Superconducting materials are similar to the carpool lane in a congested interstate. Like commuters who ride together, ...

If electric vehicles were lighter, they would also be more energy-efficient. Not surprisingly, this is a problem researchers ...

Chemistry World welcomes letters, which should be concise (normally fewer than 300 words) and timely. Those selected for publication are subject to editing for clarity and length. Letters should be ...

Tunable lasing at around 405 nm is realised with an InGaN device featuring a narrow-ridge active channel and a periodically ...

The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in ...

By twisting layers of graphene, researchers discovered a unique electronic crystal where electrons freeze in place yet allow ...

We present a fully quantum model for the excitation of a bound electron based on the “free-electron bound ... of the analytical model at its validity ranges using a fully quantum density matrix ...

Quantum spin liquids are fascinating states of matter where magnetic spins stay disordered, defying the usual rules of magnetism. Scientists have made an exciting discovery about one such material.

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

The highest flux density occurs when the conductor is formed into a coil ... Current is a flow of charge. Each electron carries a charge of 1.6 × 10-19 coulombs. This is far too small to be any use, ...
