Chill out: Advanced solar tech runs cooler and lasts longer

New mechanisms for converting sunlight to electricity more efficiently are also beneficial for extending the lifespan of solar panels.

In graphene process, resistance is useful

Scientists adapt laser-induced graphene to make conductive patterns from standard photoresist material for consumer electronics and other applications.

Towards 2D memory technology by magnetic graphene

In spintronics, the magnetic moment of electrons is used to transfer and manipulate information. An ultra-compact 2D spin-logic circuitry could be built from 2D materials that can transport the spin information over long distances and provide strong spin-polarization of charge current. Experiments by physicists suggest that magnetic graphene can be the ultimate choice for these 2D spin-logic devices as it efficiently converts charge to spin current and can transfer this strong spin-polarization over long distances.

Physicists find a novel way to switch antiferromagnetism on and off

Physicists have found a novel way to switch antiferromagnetism on and off, which could lead to faster, more secure memory storage.

An uncrackable combination of invisible ink and artificial intelligence

Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

Thin, large-area device converts infrared light into images

An infrared imager developed by engineers could be used to see through smog and fog; easily locate blood vessels on a patient; and see through silicon wafers to inspect the quality of electronic boards. It is also slim, compact and less costly to fabricate than similar technologies.

New graphite-based sensor technology for wearable medical devices

Researchers have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team's printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility.
