The field of artificial intelligence is progressing. TU Vienna is a major center of this line of research. Several conferences on this topic will be held during the "Vienna Summer of Logic". The ball does not fit into the suitcase, because it is too small. What is too small? The ball or the suitcase? For humans the answer is evident, but computers still cannot handle such simple questions.

Experiments at the Vienna University of Technology can explain the behaviour of electrons at tiny step edges on titanium oxide surfaces. This is important for solar cell technology and novel, more effective catalysts. It can be found in toothpaste, solar cells, and it is useful for chemical catalysts: titanium dioxide (TiO2) is an extremely versatile material.

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.

Ultrathin layers made of Tungsten and Selenium have been created at the Vienna University of Technology. Experiments show that they may be used as flexible, semi-transparent solar cells. 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.

When soup is heated, it starts to boil. When time and space are heated, an expanding universe can emerge, without requiring anything like a "Big Bang". This phase transition between a boring empty space and an expanding universe containing mass has now been mathematically described by a research team at the Vienna University of Technology, together with colleagues from Harvard, the MIT and Edinburgh.

In magneto-electric materials, electric and magnetic vibrations can be coupled to "electromagnons". High hopes are placed on this technology, a breakthrough could now be achieved at the Vienna University of Technology (TU Wien).

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.

Scientists at the Vienna University of Technology manage to study the physics that connect the classical the quantum world. How does a classical temperature form in the quantum world? An experiment at the Vienna University of Technology has directly observed the emergence and the spreading of a temperature in a quantum system.

An international team of researchers at Vienna University of Technology in Austria and at Princeton University in the USA has confirmed theoretically-predicted interactions between single oxygen molecules and crystalline titanium dioxide. The results, which could be of importance for a variety of applications, have been published in the current.

Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled. The light they emit is as unique as a fingerprint: random lasers are tiny devices with a light emission pattern governed by random scattering of light.

Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology. All the objects around us emit thermal radiation.

Researchers from Vienna University of Technology have built a new interferometer for trapped, ultracold atomic gases. By strongly suppressing the quantum noise, which ultimately limits the performance of interferometers, they were able to curb the effect of atomic interactions, and increase the interrogation time of their interferometer.

Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period of time to realize global quantum networks based on optical fibers. Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables.

Catalysts can stop working when atoms on the surface start moving. At the Vienna University of Technology, this dance of the atoms could now be observed and explained. Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in.

A light wave oscillates perpendicular to its propagation direction - that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics experiments with light oscillating in the longitudinal direction. Storing light in a bottle is easier than one might think: Laser light can be coupled into an optical glass fiber in such a way that it does not travel along the fiber but rather spirals around it in a bulged, bottle-like section.

Fire blight is a serious threat to fruit trees. Now a quick test has been developed at the Vienna University of Technology, which can indicate the danger early - with the help of bees. When blossoms and leaves wilt and turn black, it is usually too late: the plant disease fire blight damages especially apple trees and pear trees, clearing the affected trees is often the only chance left.

A sponsorship by the Vienna Science and Technology Fund (WWTF) has enabled a new research group to be established at the Technical University of Vienna: Stefan Hetzl wants to link mathematical proof theory and language theory together. Infinitely many numbers, infinitely large quantities, infinitely many steps: In mathematics, one has to deal a lot with infinity.

An idea from EADS and Vienna University of Technology is taking off: in a joint project, Energy Harvester Modules suitable for aircrafts have been tested, which should supply sensor nodes with electrical power in the future. Like a nervous system in a human body, sensor networks attached to the aircraft fuselage will in future record and transmit essential data concerning the structural health of the aircraft.

Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell. Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted a great deal of attention among materials scientists in the last few years.

How can molecules be split in a controlled manner? A new experiment at the TU Vienna shows how research into ultra-short laser pulses can be combined with chemistry. Chemical reactions occur so quickly that it is completely impossible to observe their progress or to control them using conventional methods.
