Tailor-made X-rays for research and development

Start-up expansion with funding from IFB Hamburg

14-Oct-2021

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 ...

Soft X-ray method promises nanocarrier breakthroughs

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

27-May-2021

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 ...

Why do metal oxide surfaces behave differently?

New research method answers important questions

15-Jan-2021

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 ...

Atom-Billiards with X-Rays

A new Approach to look inside of Molecules

28-Sep-2020

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 ...

Serendipity in the research field of magnetism

Scientists discover new light-matter interaction with which they can write nanometer-sized magnetic structures

22-Apr-2020

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 ...

Classic double-slit experiment in a new light

New X-ray spectroscopy method based on the classical double-slit experiment

22-Jan-2019

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 ...

Scientists observe nanowires as they grow

X-ray experiments reveal exact details of self-catalysed growth for the first time

12-Feb-2018

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 ...

Superradiant nuclei

Scientists measure accelerated emission after excitation by a free electron laser

02-Jan-2018

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 ...

Excitation back and forth: X-ray Rabi oscillations between nuclei observed in coupled cavities

19-Oct-2017

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 ...

Ultrafast snapshots of relaxing electrons in solids

18-Sep-2017

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 ...
