X-ray spot on fillet of pork

A team of Swedish and German scientists has been using X-rays at the PETRA III synchrotron light source to study the decomposition of meat. In experiments carried out on fibres taken from fillets of pork, the researchers examined how the quality of the meat was affected by the storage temperature and by parameters affected by the amount of stress experienced by the pigs before slaughter. The results ...

X-ray experiments reveal exact details of self-catalysed growth for the first time

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 of the crystalline nanowires. The findings also provide new approaches to tailoring nanowires with desired properties for specific applications. The scientists, headed by ...

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 rings as they cool – a condition that otherwise does not naturally occur in the material. This behavior allows nanomaterials with new optical and electrical properties, as the ...

Deep insights from diamonds

Diamonds have unparalleled value for geoscientific research. With measurements at DESY's X-ray source PETRA III and elsewhere, an international team including researchers from the University of Bayreuth recently discovered that inclusions of iron-containing garnet are highly oxidized in diamonds that originate at great depths. These tiny pieces of minerals help to explain chemical processes in the ...

1200 participants at the annual users' meeting

The joint meeting of users of DESY's research light sources and the European XFEL X-ray laser once again drew a record number of attendees to Hamburg. Some 1200 participants from nearly 100 institutions from around 30 countries have registered for the three-day event (24-26 January) held at DESY, more than ever before. A particular highlight this ...

Scientists decipher key principle behind reaction of metalloenzymes

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team, including researchers from DESY,  has worked out the details of how important bioinorganic electron transfer systems operate. Using a combination of very different, time-resolved measurement methods at DESY's X-ray source PETRA III and other facilities, the scientists were able to show ...
