X-rays reveal compositional changes on active surface under reaction conditions
A DESY-led research team has been using high-intensity X-rays to observe a single catalyst nanoparticle at work. The experiment has revealed for the first time how the chemical composition of the surface of an individual nanoparticle changes under reaction conditions, making it more active. The ...
Analysis helps to understand fragmentation of catalyst particles in ethylene polymerisation
An X-ray study at DESY is pointing the way towards a better understanding of plastics production. A team led by Utrecht University investigated so-called Ziegler-type catalysts, the workhorses in the world's polyethylene and polypropylene production, at DESY's X-ray source PETRA III. As the ...
The future is moving in: Start-up Labs Bahrenfeld, a project jointly managed by DESY, the University of Hamburg and the City of Hamburg, is the new place for science entrepreneurship on DESY’s research campus. The innovation centre for deep-tech start-ups will also enhance the profile of the ...
DESY team demonstrates first Terahertz enhanced electron diffractometer
Scientists at DESY have built a compact electron camera that can capture the inner, ultrafast dynamics of matter. The system shoots short bunches of electrons at a sample to take snapshots of its current inner structure and is the first such electron diffractometer that uses Terahertz radiation ...
Precise orientation affects shape, size and behaviour
Nanoparticles that make up catalysts can arrange themselves in slightly different ways, and behave significantly differently as a result. This is revealed by an X-ray study of palladium nanoparticles carried out at DESY Nanolab and PETRA III. The study has been published in the journal ACS Nano ...
X-ray study reveals how lead sulphide particles self-organise in real time
The structure adopted by lead sulphide nanoparticles changes surprisingly often as they assemble to form ordered superlattices. This is revealed by an experimental study that has been conducted at DESY’s X-ray source PETRA III. A team led by the DESY scientists Irina Lokteva and Felix Lehmkühler, ...
Scientists observe vibrational dynamics of organic acid molecules on iron oxide surface
A Hamburg research team is paving the way for new methods of producing tailor-made materials: for the first time, the scientists from DESY NanoLab and the Hamburg University of Technology (TUHH) have deciphered the collective arrangement of organic acid molecules on an iron oxide surface at the ...
A pinch of nitrogen and artificial intelligence are moving laser plasma acceleration a big step closer to practical applications
The LUX team at DESY is celebrating not just one but two milestones in the development of innovative plasma accelerators. The scientists from the University of Hamburg and DESY used their accelerator to test a technique that allows the energy distribution of the electron beams produced to be kept ...
Innovative time-resolved study reveals network formation and dynamics of proteins
Using DESY's X-ray light source PETRA III, a research team has analysed the structural changes in eggs during cooking. The study shows how the proteins in chicken egg whites unfold and crosslink during heating to form a solid structure. The innovative investigation method is interesting for the ...
New world record in the temporal resolution achieved using GISAXS, a surface-sensitive scattering technique
For the first time, a team of scientists has succeeded in capturing in real time the first few milliseconds in the life of a gold coating as it forms on a polymer. The team used DESY’s high-brilliance X-ray source PETRA III to observe the earliest stages in the growth of a metal-polymer hybrid ...
