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.

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.

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.

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 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.

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.

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.
