The Mechanics of the Immune System
The Mechanics of the Immune System
When T-cells of our immune system become active, tiny traction forces at the molecular level play an important role. They have now been studied at TU Wien. Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock.

Mmm, what a 'taste'
Mmm, what a ’taste’
By Mag. Beate Mosing The researchers at the sensory laboratory of the Institute of Analytical Chemistry and Food Chemistry at TU Graz know that "taste" alone is by no means the only decisive factor for culinary enjoyment. "From a scientific point of view, we only distinguish between sweet, sour, salty, bitter and umami in terms of taste.

Hydrogen: Electricity Storage of the Future?
By Birgit Baustädter If our energy system is to become more eco-friendly, there is no way to avoid hydrogen as an energy carrier. Researchers around the world are certain of this. Hydrogen is the first element in the periodic table. Not only here does it occupy a prominent place, but also in the discussion about an eco-friendly energy system of the future.

Time for plan A
Time for plan A
By Dr. Daniela Müller Oil, gas and coal were yesterday. Hydrogen could be the key to a green future. Its versatility has made hydrogen a research core area at Graz University of Technology for 50 years. What was that again about hydrogen, symbol H, a chemical element in the periodic table? That made the Hindenburg explode, removes hair dye and powers a few vehicles? Usually very little of what we learnt at school is remembered about it, apart from the oxyhydrogen gas reaction.

Stable Catalysts for New Energy
Stable Catalysts for New Energy
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.

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.

Cyanobacteria as 'green' catalysts in biotechnology
Cyanobacteria as ’green’ catalysts in biotechnology
By Susanne Eigner Researchers from TU Graz and Ruhr University Bochum show in the journal ACS Catalysis how the catalytic activity of cyanobacteria, also known as blue-green algae, can be significantly increased. This brings biotechnological and thus eco-friendly application a big step closer. Cyanobacteria, despite staining water green through their special pigments, are colloquially known as "blue-green algae", and convert light energy into chemical energy particularly effectively thanks to their highly active photosynthetic cells.
