Gas-based Sono-photonics - Replacing traditional optical components with air and sound
We’re excited to share our new video on gas-based sono-photonics – a pioneering approach that replaces traditional optical components with air and sound. At the forefront of this innovation is Christoph Heyl and his team at DESY, demonstrating how sound waves in gas can be used to manipulate light in high-power laser systems – dynamically, contact-free, and without...-

Optical components made of air: Gas-based sono-photonics as a new platform technology
Using ultrasound to produce optical gratings from layers of air of different densities to control light - this has been achieved by the DESY Ultrafast Photonics research group together with TU Darmstadt and the ultrasound device manufacturer Inson GmbH. The project was supported by Hi-Acts and funded by the Carl-Zeiss-Stiftung with 750,000 €.-

Vakuum begreifen: Luftwiderstand
Warum fallen manche Dinge langsamer als andere? Das hat nichts mit Unterschieden aufgrund der Schwerkraft zu tun, sondern damit, dass die Luft um uns herum die fallenden Gegenstände zurückdrängt. In diesem Video sehen wir uns an, wie die Luft um uns herum fallende Gegenstände beeinflusst - und das alles mit Hilfe einer Vakuumröhre!-

Ultrafast electronic dynamics of charge transfer in TiO2 systems induced by light absorption
Quantum dots help to capture light so that it can trigger electrochemical processes. Here, Friedrich Roth from the TU Bergakademie Freiberg is investigating quantum dots made of silver (Ag), indium (In) and sulphur (S) in combination with zinc sulphide on titanium dioxide surfaces at the SXP experiment station of the European XFEL in Schenefeld near Hamburg. The advantage of this combination...-

Investigation of cavitation damage of soft matter and biological tissue studied through time-resolved X-ray imaging at European
At the MID (Materials Imaging & Dynamics) instrument, Tim Salditt from the Georg-August-Universität Göttingen is investigating damage to biological tissue or soft matter that can be caused by so-called cavitation. This refers to the collapse of tiny bubbles. This can lead to damage, for example, during medical treatments such as the disintegration of bladder or kidney stones with highly...-

Understanding fast phenomena of fluid transport in porous media using MHz X-ray microscopy
Patrick Huber and Stella Gries from Hamburg University of Technology and DESY are investigating how liquids are distributed in thin layers of porous silicon. He is particularly interested in the capillary forces that cause liquids to rise upwards in small, interconnected tubes, even against gravity. These processes take place so fast that they cannot be detected using standard synchrotron...-
