Customised Thermal Radiation
Customised Thermal Radiation
Normally, thermal radiation is a product of randomness, described by the laws of statistical physics. TU Wien and the University of Manchester show that it can also be controlled. When a piece of metal is made to glow, its colour depends solely on its temperature. The material, the geometry, the structure of its surface - none of these details matters.

What waves know about their environment
What waves know about their environment
Waves carry information about their surroundings. An exact theory has now been developed at TU Wien - with astonishing results that can be used for technical purposes. No matter whether ultrasound is used to study the body, radar systems to study airspace or seismic waves to study the interior of our planet: You are always dealing with waves that are deflected, scattered or reflected by their surroundings.

Switching Nanomagnets Using Infrared Lasers
Switching Nanomagnets Using Infrared Lasers
Physicists at TU Graz have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits. When molecules are irradiated with infrared light, they begin to vibrate due to the energy supply.

TU Graz Revolutionises Simulation of Metal-Organic Frameworks (MOFs)
Due to the complex structures of microporous crystals known as MOFs, reliable simulations of their properties have been difficult until now. Machine learning provides the solution. Hydrogen storage, heat conduction, gas storage, CO2 and water sequestration - metal-organic frameworks (MOFs) have extraordinary properties due to their unique structure in the form of microporous crystals, which have a very large surface area despite their small size.

Beneath the Surface
Beneath the Surface
To grow their roots, plants feel gravity - ISTA scientists take a close look Using the force of gravity, roots weave their way through the soil to provide a plant with both structural support and essential nutrients. Anastasia Teplova from the Friml group at the Institute of Science and Technology Austria (ISTA) investigates the mechanism behind this process.

New method unravels the mystery of slow electrons
New method unravels the mystery of slow electrons
Slow electrons are used in cancer therapy as well as in microelectronics. It is very hard to observe how they behave in solids. But scientists at TU Wien have made this possible. Electrons can behave very differently depending on how much energy they have. Whether you shoot an electron with high or low energy into a solid body determines which effects can be triggered.

High-tech Gemstones for Nuclear Science
High-tech Gemstones for Nuclear Science
Special thorium-containing crystals, developed over many years at TU Wien, were crucial in tracking down the long-sought thorium transition. Emerald, ruby, amethyst and many other gemstones have one thing in common: they consist of a perfectly regular crystal structure into which foreign atoms are incorporated in low concentrations.
