Novel nozzle saves crystals

Double flow concept widens spectrum for protein crystallography

21-Mar-2017

Thanks to an innovative nozzle, scientists can now analyse more types of proteins while using fewer of the hard-to-get protein crystals. The nozzle can reduce protein consumption eightfold in serial X-ray crystallography experiments, as the team of inventors, headed by DESY scientist Saša Bajt ...

Laser metronome achieves record synchronization

First attosecond timing in a kilometre-wide laser-microwave network

13-Jan-2017

Scientists at DESY have set up the world's most precise ‘metronome’ for a kilometre-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a quintillionth of a second, or a millionth of a millionth of a millionth ...

Why van Gogh's Sunflowers are wilting

Analysis of chrome based colors at DESY

22-Oct-2015

Vincent van Gogh (1853-1890) is famous for his use of bright yellow colours. The Dutch painter used so-called chrome yellows, a class of compounds consisting of lead, chromium and oxygen. "There are different shades of the pigment, and not all of them are photochemically stable over time," ...
