Unpaired Weyl Point observed for the first time in crystalline solid
Flows need sources and sinks. That’s why, in a new class of exotic materials called Weyl semimetals, the sources and sinks of Berry curvature – dubbed Weyl points – were believed to exist only in pairs. Now researchers at PSI have observed unpaired Weyl points for the first time in a crystalline solid. This discovery, which upends conventional thinking and the so-called Nielson-Niomiya no-go theorem, demonstrates the unique properties of "nodal wall" Weyl semimetals in comparison to conventional Weyl systems having only zero-dimensional Weyl nodes.

Hierarchical imaging and computational analysis of three-dimensional vascular network architecture in mouse brain
An international team involving researchers from the University and University Hospital Zürich, the Krembil Research Institute and the University and University Hospital in Toronto (Canada), the Department of Physics of Jyväskylä (Finland), the University of Leuven (Belgium), the Johannes Kepler University in Linz (Austria), the Novartis Institutes for Biomedical Research in Emeryville (USA), the ETH Zürich and the Paul Scherrer Institute has developed a protocol that enables hierarchical imaging and computational analysis of vascular networks in entire postnatal- and adult mouse brains, enabling direct and quantitative comparisons of the morphological brain vascular network architecture between different postnatal and / or adult developmental stages. The results have been published on Nature Protocols on September 3rd, 2021.
Watch them growing: New mechanistic insights into catalytic methane coupling
Methane valorization is a promising technology to utilize this platform compound to produce aromatics and hydrocarbons. Researchers from PSI and ETH Zürich unveiled this reaction mechanism and observed the molecular growth from the ground up. Besides stepwise CH3 addition, novel routes involving the dimerization of resonantly stabilized propargyl (C3H3) radicals to benzene (C6H6) were identified. These mechanistic insights will aid the development of valorisation strategies.

First direct observation of the oxygen transport in polymer electrolyte water electrolysis
PSI researchers have developed a new methodology for studying the complex transport processes in polymer electrolyte water electrolysis (PEWE). Using advanced operando X-ray tomographic microscopy, we were able to observe for the first time the formation of oxygen pathways in the porous transport layer, in three dimensions. Understanding oxygen transport is crucial for improving PEWE technology and this work provides precious insights for the design of future, better-performing PEWE cells.

Nanobodies against SARS-CoV-2
In a study published in EMBO Journal, researchers at the Max Planck Institute for Biophysical Chemistry, Göttingen, Germany, developed nanobodies that efficiently block the coronavirus SARS-CoV-2 and its variants. The high resolution structural characterization was performed at the X10SA crystallography beamline at the Swiss Light Source.
Creating novel quantum phases via the heterostructure engineering
Within this synergetic collaboration, PSI scientists have investigated the correlation between magnetic and electronic ordering in NdNiO3 by tuning its properties through proximity to a ferromagnetic manganite layer. The main outcome is that the stray magnetic field from the manganite layer causes a novel ferromagnetic-metallic (FM-M) phase in NNO. This work demonstrates the utilization of heterostructure engineering for creating novel quantum phases.
The MagnoCell Team
Performing PhD research is generally focused on answering key questions in basic sciences. However, sometimes, these projects find real-world applications. To do so, out-of-the- box thinking and innovation are crucial. To put these to the test, the Swiss Nanoscience Institute (SNI) of the University of Basel organized a workshop called: “Innovation Workshop: From Lab to Start-up” for SNI PhD students. During this workshop, the PhD students had the opportunity to develop ideas for a possible future start-up and present them in a short, but powerful pitch to convince potential investors. The three SNI students from the team Magnocell, including three from the Paul Scherrer Institute took part and were awarded first prize. The winning team was consisted out of: Thomas Mortelmans of the Laboratory of Micro-and Nanotechnology, Shichao Jia of the Laboratory of Nanoscale Biology and Antonia Ruffo of the Electrochemistry Laboratory and Tamara Aderneuer of CSEM Basel. Their idea was to create a company that has the potential to revolutionize modern fuel cells and could make an impact on a billion dollar landscape.
When Shichao was asked about his opinion concerning the workshop, he said the following:
‘In general, dissemination of the advances in basic sciences to the public is never easy. It is even more so in a business context where you would probably have to sell your scientific idea to potential investors. In my opinion, this workshop was deliberately organized to train and prepare us for such a scenario. While the scientific idea itself is undoubtedly essential for a science/engineering-driven start-up, the preparation for the pitch made me realize that it is equally important, if not more, to convey to the potential investor the public interest brought by our idea, our grasp of the target market and our vision for the growth of the start-up. Last but not least, it was so much fun to work with Antonia, Tamara and Thomas “against the clock”.’
PRN 2021 Best talk award
At the end of May 2021, the Fachhochschule Nordwerstschweiz hosted the Polymer Replication on Nanoscale conference (prn-conference.com/program). The conference aims to provide an up-to-date overview on the state of the art and newest findings in R&D on polymer replication on the micro- and nanoscale. The virtual conference was attended by members from both academia as well as industry. Here, Thomas Mortelmans, PhD-student in the Laboratory of Micro-and Nanotechnology, had the honor to give an invited talk entitled: Thermoplastic 3D nanofluidic devices for biosensing. The presentation explained how different nanofabrication methods can be simultaneously used to achieve 3D nanoscale topography control in a cost-effective and up scalable manner. At the end of the conference, Thomas was awarded with the best talk award in the category of young scientists.
