Quantum melting

Media Releases Research Using Neutrons Large Research Facilities

Changes to the aggregate state triggered by quantum effects à in physically correct terms, quantum phase transitions à play a role in many astonishing phenomena in solids, such as high-temperature superconductivity. Researchers from Switzerland, Great Britain, France and China have now specifically altered the magnetic structure of the material TlCuCl3 by exposing it to external pressure and varying this pressure. With the aid of neutrons, they were able to observe what happens during a quantum phase transition, where the magnetic structure melts quantum-physically.

Superconductivity switched on by magnetic field

Media Releases Research Using Neutrons Materials Research Matter and Material

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.

The Paul Scherrer Institute runs two of the energy competence centres of the Swiss government

Energy and Environment Media Releases

As part of the Energy Strategy 2050 the Swiss government and parliament have decided to increase support for energy research in Switzerland. This includes the setting up of seven interuniversity networked Swiss Competence Centres in Energy Research (SCCERs). In the SCCERs ETH Domain institutions, the universities and the universities of the applied sciences are to join forces with industrial partners to develop new competencies and solutions in the decisive action areas of the shift in energy policy. The Paul Scherrer Institute PSI will act as the leading house in two of the SCCERs à storage and biomass à that have already been given the green light. They will begin their work in 2014.

How botox binds to neurons

Media Releases Biology Research Using Synchrotron Light Human Health

Botox is a highly dangerous toxin that causes paralysis. In cosmetic applications it is used to temporarily eliminate wrinkles and in medicine as a treatment for migraine or to correct strabismus. An international research team has now established how the toxin molecule binds to the neuron whose activity is then blocked by the poison. The findings may be useful for the development of improved drugs with a lower risk of overdosage.

Electrons with a "split personality"

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

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.

A promising new method for the diagnosis of breast cancer

Media Releases Medical Science Human Health

A new mammography procedure that could generate substantial added value for the diagnosis of breast cancer in medical practice has just been published in the scientific journal “Investigative Radiology”. The method was developed at PSI in cooperation with the Certified Breast Centre at the Kantonsspital (cantonal hospital in) Baden and Philips as an industrial partner and is making the tiniest tissue changes visible. This has the potential to improve the early detection of breast cancer. Further studies in women suffering from breast cancer are to prove in a definitive manner the added value of the method.

Zähnen

Media Releases Research Using Synchrotron Light User experiments Biology

Mit Hilfe von Röntgenlicht aus der Synchrotron Lichtquelle Schweiz des PSI ist es Paläontologen der Universität Bristol gelungen, ein Rätsel um den Ursprung der ersten Wirbeltiere mit harten Körperteilen zu lösen. Sie haben gezeigt, dass die „Zähne“ altertümlicher Fische (der sogenannten Conodonten) unabhängig von den Zähnen und Kiefern heutiger Wirbeltiere entstanden sind. Die Zähne dieser Wirbeltiere haben sich vielmehr aus einem Panzer entwickelt, der dem Schutz vor den Conodonten, den ersten „Raubtieren“, diente.

Magnetisation controlled at picosecond intervals

Media Releases Matter and Material Materials Research Large Research Facilities SwissFEL

A terahertz laser developed at the Paul Scherrer Institute makes it possible to control a material’s magnetisation precisely at a timescale of picoseconds. In their experiment, the researchers shone extremely short light pulses from the laser onto a magnetic material. The light pulse’s magnetic field was able to deflect the magnetic moments from their idle state in such a way that they exactly followed the change of the laser’s magnetic field with only a minor delay. The terahertz laser used in the experiment is one of the strongest of its kind in the world.

Five times less platinum: fuel cells could become economically more attractive thanks to novel aerogel catalyst.

Media Releases Energy and Environment

Fuel cells that convert hydrogen into power and only produce pure water as a by-product have the potential to lead individual mobility into an environmentally friendly future. The Paul Scherrer Institute (PSI) has been researching and developing such low-temperature polymer electrolyte fuel cells for more than 10 years and initial field tests have already demonstrated the successful use of these fuel cells in cars and buses. However, further research is still required to improve the durability and economic viability of the technology. An international team of researchers involving the PSI has now manufactured and characterised a novel nanomaterial that could vastly increase the efficiency and shelf-life of these fuel cells à as well as reduce material costs.

Ferromagnetic and antiferromagnetic – at the same time

Media Releases Matter and Material Materials Research

Researchers from the Paul Scherrer Institute (PSI) have made thin, crystalline layers of the material LuMnO3 that are both ferromagnetic and antiferromagnetic at the same time. The LuMnO3 layer is ferromagnetic close to the interface with the carrier crystal. As the distance increases, however, it assumes the material’s normal antiferromagnetic order while the ferromagnetism steadily becomes weaker. The possibility of producing two different magnetic orders within a material could be of major technical importance.
