Atomic force microscopy: new sensing element for high-speed imaging
Researchers at TU Wien have developed a new type of sensing element for atomic force microscopy, which enables a high measurement speed and can even image sensitive processes in living cells. High-definition images of minute objects are standard these days including the imaging of bacteria and viruses, and even molecules and individual atoms in extremely fine details.

Solving the Mystery of Quantum Light in Thin Layers
Solving the Mystery of Quantum Light in Thin Layers
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to glow in a highly unusual fashion.

Researchers show path of zearalenone through the womb using new technology The human foetus is considered to be particularly sensitive to environmental contaminants. A team led by Benedikt Warth from the Faculty of Chemistry at the University of Vienna and Tina Bürki from the Swiss Materials Science and Technology Institute, Empa, has now been able to demonstrate for the first time how the widespread food estrogen zearalenone behaves in the womb.

The fast dance of electron spins
The fast dance of electron spins
Chemists investigate the interactions of metal complexes and light Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role.

Fossil fish gives new insights into the evolution
"An experiment of nature" after the end-Cretaceous mass extinction An international research team led by Giuseppe Marramà from the Institute of Paleontology of the University of Vienna discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species.

Quantum Vacuum: Less than Zero Energy
Quantum Vacuum: Less than Zero Energy
Is it possible to borrow energy from an empty space? And if yes, do we have to give it back? Energy values smaller than zero are allowed - at least within certain limits. Energy is a quantity that must always be positive - at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached.

A metronome for quantum particles
A metronome for quantum particles
A new measurement protocol, developed at TU Wien (Vienna), makes it possible to measure the quantum phase of electrons - an important step for attosecond physics. It is like a microscope for time: Today's methods of attosecond physic allows us to measure extremely short time intervals. With the help of short laser pulses, physical processes can be investigated on a time scale of attoseconds - that is billionths of a billionth of a second.

2000 atoms in two places at once
The quantum superposition principle has been tested on a scale as never before in a new study by scientists at the University of Vienna in collaboration with the University of Basel. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to interfere.

From years to days: Artificial Intelligence speeds up photodynamics simulations
From years to days: Artificial Intelligence speeds up photodynamics simulations
Scientists use deep neural networks to achieve simulations on long time scales The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates the simulation of light-induced processes.

Searching for the Origin of Life across the Universe
Searching for the Origin of Life across the Universe
Researchers from European countries discuss life in the Universe at the University of Vienna Astrobiology is a young, rapidly developing branch of science that seeks to address the question of whether life exists, or has existed, elsewhere in the Universe. It is by nature an interdisciplinary science that explores the origins of life, the conditions, and processes that support or challenge life, the influence of different environmental conditions on preservation and detection of biosignatures of past and present life.

A new alphabet to write and read quantum messages with very fast particles
A new alphabet to write and read quantum messages with very fast particles
The interplay of quantum mechanics and special relativity requires a new alphabet to send reliable quantum messages Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails.

Entanglement sent over 50 km of optical fiber
Entanglement sent over 50 km of optical fiber
For the first time, a team led by Innsbruck physicist Ben Lanyon has sent a light particle entangled with matter over 50 km of optical fiber. This paves the way for the practical use of quantum networks and sets a milestone for a future quantum internet. The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology.

A molecular "Trojan Horse"
The research group of Nuno Maulide from the Faculty of Chemistry of the University of Vienna has, in cooperation with the Research Center for Molecular Medicine (CeMM) of the Austrian Academy of Sciences, achieved the synthesis of a potential immunosuppressive agent by modification of a naturally occurring compound.
