Team uses innovative X-ray imaging at DESY to provide proof for the first time
24-Dec-2021
Using DESY's X-ray lightsource PETRA III, an interdisciplinary research team led by the University of Göttingen and Hannover Medical School (MHH) has detected significant changes in the heart muscle tissue of people who died from Covid-19. Damage to lung tissue has been the research focus in this ...
Analysis points the way to more durable iridium electrodes
23-Dec-2021
Green hydrogen is expected to play a central role in the energy industry of the future: Among other things, it can replace oil and gas as energy carriers and also enable emission-free production of steel and cement. For an efficient hydrogen economy, however, the production of the ...
Artificial intelligence affords unprecedented insights into how biomolecules work
08-Nov-2021
A new analytical technique is able to provide hitherto unattainable insights into the extremely rapid dynamics of biomolecules. The team of developers, led by Abbas Ourmazd from the University of Wisconsin–Milwaukee and Robin Santra from DESY, is presenting its clever combination of quantum ...
X-rays reveal compositional changes on active surface under reaction conditions
05-Oct-2021
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
30-Sep-2021
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 ...
X-ray laser European XFEL captures rapid reaction of bacterial enzyme
30-Sep-2021
Using the X-ray laser European XFEL an international team of researchers, including scientists from DESY, has successfully filmed a reaction step that is important for the development of antibiotic resistance. The molecular film captures the very rapid reaction of the enzyme beta-lactamase from ...
DESY team demonstrates first Terahertz enhanced electron diffractometer
19-Aug-2021
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
16-Aug-2021
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
13-Aug-2021
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, ...
Existing active substances bind to key virus protein
07-Apr-2021
A team of researchers has identified several candidates for drugs against the coronavirus SARS-CoV-2 at DESY´s high-brilliance X-ray lightsource PETRA III. They bind to an important protein of the virus and could thus be the basis for a drug against Covid-19. In a so-called X-ray screening, the ...
