Feldemissionsmikrosonde stärkt Forschungen am NAWI Graz Geozentrum: Sie schafft hochauflösende Aufnahmen im Nanobereich

Viel ist von außen nicht zu erkennen, aber das Gerät hat es in sich: Die neue Feldemissionsmikrosonde am Institut für Erdwissenschaften kann Aufnahmen im Nanobereich anfertigen – und das bei einer sehr hohen Auflösung. „Die modernen Geowissenschaften haben sich in den letzten Jahrzehnten von einer beschreibenden zu einer quantitativen Naturwissenschaft gewandelt“, erklärt dazu Christoph Hauzenberger, Leiter des Bereichs Petrologie und Geochemie. Wichtige Fortschritte bei der technischen Entwicklung gab es bei der räumlich hochauflösenden Analyse von Elementen. So eröffnen sich vollkommen neue Arbeitsgebiete in den Geowissenschaften, Physik, Chemie, in der Archäologie/Archäometrie oder auch in den Materialwissenschaften. Der Betrieb einer Feldemissionsmikrosonde am Wissenschafts-Standort Graz ist daher eine zukunftsträchtige Erweiterung für das bestehen NAWI Graz Central Lab für Water, Minerals and Rocks. In der Steiermark ist diese Sonde einzigartig, vergleichbare Geräte gibt es in Wien.

Mit rund 1,2 Millionen Euro wurde die Feldemissionsmikrosonde aus Geldern von NAWI Graz, dem Institut und Hochschulraumstrukturmitteln finanziert. Feierlich in Betrieb genommen wurde sie am 23. Jänner 2019 im Beisein von Vizerektorin Renate Dworczak, NAWI Graz Dekan der TU Graz, Gerald Zenz sowie dem Institutsleiter der Erdwissenschaften, Steffen Birk.

Jurassic Sounds: Biologist reconstructs insect songs from 165 million years ago

It was apparently not just the roars of the dinosaurs that made up the soundscape of the animal world during the Jurassic period. Crickets and grasshoppers communicated through a variety of songs and high-pitched sounds, as Thorin Jonsson from the Institute of Biology at the University of Graz discovered together with colleagues from the universities of Lincoln, Bristol (UK), Beijing (China) and Tempe (USA). The findings on what are so far the oldest traces of sound on Earth have just been published in the journal PNAS.

EU funding boosts international exchange between universities

The University of Graz is further expanding its international study opportunities through the European university alliance Arqus and is taking the lead in two key projects. In future, students will benefit from even more joint degree programmes and from simplified recognition of academic achievements through the Joint European Degree Label.

Rescue and risks: Researchers have surveyed public perceptions of AI

The use of artificial intelligence has had to be made transparent since 2 August 2026. The EU’s AI Act, which has been in force since then, also sets out how risky an application is and which security measures apply as a result. However, the assessment of risks by the legislation differs in some cases significantly from the perceptions of the Austrian public. This is the finding of a representative study carried out by data scientist Stefan Thalmann from the University of Graz and his team.

The Healing Sea: Researchers discover new approaches to treating chronic inflammation in sponges

Chronic inflammation plays a key role in many diseases, ranging from metabolic disorders and cardiovascular diseases to tissue damage following injuries or infections. “Normally, the body is able to resolve inflammation on its own. If this process becomes unbalanced, immune cells remain permanently active and continue to drive negative changes in the tissue,” explains Andreas Koeberle, a pharmacist at the University of Graz.
