The sharp X-ray vision of DESY´s research light source PETRA III paves the way for a new technique to produce cheap, flexible and versatile double solar cells. The method developed by scientists from the Technical University of Denmark (DTU) in Roskilde can reliably produce efficient tandem plastic solar cells of many metres in length, as a team around senior researcher Jens W. Andreasen reports in the journal Advanced Energy Materials.

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or "soft" X-rays to image structures only five nanometres in size. This resolution, obtained at Berkeley Lab´s Advanced Light Source (ALS), a DOE Office of Science User Facility, is the highest ever achieved with X-ray microscopy.

X-ray microscopy requires radiation of extremely high quality. In order to obtain sharp images instrument and sample must stay absolutely immobile even at the nanometer scale during the recording. Researchers at the Technische Universitaet Muenchen and the Paul Scherrer Institute in Villigen (Switzerland), have now developed a method that relaxes these hard restrictions. Even fluctuations in the material can be visualized. Results are published in Nature.

A novel X-ray microscope at DESY offers the world's sharpest X-ray vision: Thanks to the extraordinary brilliance of DESY's X-ray source PETRA III, this microscope is able to resolve details as small as ten nanometres - which is about ten thousand times thinner than a human hair. Only few facilities worldwide are able to reach a comparable optical resolution.

Minimisation of the geometric restrictions and image infidelities imposed by imperfect physical focussing devices has been the subject of microscopy research for many decades, as has the development of ways to recover information-rich phase data lost by detectors that are sensitive only to illumination intensity.

We know a wide variety of X-ray applications in everyday life. For example, medical X-rays or baggage screening at airports allow non-destructive insights into the interior of objects.

An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. In the Proceedings of the National Academy of Sciences, researchers report progress in applying an approach to "lensless" X-ray microscopy that they introduced one year ago. They have produced the first images, using this technique, of biological cells - specifically the intriguing polyextremophile Deinococcus radiourans.
