Die Universität des Saarlandes erreicht im aktuellen Hochschulranking der Wissenschaftsplattform Research.com im Bereich „Business and Management“ bundesweit Platz 21 und weltweit Platz 418. Zudem sind mit den Professoren August-Wilhelm Scheer und Sven Heidenreich zwei Saarbrücker Wirtschaftswissenschaftler im individuellen Wissenschaftlerranking vertreten. [...]

Individuals with high intellectual ability frequently occupy leadership roles across business, science and politics. To date, it has not been definitively established whether a high intelligence quotient correlates with specific political orientations. However, recent research reveals a significant gender-specific distinction: Intellectually gifted men tend to be less conservative than men of average intellectual ability. [...]

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. [...]

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. [...]

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. [...]

The transistor is one of the most important components in electronics. By switching or amplifying electrical signals, transistors make sure that our smartphones, computers and even coffee machines do what we want them to do. A new generation of energy-efficient transistors is now being developed based on thin, lightweight, electrically conducting films. Imagine miniature actuators with their own built-in sensing capability integrated into flexible, film-based circuit boards. [...]

Superconductors – materials that allow electricity to flow with zero electrical resistance – are central to many high-tech applications, from quantum computing and medical technologies to high-performance energy systems. Over the next two and a half years, researchers from Saarbrücken, Dortmund, Eindhoven and Toronto will investigate the fundamental physics of these materials, which are still not yet fully understood, as part of a project funded by the Klaus Tschira Foundation. [...]

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). [...]

Last June, the Saarland state government announced that it would provide over €53 million in funding to establish a Center for Quantum Technologies (QuTe) at Saarland University. Today, QuTe officially launches, with a ceremony to mark the occasion. In addition to Saarland's Minister of Finance and Science Jakob von Weizsäcker and University President Ludger Santen, Astrid Lambrecht, Chair of the Board of Directors of Forschungszentrum Jülich, will also be in attendance.
