Forschung für die Halbleiterelektronik
Forschende des PSI haben zusammen mit Forschenden der der Universität Cornell im US-Bundesstaat New York haben ein Verbundmaterial identifiziert, das Quantenbauelemente in die Halbleitertechnologie integrieren und damit elektronische Bauteile deutlich leistungsstärker machen könnte. Zu den derzeit wichtigsten Herausforderungen in der Halbleiterelektronik gehören Verbesserungen, die die Bandbreite der Datenübertragung, die Energieeffizienz und die Informationssicherheit erhöhen würden. Die Einbeziehung von Quanteneffekten könnte für einen neuen Durchbruch sorgen und richtungsweisend für die Halbleiterindustrie sein.
Confirming the trilinear form of the optical magnetoelectric effect in the polar honeycomb antiferromagnet Co2Mo3O8
Magnetoelectric phenomena are intimately linked to relativistic effects and also require the material to break spatial inversion symmetry and time-reversal invariance. Magnetoelectric coupling can substantially affect light–matter interaction and lead to non-reciprocal light propagation. Here, we confirm on a fully experimental basis, without invoking either symmetry-based or material-specific assumptions, that the optical magnetoelectric effect in materials with non-parallel magnetization (M) and electric polarization (P) generates a trilinear term in the refractive index...

Marie-Christine Zdora joins the X-ray Tomography Group
The X-ray Tomography group welcomes Marie-Christine Zdora as a new member. In her role as translational X-ray imaging adjunct scientist, Marie will mainly work on phase-contrast and dark-field imaging focusing on the further development of these techniques towards their clinical translation. Before joining TOMCAT, Marie was a postdoc in the X-ray optics and applications group at the Laboratory for Micro- and Nanotechnology (LMN) at PSI, where she worked on the development of new X-ray optics as well as X-ray wavefront sensing. Prior to this position, she was a research fellow at the University of Southampton in the UK, where she made advances in X-ray speckle-based imaging using synchrotron and lab sources.

Effektiv kombinierte Tumortherapie
Forschende des Paul Scherrer Instituts PSI haben verschiedene Verfahren zur Bekämpfung bestimmter Krebsarten auf ihre Effektivität überprüft. Die Kombination aus zwei Präparaten zeigte dabei eine deutlich bessere Wirkung als die Behandlung mit nur einem der beiden Wirkstoffe. Vor allem für die Behandulng von modulären Schilddrüsenkarzinome ist dies von Bedeutung. Wenn sich die bisherigen Ergebnisse in zukünftigen Studien bestätigen, könnte diese Therapie in einigen Jahren der Allgemeinheit zur Verfügung stehen.

Deep learning based classification of dynamic processes in time-resolved X-ray tomographic microscopy
Time-resolved X-ray tomographic microscopy provides new opportunities in the volumetric investigation of dynamic processes. Full exploitation of these new capabilities is currently still hindered by the lack of efficient post-processing approaches capable of handling TBs of noisy datasets. A deep learning based reconstruction and classification algorithm designed to reconstruct and segment dynamic processes within a static matrix with high efficiency is a solution to this issue. In a paper published recently in Scientific Reports, we demonstrate the advantages of the proposed approach on dynamic, time-resolved fuel cell data, for which the current data post-processing pipeline heavily relies on manual labor, typically limiting the experimental plans to just a small range of the full parameter space.
Priority access call for work on combating COVID-19 continues
On January 30th, 2020, the WHO declared the recent outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of international concern. It declared that there is an urgent need to improve our understanding of the newly identified virus and its possible future evolution as well as to contain the spread; to develop precise diagnostics and treatment, and to improve the public health response and patient care.
The COVID priority access call continues and is still open in 2022.
Signatures of Weyl Fermion Annihilation in a Correlated Kagome Magnet
The manipulation of topological states in quantum matter is an essential pursuit of fundamental physics and next-generation quantum technology. Here we report the magnetic manipulation of Weyl fermions in the kagome spin-orbit semimetal Co3Sn2S2, observed by high-resolution photoemission spectroscopy. We demonstrate the exchange collapse of spin-orbit-gapped ferromagnetic Weyl loops into paramagnetic Dirac loops under suppression of the magnetic order.

Reactivity and potential profile across the electrified LiCoO2-Li3PS4 interface probed by operando X-ray photoelectron spectroscopy
All-solid-state lithium batteries are a promising alternative for next generation of safe energy storage devices, provided that parasitic side reactions and the resulting hindrances in ionic transport at the electrolyte-electrode interface can be overcome. Motivated by the need for a fundamental understanding of such interface, we present here real-time measurements of the (electro-)chemical reactivity and local surface potential at the electrified interface Li3PS4 and LiCoO2 using operando X-ray photoelectron spectroscopy.
