X-ray laser opens new view on Alzheimer's proteins

A new experimental method permits the X-ray analysis of amyloids, a class of large, filamentous biomolecules which are an important hallmark of diseases such as Alzheimer's and Parkinson's. An international team of researchers ...

Scientists create 'Swiss army knife' for electron beams

DESY scientists have created a miniature particle accelerator for electrons that can perform four different functions at the push of a button. The experimental device is driven by a terahertz radiation source and can accelerate, ...

Edges and corners increase efficiency of catalytic converters

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY's X-ray source PETRA III. A team of scientists ...

Scientists observe nanowires as they grow

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 ...

Liquid crystal molecules form nano rings

At DESY's X-ray source PETRA III, scientists have investigated an intriguing form of self-assembly in liquid crystals: When the liquid crystals are filled into cylindrical nanopores and heated, their molecules form ordered ...

Clay mineral waters Earth's mantle from the inside

The first observation of a super-hydrated phase of the clay mineral kaolinite could improve our understanding of processes that lead to volcanism and affect earthquakes. In high-pressure and high-temperature X-ray measurements ...

X-ray Rabi oscillations between nuclei observed in coupled cavities

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 ...

Microwaves reveal detailed structure of molecular motor

A team of scientists has used microwaves to unravel the exact structure of a tiny molecular motor. The nano-machine consists of just a single molecule, made up of 27 carbon and 20 hydrogen atoms (C27H20). Like a macroscopic ...
