New research method answers important questions
15-Jan-2021
Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface. This phenomenon has been known for a long time, but until now it has ...
Novel microcopy methods allow scientists to study the mechanical interaction of T-cells and particles
04-Jan-2021
When T-cells of our immune system become active, tiny traction forces at the molecular level play an important role. They have now been studied at TU Wien. Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy ...
In order to analyze tumors, they have to be cut into thin slices. Now, a new technology has been developed that makes pieces of the tumor visible in 3D without cutting them
29-Oct-2020
After cancer surgery, the crucial question is: Are there possibly cancer cells left behind that can continue to grow, or has the entire tumor actually been removed? To find out, the tumor is examined by pathologists. Until now, thin sections were made which were then analyzed under a microscope. ...
Why do different measurements of material properties sometimes give different results?

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. A very similar problem is encountered in solid-state physics, where ...
Scientists photographed, for the first time, individual atoms floating less than a thousandth of a millimeter above a light-conducting glass fiber
06-Aug-2020
The first photograph of a single trapped atom represented a milestone for quantum research. This breakthrough was made possible because the atom was captured in a vacuum using electric fields and held far from surfaces whose scattered light could blind the camera. Scientists at Humboldt ...
How can surfaces be studied as gently as possible on an atomic scale?
10-Jun-2020
Oxygen is highly reactive. It accumulates on many surfaces and determines their chemical behavior. At the Vienna University of Technology, scientists study the interaction between oxygen and metal oxide surfaces, which play an important role in many technical applications - from chemical sensors ...

Advances in neuroscience research and microscopy: Researchers look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders. Analyses of individual cells in the context of whole organs or tissues is becoming increasingly important in biology. A ...
Ultra-fast image sensor with a built-in neural network can be trained to recognize certain objects
06-Mar-2020
Automatic image recognition is widely used today: There are computer programs that can reliably diagnose skin cancer, navigate self-driving cars, or control robots. Up to now, all this has been based on the evaluation of image data as delivered by normal cameras - and that is time-consuming. ...

"Frequency combs" are optimally suited for chemical sensors. A revolutionary technology developed at TU Wien (Vienna) now produces these laser frequencies in a much easier and more robust way. Most lasers have only one color. All the photons it emits have exactly the same wavelength. However, ...
14-Nov-2018
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way. Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, ...
