TU Wien The calorie free sweetener erythritol is widely used in Asia; it is also gaining popularity in Europe and America. At the Vienna University of Technology, a new cheap method has been developed to produce erythritol from straw with the help of mould fungi. Erythritol has many great advantages: it does not make you fat, it does not cause tooth decay, it has no effect on the blood sugar and, unlike other sweeteners, it does not have a laxative effect. In Asia it is already widely...

High-Strength Materials Created From The Pressure Cooker
2014-05-05 12:15:30

Florian Aigner, Vienna University of Technology A Surprise in Materials Chemistry: At Vienna University of Technology, materials for lightweight construction, protective clothing or sports equipment can be produced at high temperatures and high pressures. This process is faster, better and more eco-friendly than other techniques. The earth’s crust works like a pressure cooker. Minerals typically do not form under standard conditions, but at high temperatures and pressures. However,...

Faster Dental Treatment With New Dental Filling Material
2014-05-01 03:46:56

Vienna University of Technology A new dental filling material, developed at the Vienna University of Technology, is easier to harden. It makes dental treatment faster and easier. In modern dentistry, amalgam fillings have become unpopular. Instead, white composite materials are more commonly used, which at first glance can hardly be distinguished from the tooth. The majority of these composites are based on photoactive materials that harden when they are exposed to light. But as the...

Scientists Use Neutrons To Search For Dark Energy
2014-04-17 10:13:42

Vienna University of Technology With neutrons, scientists can now look for dark energy in the lab All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and "Dark Energy" – remains mysterious. A European collaboration led by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin...

Schematic of the detector: the metamaterial couples the incident light to the semiconductor, and then it can be converted into an electric signal
2014-03-30 06:26:20

Florian Aigner, Vienna University of Technology A new, extremely thin kind of light detector was created at Vienna University of Technology. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures. Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light...

Atomically Thin Solar Cells
2014-03-10 10:44:34

Vienna University of Technology It does not get any thinner than this: The novel material graphene consists of only one atomic layer of carbon atoms and exhibits very special electronic properties. As it turns out, there are other materials too, which can open up intriguing new technological possibilities if they are arranged in just one or very few atomic layers. Researchers at the Vienna University of Technology have now succeeded for the first time in creating a diode made of tungsten...

Single-Atom Light Switch
2013-11-06 10:32:04

Vienna University of Technology With just a single atom, light can be switched between two fiber optic cables at the Vienna University of Technology. Such a switch enables quantum phenomena to be used for information and communication technology. Fiber optic cables are turned in to a quantum lab: scientists are trying to build optical switches at the smallest possible scale in order to manipulate light. At the Vienna University of Technology, this can now be done using a single atom....

World’s Most Powerful Terahertz Quantum Cascade Laser Developed
2013-10-30 10:39:08

Vienna University of Technology Whether it is diagnostic imaging, analysis of unknown substances or ultrafast communication – terahertz radiation sources are becoming more and more important. At the Vienna University of Technology, an important breakthrough has been achieved. Terahertz waves are invisible, but incredibly useful; they can penetrate many materials which are opaque to visible light and they are perfect for detecting a variety of molecules. Terahertz radiation can be...

Caged Atoms Used To Create Electricity
2013-09-23 08:49:43

Vienna University of Technology At the Vienna University of Technology, a new class of thermoelectric materials has been discovered; Due to a surprising physical effect they can be used to create electricity more efficiently A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects. At the Vienna...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
