Abandon de l’énergie nucléaire, développement de l’énergie solaire et éolienne, production d’énergie à partir de la biomasse, réduction de la consommation d’énergie. D’ici 2050, la Suisse doit atteindre la neutralité climatique. Un objectif ambitieux, rendu plus urgent que jamais par une situation géopolitique de plus en plus difficile. Comment faire pour mettre en place ces prochaines années un approvisionnement énergétique durable et résistant pour la Suisse? Comment les énergies renouvelables peuvent-elles être utilisées de manière optimale? Quelles sont les nouvelles technologies les plus prometteuses? Au PSI, des chercheurs s’efforcent de trouver des réponses à ces questions décisives.

PRISMAP Radiolanthanides Workshop: Advancing Cancer Therapy
The PRISMAP Radiolanthanides Workshop took place at the Paul Scherrer Institute in Switzerland from September 3 to 5, 2024. This influential three-day event gathered leading experts to review the latest advancements in radiolanthanides—radioactive elements at the forefront of cancer therapy. The workshop showcased cutting-edge developments in radiolanthanide production and explored their applications in both preclinical and clinical settings. A key highlight was an insightful panel discussion on the "Clinical Translation of Terbium-161 and Lessons Learned," which provided valuable takeaways for the future of cancer treatment. The event received extensive media coverage and was recently featured by the Swiss Society of Radiopharmacy and Radiopharmaceutical Chemistry (SGRRC)

Wir teilen eine Zusammenfassung hier auf dem Career Blog, um Arbeitgebende dabei zu unterstützen, unsere Talente mit den Argumenten abzuholen, die relevant für sie sind.
SCS Fall Meeting 2024 and Paul
On September 5, 2024, the Fall Meeting 2024 of the Swiss Chemical Society took place. The annual event attracts young (and old) chemists from all over Switzerland and gathers them at one of the country’s major universities. This year’s edition was held at the University of Fribourg. While most PhD students of LRC participated with poster presentations, Jennifer Wilson and Michael Hofstetter managed to secure themselves one of the rare spots for an oral presentation. Among many outstanding contributions, Paul Dutheil won the Best Poster Award - congratulations from the whole LRC to our honorary member, Paul! Well done :)

NRC 10 and Mike
During the week of August 25-30, 2024, members of the Laboratory of Radiochemistry attended the International Conference on Nuclear and Radiochemistry NRC10 in Brighton, United Kingdom. The conference covered a wide range of topics in the field and, although generally having a European focus, attracted international experts from around the world. Members of LRC gave strong poster presentations and great talks. Finally, Michael Hofstetter won the prize for the best oral presentation with his talk entitled “Unravelling ultra-trace lanthanide impurities in nuclear forensics evidence” – congratulations from all of us, Mike! Well deserved :)
Highlights from the 1st CSD Scientific Retreat
The 1st Scientific Computing, Theory and Data Scientific Retreat commenced on March 13th, 2024, marking a significant milestone in the collaborative efforts of the division researchers and scientists. Hosted at the Dorfschüür Würenlingen, the event brought together the division to share insights, updates, and visions for the future of our division.
Uncovering the secrets of rapid and green metal-organic framework synthesis
Using ATR-IR spectroscopy and high-energy XRD, we have studied the mechanism of ambient temperature aqueous synthesis of Zn-MOF-74. Starting from the need to change Zn precursor to disentangle signals in ATR-IR spectroscopy, we also developed a rapid synthesis of Zn-MOF-74 with Zn perchlorate.
Carbenium ions in the methanol-to-olefins process
The methanol-to-olefins process converts methanol into hydrocarbons over zeolite-based catalysts following a dual-cycle reaction mechanism within the paradigm of an hydrocarbon pool chemistry. In this work, we use operando DRIFTS/GC to correlate the nature of species residing within the porosity of zeolites (DRIFTS) and the products distribution (GC).
Quantum Spin Dynamics Due to Strong Kitaev Interactions in the Triangular-Lattice Antiferromagnet CsCeSe2
The extraordinary properties of the Kitaev model have motivated an intense search for new physics in materials that combine geometrical and bond frustration. In this Letter, we employ inelastic neutron scattering, spin wave theory, and exact diagonalization to study the spin dynamics in the perfect triangular-lattice antiferromagnet (TLAF) CsCeSe2. This material orders into a stripe phase, which is demonstrated to arise as a consequence of the off-diagonal bond-dependent terms in the spin Hamiltonian ...

Evidence for time-reversal symmetry-breaking kagome superconductivity
Superconductivity and magnetism are often antagonistic in quantum matter, although their intertwining has long been considered in frustrated-lattice systems. Here we utilize scanning tunnelling microscopy and muon spin resonance to demonstrate time-reversal symmetry-breaking superconductivity in kagome metal Cs(V, Ta)3Sb5, where the Cooper pairing exhibits magnetism and is modulated by it. In the magnetic channel, we observe spontaneous internal magnetism ...
Hydrogen Electrode for Membrane Water Electrolyzers with Low Gas Crossover
Proton exchange membrane (PEM) water electrolyzer are considered a for the Energy Transition to produce green hydrogen for fuel cell-based mobility, industrial processes, and seasonal storage. Platinum group metals (PGMs) are conventionally used as catalysts for electrode reactions due to their outstanding catalytic activity and chemical stability in the harsh acidic environment of the cell. Commercial carbon-supported platinum (Pt/C) electrocatalysts remains a state-of-the-art choice for the hydrogen evolution reaction (HER) on the cathode side of the cell. While a high Pt loading between 0.5 and 1.0 mgPt/cm2 is commonly used today, a reduction of the Pt loading to below 0.05 mgPt/cm2 is desired to reduce the cost of PGM usage in megawatt-scale PEM water electrolysis systems. In addition, in connection with the trend towards the use of thinner membranes (<0.1 mm), gas crossover through the membrane from the cathode to the anode side can lead to the formation of an explosive gas mixture in the anode product stream. In this study, we varied the design parameters for the cathode catalyst layer to reduce the Pt loading to 0.025 mg/cm2 while at the same time minimizing the rate of hydrogen crossover to the anode.
Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution
Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density.

Controlling magnetic waves in a spin liquid
Scientists at the Paul Scherrer Institute PSI have shown that excitation of a spin liquid with intense THz pulses causes spins to appear and align within less than a picosecond. This induced coherent state causes a magnetic field to form inside the material, which is detected using ultrashort X-ray pulses at the X-ray Free Electron Laser SwissFEL.

Novel Photoresist Chemistry Enables Lithography Approaching Angstrom-Scale Resolution
Photoresist materials are crucial in the manufacturing of computer chips, where the circuits are initially printed in the photoresist using photolithography. As the demand for smaller and more precise circuitry in computer chips grows, photoresists must resolve features with smaller sizes and higher density. One of the factors determining the ultimate resolution in lithography is the molecular size/mass of the photoresists.
