Embryology of 609 million-year old Caveasphaera. These are computer models based on X-ray tomographic microscopy of the fossils, showing the successive stages of development.

Animal embryos evolved before animals

Detailed characterization of cellular structure and development of exceptionally preserved ancient tiny fossils from South China by synchrotron based X-ray tomographic microscopy at TOMCAT led an international team of researchers from the University of Bristol and Nanjing Institute of Geology and Palaeontology to the discovery that animal-like embryos evolved long before the first animals appear in the fossil record.

A fast and precise look into fibre-reinforced composites

Media Releases Matter and Material Research Using Synchrotron Light

Researchers at the Paul Scherrer Institute PSI have developed a new process with which fibre-reinforced composite materials can be precisely X-rayed. This could help to develop better materials with novel properties.

Sample rotation stage for high-speed tomography

World record in time-resolved tomography

Researchers from the Helmholtz Zentrum Berlin (HZB) and the TOMCAT beamline have achieved a new world record in time-resolved tomography by measuring over 200 tomographies per second during heating of an evolving aluminium metal foam.

Virtual lens improves X-ray microscopy

Media Releases Matter and Material Research Using Synchrotron Light

A method developed by PSI researchers makes X-ray images of materials even better. The researchers took a number of individual images while moving an optical lens. From these, with the help of computer algorithms, they generated one overall image.

Soft-tissue evidence for homeothermy and crypsis in a Jurassic ichthyosaur

Synchrotron-based X-ray tomographic microscopy of melanophores (skin pigment cells) of an amazingly well preserved 180 million years old ichtyosaur (extinct marine reptile similar to whales) contributed in a multidisciplinary investigation to the new findings published today in Nature.

Single shot grating interferometry demonstrated using direct conversion detection

Researchers at the Paul Scherrer Institute's Swiss Light Source in Villigen, Switzerland, have developed an X-ray grating interferometry setup which does not require an analyzer grating, by directly detecting the fringes generated by the phase grating with a high resolution detector. The 25um pitch GOTTHARD microstrip detector utilizes a direct conversion sensor in which the charge generated from a single absorbed photon is collected by more than one channel. Therefore it is possible to interpolate to achieve a position resolution finer than the strip pitch.

Watching lithium move in battery materials

In order to understand limitations in current battery materials and systematically engineer better ones, it is helpful to be able to directly visualize the lithium dynamics in materials during battery charge and discharge. Researchers at ETH Zurich and Paul Scherrer Institute have demonstrated a way to do this.
