    Four scientists from Freiburg have succeeded for the first time to simulate the localized growth of silicon crystals using shear-induced amorphization and recrystallization. In the future, experts could use this concept to tailor crystalline silicon structures for nanotechnology applications, such as nanoelectronics. “Triboepitaxy”, the fundamental idea that could make this possible, is presented by the team in the journal “Physical Review Letters”.

    Fuel cells are typically applied to generate electrical energy from hydrogen or methanol. Nanoscale catalysts get the process going - but until now, the quality of these materials has varied significantly. The CAN research division of the Fraunhofer Institute for Applied Polymer Research IAP eliminated these problems: With an optimized catalyst and continuous, reproducible production process with very good control over the material properties.

    Metal processing with lasers and plasma releases many different pollutants into the ambient air. The Fraunhofer Institute for Material and Beam Technology IWS, together with partners, has developed a filter system that efficiently removes these substances from the air. The filter can be adapted to the various materials and substances released in each case. In the future, the technology will be used in other applications, such as additive manufacturing.

    Conventional processes for manufacturing battery electrodes involve mostly toxic solvents and require a lot of space and energy. This is not the case with DRYtraec® – a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology IWS. The technology is environmentally friendly and cost effective and can be used on a large scale, giving it the potential to revolutionize the manufacturing of battery electrodes.

    In a disaster, whether floods, earthquakes or hurricanes, every second counts in providing humanitarian aid to those in need. The teams of aid organisations are under immense time pressure to find their way in devastated areas. A team from the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern is developing software that will get humanitarian aid to the right destination faster. To do this, they use drone images that are evaluated in real time with artificial intelligence (AI).

    In combustion engines, in plain bearings and in aerospace: diamond-like carbon coatings (DLC) reduce friction and wear in frictional contacts. In most cases, the lubricants used in bearings and engines contain the additive zinc dialkyl dithiophosphate (ZDDP), which in turn protects steel surfaces against wear. Unfortunately, it can attack the DLC layer, leading to premature failure. Researchers at the Fraunhofer IWM have discovered how the antagonistic interaction between the two substances occurs. In the journal Nature Communications, they explain why DLC layers can also be too hard in combination with ZDDP.

    In addition to the classical applications for solar cells on roofs and open spaces, photovoltaic devices can also be used with laser light for efficient power transmission. At the 48th IEEE Photovoltaic Specialists Conference, researchers from the Fraunhofer Institute for Solar Energy Systems ISE recently presented how they were able to achieve a record conversion efficiency of 68.9% with a photovoltaic cell under monochromatic laser light. For this, the research team used a very thin photovoltaic cell made of gallium arsenide and applied a highly reflective, conductive mirror on the backside.

  • A sustainable society with climate-neutral processes requires significant adjustments in the value chains, which are only possible through innovations. Seven Fraunhofer Institutes are pooling their expertise in the lighthouse project "Waste4Future" to develop new solutions for this goal, from the raw material base to material flows and process engineering right to the end of a product's life cycle. In particular, they want to increase energy and resource efficiency in the use of plastics and thus pave the way for a chemical industry that requires fewer fossil raw materials and produces fewer emissions.

  • India's cities are growing rapidly and need an efficient infrastructure for supplying water and disposing of wastewater. Many German companies offer innovative solutions in this area, but often struggle to find access to the Indian market. Thanks to its extensive experience with projects in India, the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB can help to bridge the gap between demand and supply. To this end, the institute is now setting up the innovation network "AQUA-Hub" to mediate between German water technology suppliers and the Indian market.
