Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures. A research group led by Prof. Dr. Markus Retsch at the University of Bayreuth has produced colloidal crystals mimicking such structures, which are suitable for constructing new types of sensors. These sensors visibly and continuously document the temperature in their environment during a defined period. They are, therefore, tailor-made for a permanent monitoring of temperature-sensitive processes. The scientists have presented their discovery in the journal "Advanced Materials".
Using a sensor film to monitor how well aircraft and spacecraft withstand the mechanical stresses of flight: Würzburg researchers have received a prize for this idea, which comes with a lot of money.
A new type of atomic sensor made of boron nitride is presented by researchers in "Nature Communications". The sensor is based on a qubit in the crystal lattice and is superior to comparable sensors.
The research team of the Faculty of Mechanical Engineering at Landshut University of Applied Sciences and Spiess Motorenbau GmbH is developing a new method to measure heat flows in combustion engines more quickly than before; a technique which is also relevant to the research into alternative fuels and fuels that contain hydrogen
Hof/Münchberg, June 23, 2021 - Energy storage is one of the key issues for a sustainable energy supply in the future. Thousands of researchers around the world are currently working on this issue. An exciting project is also currently underway at the Münchberg campus of Hof University of Applied Sciences. Here, new types of ice batteries for cooling applications are being researched, which can help to sustainably reduce energy and CO2. They are powered by surplus solar energy.
The engineering sciences at the University of Bayreuth recently acquired a unique laser device equipped with an ultra-short pulse laser source for material processing. In the fields of gas sensor technology, high-frequency technology, and microsystems technology, the device opens up unimagined research possibilities. It can structure layers and coatings on sensitive surfaces with great precision. Hardened or fired technical substrates of all kinds can be precisely cut or milled. The device costed almost € 400,000. The German Research Foundation (DFG) provided 50 per cent of the funding for the purchase of the device at the Functional Materials research group.
Professor Dr.-Ing. Stephan Tremmel, Chair of Design & CAD at the University of Bayreuth, has received the "Future Technology Award" from the Schaeffler FAG Foundation for an innovative research idea in the field of rolling bearing technology. The award is worth € 100,000 and has been bestowed by the foundation for the first time this year.
The use of large quantities of fertilisers is leading to increasing nitrate contamination of arable land worldwide. At the same time, however, there is no method currently available with which soil nitrate content can be measured continuously over a larger area. A new research project at the University of Bayreuth headed by Prof. Dr.-Ing. Gerhard Fischerauer is determined to change that. Based on electrical impedance spectroscopy, a technique is to be developed that enables large-scale nitrate measurement in agricultural fields. The Volkswagen Foundation is funding the project for up to two years from its "Experiment!" programme.
Geothermal energy as a sustainable energy source can make its own significant contribution to reducing CO₂ emissions in Germany. This is shown by a case study of the Kirchstockach power plant published by scientists at the Center for Energy Technology (ZET) at the University of Bayreuth in the journal "Renewable Energy". Geothermal research at ZET is integrated into the Geothermal-Alliance Bavaria, which has been funded by the Bavarian Ministry of Science since 2016. Within the framework of the recently launched second funding phase, ZET will receive around 500,000 euros.
Reflexes protect our bodies – for example when we pull our hand back from a hot stove. These protective mechanisms could also be useful for robots. In this interview, Prof. Sami Haddadin and Johannes Kühn of the Munich School of Robotics and Machine Intelligence (MSRM) of the Technical University of Munich (TUM) explain why giving test subjects a “slap on the hand” could lay the foundations for the robots of the future
