240 boron atoms in a single molecular species
The cuboctahedron consists of copper paddle-wheel nodes and carborane–isophthalic acids Scientists in the US have made a molecular species containing the highest number of boron atoms ever recorded in a crystallographically characterised molecular species. The unique supramolecular cuboctahedron contains 240 boron atoms and was synthesised by Chad Mirkin and colleagues at Northwestern University in Evanston, Illinois, via coordination-driven… Continue reading 240 boron atoms in a single molecular species
Magnetism of single molecule controlled by voltage
The molecule of about 2 nm in size is kept stable between two metal electrodes for several days. Image: Christian Grupe/KIT A team of physicists has succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single molecule. This discovery is… Continue reading Magnetism of single molecule controlled by voltage
Even bacteria use social networks
This model shows the role of vesicles, vesicle chains and membrane tubes in M. xanthus biofilms. The scientists believe these connections help cells exchange signals and material. Image: Auer laboratory Using several imaging techniques, Lawrence Berkeley National Laboratory scientists found that a common soil bacterium stays connected by a network of chain-like membranes. They… Continue reading Even bacteria use social networks
