Crucial new technologies such as hydrogen production or carbon capture require new catalysts. Experiments show: It's not just the material that matters, but also its atomic surface structure. On the way to a CO2-neutral economy, we need to perfect a whole range of technologies - including the electrochemical extraction of hydrogen from water, fuel cells, or carbon capture.

Laser technology: New Trick for Infrared Laser Pulses
Laser technology: New Trick for Infrared Laser Pulses
Infrared light can be used to detect molecules - but it is hard to create strong, short laser pulses. A new solution was found at TU Wien. Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed.

Sustainable shotcrete mix-designs for tunnels with longer service-life
A project jointly initiated by the Austrian Society for Construction Technology (ÖBV), TU Graz and OTH Regensburg provides a more systematic understanding of shotcrete applications and forms the basis for new, even more durable concrete mixes and thus for more durable tunnels. The service life of tunnels today is designed to last at least for one hundred years - in the case of the Brenner basis tunnel it is even 200 years.

Sticky Electrons: When Repulsion turns into Attraction
For years, physicists at TU Wien have been studying strange phenomena - now they have found an explanation that could help to understand unconventional types of superconductivity. Materials can assume completely different properties - depending on temperature, pressure, electrical voltage or other physical quantities.

Sweet taste reduces appetite?
Sweet taste reduces appetite?
The sweet taste of sugar, energy intake and the regulatory process of hunger and satiety To date, very little is known about how sweetness perception contributes to satiety. This study, conducted by an Austrian-German team led by chemists Veronika Somoza and Barbara Lieder, provides new insights into the relationship between the sweet taste of sugar, energy intake and the regulatory process of hunger and satiety.

Graz researchers identify biomarker for cardiovascular diseases
Graz researchers identify biomarker for cardiovascular diseases
The role of the enzyme dipeptidyl peptidase 3 in the blood pressure-regulating renin-angiotensin system was investigated in the inter-university cooperation project BioTechMed-Graz. The results could pave the way for new therapies for cardio-renal diseases. The renin-angiotensin system (RAS) becomes active at low blood pressure and forms angiotensin II, a hormone that causes blood vessels to constrict, causing blood pressure to rise again.

New cancer diagnostics: A glimpse into the tumor in 3D
New cancer diagnostics: A glimpse into the tumor in 3D
In order to analyze tumors, they have to be cut into thin slices. Now, a new technology has been developed that makes pieces of the tumor visible in 3D without cutting them. After cancer surgery, the crucial question is: Are there possibly cancer cells left behind that can continue to grow, or has the entire tumor actually been removed? To find out, the tumor is examined by pathologists.

Taking a look at generosity within the crow family reveals parallels with human evolution. Working together to raise offspring and increased tolerance towards group members contribute to the emergence of generous behavior among ravens, crows, magpies and company - similarly as it did for our human ancestors.

New sediment archive for historical climate research
Geological investigations of low-temperature young deposits on the Styrian Erzberg provide paleoclimatology with new data on the earth's history and its development. Additional pictures for download at the end of the text How has the climate changed in the course of the earth's history? Which climatic processes have influenced the earth and its atmosphere? Paleoclimatology seeks answers to such questions in order to better understand climate changes and to derive forecasts for future climate scenarios.
