Single atoms as a catalyst: Surprising effects ensue
For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team at TU Wien in Vienna, Austria have shown that everything is suddenly different when you arrive at the smallest possible size: a single atom. Metals such as gold or platinum are often used as catalysts.

In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago.

Catalysts: Worth Taking a Closer Look
Catalysts: Worth Taking a Closer Look
Why do metal oxide surfaces behave differently? At TU Wien, a new research method was found to answer important questions. Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface.

More than just a sun tan: ultraviolet light helps marine animals to tell the time of year
More than just a sun tan: ultraviolet light helps marine animals to tell the time of year
Changes in daylength are a well-established annual timing cue for animal behavior and physiology. An international collaboration of scientists led by Kristin Tessmar-Raible at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, now shows that, in addition to daylength, marine bristle worms sense seasonal intensity changes of UVA/deep violet light to adjust the levels of important neurohormones and their behavior.

Toboggan accident crash test: Without helmet, serious injuries even at low speeds
Austrian Road Safety Board, and TU Graz have investigated tobogganing accidents for the first time in a computer-simulated crash test. The results: Wearing a helmet and the correct sitting position dramatically reduce the risk of injury for children while tobogganing. More than 2,200 people are injured in toboggan accidents in Austria every year.

Unusual sex chromosomes of platypus, emu and duck
Unusual sex chromosomes of platypus, emu and duck
Three papers unveil the extraordinary diversity of animal sex chromosomes The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually appear as one pair of morphologically different chromosomes between sexes. For example, women have one pair of XX chromosomes, while men have one pair of XY chromosomes.

Ancient DNA shines light on Caribbean prehistory
An international team of scientists reveals the genetic makeup of the people who lived in the Caribbean between about 400 and 3,100 years ago-at once settling several archaeologic and anthropologic debates, illuminating present-day ancestries and reaching startling conclusions about Indigenous population sizes when Caribbean cultures were devastated by European colonialism beginning in the 1490s.

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.

When less is more: a single layer of atoms boosts the nonlinear generation of light
When less is more: a single layer of atoms boosts the nonlinear generation of light
A wide array of technologies, ranging from lasers and optical telecommunication to quantum computing rely on nonlinear optical interaction. Typically, these nonlinear interactions, which allow a beam of light, for example, to change its frequency, are implemented by bulk materials. In a new study an international research team led by the University of Vienna have shown that structures built around a single layer of graphene allow for strong optical nonlinearities that can convert light.

Learning about Quantum Vacuum by Studying Atoms
Learning about Quantum Vacuum by Studying Atoms
The Unruh-effect connects quantum theory and relativity. Until now, it could not be measured. A new idea could change this - in a completely different way than ever before. Is the vaccum really empty? Not necessarily. This is one of the strange results obtained by connecting quantum theory and the theory of relativity: The Unruh effect suggests that if you fly through a quantum vacuum with extreme acceleration, the vacuum no longer looks like a vacuum: rather, it looks like a warm bath full of particles.

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.
