Uni Graz beim ersten Molekül-Rennen der Welt am Start

Ein Nano-Auto, nur ein bis zwei Millionstel Millimeter groß, bewältigt einen kurvenreichen Parcours auf einer zehn mal zehn Nanometer kleinen Gold-Oberfläche: Dieser Herausforderung stellt sich Physiker Univ.-Prof. Dr. Leonhard Grill vom Institut für Chemie der Uni Graz mit seinem Team. Die ForscherInnen starten beim weltweit ersten Nano-Grand-Prix im französischen Toulouse. Ihr „Fahrzeug“ wurde von PartnerInnen der Rice University in Houston (USA) entwickelt und an der Karl-Franzens-Universität getestet.
Die molekularen Motoren, die bei diesem Rennen im Einsatz sein werden, könnten in ferner Zukunft für vielfältige Anwendungen genutzt werden: „Sie könnten beispielsweise Oberflächen reinigen, Drähte bauen, oder es ließen sich ganze Mini-Maschinen damit konstruieren“, weiß Grill. Derzeit befindet sich die Wissenschaft allerdings noch am Anfang. „Es ist schon äußerst schwierig, die willkürliche Bewegung der Teilchen gezielt in eine Richtung zu lenken“, so der Physiker. In der Grundlagenforschung will man verstehen, welche chemischen Prozesse ablaufen und wie gerichtete Bewegung auf der atomaren Skala überhaupt entstehen und nachgewiesen werden kann. Das sei alles andere als einfach.

Learning better: Can science experiments in group settings help children with autism?

How can pupils with autism spectrum disorder (ASD) have positive learning experiences and improve their social skills? Researchers at the University of Graz are investigating how science experiments in group settings can contribute to this. Initial results from the project, which is funded by the Austrian Science Fund FWF, show that children react differently depending on the kind of neurodiversity, but that experimentation classes with the right setting definitely have potential. "Pupils with ASD can do more than is currently expected of them in many cases," says project leader Uwe Simon.

Sustainability Award 2024 for two projects of the University of Graz

How do major international conferences reduce their carbon footprint? And what can maths lessons contribute to education for sustainable development? Two questions that were answered at the University of Graz. The corresponding projects were awarded the Sustainability Award 2024 in silver on 26 November in Vienna. This award for Austria's universities and colleges is presented by the Ministry of Science and the Ministry of Climate Protection.

Bees under observation: University of Graz provides unprecedented insights into the hive

What is going on in the combs? How many eggs is the queen laying? How much honey is there? Autonomous robots and AI algorithms provide important data and high-resolution real-time images from inside a beehive. "As part of an international team, we have developed a game-changer technology for a new type of digitalised behavioural research," reports biologist Thomas Schmickl from the Artifical Life Lab at the University of Graz. The publication, which has just appeared as the cover story in the journal "Science Robotics", describes the wealth of information that can be obtained from this unique research facility.

Research for healthy aging: FWF funds Cluster of Excellence "MetAGE" with 18 million euros

Six researchers from the Field of Excellence "BioHealth" at the University of Graz, together with colleagues from the Medical Universities of Graz and Vienna, have acquired an FWF-funded "Cluster of Excellence". Now a newly formed center of excellence will be created under the leadership of the University of Graz. The aim is to gain a better understanding of healthy aging. The findings will flow directly into clinical research.
