Artificial intelligence (AI) can become more efficient and reliable if it is made to mimic biological models. New approaches in AI research are hugely successful in experiments. Artificial intelligence has arrived in our everyday lives-from search engines to self-driving cars. This has to do with the enormous computing power that has become available in recent years.
A human research team and a machine learning algorithm have found that we need to rethink much of what we know about iridium oxide.
By Susanne Eigner Similar to batteries, supercapacitors are suitable for the repeated storage of electrical energy. TU Graz researchers have presented a particularly safe and sustainable variant of such a supercapacitor in Nature Communications. Additional at the end of the text Limited safety, sustainability and recyclability are key drawbacks of today's lithium-ion battery technology, along with restricted availability of starting materials (e.g.

By Susanne Eigner Researchers from TU Graz and Ruhr University Bochum show in the journal ACS Catalysis how the catalytic activity of cyanobacteria, also known as blue-green algae, can be significantly increased. This brings biotechnological and thus eco-friendly application a big step closer. Cyanobacteria, despite staining water green through their special pigments, are colloquially known as "blue-green algae", and convert light energy into chemical energy particularly effectively thanks to their highly active photosynthetic cells.
By Christoph Pelzl Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step towards ecologically sustainable energy storage. Additional at the end of the text "It is ground-breaking in the field of sustainable energy storage technology," says Stefan Spirk from the Institute of Bioproducts and Paper Technology at Graz University of Technology.

By Christoph Pelzl TU Graz, ams and Silicon Austria Labs has developed a compact and energy-efficient sensor for mobile devices, which informs users in real time about the fine dust content in the air and warns them in case of elevated values. Additional at the end of the text It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices.
"During its expansion, the universe evolved towards its present state, which is homogeneous and isotropic on large scales. This is inferred, among other things, from the measurement of the so-called background radiation as nicely seen in the full sky image of the WMAP data.
Electrochemical reactions, which will play an important role in the future of energy supply, can now be explained in detail, thanks to measurements carried out by TU Wien and DESY. 1/4 images The elektrochemistry team at TU Wien: Andreas Nenning, Harald Summerer, Alexander Opitz (left to right) (Copyright: TU Wien) 1/4 images The elektrochemistry team at TU Wien: Andreas Nenning, Harald Summerer, Alexander Opitz (left to right) (Copyright: TU Wien) 1/4 images A Perovskite thin film electrode, on a ZrO2 crystal - compared to a pen.
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
Ein ForscherInnen-Team um Sigurd Lax, Professor für Pathologie an der Johannes Kepler Universität Linz und Vorstand des Instituts für Pathologie des Landeskrankenhauses Graz II hat gemeinsam mit Kollegen der Medizinischen Universität Graz und der Medizinischen Universität Wien eine Studie zur postmortalen Virendynamik von SARS-CoV-2 veröffentlicht.

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.
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.
By Christoph Pelzl 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.
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.
