The Max Planck Society and the Technical University in Munich inaugurate a unique neutron spectrometer at the research neutron source (FRM-II)
N-REX+ (Neutron Reflectometry & X-Rays) is one of two neutron spectrometers that are unique worldwide; the other one is TRISP (Triple Axis Resonance Spin echo Spectrometer), already in service at the research neutron source. Both were designed and built at the high flux neutron source by Max Planck researchers over the past five years. They cost several millions of euros. From these high-tech measurement devices, scientists expect to gather new findings about nanomaterials -- particularly concerning the microscopic mechanisms behind high temperature superconductivity and the atomic processes at the inner interfaces of artificial multilayers and thin films. Both neutron spectrometers constitute the centre of work in the inter-institutional research initiative "Material and Solid State Research with Neutrons". The Max Planck Institutes for Metals Research and for Solid State Research are co-ordinating the initiative, and the Max Planck Society will be presenting it at the same time as N-REX+´s inauguration.
New technologies require scientists to develop brand-new materials, and also understand their characteristics and functions at microscopic and nanoscopic levels. Material structures are becoming increasingly small and complex, all the way to atomic dimensions. This is true for materials and material combinations of all different classes --from metals, semiconductors, and ceramics, to organic and biological materials. In order to manipulate the operations of these kind of complex systems, the scientists first need detailed knowledge of their chemical, electronic, and magnetic structures. Neutrons play a key role in this, as the "spies of the nanoworld".

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
