First-ever X-ray attosecond experiment on liquids provides new insights into water’s molecular properties

Theorists explain how X-ray measurement freezes hydrogen motion, with implications on other areas of chemistry

19-Feb-2024 - An international team has performed an attosecond-scale experiment at an X-ray free-electron laser on liquid water for the first time, and the results may change our interpretation of water’s behaviour. The experiment team, led by scientist Linda Young from Argonne National Laboratory in the US, ...

Important step for filming chemical reactions

23-Feb-2022 - Exploding a photo subject in order to take its picture? An international research team at the world's largest X-ray laser, the European XFEL, used this “extreme” method to take pictures of complex molecules. With the ultra-bright X-ray flashes generated by the facility, the scientists were able ...

Crystallography for the misfit crystals

Advanced algorithms plus an exceptional X-ray laser can reveal the structures of not-so-neat-and-tidy materials unattainable by other techniques

24-Jan-2022 - Francis Crick, who famously co-discovered the shape of DNA, once said: “If you want to understand function, study structure.” Many decades later, this remains a tenet of biology, chemistry, and materials science. A key breakthrough in the quest for DNA’s structure came from X-ray crystallography, ...

Liquid water at 170 degrees Celsius

X-ray laser reveals anomalous dynamics at ultra-fast heating

18-Sep-2020 - Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic ...

How iron carbenes store energy from sunlight -- and why they aren't better at it

These inexpensive photosensitizers could make solar power and chemical manufacturing more efficient

13-Feb-2020 - Photosensitizers are molecules that absorb sunlight and pass that energy along to generate electricity or drive chemical reactions. They're generally based on rare, expensive metals; so the discovery that iron carbenes, with plain old iron at their cores, can do this, too, triggered a wave of ...

Ultrafast birth of free radicals observed in water

X-ray laser provides unrivalled insight into the first chemical reaction during radiolysis

13-Jan-2020 - Using extremely short X-ray flashes, an international team of researchers has for the first time ever observed details of the ultrafast chemical reaction leading to the formation of aggressive radicals when water is irradiated. The study provides unprecedented insights into the process, which can ...

How molecular footballs burst in an X-ray laser beam

Study shows effect of X-ray flashes on sensitive biomolecules

26-Sep-2019 - An international research team has observed in real time how football molecules made of carbon atoms burst in the beam of an X-ray laser. The study shows the temporal course of the bursting process, which takes less than a trillionth of a second, and is important for the analysis of sensitive ...

First high-speed hard X-ray microscopic movies at a free-electron laser

New technique enables investigation of industrially relevant materials and processes in motion

30-Aug-2019 - A group of researchers has for the first time performed high-speed microscopy using an X-ray laser at the European XFEL. The team produced a super slow-motion movie of a bursting glass capillary with micrometre spatial resolution. The method allows for observations of processes that take place at ...

Grazing light for rapid events

“X-ray streaking” allows ultrafast processes to be followed using a single pulse of light

02-Jan-2018 - An international team of scientists has developed a new experimental method at the FLASH X-ray laser which allows the sequence of events involved in a process to be observed using a single, ultrashort pulse of light from FLASH. Their method is called “X-ray streaking” and enables researchers to ...
