Magnonic nano-fibers opens the way towards new type of computers
Magnonic nano-fibers opens the way towards new type of computers
Magnetism offers new ways to create more powerful and energy-efficient computers, but the realization of magnetic computing on the nanoscale is a challenging task. A critical advancement in the field of ultralow power computation using magnetic waves is reported by a joint team from Kaiserslautern, Jena and Vienna in the journal Nano Letters.

Less gold is Sometimes Better
Less gold is Sometimes Better
Using an ultra-thin gold layer, scientists at TU Wien (Vienna) succeeded in creating an almost optimal infrared absorber. Possible applications range from astrophysics to virus detection. Infrared detectors play an important role in research: many molecules absorb electromagnetic radiation in the infrared range in a very characteristic way.

Cool down fast to advance quantum nanotechnology
Cool down fast to advance quantum nanotechnology
Rapidly cooling magnon particles proves a surprisingly effective way to create an elusive quantum state of matter, called a Bose-Einstein condensate. The discovery can help advance quantum physics research and is a step towards the long-term goal of quantum computing at room temperature. An international team of scientists have found an easy way to trigger an unusual state of matter called a Bose-Einstein condensate.

New quasi-particle discovered: the Pi-ton
New quasi-particle discovered: the Pi-ton
Actually they had been looking for something completely different, but they found a previously unknown quasi-particle: A bound state of two electrons, two holes and light. In physics, there are very different types of particles: Elementary particles are the fundamental building blocks of matter. Other particles, such as atoms, are bound states consisting of several smaller constituents.

The paint testing machine
The paint testing machine
How can you prevent cracks from forming after painting? TU Wien has recently patented two new measuring processes that show which paint is best. It's a familiar problem for anyone who has renovated a house or flat: no building is a perfectly rigid body. Walls and ceilings can move slightly over time, which often leads to cracks in the paint on the walls.

Record-breaking Terahertz Laser Beam
Record-breaking Terahertz Laser Beam
A new, extremely efficient source of terahertz radiation has been developed at TU Wien (Vienna): Lasers turn air into plasma, thereby producing terahertz rays for many possible applications. Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry.

A New Look at
A New Look at "Strange Metals"
For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. The results have been published in "Science". Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature.

New Material Breaks World Record Turning Heat into Electricity
New Material Breaks World Record Turning Heat into Electricity
A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly. Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: If there is a temperature difference between the two ends of such a material, electrical voltage can be generated and current can start to flow.

Bioprinting: Living cells in a 3D printer
Bioprinting: Living cells in a 3D printer
With a new process developed at TU Wien (Vienna), living cells can be integrated into fine structures created in a 3D printer - extremely fast and with very high resolution. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework.

Solving the Mystery of Quantum Light in Thin Layers
Solving the Mystery of Quantum Light in Thin Layers
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to glow in a highly unusual fashion.

From Japanese basket weaving art to nanotechnology with ion beams
Ultradense arrays of magnetic quanta in high-temperature superconductors The properties of high-temperature superconductors can be tailored by the introduction of artificial defects. An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world's densest complex nano arrays for anchoring flux quanta, the fluxons.

New findings could lead to cheaper solar cells
Effective atomic interactions in complex materials picked up by on-the-fly machine-learning At the atomic scale materials can show a rich palette of dynamic behaviour, which directly affects the physical properties of these materials. For many years, it has been a dream to describe these dynamics in complex materials at various temperatures using computer simulations.

For a longer battery life: Pushing lithium ion batteries to the next performance level
Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international scientists have developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries.
