Unique close-up of the dynamics of photosynthesis

10.05.2010
Researchers at the University of Gothenburg, Sweden, have managed, with the help of an advanced X-ray flash, to photograph the movement of atoms during photosynthesis – an achievement that has been recognised by the journal Science.

The European Synchrotron Radiation Facility in Grenoble is home to one of the world’s most advanced particle accelerators, whose pulsing X-ray beams are used by researchers to photograph and study life’s tiniest components: atoms, molecules and proteins.

Using the special X-ray camera, researchers can depict the position of atoms in a molecule and obtain a three-dimensional image of something that is smaller than a billionth of a metre. Researchers at the Department of Chemistry at the University of Gothenburg and at Chalmers University of Technology have now used this advanced technology to photograph the dynamics of life's most fundamental system: photosynthesis.

The focus of the study was a protein which is central to the conversion of light to chemical energy during photosynthesis, and which process the Gothenburg researchers have been the first to (successfully photograph) (capture?). The X-ray image shows how the protein temporarily stores the light energy immediately before a chemical bond forms – a movement that takes place on a scale of less than a nanometre.

The photograph is not only a fascinating snapshot of the very core of life, but could also be used in the solar panels of the future, where researchers hope to be able to imitate the sophisticated energy conversion of photosynthesis.

The photography is highlighted in an article in the next issue of Science.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
