How does Oxygen get into a Fuel Cell?
How does Oxygen get into a Fuel Cell?
In order for a fuel cell to work, it needs an oxidising agent. TU Wien has now found a way to explain why oxygen does not always enter fuel cells effectively, rendering them unusable. Fuel cells use a simple chemical reaction, such as the combination of oxygen and hydrogen to form water, to generate electricity.

In a quantum race everyone is both a winner and a loser
In a quantum race everyone is both a winner and a loser
Our understanding of the world is mostly built on basic perceptions, such as that events follow each other in a well-defined order. Such definite orders are required in the macroscopic world, for which the laws of classical physics apply. However, in the quantum world orders can be ‘scrambled'.

Ravens: Non-breeders live in highly dynamic social groups
Ravens: Non-breeders live in highly dynamic social groups
Ravens have impressive cognitive skills when interacting with conspecifics - comparable to many primates, whose social intelligence has been related to their life in groups. An international collaboration of researchers led by Thomas Bugnyar, Professor at the Department of Cognitive Biology, University of Vienna, could uncover for the first time the group dynamics of non-breeding ravens.

How do metals interact with DNA?
How do metals interact with DNA?
Since a couple of decades, metal-containing drugs have been successfully used to fight against certain types of cancer. The lack of knowledge about the underlying molecular mechanisms slows down the search for new and more efficient chemotherapeutic agents. An international team of scientists, led by Leticia González from the University of Vienna and Jacinto Sá from the Uppsala University, have developed a protocol that is able to detect how metal-based drugs interact with DNA.

Why do people switch their language?
Why do people switch their language?
Due to increasing globalization, the linguistic landscape of our world is changing; many people give up use of one language in favour of another, a phenomenon called language shift. Katharina Prochazka and Gero Vogl from the University of Vienna have studied why language shift happens using the example of southern Carinthia, Austria.

Using molecules to detune nanodrums
Using molecules to detune nanodrums
The analysis of the minutest quantities of pharmaceutical samples is of crucial importance for the research and synthesis of new medications. At the moment it represents a technical challenge, but a new infrared method of measurement developed by TU Wien in collaboration with two research groups from Copenhagen may remedy this.

"Blurred Times" in a Quantum World
When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. However, combining quantum mechanics and Einstein's theory of general relativity theoretical physicists from the University of Vienna and the Austrian Academy of Sciences have demonstrated a fundamental limitation for our ability to measure time.

Who can find the fish that makes the best sound?
Who can find the fish that makes the best sound?
Using new computer algorithms, it is possible to adjust specific properties of three-dimensional objects, such as the sounds they produce or how stable they are. The thickness of a piece of metal made into different animal shapes - including a giraffe and a fish - is adjusted by using a computer algorithm in such a way that a specific sound spectrum is exhibited when the objects are struck.

Chiral Quantum Optics: A New Research Field with Bright Perspectives
Chiral Quantum Optics: A New Research Field with Bright Perspectives
Surprising direction-dependent effects emerge when light is guided in microscopic structures. This discovery shows promise for both classical and quantum information processing Recently, surprising physical effects were observed using special microscopic waveguides for light. Such "photonic structures" currently are revolutionizing the fields of optics and photonics, and have opened up the new research area of "Chiral Quantum Optics".

Neurotransmitter transporters are some of the most popular transport proteins in research as they play a major role in the processing of signals in the brain. A joint study by TU Wien and the Medical University of Vienna has now successfully demonstrated for the first time the structural impact of membrane lipids on medically relevant serotonin transporters.

"Weak Measurement" with strong results
Nuclear spin tomography is an application in (human) medicine known from medical institutions. The patient absorbs and re-emits electromagnetic radiation in all directions in space. They are detected and 3D images or 2D slice images are reconstructed from that data. Set in the framework of a fundamental science laboratory, the patient is replaced by a quantum object and the electromagnetic radiation by quantum measurement.
