Electric vehicles are catching on across the US, but they’re also catching on fire in colder regions like the Northeast and Midwest.
Lithium-ion battery fires are becoming increasingly common as electric vehicles spread, and are hard to extinguish. A new approach uses an electrolyte based on a commercial fire extinguisher.
Lithium-ion batteries power many electric cars, bikes and scooters. When they are damaged or overheated, they can ignite or explode. Four engineers explain how to handle these devices safely.
A researcher explains developments in using light rather than electrons to transmit information securely and quickly, even over long distances.
Superconductors are materials that can transmit electricity without any resistance. Researchers are getting closer to creating superconducting materials that can function in everyday life.
Semiconductor chips are electronic devices that store and process information. Today they can contain billions of microscopic switches on a chip smaller than a fingernail.
The ability to store information is central to learning and the field of artificial intelligence. Researchers have shown how a unique material shows basic learning properties similar to that of slugs.
Right now, the nation is almost entirely dependent on other countries for minerals that are used in everything from wind turbines to strike fighters and satellites.
The high cost and long lead times for building computer chip factories makes it difficult for the U.S. to reverse the steady decline of its domestic semiconductor manufacturing capacity.
