Start-up expansion with funding from IFB Hamburg
The high-tech Spin-Off TXproducts, founded in April 2021 on the DESY campus in Hamburg, will receive funding from Investitions- und Förderbank Hamburg (ifb). TX stands for "Tailored X-Ray", and the company develops solutions for customizing synchrotron X-rays beams for experiments at large-scale ...
Before the huge potential of tiny nanocarriers for highly targeted drug delivery and environmental clean-up can be realized, scientists first need to be able to see them
Currently researchers have to rely on attaching fluorescent dyes or heavy metals to label parts of organic nanocarrier structures for investigation, often changing them in the process. A new technique using chemically-sensitive "soft" X-rays offers a simpler, non-disruptive way of gaining insight ...
New research method answers important questions
Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface. This phenomenon has been known for a long time, but until now it has ...
A new Approach to look inside of Molecules
In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer ...
Scientists discover new light-matter interaction with which they can write nanometer-sized magnetic structures
In cooperation with Chinese researchers from the Chinese Academy of Sciences and others, German researchers from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart have for the first time ever created individual skyrmions in a magnetic layer using soft X-rays. In numerous ...
New X-ray spectroscopy method based on the classical double-slit experiment
An international research team led by physicists from Collaborative Research Centre 1238, 'Control and Dynamics of Quantum Materials' at the University of Cologne has implemented a new variant of the basic double-slit experiment using resonant inelastic X-ray scattering at the European ...
X-ray experiments reveal exact details of self-catalysed growth for the first time
At DESY's X-ray source PETRA III, scientists have followed the growth of tiny wires of gallium arsenide live. Their observations reveal exact details of the growth process responsible for the evolving shape and crystal structure of the crystalline nanowires. The findings also provide new ...
Scientists measure accelerated emission after excitation by a free electron laser
An international team of scientists has verified a prediction about the quantum-mechanical behaviour of resonant systems made more than 50 years ago. In experiments at the Japanes X-ray laser SACLA and at the European Synchrotron Radiation Facility ESRF in France, the group led by Aleksandr ...
X-rays interact weakly with matter. This is their greatest strength for many applications, but also a fundamental weakness for others. In particular the fields of nonlinear optics and quantum optics, mainstays for both fundamental science and technological applications with light, require a ...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a ...
