  • New ultra-thin film for interference-free 5G and 6G

    New ultra-thin film for interference-free 5G and 6G

    With the new film made from a special composite material, KIMS is demonstrating how electromagnetic interference in communication systems can be effectively minimised. The film, which is only 0.5 mm thick, absorbs more than 99% of electromagnetic waves in frequency ranges such as 5G, 6G and WiFi. This shielding technology avoids disruptive reflections and offers unrivalled freedom from interference. An advantage that could further optimise the use of modern communication devices and radar systems.

    Absorption instead of reflection
    Conventional shielding materials often rely on reflection, but this is only partially effective. The new type of film, on the other hand, absorbs electromagnetic waves in a targeted manner and thus ensures a high level of interference immunity. This approach prevents waves from bouncing back and interfering with neighbouring systems. The technology is based on a unique crystal structure and a magnetic composite layer that precisely filters frequencies and ensures maximum absorption.

    Flexible and dimensionally stable for a wide range of applications
    The developed film shows high flexibility and dimensional stability, even after thousands of folds. These properties make it ideal for flexible and portable devices such as smartphones and electronics. It also offers reliable shielding and high durability for roll-up screens and other flexible technologies. The film remains dimensionally stable and functional even in demanding applications. Ideal for use in modern, portable devices.

    Optimisation through carbon nanotubes
    A thin carbon nanotube film on the back of the film further increases the shielding performance. With an absorption coefficient of 99.9%, the film ensures that electromagnetic waves do not penetrate to the outside and that interference in various mobile and autonomous applications is minimised. This innovative combination of materials creates reliable shielding, which is particularly in demand in areas with high sensitivity to electromagnetic interference.

    With its high absorption and flexibility, the new KIMS film offers an ideal solution for minimising interference in modern communication technology. It enables better freedom from interference in 5G and 6G networks and could bring ground-breaking improvements in autonomous systems and portable devices – a promising development for future digital infrastructure.

  • PSI researches for low-CO2 cement

    PSI researches for low-CO2 cement

    A research team wants to bring previously unknown processes in the hydration of cement to light. Through a deeper understanding, it wants to pave the way for low-carbon cements. Under the leadership of the University of Malaga, the French University Grenobles Alpes, the European Synchrotron Radiation Facility(ESRF), also located in Grenoble, and the Paul Scherrer Institute are involved in the study.

    According to a PSI statement, the biggest disadvantage of the current proposals for low-carbon cements is the slow hydration kinetics in the first three days. However, it is precisely the understanding of the processes involved in cement production in the early stages that is “crucial”, explains study first author and PhD student at the University of Malaga, Shiva Shirani. “That’s why we developed a method to get a complete picture of the hydration of Portland cement.”

    To do this, the scientists combined complementary experimental approaches at the ESRF and the Swiss Synchrotron Light Source at PSI. Near-field ptychotomography revealed the hydration of commercial Portland cement, according to the release.

    “Understanding the mechanics of the slowest processes will hopefully lead to strategies to reasonably accelerate the hydration of low-carbon cements,” said co-author Professor Miguel A.G. Aranda. This could be done, for example, by using strength-increasing admixtures “to allow early removal of the formwork”.
