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.

Microbial interactions stabilize carbon in the soil
Microbial interactions stabilize carbon in the soil
Soils play a major role when it comes to the long-term storage of CO2 and the resulting reduction of this gas in the atmosphere - therefore they can contribute to slowing down climate change. In order to gain a better understanding of these mechanisms, it can be helpful to look at the microscopic level of soil microorganisms.

TU Graz develops autonomous electric compost turner
TU Graz develops autonomous electric compost turner
The new machine is intended to facilitate industrial composting and makes autonomous driving acceptable for chain-driven machines as well. Turning and mixing large compost heaps are important steps in composting to speed up the rotting process. Composting plants and agricultural businesses use mostly tractor-drawn turners or a diesel-powered compost turner with crawler track.

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.

Graphene: It is all about the toppings
To fully exploit the potential of the "wonder material" graphene, it has to be combined with other materials. A new study investigates what is important for this. Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical and optical properties have made graphene one of the most studied materials at the moment.
