Researchers have discovered how sloshing movements can be actively suppressed during the highly dynamic transportation of liquids . In highly automated industrial processes, machines, materials and goods are often moved very quickly. It is important that these movements are carried out precisely and safely.

By Birgit Baustädter In the Turbomachinery Laboratory at the Institute of Thermal Turbomachinery and Machine Dynamics at TU Graz, Emil Göttlich, head of the laboratory, and his research team study the aerodynamics of aircraft engines. In the transonic test turbine facility, the inflow conditions in an aircraft engine can be realistically simulated from take-off to landing at around 60° to 80° Celsius.

By Christoph Pelzl In the EU project TURANDOT, researchers from TU Graz investigated a sharkskin-like coating for engine blades and tracked the flow of cooling air in the engine. In this way, they make aircraft more fuel-efficient, less expensive and quieter. Additional Images for download at the end of the text An engine is more efficient and quieter the larger and slower the fan (note: that's the turbofan at the front of the jet engine) is.

Decades-old data is being used to describe the propagation of tiny droplets. Now a fluid dynamics team has developed new models: Masks and distancing are good, but not enough. 1/2 images Droplets with a viral load [Translate to English:] Tröpfchen haben begrenzte Reichweite, Aeorsole können aber größere Distanzen überbrücken [Translate to English:] Tröpfchen haben begrenzte Reichweite, Aeorsole können aber größere Distanzen überbrücken Wear a mask, keep your distance, avoid crowds - these are the common recommendations to contain the COVID-19 epidemic.

By Werner Schandor In the CHIP project, Ceratizit Austria, TU Darmstadt, Material Center Leoben and TU Graz are improving the recording and analysis of heat flows in milling machining. With sensational results. "What is sensational about our project can be found hidden away in this rather inconspicuous chart," says Franz Haas from the Institute of Production Engineering as he points to a diagram reproducing a saw-toothed temperature progression for the period of a tenth of a second (Figure 2).

By Eberhard Schutting New types of vehicles have to prove their conformity to emission standards in thetype approval test. Previous procedures were criticized for insufficiently reflecting the real driving pattern. Thus, end of 2017, the regulatory authorities (the EC) introduced a new test procedure that includes the measurement of emissions during real¬world driving, commonly known as RDE legislation (Real Driving Emissions).

A special formula for epoxy resins has been developed at TU Wien, which can be used for fibre-reinforced composites in aerospace, shipbuilding and automotive manufacturing, or even for underwater renovation. This is achieved merely by irradiating any part of the resin with light. Within seconds the new material can be completely transformed.

Researchers succeed in controlling multiple quantum interactions in a realistic material Materials with controllable quantum mechanical properties are of great importance for the electronics and quantum computers of the future.

Einstein's "spooky action at a distance" persists even at high accelerations, researchers of the Austrian Academy of Sciences and the University of Vienna were able to show in a new experiment. A source of entangled photon pairs was exposed to massive stress: The photons' entanglement survived the drop in a fall tower as well as 30 times the Earth's gravitational acceleration in a centrifuge.

From powder to solid metal pieces - with a bit of technical trickery, processes that are already used successfully for other materials can now also be used for aluminium.

Researchers at the Institute of Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: they were able to entangle three particles of light in a high-dimensional quantum property related to the "twist" of their wavefront structure.

[ Florian Aigner At the Vienna University of Technology, sophisticated atomchips have been used to create pairs of quantum mechanically connected atom-twins. Until now, similar experiments were only possible using photons. Objects that are well separated in space but still cannot be understood separately belong to the profoundest mysteries of quantum physics.

Prof. Schattschneider from Vienna University of Technology (TU Vienna), together with colleagues from Belgium, is developing a method of producing rotating electron beams and is publishing the technology in the scientific journal "Nature". Manipulating materials with rotating quantum particles: a team from the University of Antwerp and TU Vienna (Professor Peter Schattschneider, Institute of Solid State Physics) has succeeded in producing what are known as vortex beams: rotating electron beams, which make it possible to investigate the magnetic properties of materials.
