Tohoku University (Japan), LPP (France), and partners has demonstrated that chorus emissions, natural electromagnetic waves ...

The hollow SiC/C nanofiber aerogel using a hydrothermal-carbothermal reduction method. ABF-STEM imaging clearly reveals the hollow structure of the SiC/C nanofibers and the abundant interfaces present ...

Abstract: The threat of high-altitude electromagnetic pulse (HEMP) to electronic information equipment has received widespread attention. Specific to the performance evaluation testing requirements of ...

Abstract: As the key component of direct drive or semi-direct drive systems, the timely detection of internal faults in permanent magnet synchronous generators (PMSGs) is crucial for ensuring the long ...

Even in crystal-clear water, it can be easy for scuba divers to lose track of which way they're heading. An experimental new underwater navigation system could help keep that from happening, using a ...

ABSTRACT: Magnetic launchers provide safer, faster, and lower-friction alternatives to traditional chemical-fuel systems by using innovative principles such as superconducting magnetic levitation, ...

Porous carbon materials with good microwave absorption properties were prepared by Friedel-Crafts reaction and high-temperature carbonization using inexpensive coal tar pitch as carbon source. Porous ...

Scientists have developed an AI-powered fluid simulation model that significantly reduces computation time while maintaining accuracy. Their approach could aid offshore power generation, ship design ...
