Wasserstoff könnte Autofahren sauberer machen – doch bislang fehlen geeignete Speichermaterialien für das Gas. Die Kandidaten für einen Wasserstofftank untersuchen Forscher am Max-Planck-Institut für Metallforschung, am Max-Planck-Institut für Kohlenforschung und am Max-Planck-Institut für Kolloid- und Grenzflächenforschung.

Die Giftklaue der Spinne Cupiennius Salei verdankt ihre biomechanischen Eigenschaften einer sehr gut angepassten Struktur. Das hat ein Team um Y. Politi vom Max-Planck-Institut für Kolloid- und Grenzflächenforschung in einer biophysikalischen Simulation an einem Modell der Klaue herausgefunden.

The demographic scaling model developed by researchers at the Max Planck Institute for Demographic Research in Rostock and University of Helsinki makes it possible to estimate the actual number of Covid-19-infections in different countries with just a minimum of data. According to this model, the number of cases in Germany is only 1.8 times higher than the number of confirmed cases. For Italy, however, the researchers estimate that the number of infected is 6 times higher than the number of confirmed cases reported by the health authorities.
If the distance between the red bar (number of confirmed

An artificial diamond containing small quantities of the heavy carbon isotope C-13 and nitrogen forming N-V centres serves as a quantum memory at room temperature. The long-term memory, which was developed by researchers including I. Cirac from the Max Planck Institute of Quantum Optics and Harvard University, stores the quantum information of a qubit in the nuclear spin of a carbon atom.
The C-13 nucleus thus behaves like a tiny bar magnet
The structure of nanoscale samples can prospectively be examined with magnetic resonance spectroscopy. Scientists from the University of Stuttgart and the Max Planck Institute for Solid State Research and F. Reinhard and J. Wrachtrup have made it possible to use a nitrogen vacancy centre, or NV centre for short, as a detector to analyse the polarisation of nuclear spins and thus examine the structure of nanoscopic samples.
Nuclear spin is what makes each atom into a tiny bar
