World’s strongest bio-material beats steel and spider silk

DESY scientists have produced the strongest bio-material that has ever been made. As compare to strongest bio-material ever known- spider silk, this artificial, but bio-degradable cellulose...

World’s fastest water heater

Using X-ray Free-Electron Lasers, scientists have opened up way in structural biology, enabling imaging of biomolecules and dynamics that were impossible to access with...
On the ultra-thin, extremely regular layer of graphene, the fibrils align themselves in parallel in large domains. The intense X-ray light from the X-rax free-electron laser LCLS at the SLAC National Accelerator Center enabled the researchers to gain partial information about the fibril structure from ensembles of just a few fibrils.

X-ray laser opens new view on Alzheimer proteins

DESY scientists have used a powerful X-ray laser to gain insights into the structure of different amyloid samples. Using x-ray laser, they discovered filamentous biomolecules...
Scheme of the experiment: An autocorrelator developed at DESY splits the ultrashort X-ray laser pulses into two equal intensity pulses which arrive with a tunable delay at the sample. The speckle pattern of the sample is collected in a single exposure of the 2-D detector (picture: W. Roseker/DESY).

Freeze-framing nanosecond movements of nanoparticles

A collaboration of scientists from DESY, the Advanced Photon Source APS, and National Accelerator Laboratory SLAC, both in the USA have created and incorporated another technique...

High-energy X-ray technique offers 3D images of intact biological cells

Imaging the structures of biological cells on the nanometer scale usually requires X-rays, as their short wavelengths allow to resolve the fine details. However, X-rays...

New Swiss army knife for electron beams

Scientists have created a miniature particle accelerator for electrons that can perform four different functions at the push of a button. The device that...
With increasing oxygen (red) concentration, an oxide sandwich forms on the surface of the metallic nanoparticles, inhibiting the desired reaction of carbon monoxide to carbon dioxide. At the edges, however, the oxide sandwich brakes up, leaving free active sites for catalysis. The more edges the nanoparticles posses, the more efficient will the catalytic converter work.

Edges and corners increase efficiency of catalytic converters

Catalytic converters for cleaning exhaust emission are more proficient when they utilize nanoparticles with numerous edges. This is one of the discoveries of an...
