  • A Burst of ”Synchronous” Light

    Superlattices under the microscope (white light illumination). Empa

    Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could enable future developments in LED lighting, quantum sensing, quantum communication and future quantum computing. The study has just been published in the renowned journal "Nature".

  • Carbon Nanotubes Couple Light and Matter

    The formation of exciton-polaritons through strong light-matter coupling is a promising strategy for producing electrically pumped carbon-based lasers. Scientists from Heidelberg University and the University of St Andrews (Scotland) have now, for the first time, demonstrated this strong light-matter coupling in semiconducting carbon nanotubes.

    Scientists from Heidelberg and St Andrews work on the basics of new light sources from organic semiconductors. With their research on nanomaterials for optoelectronics, scientists from Heidelberg University and the University of St Andrews (Scotland) have succeeded for the first time to demonstrate a strong interaction of light and matter in semiconducting carbon nanotubes. Such strong light-matter coupling is an important step towards realising new light sources, such as electrically pumped lasers based on organic semiconductors. They would be, amongst other things, important for applications in telecommunications. These results are the outcome of a cooperation between Prof. Dr Jana Zaumseil (Heidelberg) and Prof. Dr Malte Gather (St Andrews), and have been published in “Nature Communications”.

  • First Real-time Test of Li-Fi Utilization for the Industrial Internet of Things

    The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

  • ILA 2018: Automated Lightweight Construction Reduces Weight and Costs

    The Fraunhofer ENAS manufactures printed circuit boards in screen printing on a flexible plastic film. The tracks transmit electrical impulses – for example, to make LEDs glow. Fraunhofer ENAS

    The aircraft of the future flies electrically and autonomously, is feather-light and can be conveniently produced in a fully automated manner. While the electrification and permanent autopilot are still in their infancy, lightweight construction is already indispensable today. Digital manufacturing processes are about to be applied. Fraunhofer will present new automated production technologies for lightweight construction materials at the ILA, the largest innovation trade fair in the aerospace industry, at the Berlin ExpoCenter Airport from April 25 to 29, 2018 (Hall 2, Booth 229).

    Minuscule details with a massive impact: For the first time the research focus Kiel Nano, Surface and Interface Science (KiNSIS) of Kiel University (CAU) will show at the Hannover Messe how cutting-edge research from Kiel produces a range of potential applications for industry. Together with the three other research focus areas at the CAU, KiNSIS will show examples of nanoscience and surface research from the Kiel laboratories in Hall 2, "Research & Technology". Lectures on current research topics complement the programme from 24 to 28 April 2017.

  • Neues Licht dank Nanostrukturen

    Künftig sollen sie das Innere der Handtasche erhellen oder abendliche Jogger aus dem Dunklen hervorheben: Lichtemittierende elektrochemische Zellen, LECs, bieten gegenüber den bekannten LEDs viele Vorteile, aber noch hapert es – ja, am rechten Licht. Bisher sind nur gelb leuchtende LECs geeignet für den realistischen Einsatz. Für neutraleres Licht braucht man aber mindestens eine weitere Lichtfarbe. Forscher vom Center for Nanointegration (CENIDE) der Universität Duisburg-Essen (UDE) konnten nun erstmals die Farbe gezielt verändern und gleichzeitig die Leistungsfähigkeit der LECs steigern.

    7th PV Module Reliability Workshop Sets on the Future of the Solar Energy Market

    On July 6-7, 2017 the Fraunhofer Institute for Solar Energy Systems ISE is hosting the 7th PV Module Reliability workshop. This year the workshop will be held at the Solar Info Center, which is in close proximity to the laboratories of Fraunhofer ISE in Freiburg. The location provides an ideal setting for technical tours and discussions. This year the workshop focuses on the reliability of PV modules and systems, and speakers from throughout the world will be presenting talks related to this theme.

    Automated vehicles have to be able to reliably detect traffic signs. Previous systems, however, have had problems in understanding complex traffic management with different information about speed or the course of the lanes, as mainly occurs on construction sites. Fraunhofer researchers are developing technologies for the real-time interpretation of such signs, which they will present at the CeBIT in Hannover from March 20 to 24, 2017 (Hall 6, Booth B36).

    There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

  • Solarzellen zum Ausrollen

  • Tracking cancer’s signalling pathways

    The picture shows pigmented cells of a malignant melanoma metastasis of the occipital lobe of the brain.

    Malignant melanoma is one of the most common and dangerous types of cancer. Researchers at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) investigated how and why brown pigmented moles turn into malignant melanoma using innovative robot technology. The insights gained can simplify methods of diagnosis in the future; furthermore, they suggest that certain cosmetic products and creams should be avoided. Until now, researchers only knew which genetic mutations were responsible for triggering the transformation of benign pigmented moles into malignant tumours. But little was known about what happens to proteins and signalling pathways when a malignant melanoma develops. The research group led by Prof. Dr. Andreas Baur at FAU’s Translational Research Center (TRC) have now discovered that the ADAM10 signalling pathway is activated during the transformation.
