Lebendige Chemie

Wasser zerfällt in seine Bestandteile: Der Nachwuchsforscher liest mit Unterstützung von Wolfgang Kroutil ab, wie viel Wasserstoff und Sauerstoff sich bilden, seine junge Kollegin notiert die Werte an der Tafel.

Wolfgang Kroutil demonstriert, was passiert, wenn Öl und Wasser aufeinandertreffen ...

... Nach dem Schütteln trennen sich Öl und Wasser wieder. Das Öl setzt sich oberhalb des mit Tinte blau gefärbten Wassers ab.

Grazer VolksschülerInnen erlebten eine spannende Experimentalvorlesung an der Uni Graz

Wasser stand am 9. April 2013 im Mittelpunkt einer Experimentalvorlesung am Institut für Chemie der Uni Graz. Das Publikum: SchülerInnen der 3. und 4. Klassen der Volksschule Graz-St. Peter.

Ao.Univ.-Prof. Dr. Wolfgang Kroutil verstand es ausgezeichnet, den Kindern zu demonstrieren, was Wasser alles kann, und ihnen damit die chemischen Eigenschaften dieses Elements auf lebendige Art und Weise näherzubringen.

Mit großem Interesse verfolgten die SchülerInnen die spannenden Versuche und waren begeistert über das eine oder andere Ergebnis, Knall und Stichflamme inklusive.

Als AssistentInnen standen Wolfgang Kroutil die Studierenden Barbara Grischek und Mag. Christoph Winkler zur Seite. Und auch auch aus dem Publikum holte sich der Chemiker Verstärkung.

Die Vorlesung wurde im Rahmen der KinderUniGraz veranstaltet und brachte somit AnwärterInnen für die KinderUni-Sponsion einen Punkt weiter auf dem Weg zu ihrem Ziel.

Talent Talks bridge the gap in career guidance

The Styrian Chamber of Commerce (WKO Steiermark), the Styrian Chamber of Labour (AK Steiermark) and the AMS are joining forces when it comes to training young people and, through the “Talent Talks”, are creating a seamless pathway to career guidance. This takes preparation and follow-up support – just in time for the start of the term and the scheme’s tenth anniversary – to a whole new level. A new survey conducted by the Talent Centre among 2,687 former participants to mark the anniversary shows just how important this development is. Of the young people who received follow-up support from the Talent Report, 74.6 per cent stated that they had a good understanding of their own strengths and talents following the Talent Check. Without follow-up support, the figure was 66.5 per cent – a significant difference of 8.1 percentage points.

Austria’s emissions rose in 2025: University of Graz researchers analyse the causes

The Environment Agency Austria has today published the figures for the country’s greenhouse gas emissions in 2025. While emissions fell sharply year on year from 2022 to 2024, they rose again by just under 0.7 per cent in 2025. Researchers at the University of Graz have analysed how much of this increase was due to structural changes in the economy and how much was attributable to external factors over which there is little control. “In 2025, the colder winter compared with 2024 increased emissions by 0.81 per cent, while the weak economy reduced them by 0.38 per cent. If we factor out these influences, we find an underlying increase of 0.26 per cent compared with the previous year,” reports economist Karl Steininger. “This clearly means that Austria is not on track to meet its climate targets, which require a substantial reduction in emissions by 2030.”
