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.

An order of magnitude makes all the difference
An order of magnitude makes all the difference
By Birgit Baustädter In chemical analysis, when electron microscopes reach their limits, the field emission microprobe steps in. With this equipment, taking analysis down to the next level of magnitude is no problem. The wafer-thin black flake shines like a flattened precious stone. The flake is locked in a silver sample container sitting on a clean tray waiting to be pushed into a large machine on the opposite side of the lab.

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.

Battery research at TU Graz: new breakthroughs in research on super-batteries
By Christoph Pelzl Researchers at TU Graz have discovered a means of suppressing singlet oxygen formation in lithium-oxygen batteries in order to extend their useful lives. Additional at the end of the text. Since 2012, Stefan Freunberger of the Institute for Chemistry and Technology of Materials at TU Graz has been working on development of a new generation of batteries with enhanced performance and longer useful lives, and which are also cheaper to produce than current models.

Pit stop for paper bags
By Werner Schandor What does industry-scale cement bag filling have in common with a pit stop in Formula 1? Filling a 25kg paper bag with cement in the factory takes about three seconds, about as long as a pit stop. But packaging and paper manufacturer Mondi reckons this is too long. They asked TU Graz to study the material flow that is at work in this process.

For a longer battery life: Pushing lithium ion batteries to the next performance level
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.

Optimization of alloy materials: Diffusion processes in nano particles decoded
Optimization of alloy materials: Diffusion processes in nano particles decoded
Research team at TU Graz discovers atomic-level processes which can provide new approaches to improving material properties. Aluminium alloys have unique material properties and are indispensable materials in aircraft manufacturing and space technology. With the help of high-resolution electron tomography, researchers at TU Graz have for the first time been able to decode mechanisms crucial for understanding these properties.

Battery-driven research at TU Graz
Battery-driven research at TU Graz
By Birgit Baustädter Batteries are a broad field of research. Energy storage systems of the future should be more powerful, more environmentally friendly, smaller and even safer - work is being done on this at TU Graz. Batteries are many things: cylindrical metal capsules with a plus sign at the top and a minus sign at the bottom, small black packs in our mobile phones, silver buttons in all possible sizes, invisibly integrated in our electric toothbrushes or flat and stacked up in a row in our e-vehicles.

Temperature measurement for Smart Production
Temperature measurement for Smart Production
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).

New Christian Doppler Laboratory
New Christian Doppler Laboratory
By Cecilia Poletti The Christian Doppler Laboratory for Design of High-Performance Alloys by Thermomechanical Processing has recently opened. The leading team, Cecilia Poletti and Friedrich Krumphals, will introduce it. The motivation behind the CD-Laboratory is given by the complexity of simultaneously physical phenomena taking place during industrial processes that involve plastic deformation and heat, as well as during service under thermomechanical loads.

Research trio: TU Graz opens three CD labs simultaneously
Research includes the fabrication of 3D nano-probes, radio-based positioning systems and the porosity of paper at three new Christian Doppler Laboratories to be opened at TU Graz on 25th April. Despite an abundance of CD lab launches at TU Graz, this was the first time it was necessary to open three CD labs at the same time.
