The manifold characteristics of materials are determined by what type of atoms they are made of, how these atoms are arranged, and how they move. In the research area Future Technologies, scientists at the Paul Scherrer Institute are trying to clarify this link between the internal structure and the observable properties of different materials. They want to use this knowledge as fundamental principles for new applications – whether in medicine, information technology or energy generation and storage – or to explore innovative manufacturing processes for industry.

PSI researchers have developed a material whose shape memory is activated through magnetism. Application areas for this new kind of composite material include, for example, medicine, space flight, electronics, and robotics.
Researchers at PSI have investigated a novel crystalline material at the Swiss Light Source SLS that exhibits electronic properties never seen before. Among other things, they were able to detect a new type of quasiparticle: so-called Rarita-Schwinger fermions.
Researchers at PSI have discovered a new phenomenon of magnetism with the help of the Swiss Light Source SLS. Certain groups of atoms behave like a compass pointing West. This could make computers much more powerful.
Electronics should get smaller, faster, and above all more energy-efficient. These themes are also present in several research groups at PSI. From incremental improvements to complete rethinking – who is currently working on what?
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.
If you make electronic components smaller, they unfortunately get hotter. Also, we will soon reach the limit of technically feasible miniaturisation. At PSI, Gabriel Aeppli and Christian Rüegg are working on fundamentally new, physical solutions for better computers and data storage devices.
A PSI-developed detector called POLAR has collected data on so-called gamma-ray bursts from a space station. This is now helping to better understand these extremely high-energy flashes of light.
A team with three researchers from the ETH Domain has been awarded a prestigious EU grant. Today, they received the contract signed by the EU confirming the extraordinary 14 million euros funding. With it, they will investigate quantum effects which could become the backbone of future electronics.
Use of multiferroic materials promises more energy-efficient computers because in these, an electric field would suffice to achieve magnetic data storage. Researchers at PSI have now made such a material suitable for computer operating temperatures.
The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain unknown. Now, for the first time, researchers at the Paul Scherrer Institute PSI have observed electrons while they were flowing in this promising transistor. For that they used one of the world's best sources of soft X-rays at PSI's Swiss Light Source SLS.
The 16th of May is the International Day of Light. The research carried out with light at PSI enables advances in biology and pharmacology and also promotes the development of new materials for data storage and new technologies for personalised medicine.
Nowhere in the world have so many ocular tumours been irradiated with protons as at PSI. But before the affected patients go to Villigen, they have to visit Lausanne: for pretreatment at the Jules Gonin Ophthalmic Hospital. The more than 30-year-long collaboration between the hospital and PSI is unique, and in most cases it saves the patient's diseased eye.
The ABB facility in Wettingen got practical recommendations on increasing production of ceramic components. Researchers at the Paul Scherrer Institute PSI examined the components by means of neutron imaging. With the help of these images, ABB employees were able to see where there is still potential for process optimisation. This feasibility study was funded by the Hightech Zentrum Aargau.
Oles Sendetskyi, winner of a Founder Fellowship at the Paul Scherrer Institute PSI, wants to use polarity reversal in nanomagnets to develop a sustainable power source for small devices.
No evidence of dark matter made of axions – result of an experiment at the Paul Scherrer Institute PSI further constrains theories about the nature of dark matter.
Ancient metal objects are illuminated by neutrons at the Paul Scherrer Institute PSI. This enables researchers to discover what is hidden inside them, how they were made and how they can be preserved.
Federica Marone illuminates objects with high-intensity X-ray beams, Eberhard Lehmann with neutrons. Both have used their methods to give palaeontologists and archaeologists a new view into the past.
For the first time, scientists have made visible the directions of the magnetisation inside a 3D magnetic object. The smallest details in their visualisation were ten thousand times smaller than a millimetre. Among others, the magnetic structure contained one outstanding kind of pattern: magnetic singularities called Bloch points, which up to now were only known in theory.
An X-ray free-electron laser (XFEL) is capable of visualizing extremely fast structural and electronic processes. Pilot experiments will take place at the PSI's Swiss Free-Electron Laser (SwissFEL) from the end of 2017 on. Two current publications in Science and Nature Communications demonstrate the kind of outstanding scientific work that is enabled by such facilities. The work was carried out at the Linac Coherent Light Source (LCLS) in California. Two of the leading authors behind these studies have now relocated to the PSI in order to share their expertise as SwissFEL expands its capabilities.
Lignin, as a constituent of many plants, accumulates in large quantities and could theoretically be used as a precursor material for production of fuels and chemicals. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a method with which the processes that take place in the catalytic breakdown of lignin can be observed in detail. The knowledge thus gained could enable targeted improvement of production methods in the future.
