When changing one atom makes molecules better
Chemists in Vienna find a method to replace hydrogen with fluorine in organic molecules The development and improvement of pharmaceuticals plays the central role in the ongoing battle against human disease. Organic synthesis is the field that enables these developments as it offers the toolbox to diversify chemical structures.

Coebro: 3D-Printers Learn to Build Houses
Coebro: 3D-Printers Learn to Build Houses
Many things today can be produced simply, fast and cheaply using a 3D printer: jewelry, small components and even prototypes. Printing complete houses is still a long way off. For the moment, at least. But work is being done at TU Graz on additive manufacturing of concrete parts using printing robots.

How to Freeze Heat Conduction
How to Freeze Heat Conduction
Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy. Every day we lose valuable energy in the form of waste heat - in technical devices at home, but also in large energy systems.

Superconduction: Why does it have to be so cold?
Superconduction: Why does it have to be so cold?
Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance.

The Internet of Things: TU Graz researchers increase the dependability of smart systems
The Internet of Things: TU Graz researchers increase the dependability of smart systems
By Christoph Pelzl Since 2016 a team from TU Graz has been working on dependability in the Internet of things. After having achieved remarkable success, the eponymous research project is now going into the second phase. Smart systems are taking over the increasingly complex tasks of our private and professional daily lives.

Cryptographer with a penchant for crayons
Cryptographer with a penchant for crayons
Cryptographer Maria Eichlseder hides our messages from curious eyes that shouldn't read them. With her love of paper she defies the classical image of a computer scientist. The sun shines through the long roof window on the second floor of Inffeldgasse 16. It touches the concrete wall, makes the silver railings shine, and replenishes the large-leafed potted plants with energy.

To tool or not to tool?
To tool or not to tool?
Orangutans make complex economic decisions about tool use depending on the current 'market' situation Flexible tool use is closely associated to higher mental processes such as the ability to plan actions. Now a group of cognitive biologists and comparative psychologists from the University of Vienna, the University of St Andrews and the University of Veterinary Medicine Vienna that included Isabelle Laumer and Josep Call, has studied tool related decision-making in a non-human primate species - the orangutan.

New Wheelchair Design: a Hand Gear for better Ergonomics
New Wheelchair Design: a Hand Gear for better Ergonomics
Using biomedical modelling, researchers at TU Wien have developed a completely new type of wheelchair. Specially designed handles make the drive more efficient and ergonomic. Anyone who thinks that a wheelchair is a simple piece of equipment with no room for improvement is sorely mistaken. The research team for biomechanics and rehabilitation engineering at TU Wien (Vienna) has now developed a completely new drive system.

Deep sea reveals linkage between earthquake and carbon cycle
Deep sea reveals linkage between earthquake and carbon cycle
In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the amount of organic carbon transported into the deep sea by a single tectonic event, the giant Tohoku-oki earthquake in 2011.

Where does this contamination come from?
Where does this contamination come from?
When bodies of water become polluted, it is important to find the cause as quickly and as economically as possible. To this end, TU Wien has now developed a new, DNA-based rapid testing procedure. Water contamination is one of the world's major health risks. In order to swiftly resolve the problem in the event of faecal contamination, it is vital that the cause is identified as quickly as possible: is it contamination from agriculture?

Faster than allowed by quantum computing?
Faster than allowed by quantum computing?
Researchers determine the performance of multi-dimensional bits Quantum computers are more powerful than classical computers since they work with coherent "quantum bits" instead of ordinary zeroes and ones. But what if the laws of nature were different from what we think today - could there be even more efficient "science fiction computers"- Researchers from the Austrian Academy of Sciences and the University of Vienna have now shown that this is not possible - as long as those machines satisfy the same construction principles as ordinary circuits and their quantum counterparts.

How does a quantum particle see the world?
Researchers at the University of Vienna study the relevance of quantum reference frames for the symmetries of the world According to one of the most fundamental principles in physics, an observer on a moving train uses the same laws to describe a ball on the platform as an observer standing on the platform - physical laws are independent on the choice of a reference frame.

Superconductors: Resistance is Futile
Superconductors: Resistance is Futile
New findings are changing the way we think about superconductivity. Experiments at TU Wien (Vienna) underline the special role of immobile charge carriers, acting as a 'glue', which makes superconductivity possible. Every standard cable, every wire, every electronic device has some electric resistance.

The impacts of invasive species are often difficult to predict
Researchers develop approach to protect biodiversity New Zealand and other islands have experienced invasions of rats, Europe has seen the arrival of the spinycheek crayfish, spreading a deadly disease called crayfish plague: invasive species can put native animal and plant species on the brink of extinction.

Herbal antioxidants are becoming increasingly important
Herbal antioxidants are becoming increasingly important
Secondary plant compounds as an alternative to antioxidant vitamins and minerals The human organism is constantly exposed to so-called free radicals, which are a burden on the body. If they get out of hand, the result is oxidative stress, which can promote disease. While this has been treated in the past with the help of antioxidant vitamins and minerals, scientists are now increasingly turning to the use of phytochemicals, representing plant secondary metabolites.

Viennese Scientists develop promising new type of polymers
Viennese Scientists develop promising new type of polymers
S-PPV polymers are suitable for use in a wide range of applications, from solar cells through to medicine but, until recently, they were almost impossible to produce. Now, a new synthetic method has been patented. Organic polymers can nowadays be found in solar cells, sensors, LEDs and in many other technical applications.
