Nitratdünger sorgt für bessere Ernten, belastet aber auch unser Trinkwasser. Bisherige Filtrierungsverfahren verlagern das Problem oft nur: Das Nitrat wird zwar aus dem Wasser entfernt, ist aber nach wie vor in der Welt. Wissenschaftlerinnen und Wissenschaftler der Universität des Saarlandes und der Universität Graz suchen nun nach einem Weg, Nitrat nicht nur aus dem Wasser zu filtern, sondern es in derselben Membran auch chemisch in harmlose Stoffe, im Idealfall Stickstoff, umzuwandeln.

Oskar Staufer and his team are developing novel biomaterials to better understand and control immune processes. His interdisciplinary research brings together biophysics with biomaterials and immunology. Oskar Staufer has been leading the Immuno-Materials Emmy Noether Group at the INM – Leibniz Institute for New Materials since 2022. Saarland University and INM have now jointly appointed Oskar Staufer Professor of Experimental Biophysics. [...]

Smart implants that not only stabilize a fracture but also monitor the healing process from day one – and deliver targeted support when required – are currently being developed at Saarland University by a team of engineers, medical researchers and computer scientists. The engineering team led by Paul Motzki is contributing shape‑memory micro‑actuators with integrated sensing capabilities, while Bergita Ganse and her research group provide the medical expertise in fracture healing. [...]

An ultrathin silicone film being developed at Saarland University enables pumps to operate without motors, without compressed air and without lubricants or external sensors. These film-based pumps can be switched on and off as needed and integrated into designs previously thought impossible. [...]

Visitors to this year’s Hannover Messe can experience a sudden drop in temperature at first hand – all brought about by simply stretching a metal alloy and then releasing it again. The underlying elastocaloric technology offers a cleaner, greener alternative to traditional cooling and heating systems. Professor Paul Motzki and his team at Saarland University are key players in the field and are driving developments ever closer towards real-world applications. [...]

A sponge is more elastic than an eraser: if you deform it, it returns to its original shape. This phenomenon is often crucial for the development of new materials. Physicists at Saarland University have now demonstrated in an experiment that the elasticity of a material decreases significantly when it is enclosed in pores measuring just a few millionths of a millimetre. This effect is all the more notable the smaller the diameter of the pores. [...]

Hannover Messe: Electric motors are getting smaller, lighter and more powerful – and that makes overheating a growing risk. A research team led by Professor Matthias Nienhaus at Saarland University has developed an AI-assisted method of determining the temperature distribution inside a running electric motor in real time – and without the need for additional hardware. The team will be showcasing the technology at the Hannover Messe (20–24 April). [...]

Thinking ahead is a skill taught to learner drivers from the outset – and the intelligent wheels being developed by Professor Matthias Nienhaus’s research team at Saarland University seem to do just that. By anticipating where the user intends to go they can provide a helping push at just the right moment, offer stability when cornering and make manoeuvring under load easier. The team will be showcasing the latest generation of their smart wheel technology at the Hannover Messe. [...]
