X-ray insights may enable better plastics production

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 ...

Unexpected twist of catalytic nanoparticles

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 ...

DESY X-ray lightsource identifies promising candidates for COVID drugs

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 ...

Bacteria needle under the electron microscope

Researchers watch injectisome of gram-negative bacteria in action for the first time

15-Mar-2021

For the first time, researchers have revealed the syringe-like type-III secretion system of Gram-negative bacteria in action. In the research study, published in Nature Communications, the group of Thomas Marlovits from the Centre for Structural Systems Biology (CSSB) at the DESY campus provides ...

Researchers watch nanomaterials growing in real time

New world record in the temporal resolution achieved using GISAXS, a surface-sensitive scattering technique

17-Feb-2021

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 ...

Supermicroscope for Protein Crystals

Combination of techniques locates microcrystals for structural analysis

26-Nov-2020

A novel kind of microscope is able to detect tiny protein crystals, which are beyond the imaging power of even modern light microscopes. The innovative technique relies on various non-linear optical effects to image even nanocrystals, which are increasingly being used for protein structure ...

Searching for the chemistry of life

Study shows possible new way to create DNA base pairs

06-Oct-2020

In the search for the chemical origins of life, researchers have found a possible alternative path for the emergence of the characteristic DNA pattern: According to the experiments, the characteristic DNA base pairs can form by dry heating, without water or other solvents. The team led by Ivan ...

Two colour technique reveals how X-ray lasers damage biomolecules

Step to a fuller understanding of how X-ray flashes modify the structure of proteins

03-Jun-2020

X-ray lasers can reveal the spatial structures of biomolecules that are hard to come by with other methods. However, the intense X-ray flashes vaporise the samples almost immediately. An international team of scientists has now followed how this radiation damage spreads in biomolecules to ...
