Recherche sur le Covid-19

Au PSI, plusieurs projets se consacrent à des questions de recherche importantes autour du coronavirus Sars-CoV-2 et des maladies qui en résultent. Nous vous informons sur les activités et les projets, par exemple sur les analyses de tissus pulmonaires, sur la production de protéines et d'anticorps ou sur les idées de nouvelles recherches sur le Covid-19.

Tuning magnetoelectricity in a mixed-anisotropy antiferromagnet

Control of magnetization and electric polarization is attractive in relation to tailoring materials for data storage and devices such as sensors or antennae. In magnetoelectric materials, these degrees of freedom are closely coupled, allowing polarization to be controlled by a magnetic field, and magnetization by an electric field, but the magnitude of the effect remains a challenge in the case of single-phase magnetoelectrics for applications.

Wir freuen uns auf die neuesten Erkenntnisse und einen regen Austausch mit den drei Gästen und den Teilnehmenden!

Gas Attenuators

A compact gas attenuator for the SwissFEL ATHOS beamline realized using additive manufacturing

Gas attenuators are important devices providing accurate variation of photon intensity for soft X-ray beamlines. In the SwissFEL ATHOS beamline front-end the space is very limited and an innovative approach has been taken to provide attenuation of three orders of magnitude up to an energy of 1200 eV. Additive manufacturing of a differential pumping system vacuum manifold allowed a triple pumping stage to be realized in a space of less than half a meter. Measurements have shown that the response of the device is as expected from theoretical calculations.

A close look at temperature profiles during laser 3D printing

Operando X-ray diffraction was used to measure process zone temperatures in laser powder bed fusion and compared with finite element simulations.

MAMI beam test set-up

Beam test of pixel sensors at MAMI Mainz

We spent a week at the MAMI electron accelerator in Mainz testing MuPix11 pixel sensors. In particular we studied the behaviour at high rates, tested various operation points and took data for parametrising the sensor response in the simulation.

Welttag für kulturelle Diversität für Dialog und Entwicklung

Am 21. Mai ist der Welttag der kulturellen Vielfalt für Dialog und Entwicklung. Dieser Tag wurde ursprünglich von der UN-Generalversammlung im Jahr 2002 ausgerufen, um den Wert der Kulturen und des interkulturellen Dialogs für Frieden und nachhaltige Entwicklung zu würdigen. PSI-Forschende aus 64 Nationen arbeiten gemeinsam an dem Ziel, die Wissenschaft für eine bessere Zukunft voranzubringen. Heute feiern wir diese kulturelle Vielfalt, indem wir die Lieblingsgerichte von vier Forschenden des PSI vorstellen.

Deciphering the Mechanism of Crystallization of UiO-66 Metal-Organic Framework

Zirconium-containing metal-organic framework (MOF) with UiO-66 topology is an extremely versatile material, which finds applications beyond gas separation and catalysis.  By means of in situ time-resolved high-resolution mass spectrometry, Zr K-edge X-ray absorption spectroscopy, magic-angle spinning nuclear magnetic resonance spectroscopy, and X-ray diffraction it is showed that the nucleation of UiO-66 occurs via a solution-mediated hydrolysis of zirconium chloroterephthalates, whose formation appears to be autocatalytic.

Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel zone plate. This innovative approach enables the correction of the chromatic aberration suffered by both refractive and diffractive lenses over a wide range of X-ray energies. This groundbreaking development in X-ray optics have been just published in the scientific journal Light: Science & Applications.
