What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with these materials, researchers have fabricated microsupercapacitors onto the surface of stone tiles. The devices, reported in ACS Nano, are durable and easily scaled up for customizable 3D power supplies.

It would be convenient if the surfaces in rooms could charge smart home devices or other small electronics without being connected ...

The 2.6nm-long single molecule wire has quasi-metallic properties and shows an unusual increase of conductance as the wire length increases; its excellent conductivity holds great promise for the field of molecular electronics.

As our devices get smaller and smaller, the use of molecules as the main components in electronic circuitry is becoming ever more critical. Over the past 10 years, researchers have been trying to use single molecules as conducting wires because of their small scale, distinct electronic characteristics, and high tunability...

Researchers investigate ways to make AIs more robust by studying patterns in their answers when faced with the unknown. Current AIs are very accurate but inflexible at image recognition. Exactly why this is remains a mystery. Researchers have developed a method called ‘Raw Zero-Shot’ to assess how neural networks handle elements unknown to them...

Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up in size and power. It is an achievement that means size does not have to come at the expense of coherence, enabling lasers to be more powerful and to cover longer distances for many applications.
