3D nanostructure of a bone made visible

Media Releases Biology Research Using Synchrotron Light Human Health

Bones are made up of tiny fibres that are roughly a thousand times finer than a human hair. Researchers at the Paul Scherrer Institute PSI have developed a new computer-based algorithm with which they were able to visualize the localised order and alignment of these nanostructures inside an entire piece of bone for the first time.

Matter and Material Research Using Synchrotron Light

In a series of experiments at the Swiss Light Source SLS, physicists from the Paul Scherrer Institute PSI have discovered a particle, the existence of which was predicted eighty-six years ago. It is a member of the particle family that also includes the electron, the carrier of electrical currents. The particle now discovered is massless and can exist only within a special class of materials known as Weyl semi-metals.

Structure of concrete disease solved

Media Releases Research Using Synchrotron Light Matter and Material

When bridges, dam walls and other structures made of concrete are streaked with dark cracks after a few decades, the culprit is the so-called the concrete disease. Researchers from the Paul Scherrer Institute PSI and Empa have now solved the structure of the material produced in these cracks at atomic level - and have thereby discovered a previously unknown crystalline arrangement of the atoms.

Tiny magnets mimic steam, water and ice

Media Releases Materials Research Matter and Material Research Using Muons Micro- and Nanotechnology

Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state.

The key to charging a lithium-ion battery rapidly

Media Releases Energy and Environment Research Using Synchrotron Light

Lithium iron phosphate batteries are very durable and can be charged relatively quickly. Researchers from the Paul Scherrer Institute (PSI), ETH Zurich and Japanese car manufacturer Toyota reveal the reasons for these properties in a new study. The findings were made possible thanks to measurements using a new method at the Swiss Light Source (SLS) at PSI.

In search of the smallest bit

Matter and Material Research Using Synchrotron Light Materials Research

For increasingly compact storage media, magnetic areas – the memory bits – also need to become smaller and smaller. But just how small can a magnet be? Frithjof Nolting and his colleagues at the Paul Scherrer Institute investigate the surprising phenomena in the field of nanomagnetism.

Seven nanometres for the electronics of the future

Micro- and Nanotechnology Materials Research Matter and Material Research Using Synchrotron Light

Researchers from the Paul Scherrer Institute have succeeded in creating regular patterns in a semiconductor material that are sixteen times smaller than in today’s computer chips. As a result, they have taken an important step closer towards even smaller computer components. Industry envisages structures on this scale as the standard for the year 2028.

Together, not alone

Research Using Synchrotron Light SwissFEL SwissFEL Experiments Human Health

Decoding biomolecules at SwissFEL and SLS
Proteins are a coveted but stubborn research object. A method developed for x-ray free-electron lasers and PSI’s future SwissFEL should now help researchers to make good headway in this field. It involves x-raying many small, identical protein samples consecutively at short intervals, thereby avoiding the main problem that protein research has faced thus far: producing samples in a sufficient size.

From inside an eggshell

Research Using Synchrotron Light Large Research Facilities

Tiny cavities inside eggshells supply the materials that stimulate and control the shell’s growth. Using a novel imaging technique, researchers from the Paul Scherrer Institute (PSI), ETH Zurich and the Dutch FOM Institute AMOLF have succeeded in depicting these voids in 3D for the first time. In doing so, they lift an old limitation of tomographic images and hope that one day medicine will also benefit from their method.

Interview with Gabriel Aeppli
Gabriel Aeppli has been head of synchrotron radiation and nanotechnology research at PSI since 2014. Previously, the Swiss-born scientist set up a leading research centre for nanotechnology in London. In this interview, Aeppli explains how the research approaches of the future can be implemented at PSI's large research facilities and talks about his view of Switzerland.

Split x-ray flash reveals rapid processes

SwissFEL SwissFEL Technology Micro- and Nanotechnology

SwissFEL, PSI’s x-ray laser, is to render the individual steps of very rapid processes visible. A new method will facilitate especially precise experiments: the individual x-ray flashes are split into several parts that arrive at the object under examination one by one. The principle of the method harks back to the ideas of the earliest high-speed photography.

Nanometres in 3D

Media Releases Matter and Material Research Using Synchrotron Light Micro- and Nanotechnology

Scientists at the Paul Scherrer Institute and ETH Zurich have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.

SwissFEL SwissFEL Experiments Large Research Facilities

For many years, PSI researchers have been testing experimental methods that will provide insights into novel materials for electronic devices. Using a special trick to make the Swiss Light Source (SLS) at PSI generate light with similar properties to that of PSI’s x-ray laser SwissFEL, the researchers were able to demonstrate that the experiments planned for SwissFEL are possible and they are now building an experimental station at SwissFEL.

Batman lights the way to compact data storage

Media Releases Matter and Material Research Using Synchrotron Light Materials Research

Researchers at the Paul Scherrer Institute (PSI) have succeeded in switching tiny, magnetic structures using laser light and tracking the change over time. In the process, a nanometre-sized area bizarrely reminiscent of the Batman logo appeared. The research results could render data storage on hard drives faster, more compact and more efficient.

Shortcut to protein portraits

Media Releases Research Using Synchrotron Light Biology

All living organisms, from bacteria to humans, rely on proteins to perform their vital functions. How these proteins accomplish their tasks depends on their structure. Researchers from the Paul Scherrer Institute have now devised a novel method to determine the crystal structure of proteins using X-ray light, which could also hasten the development of new drugs in future. The study will be published in the journal Nature Methods on 15 December.
