewJS is a schematic engine that brings automatic schematic generation, schematic viewing and automated system assembly to the web.
A glimpse of the inner workings of atomically thin transistors
With an eye to the next generation of tech gadgetry, a team of physicists at The University of Texas at Austin has had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that an essential function for computing may be possible within a space so small that it's effectively one-dimensional.In a paper published in theProceedingsof the National Academy of Sciences, the researchers des...
Resistor choppers help to slow overspeeding fans
It is always better to be safe than sorry, and this is definitely the case with braking resistors and fans. When fans are operating in a closed system, a situation may arise where one fan will over-speed the next and the DC bus voltage on their motor drives will then rise. John Mitchell, business development manager of CP Automation, reports on the case of GA Pet Food Partners in Leyland, Lancashire.
Liquid light switch could enable more powerful electronics
Researchers have built a miniature electro-optical switch which can change the spin—or angular momentum—of a liquid form of light by applying electric fields to a semiconductor device a millionth of a metre in size. Their results, reported in the journal Nature Materials, demonstrate how to bridge the gap between light and electricity, which could enable the development of ever faster and smaller electronics.
Programmable ions could aid general-purpose quantum computers
Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.To date, many research groups have created small but functional quantum computers. By combining a handful of atoms, electrons or superconducting junctions, researchers now regularly demonstrate quantum effects and run simple quantum algorithms—small programs dedicated...
The capacitive power supply that promises 99% efficiency
A patented technique using switched capacitor charge pumps to produce small, efficient power supplies and inverters could spell the end for transformer-based systems. Sally Ward-Foxton reports.
Nano-electronic circuits have superconductivity
Scientists at TU Delft, together with colleagues from the Tübingen University, have successfully created nano-electronic circuits using a recently discovered 2D superconductor.What makes this material unique is that its superconductivity can be turned on and off remotely, very much like the switching of electrical current in a transistor on a microchip.
Industrial quality welding system in a compact and portable package
A welding system that offers a sMIG (‘smart MIG’) function has been introduced, which enables users to begin MIG welding, with an extremely stable arc, just by setting metal thickness and wire diameter.
Chemically assembled transistors and circuits are a few atoms thick
In an advance that helps pave the way for next-gen electronics and computing technologies—and possibly paper-thin gadgets —scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory developed a way to chemically assemble transistors and circuits that are only a few atoms thick. What's more, their method yields functional structures at a scale large enough to begin thinking about real-world applications and c...
