Innovation Award Rhineland-Palatinate for the Spintronics Technology Platform STeP


Award for outstanding cooperation in knowledge transfer between cutting-edge research and companies

The research project Spintronics Technology Platform in Rhineland-Palatinate (STEP) has obtained the Innovation Award Rhineland-Palatinate 2015 (Innovationspreis Rheinland-Pfalz 2015) in the category Cooperation. The joint project of the TU Kaiserslautern and the University of Mainz (JGU) has been set up with the participation of the company Sensitec in its facilities in Mainz. STeP is technology platform to quickly and directly translate scientific findings from physics to industrial standards and it is designed especially to make new technologies accessible to small and medium businesses. The partners have achieved significant progress in the development of novel magnetic sensors. "These new, energy-efficient sensors are primarily increasingly required for the establishment of industry 4.0 or the Internet of Things" as stated by the Innovation Award.

"The research project is a shining example of the great potential that lies in the cooperation between science and industry. The transfer of the latest scientific findings into practice will help our companies in the State to be competive in an international envireonment," said Minister of Economic Affairs Eveline Lemke.

The prize is awarded annually by the Minister of Economy, Climate Change, Energy and Regional Planning of Rhineland-Palatinate, Eveline Lemke, in cooperation with the working committees of the chambers of Commerce and Handcraft of the State. The award goes to particularly innovative players in Rhineland-Palatinate in recognition of their achievements and commitment to innovation in the country's economy. The award is endowed with 8,000 euros.

Collaborative Research Center SFB/TRR 173 SPIN+X approved

 

 

The Deutsche Forschungsgemeinschaft (DFG) has approved funding for the SFB/Transregio 173 "SPIN+X: Spin in its collective environment“. This initiative has been initiated by the TU Kaiserslautern jointly with Johannes Gutenberg University Mainz. Project start for the first four-year funding period is January 1, 2016. The inter-disciplinary SFB/Transregio 173 SPIN+X combines the expertise of research groups in physics, chemistry, and mechanical and process engineering to form a coherent platform dedicated to the rapidly growing discipline of Advanced Spin Engineering. Our research group contributes three projects to this exciting new funding program.

Andrii Chumak receives ERC Starting Grant

Our co-worker Dr. Andrii Chumak receives an ERC Starting Grant from the European Research Council for his project “Nano-Scale Magnonic Circuits for Novel Computing Systems”. This 1.5 Mio Euro grant is the most-prestigious grant the European Commission awards to young scientists. With this grant Andrii will build his own research team including a new Brillouin light scattering laboratory.

Our very best congratulations!
