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.
Glycation of collagen: Quantifying rates
Collagen is abundant in the connective tissue of human beings, e.g. in tendons, ligament and cornea. Glycation of collagen distorts its structure, renders the extracellular matrix stiff and brittle and at the same time lowers the degradation susceptibility thereby preventing renewal. Based on models and with parameters determined from experimental data, we describe the glycation of type 1 collagen in bovine pericardium derived bio-tissues upon incubation in glucose and ribose. We hope that this contributes to a better quantitative understanding of the effects of diabetes on collagen.

Proteine auf Abstand
Mit einem Proteinfusionsverfahren, bei dem ein modularer Linker verwendet wird, ist es PSI-Forschenden gelungen, zwei nicht miteinander verbundene Proteindomänen in einem bestimmten Abstand und in einer bestimmten Ausrichtung miteinander zu verbinden. Diese Technologie könnte Anwendungen z.B. in der Impfstoffentwicklung ermöglichen oder die Kristallisation von Proteinen für die Arzneimittelentwicklung erleichtern. Darüber hinaus hat der Linker das Potenzial, als Bestandteil von Nanomaterialien auf Proteinbasis eingesetzt zu werden. Wenn Sie mehr über diese aufregende Technologie erfahren möchten, wenden Sie sich gern an uns.

Magnetic Bistability at a Record High Temperature in a Sub-Monolayer of Endohedral Fullerenes
A team of the Leibniz Institute for Solid State Research (IFW) from Dresden, Germany, led by Dr Alexey Popov has now demonstrated a record blocking temperature of 28 Kelvin at which the magnetic bistability still survives in a submonolayer of a chemically functionalized species of endofullerenes. In this research, X-ray magnetic circular dichroism measurements at low temperatures and high magnetic field at the X-Treme beam line are crucial. The results pave the way toward using such single-molecule magnets as information carriers or magnetic bits.

NET ZERO Day of the four RIs at Empa
Climate change is one of the biggest challenges humanity is facing. It requires an approach, in which competences and capacities in research are combined across Switzerland to develop solutions for a transformation of our society towards net zero CO2 emissions.
Towards in situ imaging of electrolyte physical and chemical changes in Li-ion batteries
The Lithium conducting electrolyte is a critical component of Li-ion batteries, as it has an important impact on performance and its durability, in particular in case of extreme environmental conditions. At low temperatures, a partial solidification can occur, while high temperatures can promote the degradation of the electrolyte. Using time-of-flight (ToF) neutron radiography, the possibility of imaging such changes in a fully non-invasive manner was demonstrated for the first time.

Direct evidence of cobalt oxyhydroxide formation on a LSCO perovskite water splitting catalyst
In situ and ex situ ambient pressure X-ray photoelectron spectroscopy have been used to investigate the solid-liquid interface of a LSCO water splitting catalyst. Experimental results, supported by theoretical simulations of the core-electron binding energy, detect the formation of cobalt oxyhydroxide under working conditions.

Temperature and Reaction Environment Influence the Nature of Platinum Species Supported on Ceria
The evolution of atomically dispersed platinum species on ceria has been investigated by means of ambient pressure X-ray photoelectron spectroscopy and X-ray absorption near edge structure spectroscopy. Experimental results, supported by the theoretical simulation of the phase diagram, show that atomically dispersed species evolve towards nanoparticles during the activation of the catalysts. Such an evolution is influenced by the temperature and the reaction environment.

Magnetic Field Induced Quantum Spin Liquid in the Two Coupled Trillium Lattices of K2Ni2(SO4)3
Quantum spin liquids are exotic states of matter that form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale of the magnetic interactions. Three-dimensional cases are especially challenging due to the significant reduction of the influence of quantum fluctuations. Here, we report the magnetic characterization of K2Ni2(SO4)3 forming a three-dimensional network of Ni2+ spins.

Unveiling unconventional magnetism at the surface of Sr2RuO4
Materials with strongly correlated electrons often exhibit interesting physical properties. An example of these materials is the layered oxide perovskite Sr2RuO4, which has been intensively investigated due to its unusual properties. Whilst the debate on the symmetry of the superconducting state in Sr2RuO4 is still ongoing, a deeper understanding of the Sr2RuO4 normal state appears crucial as this is the background in which electron pairing occurs. Here, by using low-energy muon spin spectroscopy we discover the existence of surface magnetism in Sr2RuO4 in its normal state.

ReMaP – Current status of energy research
With its Energy Strategy 2050 Switzerland aims – beside other goals – to promote the use of domestic renewable energy and to develop the electricity power grid, which plays a decisive role in the upgrading of the system of electricity power supply. A lot of research needs to be done to achieve these ambitious goals. An important research project in this area is ReMaP and its status quo was presented at the Paul Scherrer Institute PSI on 28 September.

Aging of Diesel oxidation catalysts
Diesel oxidation catalysts mitigate toxic emissions in heavy duty vehicles but they age during operation due to deposition of chemical elements and structural changes in the active Platinum group metals. Here, vehicle aged catalysts have been characterised in detail to better understand the catalyst deterioration. Such understanding have been applied in the attempts to replicate the aging in the lab.
