At PSI, several projects are dedicated to important research questions concerning the Sars-CoV-2 coronavirus and the resulting diseases. We provide information on activities and projects, for example on investigations of lung tissue, on the production of proteins and antibodies or on ideas for new research on Covid-19.

Success through collaboration: PSI and SwissNeutronics AG
Technology transfer - meaning the transfer of research results to industry - can take place in various ways. Founding a spin-off is a very efficient way of transferring or commercialising a technology developed at PSI to industry. In recent years, PSI has founded a number of such spin-offs from various research areas. Even years later, PSI is still in close contact with most of its spin-offs, from which both sides can benefit. The company "SwissNeutronics AG", based in Klingnau, is the oldest PSI spin-off and was spun off as early as 1999. For more than 20 years, SwissNeutronics and the PSI have repeatedly worked together successfully on various projects and can mutually benefit from synergy effects.

Congratulation Noemi and Mario !
PSI: Doktorandentag des Departements Nukleare Energie und Sicherheit 2022.
The Department of Nuclear Energy and Safety (NES) of the Paul Scherrer Institut (PSI) held its annual PhD Day. The PhD students presented their research work to a jury, which awarded the best presentations in each of the various categories with a prize donated by the Nuklearforum Schweiz.
This year Noemi Cerboni and Mario Veicht, first and fourth year PhD students, respectively, of LRC won this prestigious award.

KV-Praktikumsbericht

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.
Self-analysis - fascinating instrument or tool by the devil?
While we ask ourselves every now and then whether we are still happy in our private lives, we often hesitate to do the same in our professional lives. Why this should be necessary?
Taking the time to assess your own professional situation is very valuable. Especially because nowadays a career is almost never straightforward, it is often helpful to be aware of certain points.

Things run smoother without lubricants
At the particle accelerators of PSI, the components have to withstand harsh conditions. This is why a special ball bearing that does not require grease as a lubricant has been in use since last year.
In situ Study of Low-temperature Dry Reforming of Methane Over La2Ce2O7 and LaNiO3 Mixed Oxides
The combination of in situ spectroscopy methods allowed to detect the evolution of a catalyst precursor to the catalytic material, and investigate a relevant reaction. The reduction of a mixture of perovskite, pyrochlore and nickel leads to the formation of active and selective catalytst, converting carbon dioxide and methane to syngas.

Low-temperature magnetic crossover in the topological kagome magnet TbMn6Sn6
Magnetic topological phases of quantum matter are an emerging frontier in physics and materials science, of which kagome magnets appear as a highly promising platform. Here, we explore magnetic correlations in the recently identified topological kagome system TbMn6Sn6 using muon spin rotation, combined with local field analysis and neutron diffraction. Our studies identify an out-of-plane ferrimagnetic structure with slow magnetic fluctuations which exhibit a critical slowing down below T*C1 ≃ 120 K and finally freeze into static patches with ideal out-of-plane order below TC1 ≃ 20 K....

In situ spectroscopy unveils the structural changes of the sites in single atom catalysts
To improve the performance of single atom catalysts (SACs), the structure of their active sites under operative conditions needs to be better understood. For this, we have performed in situ X-ray absorption spectroscopy measurements using a modulation excitation approach selectively sensitive to the species involved in the electrochemical reactions. This has allowed us to study the structural changes undergone by two types of SACs, and to tie the observed differences to their catalytic activities.
