How a chemical reaction takes place that, at first glance, should not be possible at the temperatures observed
05-Apr-2022
What happens when a cat climbs onto a sunflower? The sunflower is unstable, will quickly bend, and the cat will fall to the ground. However, if the cat only needs a quick boost to catch a bird from there, then the sunflower can act as a "metastable intermediate step". This is essentially the ...
A novel, simple and extremely compact radiation source for terahertz waves: The possible applications are manifold.
13-Jan-2022
Terahertz radiation has a wavelength of typically a little less than one millimetre - a technically difficult range. Electromagnetic waves with longer wavelengths can be generated with ordinary electronic components (such as transistors) and antennas. Smaller wavelengths can be obtained with ...
Researchers are investigating new materials that can be used to reduce the operation temperature of solid oxide fuel cells: To do so, they apply an innovative method
02-Dec-2021
Solid oxide fuel cells consist of three important parts: an anode, a cathode and an electrolyte. While oxygen is incorporated into the cathode, oxygen is then transported through the electrolyte to the anode, where oxygen reacts with hydrogen to water. The fuel cell is able to convert the energy ...
This is important to determine the quality of a sample and to clearly attribute effects to the transport vesicles
26-Oct-2021
To transport substances between cells, they are packaged in nanovesicles. The small vesicles are surrounded by a lipid layer and fuse with the cell membrane at their destination. Within the body, they control many important processes. However, it is still unclear whether the influence in ...
Mix of methods provides new info
07-Jul-2021
Although the history of bitumen dates back to the third millennium BC, only little is known about its surface structure. Researchers from TU Wien are now shedding light on the nature of the bitumen surface using physicochemical analyses. While atomic force microscopy and scanning electron ...
Precisely understand and improve chemical properties of surfaces
30-Apr-2021
The acidity of molecules can be easily determined, but until now it was not possible to measure this important property for atoms on a surface. With a new microscopy technique from the Vienna University of Technology (TU Wien), this has now been achieved. The degree of acidity or alkalinity of a ...
Researchers create special light waves that can penetrate even opaque materials as if the material was not even there
14-Apr-2021
Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light ...
How do you measure objects that you can't see under normal circumstances?
27-Jan-2021
Laser beams can be used to precisely measure an object’s position or velocity. Normally, however, a clear, unobstructed view of this object is required – and this prerequisite is not always satisfied. In biomedicine, for example, structures are examined, which are embedded in an irregular, ...
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 ...
