Future Technologies

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.

Structure of concrete disease solved

Media Releases Research Using Synchrotron Light Future Technologies

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.

Put in perspective

Media Releases Large Research Facilities Future Technologies Materials Research SwissFEL

Researchers from the Paul Scherrer Institute PSI have succeeded in using commercially available camera technology to visualise terahertz light. In doing so, they are enabling a low-cost alternative to the procedure available to date, whilst simultaneously increasing the comparative image resolution by a factor of 25. The special properties of terahertz light make it potentially advantageous for many applications. At PSI, it will be used for the experiments on the X-ray free-electron laser SwissFEL.

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.

Magnets made of non-magnetic metals

Media Releases Future Technologies Materials Research Research with muons

For the first time, an international research team has demonstrated how to generate magnetism in metals that aren’t naturally magnetic, such as copper. The discovery could help develop novel magnets for a wide range of technical applications. Crucial measurements to understand this phenomenon were carried out at PSI à the only place where magnetic processes inside materials can be studied in sufficient detail.

Puzzling new behaviour observed in high-temperature superconductors

Media Releases Future Technologies Materials Research Research Using Synchrotron Light

New effect might be important for emergence of High-Temperature SuperconductivityAn international team of researchers has observed a new, unexpected kind of behaviour in copper-based high-temperature superconductors. Explaining the new phenomenon à an unexpected form of collective movement of the electrical charges in the material à poses a major challenge for the researchers. A success in explaining the phenomenon might be an important step toward understanding high-temperature superconductivity in general. The crucial experiments were conducted at the Paul Scherrer Institute.

Useful for spintronics: Big surprises in a thin surface region

Media Releases Research Using Synchrotron Light Materials Research Future Technologies

The need for ever faster and more efficient electronic devices is growing rapidly, and thus the demand for new materials with new properties. Oxides, especially ones based on strontium titanate (SrTiO3), play an important role here. A collaborative project headed by scientists from the PSI has now revealed properties of strontium titanate that make it an important base material for applications in spintronics.

Insulator makes electrons move in an ordered way

Media Releases Research Using Synchrotron Light Materials Research Future Technologies

Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator à a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

Astral matter from the Paul Scherrer Institute

Media Releases Future Technologies

Processes in stars recreated with isotopes from PSIIsotopes that otherwise only naturally exist in exploding stars à supernovae à are formed at the Paul Scherrer Institute’s research facilities. This enables processes that take place inside the stars to be recreated in the lab. For instance, an international team of researchers used the titanium isotope Ti-44 to study one such process at CERN in Geneva. In doing so, it became evident that it is less effective than was previously believed and the previous theoretical calculations of processes in stars need to be corrected.

Superconductivity switched on by magnetic field

Media Releases Research Using Neutrons Materials Research Future Technologies

Superconductivity and magnetic fields are normally seen as rivals à very strong magnetic fields normally destroy the superconducting state. Physicists at the Paul Scherrer Institute have now demonstrated that a novel superconducting state is only created in the material CeCoIn5 when there are strong external magnetic fields. This state can then be manipulated by modifying the field direction. The material is already superconducting in weaker fields, too. In strong fields, however, an additional second superconducting state is created which means that there are two different superconducting states at the same time in the same material.

Electrons with a "split personality"

Media Releases Research Using Synchrotron Light Materials Research Future Technologies

Above the transition temperature, some electrons in the superconducting material La1.77Sr0.23CuO4 behave as if they were in a conventional metal, others as in an unconventional one à depending on the direction of their motion. This is the result of experiments performed at the SLS. The discovery of this anisotropy makes an important contribution towards understanding high-temperature superconductors. The effect will also have to be taken into account in future experiments and theories of high-temperature superconductors.

Towards sodium ion batteries – understanding sodium dynamics on a microscopic level

Research Using Neutrons Future Technologies Storage

Understanding sodium dynamics on a microscopic levelLithium ion batteries are highly efficient, But there are drawbacks to the use of lithium: it is expensive and its extraction rather harmful to the environment. One possible alternative might be to substitute lithium with sodium. To be able to develop sodium-based batteries, it is crucial to understand how sodium ions move in the relevant materials. Now, for the first time, scientists at the Paul Scherrer Institute PSI have determined the paths along which sodium ions move in a prospective battery material. With these results, one can now start to think of new and specific ways to manipulate the materials through slight changes to their structure or composition, for example à and thereby achieve the optimized material properties necessary for use in future batteries.
