Energy harvesting technology is applied to "harvest" electrical energy from dumped energy sources around us, such as vibration, heat, light, and so on. A device that is capable of harvesting energy ...

FDA-approved iron oxide nanocrystals (IONs) as negative magnetic resonance imaging (MRI) contrast agents are encountering challenges because of its low relaxation rate and coherent ferromagnetism.

"Previous analytical models treated frequency resonance as the main mechanism behind the emergence of complex orbits," says Lin. "But this approach couldn't account for the bifurcation of quasi-halo ...

Korean researchers have developed an energy harvester that can generate electric power from ambient vibrations with diverse frequencies through a novel automatic resonance tuning mechanism. It was ...
