From Japanese basket weaving art to nanotechnology with ion beams: Ultradense arrays of magnetic quanta in high-temperature superconductors

The properties of high-temperature superconductors can be tailored by the introduction of artificial defects. An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world’s densest complex nano arrays for anchoring flux quanta, the fluxons. This was achieved by irradiating the superconductor…

A closed cage-like molecule that can be opened

Molecular cages offer the possibility to encapsulate ions or other molecules. If the cage structure has a ‘hatch’ that can be opened or closed in a controllable way, it can operate as a molecular gate. Now, Shigehisa Akine from Kanazawa University and coworkers have designed a new type of molecular…
