Reducing energy consumption caused by cooling systems and reducing plastic waste in the environment are key requirements for a sustainable economy. In a research project on novel functional films, Bayreuth-based physical chemist Prof. Dr. Markus Retsch aims to tackle both problems simultaneously: In the future, plastic waste is to be processed into large-area films that can cool without the need to supply energy from outside. The project is funded by the Proof of Concept Grants programme of the European Research Council (ERC) with around 150,000 euros.
Prof. Dr. Anna Köhler, Chair of Soft Matter Optoelectronics at the University of Bayreuth, has been elected as a new full member of the Bavarian Academy of Sciences and Humanities (BAdW). She was recently officially welcomed in Munich as a new member of Section III "Natural Sciences, Mathematics, Engineering". The Bayreuth experimental physicist is only the fourth researcher to be admitted to this 58-member BAdW section.
Jules Verne could not even dream of this: A research team from the University of Bayreuth, together with international partners, has pushed the boundaries of high-pressure and high-temperature research into cosmic dimensions. For the first time, they have succeeded in generating and simultaneously analyzing materials under compression pressures of more than one terapascal (1,000 gigapascals). Such extremely high pressures prevail, for example, at the center of the planet Uranus; they are more than three times higher than the pressure at the center of the Earth. In Nature, the researchers present the method they have developed for the synthesis and structural analysis of novel materials.
When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super hot explosion and produce a fireball of X-ray radiation. A research team led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now been able to observe such an explosion of X-ray light for the very first time.
Simulating complex scientific models on the computer or processing large volumes of data such as editing video material takes considerable computing power and time. Researchers from the Chair of Laser Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and a team from the University of Rochester in New York have demonstrated how the speed of fundamental computing operations could be increased in future to up to a million times faster using laser pulses. Their findings have now been published in the journal Nature.
Dr. Danilo Di Genova from the Bavarian Research Institute of Experimental Geochemistry & Geophysics (BGI) at the University of Bayreuth has been awarded an ERC Consolidator Grant by the European Research Council. His NANOVOLC project will receive funding of around two million euros over the next five years. It investigates magma viscosity, which is of great relevance for assessing hazards that may emerge from active volcanoes around the world.
Stable packets of light waves – called optical solitons – are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers at the Universities of Bayreuth and Wrocław have now solved the puzzle of how these temporal links are formed. They report on their discovery in Nature Communications. The dynamics of the coupled light packets can be used to measure atomic vibrations as characteristic "fingerprints" of materials in an extremely fast manner.
The game app " Kitty Q - a Quantum Adventure", the joint project of the Cluster of Excellence ct.qmat of the Universities of Würzburg and Dresden and the game designer Philipp Stollenmayer, has been awarded "Best Mobile Indie Game" at the Valencia Indie Summit. In addition, the mobile game with the cute, half-dead kitty Q has been nominated for other prestigious German media awards: for the GOLDEN SPATZ in the "Digital" competition and for the DEUTSCHE COMPUTERSPIELPREIS (DCP) as "Best Family Game". The DCP awards gala takes place tonight starting at 7:30 p.m. and is live streamed.
Nuclear medicine utilizes technetium-99m among other things for tumor diagnostics. With over 30 million applications worldwide each year, it is the most widely used radioisotope. The precursor material, molybdenum-99, is mainly produced in research reactors. A study at the Heinz Maier-Leibnitz Research Neutron Source (FRM II) at the Technical University of Munich (TUM) now illustrates options to significantly reduce the radioactive waste produced during processing to a medical product.
Physicists at the University of Bayreuth are among the international pioneers of power functional theory. This new approach makes it possible for the first time to precisely describe the dynamics of many-particle systems over time. The particles can be atoms, molecules or larger particles invisible to humans. The new theory generalizes the classical density functional theory, which only applies to many-particle systems in thermal equilibrium. In the "Reviews of Modern Physics", a research team led by Prof. Dr. Matthias Schmidt presents the basic features of the theory, which was significantly developed and elaborated in Bayreuth.
