Cubes

In their new paper, János Török and his colleagues provide support for the ancient idea of Plato that on Earth, "everything is built up from cubes". Also covered by index.hu.

Material for future devices

Material for future batteries and spintronic devices
 
Lithium shortage is an arising challenge due to the ever-increasing demand for lithium-ion based batteries. The problem could be solved by replacing lithium with sodium, which is a lot more abundant on Earth. However, until now, no one has managed to dope graphite -- which is the most common electrode in batteries -- with sodium in large enough concentrations. The researchers of the Spin-spectroscopy group of the Institute of Physics report the successful synthesis of highly sodium-doped graphene. The result was achieved in an international collaboration, and published by ACS Nano:

Ultralong Spin Lifetime in Light Alkali Atom Doped Graphene
 
The spin lifetime of electrons is also very long in this material, thus making it a good candidate for future spintronic devices. The publication was also highlighted by news site of the collaborating partner, the Swiss Federal Institute of Technology in Lausanne (EPFL). EPFL has a long-standing and fruitful collaboration with BME, and according to the latest QS World University Rankings, is the world's 14th best university.
