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.

Laboratory experiments could unravel the mystery of the Mars moon Phobos
What causes the weathering of the Mars moon Phobos? Results from TU Wien give new insights, soon a spacecraft will retrieve soil samples. Of course, there is no weather in our sense of the word in space - nevertheless, soil can also "weather" in the vacuum of space if it is constantly bombarded by high-energy particles, such as those emitted by the sun.

Laser technology: New Trick for Infrared Laser Pulses
Laser technology: New Trick for Infrared Laser Pulses
Infrared light can be used to detect molecules - but it is hard to create strong, short laser pulses. A new solution was found at TU Wien. Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed.

Attention, the electron is too fast!
Attention, the electron is too fast!
Why do different measurements of material properties sometimes give different results? A research team led by the TU Vienna has now found an important answer. It is very hard to take a photo of a hummingbird flapping its wings 50 times per second. The exposure time has to be much shorter than the characteristic time scale of the wing beat, otherwise you will only see a colorful blur.

Autophagy: the beginning of the end
Autophagy: the beginning of the end
Scientists reveal key steps in the formation of the recycling cen-ters of the cell Autophagy, from the Greek for 'self-eating', is an essential process that isolates and recycles cellular components under conditions of stress or when resources are limited. Cargoes such as misfolded proteins or damaged organelles are captured in a double membrane-bound com-partment called the autophagosome and targeted for degradation.

The Art of Making Tiny Holes
The Art of Making Tiny Holes
How can you perforate an atomic layer of material and leave the one underneath intact? Scientists at TU Wien (Vienna) developed a technique for processing surfaces on an atomic scale. Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact.

New Materials for Extra Thin Computer Chips
New Materials for Extra Thin Computer Chips
For a long time, something important has been neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials. Ever smaller and ever more compact - this is the direction in which computer chips are developing, driven by industry. This is why so-called 2D materials are considered to be the great hope: they are as thin as a material can possibly be, in extreme cases they consist of only one single layer of atoms.

New quasi-particle discovered: the Pi-ton
Actually they had been looking for something completely different, but they found a previously unknown quasi-particle: A bound state of two electrons, two holes and light. In physics, there are very different types of particles: Elementary particles are the fundamental building blocks of matter. Other particles, such as atoms, are bound states consisting of several smaller constituents.
