Smallest 3D transistors ever made measure a minuscule 2.5 nanometers

Michael Irving December 9, 2018

Engineers from MIT and the University of Colorado have developed a new microfabrication technique and used it to produce the smallest 3D transistors ever made, measuring about a third the size of the current leading commercial products.

Newly-discovered blue phosphorus could be the next 2D wonder material

Michael Irving October 16, 2018

For a few years scientists have predicted a fifth kind of phosphorus should be possible, but it had yet to be confirmed. Now, researchers in Germany have managed to show that blue phosphorus does exist, and mapped out its different properties.

In blue phosphorus, the atoms arrange themselves in a honeycomb pattern like graphene, but buckled, thanks ...

Sprayable antennas turn surfaces into ultra-thin, transparent transmitters

Michael Irving September 23, 2018

As crucial as antennas are, the rigid metals they’re made of can limit what devices they can be built into. To help with that, researchers at Drexel University have developed a new kind of antenna that can be sprayed onto just about any surface.

The sprayable antenna is made of MXene, a 2D titanium carbide material, which is extremely conductive ...

Midas touch virus builds gold nanobeads on demand

Michael Irving August 26, 2018

Researchers at the University of California, Riverside have found a way to use viruses to build gold nanobeads, which can then be used to purify water and could eventually help cut the cost and time required to produce electronic components.

Electronic stickers to step up Internet of Things expansion

Matt Kennedy July 19, 2018

Limiting the expansion, and ultimate ubiquity, of the Internet of Things has been the cost, power and size of the enabling electronics – all things that have been addressed by a new fabrication method for tiny, thin-film electronic circuits.

"World's smallest computer" is a sensor smaller than a grain of sand

Michael Irving June 24, 2018

"World’s smallest computer” is a contentious title, not just because scientists are racing to shrink devices, but because the very definition of a computer could be up for debate. The latest claim to the title is a tiny device that communicates through light and makes a grain of rice look gigantic.

Nanofilm recycles electronic waste heat as electricity

Michael Irving April 16, 2018

Waste heat generated by electronics can damage components, and represents a large amount of energy going to waste. Now scientists at the UCB have developed a thin film that could be built into computers, cars or factories to capture and recycle the energy from waste heat.

Meet gallenene: Gallium joins graphene in the second dimension

Michael Irving March 12, 2018

Graphene hogs all the headlines about two-dimensional materials, but it might just be the beginning. Researchers have now isolated a 2D form of the soft metal gallium, dubbed "gallenene," which could make for efficient, thin metal contacts in electronic devices.

Transistor breakthrough brings liquid computers closer to reality

David Szondy November 6, 2017

In a step towards creating a new class of electronics that look and feel like soft, natural organisms, mechanical engineers at Carnegie Mellon University are developing a fluidic transistor out of a metal alloy of indium and gallium that is liquid at room temperature.

Liquid at room temperature, an indium gallium alloy can be used to create stretchable circuit wiring ...
