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, ...

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, ...
A microscopy technique in which sound is measured instead of light.
28-Sep-2018
Individual molecules cannot be photographed – if you wish to visualise objects that are smaller than the wavelength of light, you'll need a few special tricks up your sleeve. You can use electron microscopes for example, or determine the position of specific fluorescent molecules by taking a ...

Atomically thin crystals will play an ever greater role in future – but how can their crystallisation process be controlled? A new method is now opening up new possibilities. They are among the thinnest structures on earth: “two dimensional materials” are crystals which consist of only one or a ...
Patented vibration damping system enables images of highest quality
10-Apr-2018
To produce images of individual atoms, a microscope shouldn't shake. A patented vibration damping system developed at the TU Wien enables images of the highest quality. It is one of the most accurate measurement instruments available today: the high-performance microscope at the Institute of ...
