Janus particles, which take their name from a Roman god with two faces, are microscopic 'two-faced' spheres whose halves are physically or chemically different. Now, U.S. researchers have shown that ...

Microbots have made great strides in recent years as scientists and engineers work on creating cell-sized robots that can swim through the bloodstream and act as tiny medical commandos. However, such ...

One way or another: Janus spheres are coated with gold and platinum. (Courtesy: Vladsinger/CC BY-SA 4.0) If a micron-sized sphere is coated half in gold and half in platinum, then placed in a solution ...

(Nanowerk Spotlight) As technology advances toward flexible, adaptive devices, traditional electronics are hitting their limits due to rigidity and power demands. But what if materials themselves ...

Team successfully exerted electrical control over polaritons, hybridized light-matter particles, at room temperature. A research team consisting of Professor Kyoung-Duck Park and Hyeongwoo Lee, an ...

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 ...
