09.10.2019 Bessel prize-winner at the TU Ilmenau
One of this year's winners of the Alexander von Humboldt Foundation's prestigious Friedrich Wilhelm Bessel Research Award, Professor Lan Yang from Washington University in St. Louis, USA, will spend her associated stay abroad at the Technical University of Ilmenau starting in 2020.

09.07.2019 Project »ZO.RRO« - Zero Carbon Cross Energy System
After the first phase of the energy revolution with the establishment of renewable energies was completed and their expansion progressed worldwide, we have now entered the second phase. This phase not only includes the phasing out of fossil fuels in the power plant park, but above all the provision of flexibility in a system with cross-sector grid management, which is characterized by fluctuating power generation through wind and solar energy, i.e. the demand for energy must be adapted to the availability of the energy.

14.05.2019 Hydrogen produced from sunlight: New record efficiency in direct solar water splitting
In a sustainable energy system, hydrogen will play a central role as a storage medium and as fuel for maintaining mobility. An international team of researchers has succeeded in increasing the efficiency of direct solar water splitting, the first step of natural photosynthesis, to over 19% by combining a tandem solar cell from III-V semiconductors with rhodium nanoparticles and crystalline titanium dioxide [1]. Teams from the TU Ilmenau, the Fraunhofer Institute for Solar Energy Systems, the California Institute of Technology and the University of Cambridge participated in this research.[more]

11.04.2019 Smart acoustic sensing based on artificial hair cells
The goal of this project is to build a smart sensing system for sound detection which is capable of information processing and (self-) adaption to the current environment. The underlying principles are inspired by the sound detection in the (human) inner ear, the cochlea.[more]

01.03.2019 Development and application of new forward solutions in Lorentz force eddy current testing
The detection and evaluation of defects in solid conductive materials is important in quality assurance. Non-destructive testing is a quality control tool widely used in the metal industry for inspecting electrically conductive materials. One of the most extensively used techniques in the non-destructive testing inspection is the eddy current testing. Here, an alternating current produces a time-varying magnetic flux density, which according to the Faraday's electromagnetic induction, induces currents in an electrical conductor. Variations in electrical conductivity inside an object under test or the presence of defects cause changes in eddy currents and consequently a change in the impedance of the coil. Measuring this impedance, a defect can be detected. However, due to the skin effect, eddy current testing is limited to surface cracks and cracks close to the surface.

07.02.2019 Successful funding programme for young women scientists
There are not enough female professors. What can be done about the fact that so many leave the universities after their doctorates? Do scholarships help to keep more women in science? In 2018, five young ladies were awarded scholarships under the programme for promoting young female scientists at Technische Universität Ilmenau. The funding was provided by the Thuringian Ministry for Economic Affairs, Science and Digital Society (TMWWDG) and TU Ilmenau.

04.09.2018 Precise calibration system for micro- and nano-force sensors
Over the past 15 years the Raster-Kraft-Mikroskopie (atomic force microscopy) has developed into a standard analytical method in micro- and nanosystems technology and contributes significantly to the rapid development in nanotechnology. It allows microscopic images in an enlargement of several million times and thus the visualization of yet undiscovered details. The centerpiece of the atomic force microscope is the cantilever, consisting of a measuring tip which is located with at a length of 100… 400 μm at the end of a flexible cantilever. When the spring stiffness of such a cantilever is calibrated, i.e. its force-deflection-characteristic, it can also be used for measuring the smallest forces on a microscopic scale.[more]
