Researchers at the National High Magnetic Field Laboratory in Tallahassee, Florida, have pushed a palm-sized superconducting coil to 42 tesla, placing a device small enough to hold in one hand within ...
Researchers at ETH Zürich have built the most powerful miniature superconducting magnets ever demonstrated, ...
In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.
