Janus particles under the electron microscope. The titanium dioxide microswimmers are barely larger than one micrometer. Copyright: Simmchen Group TU Dresden Freigeist fellow Dr Juliane Simmchen is investigating with her multidisciplinary junior research group the motion of synthetic microswimmers in liquids. Her goal is to enable these inanimate microparticles to […]

Reconstructed vortex rings inside a magnetic micropillar. Credit: Claire Donnelly The first experimental observation of three-dimensional magnetic ‘vortex rings’ provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices. Magnets often harbor hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is […]
