Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How chaos theory mediates between them has now been studied at TU Wien. A single particle has no temperature. It has a certain energy or a certain speed - but it is not possible to translate that into a temperature.

Researchers at the University of Innsbruck investigated the effect of nuclear magnetic resonance on cryptochrome, an important protein of the "internal clock". To their surprise, the results of the experiments could only be explained by quantum mechanical principles - and could enable completely new therapeutic approaches.

When charged particles are being shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. This has now been explained at the TU Wien. It sounds a bit like a magic trick: Some materials can be shot through with fast, electrically charged ions without exhibiting holes afterwards.

The fine structure constant is one of the most important natural constants of all. At TU Wien, a remarkable way of measuring it has been found - it shows up as a rotation angle. One over 137 - this is one of the most important numbers in physics. It is the approximate value of the so-called fine structure constant - a physical quantity that is of outstanding importance in atomic and particle physics.

What determines the durability of high-performance coatings for turbines or highly stressed tools? Surprising results from TU Wien show: It is not material fatigue. Extremely thin ceramic coatings can completely change the properties of technical components. Coatings are used, for example, to increase the resistance of metals to heat or corrosion.

Tiny hairs on cell walls, so-called -cilia-, can move in unison to pump fluid. Now there finally is a physical theory describing these hairs' movements. They are only very simple structures, but without them we could not survive: Countless tiny hairs (cilia) are found on the outer wall of some cells, for example in our lungs or in our brain.

Tiny hairs on our cell walls can move together and thus pump fluid. Now they have succeeded in developing a physical theory of these hairs' movements . They are just very simple structures, but without them we could not survive: Countless tiny hairs are found on the outer wall of some cells, for example in our lungs or even in our brain.

TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices. Our current chip technology is largely based on silicon. Only in very special components a small amount of germanium is added. But there are good reasons to use higher germanium contents in the future: The compound semiconductor silicon-germanium has decisive advantages over today's silicon technology in terms of energy efficiency and achievable clock frequencies.

The computing power of quantum computers is currently still very low. Increasing it is currently still proving to be a major challenge. Physicists at the University of Innsbruck now present a new architecture for a universal quantum computer that overcomes such limitations and could be the basis for building the next generation of quantum computers in the near future.

By Birgit Baustädter Scientists at TU Graz in cooperation with the University of Surrey were able to observe and document the growth of hexagonal boron nitride for the first time. The material is mainly used in microelectronics and nanotechnology. Atomically thin 2D materials for applications in microelectronics or nanotechnology are grown by breaking down gas on a hot metal surface.

For fusion reactors like ITER, plasma instabilities are a major challenge. A research team around the nuclear fusion group at TU Wien has now found a promising solution. Nuclear fusion power plants could one day provide a sustainable solution to our energy problems - but to date there is no commercial nuclear fusion reactor in operation.

Because they are extremely stable, so-called "topological states" play an important role in materials research. Now, for the first time, it has been possible to switch such states on and off. A donut is not a breakfast roll. Those are two very clearly distinguishable objects: One has a hole, the other does not.

Researchers at TU Vienna and FHI Berlin succeeded in monitoring a catalytic reaction with three different microscopies under exactly the same conditions in real time. In this way, information is obtained that none of the methods alone could reveal. One has to look very closely to exactly understand what processes take place on the surfaces of catalysts.

Designing New Quantum Materials on the Computer
A new design principle can now predict the properties of quantum materials that have hardly been explored so far. For the first time, a strongly correlated topological semimetal has been discovered using a computer. How do you find novel materials with very specific properties - for example, special electronic properties which are needed for quantum computers?

A fingertip-sized chip replaces bulky laboratory equipment. An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds.

When ions penetrate a material, highly complex processes take place - so fast that they could hardly be analyzed until now. But sophisticated measurements have now made it possible. How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research - for example in nuclear fusion research, when the walls of the fusion reactor are bombarded by high-energy ions, but also in semiconductor technology, when semiconductors are bombarded with ion beams to produce tiny structures.

Defective Material Forms Spin Structures: JKU Physicists Explain & Surprising Experiment
What is more important in research: theory or experiments? Ideally, both, as a collaboration between Johannes Kepler University Linz and the Max Planck Institute in Halle shows. The Linz physicists were able to provide the theoretical explanation for surprising results in experiments in Germany. The German researchers had determined certain CrTe2 structures with X-ray spectroscopy - and came across skyrmions.

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate.

Hyperpolarised water boosts signal intensities of proteins, DNA, and membranes A small group of researchers including Dennis Kurzbach from the Faculty of Chemistry of the University of Vienna just published in "Nature Protocols" an advanced NMR (Nuclear Magnetic Resonance) method to monitor fast and complicated biomolecular events such as protein folding.

By Susanne Filzwieser The "smart skin" developed by Anna Maria Coclite is very similar to human skin. It senses pressure, humidity and temperature simultaneously and produces electronic signals. More sensitive robots or more intelligent prostheses are thus conceivable. Photographic material for Download at the end of the text The skin is the largest sensory organ and at the same time the protective coat of the human being.
