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".

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
