Toward a new kind of superconductivity: new publication in the Nature Magazine
Industry and private consumers alike depend on oil and gas pipelines that stretch thousands of kilometers underwater. It is not uncommon for these pipelines to become clogged with deposits. Until now, there have been few means of identifying the formation of plugs in-situ and non-destructively. Measurements at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) at the Technical University of Munich (TUM) now show that neutrons may provide the solution of choice.
The research neutron source Hein Maier-Leibnitz (FRM II) at the Technical University of Munich (TUM) is playing an important role in the investigation of mRNA nanoparticles similar to the ones used in the Covid-19 vaccines from vendors BioNTech and Pfizer. Researchers at the Heinz Maier-Leibnitz Zentrum (MLZ) used the high neutron flux available in Garching to characterize various formulations for the mRNA vaccine and thus to lay the groundwork for improving the vaccine's efficacy.
While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the Max Planck Institute for Solid State Research in Stuttgart have now made an important advance in the development of novel materials for such components. These materials may also be the key to quantum computers that are less susceptible to interference.
The development of a topological laser network by a team of the Cluster of Excellence ct.qmat is among the top ten nominations for the "Breakthrough of the Year Award“.
More and more studies worldwide are looking into the effects of microplastics, especially with regard to the environment and health. They often use spherical polystyrene microparticles and have arrived at partly contradictory results. An interdisciplinary research team at the University of Bayreuth has discovered a reason for this. Commercially available, supposedly identical polystyrene particles differ significantly, depending on the manufacturer, in terms of their structure and properties. Therefore, their interactions with living cells have different consequences for cell metabolism. The scientists have presented their study in the Journal of Hazardous Materials.
The German Research Foundation (DFG) recently announced that the Collaborative Research Center "From the Fundamentals of Biofabrication to Functional Tissue Models" (SFB-TRR 225) will be funded for another four years. In this research network, the University of Bayreuth cooperates with the Friedrich Alexander University of Erlangen-Nuremberg and the University of Würzburg. The spokesperson for the Bayreuth site is Prof. Dr. Thomas Scheibel, Chair of Biomaterials. Working groups at the three partner universities are jointly researching the fundamentals of biofabrication with the long-term goal of producing functional tissue models for novel and pioneering biomedical applications.
While the number of qubits and the stability of quantum states are still limiting current quantum computing devices, there are questions where these processors are already able to leverage their enormous computing power. In collaboration with the Google Quantum AI team scientists from the Technical University of Munich (TUM) and the University of Nottingham used a quantum processor to simulate the ground state of a so-called toric code Hamiltonian – an archetypical model system in modern condensed matter physics, which was originally proposed in the context of quantum error correction.
Researchers at the University of Bayreuth, together with partners in China and the USA, have for the first time produced a carbon material that does not have the strictly ordered structures of a crystal, but is not amorphous either. It is paracrystalline diamond with unique optical, mechanical and thermophysical properties. The material offers important clues for understanding non-crystalline materials as well as for the targeted synthesis of other new carbon materials. The international team presents its discovery in Nature.
In the "Research Factory Battery" cluster network of the Federal Ministry of Education and Research (BMBF), the University of Bayreuth is now also involved in the "Solid State Batteries - FestBatt" cluster of competence. A new research project coordinated from Bayreuth aims to significantly increase the energy density of rechargeable all solid-state batteries and make the production of these batteries more sustainable. To this end, the powder aerosol deposition (PAD) method is a promising process to be used in future for the coating of cathodes and solid electrolytes. Research partners are Saarland University and the Karlsruhe Institute of Technology.
