Lithium-ion batteries are an indispensable part of our daily lives. The negative electrodes are typically based on graphite. However, they have some problems, such as the so-called lithium plating. Now there is an electrode material that is not based on graphite and does not show these disadvantages: sodium hexatitanate.
Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyze the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure.

Fans of crime stories know: If the dentition of an unknown victim can be compared with a tooth scheme, the identity is soon clarified with this information. Similarly, the paleontologist study teeth as they contain a lot of essential biological information, representing a kind of “black box” of the life of a past individual. However, these information are not so easy to extract.
The efficiency of gas turbines is close to the limit. The state-of-the-art nickel base alloys would not tolerate higher temperatures.

In the journal Science, a Chinese–German team of researchers has presented a novel synthetic antiferromagnetic material which may prove pioneering for progress in nanomedicine and information technology. Up until now, synthetic antiferromagnets have been manufactured primarily from transition metals and alloys. The scientists from the University of Science and Technology of China in Hefei manufactured a different kind of antiferromagnet consisting of several oxide layers only a few nanometres thick, whose properties can be adapted to various applications in a targeted manner. In collaboration with Forschungszentrum Jülich, the researchers used neutron measurements at Heinz Maier-Leibnitz Zentrum (MLZ) to show that the individual layers of the new material can be magnetized and their polarity reversed – meaning that the magnetic states can be switched in a controlled fashion.

Restorers often have to deal with negative or even damaging consequences of conservation measures from earlier years. The church of St. Laurentius in Tönning / Schleswig-Holstein was also affected, because two valuable wooden figures from the beginning of the 18th century were distorted by an earlier treatment of wood preservatives.
The MLZ does not only provide excellent scientific results and user service but also extraordinary education and training for young people, world-class instruments and their upgrades. The MLZ also offers from time to time support for the technical program of the International Atomic Energy Agency (IAEA), which brings together research institutions and scientists from its different member states to collaborate on research projects or training purposes. Another important support is to fund travel expenses for scientists, as many countries only have a limited budget for research activities or travels to conferences and training.

The speed of microelectronics is currently limited by heating, as increased speed also increases the power dissipation. Spintronics or Spin-Electronics is a new concept allowing for much higher speed. It is based on the manipulation of the electron spins in magnetic layers buried inside the devices. A high magnetization of these magnetic layers is desirable in spintronic devices to allow for efficient manipulation of the electronic states.

Project partners include research institutes as well as industry leaders from five countries, with TUM as the only university.
Scientific pictures often show fantastic motifs – for scientists sometimes not so easy to recognize. For laymen, who do not know the background or genesis, and therefore look at them with a very different look, they reveal a very special beauty that can compete with classical art.
