Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis

The laser-based technology developed at TU Graz enables the continual real-time analysis of air pollutants and their interaction with other gases and sunlight

11-Apr-2024 - Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example is the formation of ground-level ozone when UV light hits nitrogen ...

New Method for Analysing Nanoporous Materials

Innovative method opens up new possibilities for materials science

22-Mar-2024 - Using only a single electron microscope image, researchers at TU Graz can determine the type and exact position of so-called guest atoms in high-tech materials. They also come closer to solving the mystery of the blue colour of aquamarine. In addition to their main components, the properties of ...

Looking at the Sides of Molecules: Lateral force microscopy reveals previously unseen hydrogen atoms

The ability to directly observe hydrogen atoms marks a significant breakthrough and opening up new avenues for research and innovation

23-Jan-2024 - Researchers at the University of Regensburg and the Graz University of Technology have shown that hydrogen atoms at the sides of molecules lying on a surface can directly be seen. The study, published in the journal “Proceedings of the National Academy of Sciences”, describes that by looking ...

Sniffing out carcinogens in foodstuffs

Andrea Hochegger, an analytical chemist at TU Graz, investigates whether foodstuffs can be tainted with harmful substances from packaging or during production

27-Sep-2022 - Andrea Hochegger’s current research focus is the question of contamination with mineral oil hydrocarbons. “We break up complex mixtures into MOSH and MOAH fractions,” Andrea explains. These are groups of chemical compounds found in mineral oil. MOSH stands for mineral oil saturated hydrocarbons ...
