In a very unusual way, the electrical and magnetic properties of a particular crystal are linked together - the phenomenon was discovered and explained at TU Wien (Vienna). Electricity and magnetism are closely related: Power lines generate a magnetic field, rotating magnets in a generator produce electricity.
Several minerals suffer radioactive self-irradiation and hence experience long-term changes of their properties. The mineral monazite virtually behaves "just alike Camembert cheese in which holes are drilled": Existing radiation damage heals itself. An international research team led by Lutz Nasdala, Institute of Mineralogy and Crystallography, University of Vienna, conducted an ion-irradiation study that has unravelled the causes of the self-healing of monazite.
Biofabrication includes upcycling of low-cost agricultural and forestry by-products Leather is used as a durable and flexible material in many aspects of everyday life including furniture and clothing. Leather substitutes derived from fungi are considered to be an ethical and environmentally friendly alternative to traditional bovine leather.
COVID-19: Virale RNA auch mehrere Tage nach dem Tod noch vorhanden

Why do different measurements of material properties sometimes give different results? A research team led by the TU Vienna has now found an important answer. It is very hard to take a photo of a hummingbird flapping its wings 50 times per second. The exposure time has to be much shorter than the characteristic time scale of the wing beat, otherwise you will only see a colorful blur.
Scientists reveal key steps in the formation of the recycling cen-ters of the cell Autophagy, from the Greek for 'self-eating', is an essential process that isolates and recycles cellular components under conditions of stress or when resources are limited. Cargoes such as misfolded proteins or damaged organelles are captured in a double membrane-bound com-partment called the autophagosome and targeted for degradation.
International research team describes the new possibilities offered by the use of ultracold dipolar atoms The quantum properties underlying crystal formation can be replicated and investigated with the help of ultracold atoms. A team led by Dr. Axel U. J. Lode from the University of Freiburg's Institute of Physics has now described in the journal Physical Review Letters how the use of dipolar atoms enables even the realization and precise measurement of structures that have not yet been observed in any material.
Joint investigations by researchers from Graz University of Technology and the ÖAMTC show that the risk of serious head injuries increases when an already damaged helmet or a wrong helmet is worn.

Threatened with extinction despite perfect adaptation Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape.
Simulations at Graz University of Technology refute earlier theories on long-range charge transfer between organic and inorganic materials. Oliver Hofmann and his research group at the Institute of Solid State Physics at TU Graz are working on the optimization of modern electronics. A key role in their research is played by interface properties of hybrid materials consisting of organic and inorganic components, which are used, for example, in OLED displays or organic solar cells.
How can you perforate an atomic layer of material and leave the one underneath intact? Scientists at TU Wien (Vienna) developed a technique for processing surfaces on an atomic scale. Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact.
"Core-shell" clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient. Additional images for download can be found at the end of the message Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles - smallest portions of bulk material - form the basis for a whole range of new technological developments.
Soils play a major role when it comes to the long-term storage of CO2 and the resulting reduction of this gas in the atmosphere - therefore they can contribute to slowing down climate change. In order to gain a better understanding of these mechanisms, it can be helpful to look at the microscopic level of soil microorganisms.
Researchers at TU Graz and AVL focus on software systems of autonomous driving systems. They developed a method for generating safety-critical simulation scenarios and an adaptive control procedure for compensating for internal errors.

A major international research project led by TU Wien (Vienna) shows for the first time that flooding characteristics in recent decades are unlike those of previous centuries Overflowing rivers can cause enormous problems: Worldwide, the annual damage caused by river floods is estimated at over 100 billion dollars - and it continues to rise.
The new machine is intended to facilitate industrial composting and makes autonomous driving acceptable for chain-driven machines as well. Turning and mixing large compost heaps are important steps in composting to speed up the rotting process. Composting plants and agricultural businesses use mostly tractor-drawn turners or a diesel-powered compost turner with crawler track.
For a long time, something important has been neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials. Ever smaller and ever more compact - this is the direction in which computer chips are developing, driven by industry. This is why so-called 2D materials are considered to be the great hope: they are as thin as a material can possibly be, in extreme cases they consist of only one single layer of atoms.
To fully exploit the potential of the "wonder material" graphene, it has to be combined with other materials. A new study investigates what is important for this. Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical and optical properties have made graphene one of the most studied materials at the moment.
Milestone for therapeutic development of peptides against gastrointestinal disorders The fascinating family of trefoil factor peptides brings hope to both research and industry to improve the treatment of chronic disorders such as Crohn's disease. For the first time, a team led by ERC awardee Markus Muttenthaler from the Faculty of Chemistry of the University of Vienna succeeded in the synthesis and folding of the peptide TFF1, a key player in mucosal protection and repair.
An international team of scientists from Austria, Germany and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10-15 km/s. This opens access to investigations of the rich physics of non-equilibrium collective systems and renders a direct-write Nb-C superconductor as a candidate material for single-photon detectors.
