Eco-friendly flying is on the horizon. All over the world, researchers are developing new technologies to achieve this goal. One focus of developments is the idea of using hydrogen-powered engines for aircraft in the future. The aircraft companies, though, face the challenge of storing this energy source. Hydrogen turns liquid when cooled to minus 253 degrees Celsius, and only then can it be used as a so-called cryogenic fuel. Both tanks and pipe systems in the aircraft have to be absolutely tight at such low temperatures. An innovative new welding process can help to fulfill these requirement: magnetic pulse welding. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have now demonstrated that this joining technology can produce extremely resilient, metallic mixed joints for cryogenic applications. They successfully achieved these outstanding joint properties in cooperation with the Technical University of Munich.
When a rocket is launched, the weld seams on the enormous fuel tanks must withstand immense forces. To produce joints with the necessary strength, a process known as “friction stir welding” is used.

Physics can also taste very sweet – this is one of the things that the pupils from grade 3 of the elementary school Garching Ost learned during their visit at the Research Neutron Source Heinz Maier-Leibnitz. They made an atom model from toothpicks and marsh mallows and tried their abilities as neutron scatterers at a neutron ball toss.
An international research team has discovered the mechanism by which a pharmaceutical excipient from the class of block copolymers improves the solubility of large quantities of a poorly water-soluble active substance. The results form the basis for the development of a drug delivery system better tolerated by the human body.
For her doctoral thesis “Thermal Conductivity of High Density Uranium-Molybdenum Fuels for Research Reactors” Dr. Tanja Huber is awarded the Karl Wirtz Prize of the German Nuclear Society (KTG) today.
A key issue with lithium ion batteries is aging. It significantly reduces their potential storage capacity. To date, very little is known about the causes of the aging effects. Scientists from the Department of Technical Electrochemistry and the Research Neutron Source FRM II at the Technical University of Munich (TUM) have now come a step closer to identifying the causes in their latest experiments.
Usually, harvesting energy and raw materials from plants requires many process steps and aggressive chemicals. To make these processes more efficient and resource saving, researchers are looking for suitable enzymes. Using neutrons, researchers have now investigated the reaction mechanism of an important class of enzymes – the glycosidases. The measurements were made at the neutron sources in Los Alamos and Oak Ridge (USA), as well as at the research neutron source FRM II of the Technical University of Munich (TUM). The results provide the key to improving large-scale technical processing of biomass.
How mobile individual polymers are reveals a lot about their macroscopic properties. Neutron researchers at Forschungszentrum Jülich have now found a much easier and more accurate way of investigating the often decisive lateral deflection of molecules. They use ring-shaped molecules as probes, which wrap themselves around the polymer chains and follow their lateral motion.
Today a new cooperation project starts, which is headed by MLZ partner JCNS: CREMLIN (Connecting Russian and European Measures for Large-scale Research Infrastructures) shall promote the EU-Russia cooperation in the planning, construction and scientific use of large scale facilities.
New Study shows Correlation between Microscopic Structures and Macroscopic Properties
The scientists were able to detect structural changes using a model system of phospholipids from soy plants with the help of neutron scattering techniques at the Heinz Maier-Leibnitz Zentrum in Garching near Munich.
Measurements at the three axes spectrometer PUMA have now been published in the renowned journal Nature Communications.
Measurements using positrons could help to develop better coatings for drugs.
Lithium-ion batteries are seen as a solution for energy storage of the future and have become indispensible, especially in electromobility. Their key advantage is that they are able to store large amounts of energy but are still comparatively light and compact.
Neutron scattering experiment at PUMA resolves a contentious superconducting issue.
Neutrons shed light on vital enzymes’ mechanism of action
In the future, antineutrino detectors may provide an additional option for monitoring. Physicists at Technische Universitaet Muenchen (TUM) have now found interesting results using fast neutrons from the Heinz Maier Leibnitz Zentrum.
Experiments with neutrons at the Technische Universität München (TUM) show that the antidepressant lithium accumulates more strongly in white matter of the brain than in grey matter.
The world’s strongest neutron beam is produced by the scientific instrument PGAA at the FRM II. But that is not all: During the long maintenance break in 2011, the PGAA (Prompt Gamma Activation Analysis) was improved to give it the best ratio between usable neutrons and noisy background radiation worldwide.
