Silicon has been the material of choice for electronics for decades, but it’s beginning to bump up against efficiency limits. Now engineers at UC Berkeley have created metallic graphene nanoribbons, which can make wires for all-carbon electronics.

Researchers have developed a kind of electronic “invisible ink” that can alert users to unauthorized tampering with a device. When the chip is exposed to light it will erase information printed on it, making it clear that someone’s opened the box.

Engineers have developed a simple way to make colloidal diamonds that self-assemble. These structures have traditionally been tricky to manufacture in bulk, but with this new method they could be used to help make better photonic devices.

Face masks are here to stay for a while yet – so you might as well have some fun with them. The JabberMask is a voice-activated wearable packed with LEDs that move like a mouth in time with your speech, and can smile or display emojis on demand.

Electromagnetic shielding is usually placed around electronics to prevent interference. Now, engineers have found that a 2D material called titanium carbonitride is excellent at the job, absorbing rather than reflecting electromagnetic waves.

Perovskite is emerging as a promising material for solar cells, but it has some durability problems. Now, engineers have developed a new electrode that could make them more stable, using a protective layer of "graphene armor."

Graphene may be a versatile material, but it remains tricky to produce in large amounts. Now, an MIT team has found a new way to make large sheets of graphene in a roll-to-roll process, by depositing it onto a substrate that can easily be peeled off.

Graphene is ultrathin, ultra-strong and has some weird electrical properties. MIT researchers previously found a strange pattern emerged in “twisted” graphene structures. Now they’ve studied it more closely and found it works better with more layers.

Graphene is already known for being incredibly strong, so how can it be made even stronger? By turning it into sheets of diamond, of course. Researchers in South Korea have developed a new method to convert graphene into ultrathin diamond films.

Researchers from Johns Hopkins University have found a superconducting material naturally stable in two states at once, which is useful for quantum computers.

Researchers have developed a new way to weld ceramics together at room temperature, using ultrafast laser pulses.

Organ development has traditionally been tricky to study, thanks largely to the difficulty in getting sensors in there without damaging the organs. Now, researchers from Harvard have developed a way to create “cyborg organoids” by integrating nanoelectronics into cell cultures.
