Diamagnetic levitation was applied to micro-positioning and trapping of diamagnetic micron-sized particles and micro-droplets. Scale reduction laws for magnetism indicate that diamagnetism is highly ...

Magnetic Fe3O4 hollow spheres were successfully synthesized with a water in oil in water (W/O/W) emulsion. During the facile procedure, no high pressure, high temperature, or other complex reaction ...

Integrated ground coils realize combination of propulsion, levitation and guidance (PLG) functions for electrodynamic suspension (EDS) train, which is of great significance for cost-saving and ...

The sci-fi genre has as many entries as there are stars in the sky. Its many subgenres range from grounded to awe-inspiring to absurd. Hard sci-fi books read like something that could happen in ...
