Edges and corners increase efficiency of catalytic converters

X-rays reveal oxide islands on noble metal nanoparticles

28-Mar-2018

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 from the DESY NanoLab watched live as noxious carbon monoxide (CO) was ...

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 ...
