SwissFEL

La plus récente grande installation de recherche du PSI génère de très courtes impulsions de rayons X, ayant les propriétés du laser. Cela permet aux chercheurs de suivre des processus extrêmement rapides tels que l'apparition de nouvelles molécules lors de réactions chimiques, de déterminer la structure détaillée de protéines vitales ou de comprendre la composition exacte de matériaux. Les chercheurs pourront ainsi obtenir des informations auxquelles les méthodes actuelles ne permettent pas d'accéder. Les connaissances acquises élargissent notre compréhension de la nature et débouchent sur des applications pratiques telles que de nouveaux médicaments, des processus plus efficaces dans l'industrie chimique ou de nouveaux matériaux en électronique.

Jisoo Kim bags the 2022 Werner Meyer-Ilse Award

Jisoo Kim was awarded the 2022 Werner Meyer-Ilse Memorial Award. The WMI Award is given to young scientists for exceptional contributions to the advancement of X-ray microscopy through either outstanding technical developments or applications, as evidenced by their presentation at the International Conference on X-ray Microscopy and supporting publications.  Jisoo was awarded for his development of the method "Time-resolved x-ray scattering tomography for rheological studies", and is co-recipient of the award with Yanqi Luo from the Advanced Photons Source for her work on applications. The award was presented during the 15th International Conference on X-ray Microscopy XRM2022 hosted by the National Synchrotron Radiation Research Center (NSRRC) in Hsinchu, Taiwan on 19 - 24 June, 2022.

Synthesis of Metallic Lanthanide Thin Samples

This work aimed to produce intermetallic samples of platinoid metals (active metal matrix) and lanthanides (co-metal) and via the method of Coupled Reduction, i.e. a thermal treatment of the combination of the lanthanide oxide and noble metal at high temperature, as high as 1100 °C, under a constant flow of H2. We have demonstrated by means of several techniques, such as Scanning Electron Microscope, Energy Dispersive X-Ray Spectroscopy, Alpha Spectrometry and Radiographic Imaging, that this method, at defined experimental conditions (temperature, pressure and concentration) yields a metallic lanthanide thin film when using platinum as active metal matrix. Conversely, the formation of a bulk intermetallic compound was obtained when using Pd as matrix. Those systems will have applications in different nuclear physic and radiochemistry studies, such as irradiation targets for production of superheavy elements and for nuclear data determination.

SANS-LLB at PSI: keeping up with the soft matter community needs

The shutdown of the Orphée reactor at LLB (Saclay, France) and the upgrade of the SINQ neutron guide system at PSI (Villigen, Switzerland) in 2019 were the beginning of a long-term collaboration between PSI and LLB. The SANS-LLB instrument, formerly known as PA20, has travelled more than 500 km, and since 2020 is being installed at SINQ/PSI as a collaborative effort between PSI and LLB. The aim is to make a modern SANS instrument available to the soft matter neutron scattering community at the SINQ spallation source.

Stable Performance of High Capacity Cobalt-Free Li-ion Battery

Lithium-rich layered oxides, containing cobalt, despite being promising high-capacity cathode materials, need alternatives to eliminate toxic and geopolitically restricted cobalt. An ongoing search for low-cost, Co-free Li-rich cathode materials with a better structural stability lead to investigation of Li1.16Ni0.19Fe0.18Mn0.46O2 (LNFM), where cobalt is replaced by abundant iron. Our LNFM not only delivered a high capacity of 229 mAh/g but also has a stable average discharge voltage when cycled to upper cutoff potential of 4.8 V in additive-free electrolyte.

Erfolg durch Zusammenarbeit: PSI und SwissNeutronics AG

Technologietransfer – also der Transfer von Forschungsresultaten in die Industrie - kann über verschiedene Wege erfolgen. Die Gründung eines Spin-offs ist ein sehr effizienter Weg, um eine Technologie, die am PSI entwickelt wurde, in die Industrie zu transferieren bzw. zu kommerzialisieren. Seitens PSI wurden in den letzten Jahren aus verschiedenen Forschungsbereichen einige solcher Spin-offs ausgegründet – mit manchen Spin-offs steht das PSI auch nach Jahren noch in engem Austausch, von welchem beide Seiten profitieren können. Die Firma «SwissNeutronics AG» mit Sitz in Klingnau ist das älteste Spin-off des PSI und wurde bereits 1999 ausgegründet. Seit über 20 Jahren arbeiten SwissNeutronics und das PSI immer wieder an verschiedenen Projekten erfolgreich zusammen und können gegenseitig Synergieeffekte nutzen.

Light-Induced Magnetization at the Nanoscale

Targeted manipulations of an atom's magnetic moment are tricky, as the charge currents used for this process are extremely difficult to control . Now, a consortium of collaborators in Germany, Switzerland, Slovenia and Italy reports on a solution to this problem in the cover page article of Physic Review Letters 128, Vol. 15. As it appears, the magnetization of an atomic gas can be altered by high-power lasers using a patterned wave front. The method is promising for studying and manipulating the magnetic properties of matter at the nanoscale.

Unveiling Unequivocal Charge Stripe Order in a Prototypical Cuprate Superconductor

In the cuprates, high-temperature superconductivity, spin-density-wave order, and charge-density-wave (CDW) order are intertwined, and symmetry determination is challenging due to domain formation. We investigated the CDW in the prototypical cuprate La1.88Sr0.12CuO4 via x-ray diffraction employing uniaxial pressure as a domain-selective stimulus to establish the unidirectional nature of the CDW unambiguously.

LNQ Kick-off

On April 11th, we had the opportunity to celebrate the kick-off meeting of the new Laboratory of Nano and Quantum Technologies (LNQ), and many had the chance to meet their new colleagues for the first time. Presently, our lab joins together two cleanroom-technology focused groups, Nanotechnology led by Dr. Vitaliy Guzenko and Advanced Nanomanufacturing by Dr. Helmut Schift, respectively, with groups focusing on three different technology platforms in quantum computing. These are Ion trap Quantum Computing led by Dr. Cornelius Hempel, Superconducting Quantum Circuits that is an extension of Prof. Andreas Wallraff's activities at ETHZ, and Neutral Atoms Quantum Engineering, which will be led by Prof. Wenchao Xu joining in August.

Selbstanalyse - faszinierendes Werkzeug oder Werkzeug des Teufels?

Self-Assessment

Während wir uns immer mal wieder fragen, ob wir in unserem Privatleben noch glücklich sind, zögern wir oft, das Gleiche in unserem Berufsleben zu tun. Weshalb das notwendig sein sollte?

Sich die Zeit zu nehmen um die eigene beruflichen Situation einzuschätzen, ist sehr wertvoll. Gerade, weil heutzutage eine Karriere fast nie geradlinig verläuft, ist es oftmals hilfreich sich bestimmte Punkte bewusst zu machen.
