The ultrafast placement of an electron in a polar liquid generates collective molecular vibrations in a spherical nano-volume ...

In a striking blend of optics and acoustics, researchers at the Beijing Institute of Technology have developed a visual ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual ...

China has unveiled the world's fastest maglev train, reaching 600 km/h using superconducting magnetic levitation. Developed by CRRC Changchun and revealed at Modern Railways 2025, this next-gen train ...

In this study, a noncontact, high-precision optical heterodyne interference (OHI) measurement system is employed in a 2-D plane to measure the amplitude components of the velocity in two directions at ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

Rotor eccentricity faults can cause uneven air gaps in the generator, reducing power quality and increasing vibration noise, eventually leading to abnormal operation. Especially in high-speed machines ...
