Recent technological advances have opened new possibilities for the development of advanced medical devices, including tiny ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...

While the magnetic dipoles are all the same magnitude, the direction of the dipoles can be controlled so that when driven by a rotating magnetic field, particles spin around, bump into each other and ...

From DIY levitation tricks to clever braking systems, these swirling paths of electrons keep finding new ways to surprise and inspire.
