Latest Vienna University of Technology Stories
Vienna University of Technology Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our daily lives. Ice cubes in a cocktail glass melt until an equilibrium state is reached in which the ice cubes are gone. After that, the geometric shape of the ice cubes is completely lost. The liquid does not contain any memory of their...
Vienna University of Technology Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna). Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only...
April Flowers for redOrbit.com - Your Universe Online Thermalization is the process of particles reaching thermal equilibrium through mutual interaction. We see this process around us every day. Take for example, ice cubes dropped into a pot of hot water. The cubes melt and cannot remain stable. Well-ordered ice crystals turn into a disordered liquid as the molecules of the ice and the molecules of the water reach thermal equilibrium, ending up at the same temperature. Research at the...
At the Vienna University of Technology, a very special kind of bright coherent x-ray radiation has been created by an international team of scientists; the new method was presented in the current issue of Science A breakthrough in laser science was achieved in Vienna: In the labs of the Photonics Institute at the Vienna University of Technology, a new method of producing bright laser pulses at x-ray energies was developed. The radiation covers a broad energy spectrum and can therefore be...
A strong laser beam can remove an electron from an atom – a process which takes place almost instantly. At the Vienna University of Technology, this phenomenon could now be studied with a time resolution of less than ten attoseconds (ten billionths of a billionth of a second). Scientists succeeded in watching an atom being ionized and a free electron being "born". These measurements yield valuable information about the electrons in the atom, which up until now hasn't been experimentally...
New laser-effect, discovered by scientists from the Vienna University of Technology, Princeton, Yale and ETH Zurich: If coupled, lasers can switch each other off, leading to a “laser blackout”. Two lamps are brighter than one. This simple truism does not necessarily apply to lasers, as a team of scientists, led by the Vienna University of Technology found out. When one laser is shining and next to it another laser is turned on gradually, complex interactions between the two lasers can...
Austrian researchers have claimed the world speed record for the fastest 3D-nanoprint of objects smaller than a grain of sand. The team was able to produce a scale model of a Formula-1 racecar one-hundredth-of-an-inch in length in just over four minutes. The car was produced in about 100 layers, each consisting of about 200 single printed lines. The researchers at the Vienna University of Technology (TU Vienna) said their technique is far faster than similar devices out there. They said...
Ultra-high-resolution 3D Printer Breaks Speed-Records at Vienna University of Technology Printing three dimensional objects with incredibly fine details is now possible using “two-photon lithography”. With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster...
Scientists at Vienna University of Technology have found a way to detect chemicals over long distances, even if they are enclosed in containers People like to keep a safe distance from explosive substances, but in order to analyze them, close contact is usually inevitable. At the Vienna University of Technology, a new method has now been developed to detect chemicals inside a container over a distance of more than a hundred meters. Laser light is scattered in a very specific way by...
Fungi with additional foreign genes have been created at the Vienna University of Technology - They can now turn chitin into pharmaceuticals Usually, mould fungi are nothing to cheer about – but now they can be used as "chemical factories". Scientists at the Vienna University of Technology have succeeded in introducing bacterial genes into the fungus Trichoderma, so that the fungus can now produce important chemicals for the pharmaceutical industry. The raw material used by the fungus is...
